[Docket No. NHTSA-2021-0003]
RIN 2127-AM06
Occupant Protection for Vehicles With Automated Driving Systems
AGENCY: National Highway Traffic Safety Administration (NHTSA),
Department of Transportation.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This final rule amends the occupant protection Federal motor
vehicle safety standards (FMVSSs) to account for future vehicles that
do not have the traditional manual controls associated with a human
driver because they are equipped with Automated Driving Systems (ADS).
This final rule makes clear that, despite their innovative designs,
vehicles with ADS technology must continue to provide the same high
levels of occupant protection that current passenger vehicles provide.
The occupant protection standards are currently written for
traditionally designed vehicles and use terms such as ``driver's seat''
and ``steering wheel,'' that are not meaningful to vehicle designs
that, for example, lack a steering wheel or other driver controls. This
final rule updates the standards in a manner that clarifies existing
terminology while avoiding unnecessary terminology, and, in doing so,
resolves ambiguities in applying the standards to ADS-equipped vehicles
without traditional manual controls. In addition, this final rule
amends the standards in a manner that maintains the existing regulatory
text whenever possible, to make clear that this rule maintains the
level of crash protection currently provided occupants in more
traditionally designed vehicles. This final rule is limited to the
crashworthiness standards to provide a unified set of regulatory text
applicable to vehicles with and without ADS functionality.
DATES: Effective date: September 26, 2022. Optional early compliance
(i.e., prior to the effective date) is permitted. Petitions for
reconsideration must be received on or before May 16, 2022. The
incorporation by reference of certain publications listed in the rule

I. Executive Summary
NHTSA has been evaluating its Federal Motor Vehicle Safety
Standards (FMVSSs) to identify where concepts or terminology used in
the standards do not account for the designs that the agency expects,
and industry confirms, could accompany certain vehicles equipped with
Automated Driving Systems (ADSs).\1\ NHTSA has detailed in previous
rulemaking notices the activities it has undertaken in its evaluation.
These activities include initial evaluation of the FMVSSs,\2\ issuing
Federal Register notices soliciting input from stakeholders,\3\
research on possible options available to
[[Page 18561]]
the agency to amend the FMVSSs,\4\ and public discussions with
stakeholders.\5\

---------------------------------------------------------------------------
This prior work resulted in the agency's March 30, 2020, notice of
proposed rulemaking (NPRM) underlying this final rule.\6\ The NPRM
proposed to revise its current crashworthiness \7\ (200-Series) FMVSSs
to amend terms or other text to account for the unconventional interior
designs that are expected to be present in certain ADS-equipped
vehicles. An example of such an unconventional interior design would be
those that lack driving controls.
---------------------------------------------------------------------------
\6\ 85 FR 17624.
\7\ Throughout this notice, NHTSA uses ``crashworthiness'' and
``occupant protection'' interchangeably because the agency considers
the 200-Series FMVSSs to be focused on both.
---------------------------------------------------------------------------
In the proposal, NHTSA proposed to amend the existing FMVSSs in a
way that maintains the occupant protection performance currently
required by the 200-Series FMVSSs while amending the wording that has
or will become obsolete as applied to new designs, and to clarify for
manufacturers developing ADS-equipped vehicles the application of a
particular FMVSS to their vehicle. The NPRM also ensured these
revisions accounted for dual-mode ADS-equipped vehicles (ADS-equipped
vehicles that also have a conventional driving mode), as defined by SAE
International (SAE).\8\ NHTSA also sought to remove requirements for
which a safety need does not exist.
---------------------------------------------------------------------------
\8\ An [ADS-Equipped] Dual-Mode Vehicle is defined as ``[a] type
of ADS-equipped vehicle designed for both driverless operation and
operation by a conventional driver for complete trips.'' SAE
J3016_201806 Taxonomy and Definitions for Terms Related to Driving
Automation Systems for On-Road Motor Vehicles.
---------------------------------------------------------------------------
NHTSA received 45 comments on the NPRM.\9\ The proposal garnered
comments from vehicle and equipment manufacturers, ADS developers,
industry associations, consumer advocates, advocates for persons with
disabilities, States, insurance organizations, a university, an oil
independence advocacy group, and members of the general public. Many
commenters supported the proposal and the use of definitional and
textual changes to achieve the goals of the NPRM, though numerous other
commenters argued that the agency's focus on this issue was premature.
Regardless of their general position on the rule, most commenters did
support NHTSA's suggestion that, to the extent any changes were
finalized, they should be done in way that minimized the complexity of
the changes to the FMVSSs.
---------------------------------------------------------------------------
\9\ Docket No. NHTSA-2020-0014. NHTSA received an additional 5
comments that were determined to be completely unrelated to this
notice (#4, #5, #6, #18, #52), and 1 duplicate submission (#42).
---------------------------------------------------------------------------
The agency acknowledges that uncertainty continues to exist around
the development and potential deployment of ADS-equipped vehicles.
Nevertheless, NHTSA believes it is appropriate to finalize this action
at this time in anticipation of emerging ADS vehicle designs that NHTSA
has seen in prototype form. The current designs generally involve
forward-facing row seating \10\ and vehicles without manual driving
controls. NHTSA has designed this final rule to minimize the changes to
the FMVSSs and to maintain the level of occupant protection currently
provided in all FMVSS compliant vehicles. This final rule provides
regulatory certainty that, despite their innovative designs, vehicles
with ADS technology must continue to provide the same high levels of
occupant protection that current passenger vehicles provide. This final
rule adopts most of the provisions included in the NPRM, with some
exceptions summarized in the next section.
---------------------------------------------------------------------------
\10\ Applying the occupant protection standards to forward-
facing seating is straightforward since the standards are generally
designed with forward-facing seating in mind. In contrast, applying
the standards to side-facing, campfire or other seating
configurations is more complex and will involve more research, which
is currently underway, and standard development.
---------------------------------------------------------------------------
Differences Between the NPRM and Final Rule
The differences between the NPRM and the final rule are generally
minor and are fully explained in the relevant sections in this
document. Some of the more substantive changes in this final rule are
as follows.
NHTSA believes that children should not occupy the
``driver's'' position when the vehicle is operating in ADS mode and
steering controls are present, given that the driver's seating position
has not been designed to protect children in a crash. For example, the
required limit on the rearward displacement of the steering column and
forcefulness with which the air bag deploys have been optimized for
adults and could pose a safety risk to children. The NPRM proposed that
ADS vehicles must suppress vehicle motion when: (1) The vehicle
contains a driver's seat (i.e., manually operated driving controls are
available, but not necessarily functional during ADS operation); (2)
the occupant of the driver's seat is classified by the air bag system
as a child; and (3) the vehicle is in an operational state that does
not require a driver (i.e., where the ADS is in control of the driving
task). After review of the comments, for now, NHTSA has decided against
adopting a vehicle motion suppression requirement in these
circumstances. The agency would like to know more about the relative
risk of a child seated in the ``driver's'' position as compared to the
passenger position and whether there are other ways of addressing this
safety concern than a requirement to suppress vehicle motion
completely. The agency would also like to explore any necessary
refinements to occupant detection and low risk deployment requirements
and test procedures for the driver's seat.
Proposed regulatory text would have changed the front row
seat compartmentalization occupant protection requirements for large
school buses (gross vehicle weight rating over 4,536 kg (10,000 lb.))
in ways not intended by NHTSA. Such text is not adopted by this final
rule.
NHTSA has modified FMVSS No. 208, Occupant crash
protection, to be clearer in the protections that are required for
inboard seating positions in the front row of ADS-equipped vehicles.
This final rule modifies the application section of FMVSS
Nos. 212, Windshield mounting, and 219, Windshield zone intrusion, to
make clear these standards exclude occupant-less vehicles, since these
standards meet no safety need when there are no occupants to protect.
NHTSA has decided not to move forward at this time with
changing the FMVSS No. 226, Ejection mitigation, requirements for the
ejection mitigation countermeasure readiness indicator. The agency will
consider amendments to controls and displays in a separate rulemaking.
Minor differences between the NPRM and this final rule are
discussed in the appropriate sections in this preamble. Some of these
differences include:
Moving the definition of ``seat outline'' from FMVSS No.
226 to Sec. 571.3, Definitions (see Section IV.a.7 of this preamble);
Slightly revising the term used to describe occupant-less
vehicles, to refer to at least ``one person'' rather than referring to
``a designated seating position,'' (see Section V.a of this preamble);
and
In FMVSS No. 208, correcting a missed revision indicating
there can be multiple front seat passengers (S19.2.2(e)) (see Section
VI.f of this preamble), and adopting a wording change to clarify the
air bag suppression
[[Page 18562]]
test procedure (S20.2, S22.2, S24.2) (see Section VI.a of this
preamble).
As was the case for the NPRM, to illustrate the precise changes
that are being made within the context of the full regulatory text, we
are providing in the docket for this rulemaking a document that
contains the full regulatory text of each modified standard included in
this final rule. The text is color coded in the following manner; blue
bold underline (text added by the NPRM), red strikeout (text deleted by
the NPRM), green bold underline (text added by the final rule), orange
strikeout (text deleted by the final rule). (The information is
provided for illustration purposes for the convenience of readers and
does not change the amendments provided in the amendatory text of this
final rule.)
Guiding Principles
In the NPRM, NHTSA expressed certain ``guiding principles'' for
this rulemaking, which continue to be relevant in this final rule.
First, the amended FMVSS requirements in this final rule are intended
to maintain the level of crashworthiness performance in vehicles with
and without ADS functionality, including ADS-equipped vehicles that
also have a conventional driving mode (dual-mode ADS vehicles). The
level of performance required by the amended FMVSSs is just as
appropriate for ADS-vehicles as it is for non-ADS vehicles in
protecting the public against unreasonable risk of death or injury in a
crash.\11\ More specifically, NHTSA sought to maintain the level of
safety currently provided to occupants by applying the crash test
performance requirements for the right front outboard occupant to the
left front outboard occupant of ADS-vehicles, wherever possible.
Similarly, occupants seated behind driving controls in ADS-vehicles
(dual-mode ADS vehicles) will be protected just as drivers are today.
Second, NHTSA sought to amend its standards to account for new designs,
and to clarify for manufacturers developing ADS-equipped vehicles,
particularly those that lack manual controls, that the standards apply
to their vehicles. In short, NHTSA sought to clarify that a
manufacturer of ADS-equipped vehicles must continue to apply occupant
protection standards to its vehicles even if manual steering controls
are not installed in the vehicle. Finally, for the convenience of
readers and those familiar with the standards, NHTSA sought to amend
the requirements in a manner that minimized the changes to the
regulatory text of the standards.
---------------------------------------------------------------------------
\11\ 49 U.S.C. 30102(a)(10) (from definition of ``motor vehicle
safety'').
---------------------------------------------------------------------------
This final rule is purposefully limited in scope based on the
bounds listed below.
1. This final rule only applies to ADS-equipped vehicles that have
seating configurations similar to non-ADS vehicles, i.e., forward-
facing front seating positions (conventional seating). Thus, NHTSA
focused on conventional seating in this rulemaking, noting that
additional research is necessary to understand and address different
safety risks posed by vehicles with unconventional seating arrangements
(e.g., rear-facing seats or campfire seating).
2. This final rule addresses ADS-equipped vehicles designed
exclusively to carry property (``occupant-less vehicles'') by amending
the application of existing crashworthiness requirements for these
vehicles, as appropriate. This final rule does not address potential
vehicle-to-vehicle compatibility issues related to occupant-less
vehicles, as the existing standards do not test for this issue.\12\
---------------------------------------------------------------------------
\12\ Vehicle-to-vehicle compatibility refers to how well two
vehicles match up in a two-vehicle crash. Vehicles that are heavier,
with higher ground clearance, and with stiffer front ends can pose a
higher injury risk to occupants in smaller cars. Currently NHTSA has
no evidence of compatibility issues with occupant-less vehicles, but
NHTSA is researching this area.
---------------------------------------------------------------------------
3. With one exception, this final rule refrains from amending
requirements relating to telltales and warnings, as that area has
implications beyond the 200-Series standards and is a subject of
continuing NHTSA research. The exception to this is the air bag
suppression telltale, which we believe is reasonable to address now.
This is described further in section VI.b of this preamble.
Tables of Costs and Benefits
This rule will eliminate the need for ADS-equipped -vehicle
manufacturers to equip vehicles with redundant manual driving controls
in vehicles that do not have manual driving capabilities, to comply
with FMVSS. In turn, the cost impacts of this rule will be driven
predominantly by the per-vehicle costs savings to each vehicle that
would no longer need certain manual controls and the number of vehicles
produced each year that will be produced without those controls. The
Agency has reliable information on the former category, given that we
generally know the current costs of this equipment, but can only
estimate the broader effects. Thus, NHTSA calculated ranges of
estimates of cost impacts using a variety of logical assumptions. NHTSA
calculated the impact of the final rule on costs by analyzing
production cost savings arising from forgoing the installation of
manual steering controls. These cost savings are partially offset by
incremental costs associated with augmenting safety equipment in the
left front seating position to make that position equivalent to the
right front seating position.
NHTSA estimates that this rule would save approximately $995 per
vehicle, as explained in greater detail in the RIA. NHTSA has conducted
an analysis that shows how these cost savings would look if these types
of vehicles entered the fleet to at least some degree. The results of
this estimate show the present value of the final rule's estimated
year-2050 savings to ADS-DV manufacturers and consumers, based on the
assumption that there will be approximately 5.8 million affected
vehicles, at a three-percent discount rate equal to $2.5 billion. At a
seven-percent discount rate, the estimated year-2050 savings has a
present value equal to approximately $0.9 billion, as presented in
Table 1:
Table 1--Estimated Total Monetized Annual Cost Impacts

2022).
30%.................................. 7% (Discounted back to -0.6
2022).
------------------------------------------------------------------------
These estimates represent an upper bound, in which ADS-DVs do not
compete with dual-mode ADS-equipped vehicles (i.e., 5.8 million ADS-DVs
are sold in 2050, with each including a measure of production cost
savings associated with forgoing manual steering controls). Under the
alternative EIA scenario in which one percent of new vehicle sales in
2050 are comprised of ADS-DVs, the corresponding estimates are: A
present value in 2022 of approximately $60 million at a three-percent
discount rate; and approximately $20 million at a seven-percent
discount rate.
As a sensitivity analysis, NHTSA also considered an alternative
case, in which ADS-DV sales in 2050 are reduced by 30 percent relative
to the baseline, with the change in sales representing sales of
[[Page 18563]]
dual-mode ADS-equipped vehicles. This represents a case in which: (1)
ADS-DV sales are split between approximately one-sixth fleet sales and
five-sixths private ownership, per the EIA scenario; (2) one-seventh of
fleet ADS-DV purchases in the baseline analysis are allocated to dual-
mode vehicle sales (i.e., approximately 1/7 x 1/6 of all ADS-DV sales);
and (3) one-third of private ADS-DV purchases in the baseline analysis
are allocated to dual-mode vehicle sales (i.e., approximately 1/3 x 5/6
of all ADS-DV sales). Under this alternative scenario, savings to ADS-
DV manufacturers and consumers under the final rule would be
approximately $1.7 billion at a three-percent discount rate, and
approximately $0.6 billion at a seven-percent discount rate.
There are no other quantified benefits associated with this final
rule. NHTSA acknowledges that this final rule may impact safety and
fuel consumption and would likely generate benefits associated with
incremental producer and consumer surplus beyond the production cost
savings quantified above. This final rule may also generate benefits
that could lead to increased safety, reductions in administrative
burden, and reductions in manufacturer uncertainty, though these
benefits are also unquantified.
The final rule is assumed to have no effect on the per-mile risk of
travel in ADS-DVs, as it does not revise, remove, or establish anything
associated with their safety performance. That is, the removal of
manual steering controls is not assumed to offer any direct safety
benefit or detriment for travel in ADS-DVs. However, it is feasible
that changes in ADS-DV demand associated with the final rule (e.g., due
to changes in vehicle design or decreases in cost) could increase the
use of ADS-DVs. In turn, safety outcomes associated with the final rule
would be equal to the net effects of: (1) Changes in per-mile fatality
and injury risk for travel that is shifted from conventional vehicles
to ADS-DVs; and (2) incremental fatalities and injuries for travel in
ADS-DVs that would not have taken place in any vehicle otherwise. It is
difficult to project net safety impacts associated with the final rule
without information on: (1) Per-mile fatality and injury risk for ADS-
DVs and conventional vehicles over time; and (2) demand for travel in
ADS-DVs and conventional vehicles as a function of ADS-DV price and
design attributes. NHTSA continues to engage in various research,
regulatory, and enforcement efforts associated with the safety of the
automated driving system itself, but those activities are outside the
scope of this rulemaking.
The final rule could affect per-vehicle fuel consumption by
changing the mass of ADS-DVs. NHTSA expects ADS-DV mass to either
decrease (due to the removal of currently required equipment) slightly
or remain essentially unchanged (due to the addition of automated
steering components that offset the mass savings of the removed
equipment) under the final rule. NHTSA acknowledges that, in principle,
ADS-DV mass could increase (if vehicle seating configurations and
amenities are changed sufficiently when exploiting the reduction in
design constraints when removing manual steering controls) under the
final rule. In any event, current corporate average fuel economy (CAFE)
requirements are based on a vehicle's ``footprint,'' and thus any
change in a vehicles mass will not affect a manufacturer's obligations
under that program. Finally, as stated in the NPRM, NHTSA has not
attempted to address the revisions that may be necessary to provide
regulatory certainty for manufacturers that wish to self-certify ADS-
equipped vehicles with unconventional seating arrangements.
The final rule would lead to a reduction in the number of standards
from which manufacturers of ADS-DVs would have to seek exemptions. The
reduction in exemption requests would be associated with a reduction in
administrative costs for both manufacturers and NHTSA. NHTSA does not
have sufficient information to establish a specific estimate of
administrative cost savings. However, the cost savings would be
expected to be small relative to the production cost savings associated
with the rule.
A less tangible, but still important, expected impact of the final
rule would be a reduction in uncertainty for manufacturers of ADS-
equipped vehicles. The final rule provides clarity to manufacturers on
constraints to developing FMVSS-compliant ADS-equipped vehicles. In
turn, developmental paths for ADS-equipped vehicles could be
implemented with greater precision and efficiency. The reduction in
uncertainty could reduce not only the costs associated with
manufacturing ADS-equipped vehicles, but also the time it would take to
bring these vehicles to the market. An accelerated development timeline
would be a benefit both to manufacturers and consumers.
II. NPRM
On March 30, 2020, NHTSA issued an NPRM that proposed modifications
to certain terms and other regulatory text in the 200-Series FMVSSs to
account for ADS-equipped vehicles and certain interior designs that are
expected to be present in these vehicles, including the lack of driving
controls.\13\ The NPRM also included modifications to the regulatory
text to take into account some dual-mode ADS-equipped vehicles.\14\ The
NPRM sought to resolve whether occupant protection requirements ought
to apply to occupant-less vehicles.
---------------------------------------------------------------------------
\13\ 85 FR 17624. As discussed below, however, the NPRM assumed
the vehicles will have conventional forward-facing seating.
\14\ An [ADS-Equipped] Dual-Mode Vehicle is defined as ``[a]
type of ADS-equipped vehicle designed for both driverless operation
and operation by a conventional driver for complete trips.'' SAE
J3016_201806 Taxonomy and Definitions for Terms Related to Driving
Automation Systems for On-Road Motor Vehicles.
---------------------------------------------------------------------------
NHTSA's proposal sought to account for certain vehicle designs
expected to accompany ADS-equipped vehicles in a manner that minimized
textual additions and modifications to the 200-Series FMVSSs. The
proposal discussed existing terms used in the standards that, through
their use, made uncertain how regulatory text applies to vehicle
designs that did not incorporate such terms. The proposal discussed
existing terms that, by virtue of new vehicle designs, could be
misunderstood, and defined them to clarify their meaning for ADS-
equipped vehicles. The NPRM proposed a few new terms and definitions
and proposed relocating other terms and definitions. The NPRM proposed
to modify regulatory text to address situations where there may be no
driver seat, but multiple outboard passenger seats. The agency proposed
to consider any left outboard seat that does not have immediate access
to traditional manual controls (``manually operated driving controls'')
as a ``passenger seat'' and mirror the test procedures and requirements
from the right side.
FMVSS No. 208, Occupant crash protection, is a primary focus of
this rulemaking, as it is one of NHTSA's most complex standards, and
many of this standard's performance requirements and test procedures
were written with references to the ``driver's'' seating position. This
emphasis on the driver's position in the standard reflected the fact
that, with conventional (i.e., non-ADS) vehicles, the driver's seat
should always be occupied by an individual of legal driving age during
operation. For our discussions in this document we will typically refer
to these individuals as adults, although they may in some cases be
legally minors. The NPRM discussed the treatment of advanced air bags
and
[[Page 18564]]
advanced air bag suppression telltales \15\ in ADS-equipped vehicles
with two front outboard passenger seats. The NPRM proposed to require a
separate telltale for each front outboard passenger seat, which must be
visible from each front outboard seat. The NPRM addressed FMVSS No.
208's seat belt requirements for ``medium-sized'' buses (with a gross
vehicle weight rating (GVWR) between 4,536 kilograms (kg) (10,000
pounds (lb.)) and 11,793 kg (26,000 lb.)) and school buses (GVWR
greater than 4,536 kg (10,000 lb.)). For such buses equipped with ADS
without a driver's seat, NHTSA proposed that all front seats meet the
protection requirements that must currently be met by the driver's
seat.
---------------------------------------------------------------------------
\15\ The term ``telltale'' is defined in FMVSS No. 101; Controls
and displays, as ``an optical signal that, when illuminated, shows
the actuation of a device, a correct or improper functioning or
condition, or a vehicle system's failure to function.'' The term is
used in many other FMVSSs and is used in FMVSS No. 208 for an
indicator of air bag operational status as a function of the
occupant detection system of the seat.
---------------------------------------------------------------------------
The NPRM proposed to streamline the 200-Series FMVSSs so that
requirements would not apply when the ADS-configured vehicle posed no
safety need for the requirement. For example, the proposal took the
position that, when there is not a steering wheel or steering column in
a motor vehicle, FMVSS Nos. 203, Impact protection for the driver from
the steering control system, and 204, Steering control rearward
displacement, would not apply. Similarly, the NPRM proposed not to
apply occupant protection standards to vehicles designed solely to
carry cargo, rather than occupants (``occupant-less'' vehicles).\16\
This was accomplished by proposing to alter the ``application'' section
of various FMVSSs to indicate that the standards only applied to a
``truck'' with at least one designated seating position (DSP).\17\ The
NPRM analysis concluded that this change was only required for FMVSS
Nos. 201, Occupant protection in interior impact, 205, Glazing
material, 206, Door locks and door retention components, 207, Seating
systems, 208, Occupant crash protection, 214, Side Impact protection,
216a, Roof crush resistance; Upgraded standard, and 226, Ejection
mitigation.
---------------------------------------------------------------------------
\16\ We note that a vehicle designed to carry standee passengers
(e.g., a transit shuttle) would fall under one of NHTSA's other
vehicle classifications.
\17\ ``Designated seating position'' is defined in 49 CFR 571.3.
Generally described, a DSP is a seat location that has a seating
surface width of at least 330 millimeters (13 inches) as measured in
the manner described in the definition.
---------------------------------------------------------------------------
High-Level Summary of Comments on Overall Approach and Need for
Rulemaking
In response to the NPRM, NHTSA received 45 comments from vehicle
and equipment manufacturers and ADS developers, industry associations,
consumer advocates, advocates for persons with disabilities, States,
insurance organizations, a university, an oil independence advocacy
group, and members of the general public. Generally, most commenters
supported the proposal, the revision of terms and use of definitional
and textual changes to achieve the goals of the NPRM, and the agency's
approach to minimize the complexity of the changes to the FMVSSs.\18\
However, various other commenters, particularly certain non-
governmental organizations, raised concerns about the agency's general
approach to ADS regulation and the prioritization of this and similar
rules, though many of these commenters had only minor comments
concerning specific proposed technical changes.
---------------------------------------------------------------------------
\18\ An additional 5 comments were received that were determined
to be completely unrelated to this notice (#4, #5, #6, #18, #52),
and 1 duplicate submission (#42).
---------------------------------------------------------------------------
Approximately 25 commenters across all commenter types agreed that
there is a need for the proposal, and, of these, approximately 17
commenters stated they agreed with the general approach. For example,
General Motors (GM) commented that it supports the approach used in the
NPRM and that ``when finalized into a final rule, [it] will provide
needed regulatory certainty for certification, reduce certification
costs and minimize (but not completely eliminate) the need for future
NHTSA interpretation or exemption requests related to ADS-equipped
vehicles.'' Waymo stated that the proposal would not reduce any
protections for automated vehicles without manual controls and strongly
supported the limitations in scope of the NPRM ``to crashworthiness
standards to conventional occupant seating arrangements.'' The Alliance
for Automotive Innovation (Alliance) stated that the rulemaking will
work towards ``maintaining motor vehicle safety'' and ``reduce the need
to rely on the administratively complex and time-consuming FMVSS
exemption process.''
Several commenters, though, questioned the need for the rulemaking
action. The Center for Auto Safety (CAS) argued that a better
allocation of limited government resources would be to focus on the
``nearer-term technology improvements with immediate impact on the
safety of occupants of conventional vehicles, pedestrians, and other
vulnerable road users.'' CAS stated that such an approach was more
appropriate because ``fully autonomous driving system-equipped vehicles
[. . .] do not exist at this time.'' CAS also asserted that NHTSA
should not permit traditional manual controls to be removed from
vehicles ``until at least equivalent safety [of ADS-equipped vehicles]
is proven.'' CAS stated that such controls ``might be deployable only
as needed but are an absolute necessity for the many conceivable
foreseen and unforeseen safety-critical situations that ADS-equipped
vehicles will encounter.'' The National Safety Council (NSC) stated
that ``shifting focus from tried-and-true vehicle standards is the
wrong approach and evaluating the removal of those standards is
premature at this time. As most ADS vehicle designs that might benefit
from a revision of FMVSS standards are still on the drawing boards and
unforeseen issues are certain to arise, eliminating current standards
at this point is hasty.'' NSC argued that NHTSA should redirect
resources and prioritize requiring advanced driver assistance systems
(ADAS) and other technologies in vehicles. Consumer Reports (CR) also
``question[ed] the present focus of the agency on `removal of
regulatory barriers' rather than on developing and implementing
standards for proven safety technologies,'' though CR also stated that
it ``appreciate[s] the Agency's targeted approach on this topic'' and
that the narrow scope of the NPRM ``is appropriate.'' The Insurance
Institute for Highway Safety (IIHS) expressed concern that ``the
current Notice of Proposed Rulemaking (NPRM) creates a path for
deploying into the market ADS-controlled vehicles without regulations
that establish the ground rules for the safe behavior of ADS,'' Though
it also stated that ``modifications proposed by NHTSA likely will be
helpful to the entities developing automated driving systems (ADS) and
the vehicles that will be controlled by ADS'' and that the ``changes
answer some questions about how the occupants of ADS-controlled
vehicles should be protected in the event of a crash.''
Agency Response
NHTSA is sensitive to concerns raised regarding prioritizing
rulemakings and other activities that emphasize other technologies,
such as advanced driver assistance systems (ADAS), instead of focusing
on vehicles that remain in development. However, in the case of this
rulemaking, the agency focused appropriate resources to address a
narrow question. Further, NHTSA has
[[Page 18565]]
determined it is appropriate to proceed with this final rule at this
time, as it will provide ADS manufacturers with certainty on how to
comply with these FMVSSs and reaffirm the application of occupant
protections standards to vehicles equipped with ADS. Thus, this final
rule will have the limited effect of providing clarity on the specific
issues addressed here, which will, at the very least, ensure that
vehicles with ADS technology provide the same high levels of occupant
protection that current passenger vehicles provide. Taking this action
now will make clear that the crashworthiness standards apply to
vehicles with ADS technologies.
We also note that, in addition to this action, we have commenced
rulemaking and other action on ADAS technologies. In the Spring 2021
Unified Agenda of Regulatory and Deregulatory Actions, NHTSA announced
two rulemakings to require emergency braking performance for heavy and
light vehicles and to require pedestrian automatic emergency braking
performance in light vehicles.\19\ Furthermore, the agency is working
on updates to its New Car Assessment Program (NCAP 5-star safety
ratings program) to include additional modern vehicle safety
technologies that can address crashes and promote safer behaviors.
Thus, the agency is actively engaged in actions related to ADAS.

The purpose of the National Traffic and Motor Vehicle Safety Act
(Safety Act), which NHTSA, by delegation, is tasked with administering,
is to reduce traffic crashes and their resulting deaths and injuries,
through carrying out research and establishing FMVSS.\20\ In
establishing FMVSSs, NHTSA sets minimum performance standards that are
objective and practicable, and that protect the public against an
unreasonable risk of crashes occurring, and death or injury in the
event a crash does occur.\21\ This final rule is consistent with the
goals of the Safety Act by modifying the FMVSSs to account for vehicle
designs that NHTSA anticipates will arise with deployment of ADS-
equipped vehicles, in a manner that provides occupants with at least
the same protections afforded by existing standards that the agency has
already found meet the need for motor vehicle safety.

Although NHTSA understands concerns that this final rule is
premature given the current state of ADS-equipped vehicle development,
the agency has received many requests from industry for information to
assist them in determining how existing FMVSSs apply to ADS-equipped
vehicles developed without traditional manual controls (e.g., steering
wheels) and other unconventional vehicle designs. In response to these
requests, NHTSA conducted a preliminary analysis of the potential
unintended barriers to these vehicle designs,\22\ issued requests for
comment, held public meetings, and initiated rulemaking proceedings on
the topic--including this rulemaking--to gather as much information as
possible on how best to approach modernizing the FMVSS to account for
these vehicles.

---------------------------------------------------------------------------
There also continues to be progress toward development of ADS-
equipped vehicles. NHTSA knows of dozens of testing and development
activities taking place in more than 40 States and the District of
Columbia, many of which involve ADS-equipped vehicles that lack
manually operated driving controls.\23\ In addition, one manufacturer
of small, low speed, occupant-less ADS delivery vehicles received a
temporary exemption from NHTSA to deploy up to 2,500 vehicles per year
for two years.\24\ These activities, and the advancements toward
development of ADS-equipped vehicles, have created an opportunity for
new vehicle designs that warrants evaluation of current FMVSSs.

other petitions for exemption for ADS-equipped vehicles that would
lack manually operated driving controls. However, the agency has
only requested comment on one of these petitions, which was later
withdrawn. The agency is currently developing notices of receipt for
the two other petitions it received, including GM's updated
petition. See https://www.reuters.com/article/us-autonomous-cruise-nhtsa-idUSKBN2762SP.
---------------------------------------------------------------------------
When NHTSA promulgated most of the current FMVSSs, the agency did
not consider the sorts of vehicle designs that would be possible if a
vehicle could operate without human intervention. Today, an increasing
number of companies are developing technologies to make that idea a
reality. NHTSA is issuing this final rule to amend terminology,
definitions, and other nomenclature found in the relevant FMVSS that
inadvertently and unnecessarily impede the unconventional vehicle
designs described by manufacturers.
NHTSA identified the narrow scope of the NPRM clearly and has
retained that scope for this final rule. Although the agency is
sympathetic to many of the suggestions from CAS, CR, NSC and IIHS that
NHTSA should focus on other vehicle safety issues and technologies, the
agency believes it remains appropriate to finalize today's action on
the narrow grounds identified in the NPRM, while continuing its other
research and ongoing rulemaking actions on the issues identified by
those commenters, including those related to ADS performance and ADAS
technologies. Issues related to agency allocation of resources are also
outside the scope of this final rule.
NHTSA also disagrees with the IIHS assertion that this final rule
alone creates a path for ADS deployment. NHTSA's existing FMVSSs do not
prevent the deployment of ADS in vehicles configured like traditional
vehicles (i.e., equipped with manually operated driving controls), when
the vehicles meet all applicable FMVSSs. If the vehicle can be
certified as meeting the FMVSSs, it can be deployed with ADS regardless
of issuance of this final rule. This final rule simply makes targeted
changes to the FMVSSs to account for certain vehicle designs that NHTSA
has seen from some manufacturers or has otherwise been made aware. In
addition, this final rule only addresses the crashworthiness standards.
As the agency continues to assess how and whether to change other
relevant FMVSSs in response to these types of vehicles, at this stage,
an ADS-equipped vehicle may still be required to petition for and
receive an exemption from NHTSA to be manufactured for sale, sold,
offered for sale, introduced or delivered for introduction in
interstate commerce, or imported into the United States.\25\

This final rule is substantially similar to the NPRM, with some
alterations resulting from consideration of the comments. A summary of
the substantive differences between the NPRM and final rule was
provided in Section I of this preamble.
III. Introduction to This Final Rule
This final rule preamble is organized by critical subject matter.
First, the rule addresses subjects that affect all 200-Series FMVSSs,
such as changes to the
[[Page 18566]]
terminology used in the standards. For example, the agency is defining
some terms already used in many of the 200-Series FMVSSs to account for
ADS-equipped vehicles (e.g., ``driver's designated seating position,''
``passenger seating position''), or is adopting new definitions as
appropriate (``manually operated driving controls,'' ``steering
control''). These changes to nomenclature provide clarity about how the
crashworthiness FMVSSs apply to ADS-equipped vehicles and seek to amend
the FMVSSs to include these new vehicle designs. Another issue that
affects all 200-Series FMVSSs is the way in which the standards use
features such as the ``driver's seat,'' ``passenger seat,'' and
``steering controls'' as spatial references to describe where things
are located within the vehicle. This final rule amends the terms so
that the spatial references make sense as applied to the interior
designs of ADS-equipped vehicles, which may, for example, lack a
driver's seat and have an additional passenger seat instead. Other
issues of general significance include clarifications regarding how the
200-Series FMVSSs apply to vehicles that can be operated by both ADS
and by a steering control (dual-mode vehicles), and how some test
procedures pertain to vehicles that do not have components referenced
therein (e.g., a manual parking brake mechanism).
Second, this final rule achieves an objective of the agency with
regards to ``occupant-less vehicles,'' by tailoring the 200-Series
FMVSSs to exclude vehicles that are intended not to have human
occupants. Occupant-less vehicles are designed for the transportation
of property, not people, and have no DSPs. The agency has determined
that the original safety need of the 200-Series FMVSSs no longer exists
when there are no occupants to protect. A more fulsome discussion of
this topic is provided in section V of this preamble.
Third, this final rule preamble discusses amendments to terminology
used in certain FMVSSs, and focuses on FMVSS No. 208 as a critical
subject, as many of the performance requirements of this standard were
written with reference to the driver's and passenger's seating
positions. This final rule discusses changes to substantive
requirements of the standard resulting from those revisions to
terminology, such as the treatment of advanced air bags and advanced
air bag suppression telltales in ADS-equipped vehicles, lockability
requirements, and changes to FMVSS No. 208's seat belt requirements for
medium-sized buses and large school buses following the removal of the
term ``driver.''
Fourth, after the FMVSS No. 208 discussion, this final rule
discusses amendments to other FMVSSs.
Lastly, the final rule discusses the effective date and cost
impacts of the rule.
IV. Implications
a. New and Current Terms and Definitions
1. NPRM's Approach to Driver Definition
In the NPRM, NHTSA proposed to define, modify, or relocate existing
terms and proposed new terms both to clarify application of the 200-
Series FMVSSs to ADS-equipped vehicles and to facilitate the
implementation of other proposed regulatory changes. However, NHTSA did
not propose to amend the definition of ``driver'' in 49 CFR 571.3 to
include ADS, and it did so intentionally. NHTSA cited four primary
reasons for this decision. First, NHTSA believed it would not be
appropriate to consider changes to such a fundamental and ubiquitous
concept (``driver'') in a rulemaking that focused solely on the 200-
Series without completing the additional research necessary to address
implications for those other FMVSSs. Second, the regulatory changes
NHTSA proposed in the NPRM did not necessitate examination of the issue
of ``what is a driver.'' Third, NHTSA determined that revisiting the
definition of driver would best be done in a different context, perhaps
if the agency undertakes defining the ADS itself. Finally, keeping the
current definition of driver was consistent with the input NHTSA
received through the initial phase of a research project under which
the FMVSSs were reviewed to identify potential approaches for
addressing barriers.\26\
---------------------------------------------------------------------------
\26\ DOT HS 812 796, April 2020.
---------------------------------------------------------------------------
Notwithstanding NHTSA's statements above, NHTSA received several
comments suggesting amendments to the driver definition.\27\ However,
none of these comments addressed NHTSA's four areas of concern.
Accordingly, NHTSA does not amend the definition of driver in this
final rule. However, the agency will consider the input received from
comments on this rulemaking in proposing future regulatory actions.
---------------------------------------------------------------------------
\27\ For example, some commenters suggested adding ``human'' or
``conventional'' in front of driver. As the agency noted in the
preamble to the NPRM, since the ``driver'' definition clearly
indicates an ``occupant,'' specifying ``human'' is superfluous.
---------------------------------------------------------------------------
2. Newly Defined, New, Modified, and Relocated Terms
The agency proposed several changes to terms and definitions to
implement the goals of the rulemaking. These definitions were proposed
to be located or were already located in part 571.3, ``Definitions.''
Table 2, below, summarizes the NPRM's proposal for the reader.

------------------------------------------------------------------------
In proposing these definitions, NHTSA acknowledged that vehicle
designs are changing in response to technological innovation. Given
that the agency is already seeing ADS-equipped vehicles being designed
to operate in a ``driverless'' mode at all times,\28\ and understanding
that more vehicles may be designed as such in the future, the
underlying assumption behind many of the current FMVSSs that manually
operated driving controls will be present in all vehicles at all times
is no longer controlling. For vehicles designed to be solely operated
by an ADS, manually operated driving controls are logically
unnecessary.\29\ To account for this, the NPRM proposed a regulatory
scheme in which the affected standards would not assume that a vehicle
will always have a driver's seat, a steering wheel and accompanying
steering column, or just one front outboard passenger seating position.
The definition modifications proposed allows the regulatory text, to be
unambiguous related to, for example, which front seating positions are
driver or passenger designated seating positions (DSPs). Taking the
left front outboard seat as an example, this seating position may be a
passenger seating position (modified definition) because it is not a
driver's designation seating position (modified definition). It is not
a driver's (DSP) because by virtue of the definition of driver
(unmodified definition), it does not have access to a steering control
system (modified definition), which is a type of manually-operated
driving control (new definition).
---------------------------------------------------------------------------
\28\ See, e.g., Nuro R2X, discussed further below.
\29\ Note that other regulatory changes to the FMVSS not
impacted by this rulemaking (e.g., with regard to the 100-Series
FMVSSs) would likely be necessary to permit such a vehicle to be
manufactured for sale, even with the changes made by this rule
(absent an exemption to the FMVSS under 49 CFR part 555). Note also
that the Safety Act's defect provisions apply to an ADS and ADS-
equipped vehicle.
---------------------------------------------------------------------------
The NPRM proposed to accomplish this regulatory scheme by modifying
the text of the affected standards so that the front outboard passenger
seat performance requirements and test procedures would apply to all
front outboard seating positions for these vehicles. For most
standards, the NPRM proposed to accomplish this by slight textual
changes that would enable the performance requirements and test
procedures that currently apply to the right front passenger seat to be
``mirrored'' for the left side of the vehicle. If the ADS-equipped
vehicle retained a driver's seat, the NPRM proposed keeping performance
requirements and test procedures for the driver's seat, when it exists,
effectively unchanged. These proposed changes effectively turn occupant
protection requirements for the driver's seat into ``if-equipped''
requirement, meaning that when a vehicle does not have a driver's seat,
all front outboard seating positions must meet the current front
outboard passenger seat requirements. The standards to which NHTSA
proposed making this type of change were FMVSS Nos. 201, 208, 214, and
226.
Commenters generally supported NHTSA's proposed changes to the
terms and definitions. Some commenters provided suggestions and minor
modifications to the proposals. This final rule maintains the proposed
definitions and changes to terminology,
[[Page 18568]]
except for ``passenger seating position.'' We address specific comments
below.
3. Driver's Designated Seating Position, Manually Operated Driving
Controls
The NPRM proposed to define driver's designated seating position as
``a designated seating position providing immediate access to manually
operated driving controls. As used in this part [571], the terms
`driver's seating position' and `driver's seat' shall have the same
meaning as `driver's designated seating position.' ''
This definition incorporated another proposed term, manually
operated driving controls, which was defined in the NPRM as ``a system
of controls: (1) That are used by an occupant for real-time, sustained,
manual manipulation of the motor vehicle's heading (steering) and/or
speed (accelerator and brake); and (2) That are positioned such that
they can be used by an occupant, regardless of whether the occupant is
actively using the system to manipulate the vehicle's motion. The
definition of steering control system was clarified to state that it is
a type of manually operated driving control.
Comments
Many of the comments related to these definitions focused on
``unconventional'' driving controls. The Center for Auto Safety (CAS)
argued that the definition of ``driver's designated seating position''
should be written to exclude non-conventional controls such as
joysticks, computers, tablet computers or wireless remote controls, and
that reference should be made to controls that are ``permanently
attached to the vehicle in a fixed location.'' In contrast, Tesla
argued that the definition should consider situations where, for
example, ``the manual controls may be removable, or where they may
still be present, but are `locked' or rendered inoperative when the ADS
is in control of the driving task, or where the vehicle may be operated
remotely by portable steering controls within the vehicle (e.g., by
cell phones or tablets).'' Tesla stated that the definitions may not
fully consider the ``range of possibilities'' of types of controls,
such as ``buttons, joysticks, screens'' and ``should not necessarily be
determinative of whether the designated seating position should be
considered a driver's rather than a passenger's seat for purposes of
occupant protection.'' The Alliance and Toyota commented that there may
be a lack of clarity with respect to joystick type controls as to how
they would fit into the proposed definitional structure.
Agency Response
NHTSA has considered the comments but is not revising the two
proposed definitions. The agency concludes that CAS's suggested changes
would add ambiguity to the definition of the driver designated seating
position. The commenter's suggestion to add ``conventional'' to the
definition raises a question about the meaning of this term. Similarly,
we believe that making the recommended change to refer to permanently
attached controls in a fixed location may cause confusion with respect
to stowable controls that may be installed in ``dual-mode'' vehicles.
NHTSA does not agree with Tesla that it is necessary at this time
that the definition for manually operated driving controls account for
the use of tablets or cell phones to control the vehicle. The new
definition is meant to encompass traditional driving controls, not
future controls that have not yet been developed. We also note that
this rulemaking does not address joystick-type designs that are
intended to be the only manual driving control or driving controls that
have no fixed position at a particular seating location. Since this
issue raises crash avoidance and crashworthiness safety concerns that
are beyond the scope of this rulemaking action, we will not address the
matter in this final rule.\30\
---------------------------------------------------------------------------
\30\ GM focused on the plural nature of the proposed definition
to suggest that an unconventional control, such as a joystick, could
in fact be a single manually operated control (not a system of
controls) for use by a technician or for fleet management to move
the vehicle across a lot, for example. GM believed that this single
control would not be intended for use by a motorist for real-time,
sustained manual manipulation of steering or acceleration or
braking. Instead, GM envisioned this single control to be used for
the short-term, temporary activation of the vehicle for fleet
management purposes.
---------------------------------------------------------------------------
Tesla argued that only one of the terms ``steering control system''
and ``manually operated driving controls'' may be necessary, not both.
NHTSA disagrees and believes having both terms allows for a more
consistent regulatory text and less disruption from the existing text
structure. Tesla claimed that the NPRM did not address the situation
where the driving controls may still be present but are ``locked'' or
``inoperative.'' The NPRM explicitly considered inoperative controls
that remain in position.\31\ Tesla sought clarity on whether remote
operation fell into the definition of ``manually operated driving
controls.'' In response, under the definition of ``manually operated
driving controls,'' it specifies that such controls are positioned such
that they can be ``used by an occupant'' (emphasis added). Accordingly,
the definition of ``manually operated driving controls'' excludes
remote operation controls.
---------------------------------------------------------------------------
\31\ 85 FR at 17637, VI.a.vi.6.
---------------------------------------------------------------------------
The Alliance stated there is a lack of clarity with respect to
stowed manual controls. The commenter suggests the term ``stowed''
could mean a range of positions. The commenter points to the preamble
statement that research may be needed into the ``transition of
traditional manual controls in dual-mode ADS equipped vehicles.''
To be clear, issues arising from the physical act of stowing manual
controls is beyond the scope of this rulemaking. We believe the
existing standards clearly provide for occupant protection when the
controls are stowed, creating a passenger DSP. As for the meaning of
the term ``stowed,'' it is the past tense of ``stow,'' which has the
plain language meaning of ``pack or store away.'' In the 200-Series
standards, it is a term that is already used in relation to air bags,
seat belts, and sun visors. We believe that a stowed manually operated
driving control will be self-evident. Stowed controls could have
multiple potential stowed positions and configurations, but not
positioned such that they can be used by the driver.
4. Passenger Seating Position
The NPRM proposed to define ``passenger seating position'' as--any
designated seating position other than the driver's designated seating
position, except as noted below. As used in this part, the term
``passenger seat'' shall have the same meaning as ``passenger seating
position.'' As used in this part, ``passenger seating position'' means
a driver's designated seating position with stowed manual controls.
GM suggested slightly revising the last sentence in a manner that
clarifies the provision about stowed controls. NHTSA agrees in part
with GM's suggestion, and has decided in this final rule to change the
last sentence to state:
As used in this part, ``passenger seating position'' includes what
was a driver's designated seating position prior to stowing of the
manually operated driving controls.''
5. Steering Wheel to Steering Control
The NPRM proposed to change the term ``steering wheel'' to
``steering control'' in consideration of steering controls that may not
be circular, such as those shaped more like an airplane yoke control.
At every occurrence of the term ``steering wheel,'' the NPRM
substituted the term ``steering control.'' These terms were meant to be
synonymous as is evident by the use of
[[Page 18569]]
the terms in the proposed definition of ``steering control system.''
Comments
Comments were generally supportive, although some commenters raised
concerns about issues tangential to the proposal. The California State
Transportation Agency \32\ (State of California, or CalSTA) and
Securing American's Future Energy (SAFE) expressed support for the
proposal. Safe Ride News (SRN) expressed concerns related to potential
dangers for non-circular steering controls. Tesla did not comment on
the change from ``wheel'' to ``control,'' but rather was concerned that
the term ``steering control rim'' in FMVSS No. 208 implied a circular
control.

Highway Patrol and the California Department of Motor Vehicles.

The final rule will adopt the proposed change. With respect to
SRN's concerns, the change in terminology does not newly enable
manufacturers to equip vehicles with non-circular steering controls,
since such controls were never prohibited. All of the standards that
address the impact protection of steering controls remain in place. We
also disagree with Tesla's contention that the use of the term ``rim''
limits the shape of the steering control to a round object. We believe
``rim'' can reasonably be interpreted as ``outer edge.'' Thus, various
shapes are possible. We decline to make any change to the term
``steering control rim'' in this final rule.
6. Outboard Designated Seating Position
NHTSA proposed to clarify that the terms ``outboard seating
position'' and ``outboard seat'' have the same meaning as used in the
existing definition of ``outboard designated seating position.'' Our
analysis of the regulatory text of the crashworthiness FMVSSs,
determined these three terms have the same meaning. Therefore, to
clarify this point, we proposed added language specifying that
``outboard seating position'' and ``outboard seat'' have the same
meaning as ``outboard designated seating position.''
Comments
There were no adverse comments made to this proposal and the final
rule will adopt the proposed change.
7. Row and Seat Outline
The NPRM proposed to relocate the definition of ``row,'' which is
currently located in FMVSS No. 226, to Part 571.3. The term was
proposed to be used in multiple standards (FMVSS Nos. 201, 206 and
208). Moving it to part 571.3 would eliminate the need to insert a
reference to its current location.
Comments
There were no adverse comments related to moving the definition of
``row.'' However, Alliance, Zoox and GM recommended that the definition
of ``outline'' similarly be moved to part 571.3 because the definition
of ``row'' uses this term. The final rule will make this change.
8. Driver Air Bag and Driver Dummy
The NPRM proposed to define ``driver air bag,'' ``driver dummy.''
These are new definitions, but the terms already appear many times in
the FMVSSs. This is also the case for ``passenger seating position''
and ``driver's designate seating position,'' which we discussed
extensively above. However, there was previously no strong need to
define these terms. NHTSA proposed to define them now because they help
to clarify the application of the FMVSSs to ADS-equipped vehicles while
maintaining their application to traditional vehicles and minimizing
textual disruption.
Comments
There were no adverse comments made to this proposal and the final
rule will adopt the proposed change.
b. Modifying Spatial References in Test Procedures and Definitions That
Rely on the Presence of a Driver's Seat and/or Manual-Operated Driving
Controls
FMVSS Nos. 201, 206, 208, 214, 216a, 225 and 226 contain terms or
definitions that reference the driver's seat or steering controls to
provide a spatial reference for where equipment in the vehicle must be
installed, or test equipment (such as test dummies) placed in a
compliance test. The NPRM proposed various changes addressing the
situation where there is no driver's seat, a lone passenger seat, or no
steering control to provide a spatial reference frame. In some
instances, the agency proposed using the front row or the front
outboard seating position as a reference rather than the driver's seat.
In some cases, the ``left'' or ``right'' side of the vehicle was
proposed to be used rather than ``driver's side'' or ``passenger
side.''
1. Driver's Seat
The NPRM proposed using the front row, or the seating reference
point of a seat in the front row, as a spatial reference rather than
the driver's seat. Such changes were proposed for FMVSS Nos. 201, 206,
208 and 225, for buses.\33\ Most commenters were supportive of the
proposed changes.
---------------------------------------------------------------------------
\33\ The Center for Auto Safety did not comment on the specifics
of the change, but as with other bus-related issues, stated that
``it is inappropriate to consider ADS for buses within the stated
NPRM scope.'' NHTSA has responded to this issue earlier in this
preamble.
---------------------------------------------------------------------------
FMVSS No. 225, ``Child restraint anchorage systems,'' currently
defines ``shuttle bus'' as ``a bus with only one row of forward-facing
seating positions rearward of the driver's seat'' (emphasis added). The
NPRM proposed modifying the definition to state that if the bus does
not have a driver's seat, it would meet the definition of a shuttle bus
if it has only one row of forward- facing seating positions rearward of
the front row. The NPRM made no alteration for non-ADS vehicles.
Comments
The Alliance supported the change to the definition of ``shuttle
bus,'' but requested that this change be made for all vehicles, not
just vehicles without driving controls, using the same language. In
contrast, the State of California (CalSTA) commented that the
``proposed change may result in practical design and configuration
changes to shuttle buses. Further research into how these changes will
impact occupant safety on shuttle buses, if at all, is needed and
suggests that it may be premature to address at this time.'' The
Alliance further addressed provisions for rear-facing front row
seating.
NHTSA is not implementing the Alliance's suggestion to apply the
definitional change to non-ADS-equipped vehicles and is not accounting
for rear-facing front row seating. This decision is in line with the
agency's intent to focus this rulemaking narrowly to address unique
designs that might be implicated by ADSs. This rulemaking is NHTSA's
first step toward modernizing the FMVSSs to account for these new
vehicle designs. No doubt there will be other steps, as the
technologies mature, and suggestions for further amendments will be
considered at those appropriate times.
NHTSA disagrees with CalSTA since the changes will have no effect
on vehicles with driver's seats. Further, it is our expectation that
using a front row seat as a reference rather than a driver's seat will
have little to no effect on the reference point location.
For the reasons above and explained in the NPRM, this final rule
adopts the changes that refer to the front row instead of to the
driver's seat.
2. Dummy Placement in Bench Seats
Currently FMVSS Nos. 208 and 214 refer to the driver's DSP when
[[Page 18570]]
specifying where to place and position test dummies in bench seats of
vehicles in the respective compliance tests. The NPRM proposed to use
the seating reference point of outboard seats as the spatial reference
for the lateral placement of test dummies when there is no driver's
DSP.
Comments
All comments were generally in favor of using the seating reference
point of outboard seats as the spatial reference for the lateral
placement of test dummies when there is no driver's DSP.
The Center for Auto Safety (CAS) agreed with the proposed change to
FMVSS No. 208 on the use of the seating reference point as the spatial
reference for bench seats when there is no driver's seat. However, CAS
stated: ``[T]his proposal should not pertain to vehicles that include
fixed or deployable human-accessible primary or backup (potentially
deployable on demand or need) controls.'' NHTSA understands this
comment as conveying CAS's belief there should not be any reduction in
the safety of the driver as a result of this final rule--a belief with
which the agency agrees. The agency notes that the proposed regulatory
text was purposefully drafted in a manner that would not affect the
protection currently provided by vehicles with manually operated
driving controls, i.e., those with a driver's seat.
IIHS stated that the proposed method to position passenger side
dummies in the absence of a ``driver's'' seat ``seems sensible.''
However, the commenter requested that the agency ``ensure that this
change will not result in unrealistic dummy positioning for all
relevant dummy sizes before making its proposed change.'' NHTSA has
assessed how this final rule would impact dummy placement during
compliance testing and concluded that the dummy positioning procedures
are feasible for all the test dummies used in the standards, and dummy
positioning would remain realistic for all tests. The Alliance
supported the proposed language and suggested that such a method should
be used with vehicles with unconventional steering controls. This
suggestion is beyond the scope of this rulemaking but will be
considered for future actions.
3. Driver's Side and Passenger Side
FMVSS Nos. 206, 208, 216a and 226 refer to ``driver's side'' and
``passenger side'' in describing substantive requirements and
compliance test procedures. The NPRM proposed to substitute ``left
side'' for driver's side and ``right side'' for passenger side.
Comments
Some commenters were in favor of the approach NHTSA took in the
NPRM. The Alliance supported the proposed language substituting ``left
side'' for ``driver's side.'' CAS indicated that this approach is
sufficient to provide for testing under FMVSS No. 208. CalSTA supported
the proposal, stating that this approach does not result in any ``loss
in meaning.'' The commenter also agreed with similar proposed changes
in FMVSS Nos. 206, 214 and 216a.
A few commenters did not support this change. In contrast to its
comment about FMVSS No. 208, CAS stated that for FMVSS No. 214,
optional manual controls normally associated with the driver's position
could be located on the right side of the vehicle. CAS also contended
that, for FMVSS No. 226, the proposed changes to ``left front door
sill'' from ``driver's door sill'' could have implications for vehicles
that may only have doors or seating on the right side of the vehicle.
ZF stated that the question of whether this option would result in the
same performance outcome is one that needs additional study because it
is unclear to them that ``the occupant will be in the exact same
position.''
The agency is adopting its proposal to change references to the
driver's and passenger side of the vehicle to the left and right side
of the vehicle. With respect to CAS's concern about FMVSS No. 214,
whether manual controls associated with a defined driver position are
on the left or right side of the vehicle has no bearing on the
application of the standard's requirements and test procedures to a
vehicle. The standard's side impact protection requirements currently
and will continue to apply equally to the left and right sides of the
vehicle. Further, the spatial reference changes proposed for FMVSS No.
214, S10.2 were nearly identical to the changes CAS supported in FMVSS
No. 208. Regarding FMVSS No. 226, the agency is not aware of any
vehicles under 10,000 lb. GVWR without a door on the left side of the
vehicle. Regardless, placement of doors and seating on the right side
of the vehicle does not affect the application of the requirements and
test procedures of FMVSS No. 226. Finally, in response to ZF, we
believe that it is reasonable to assume at this time that occupants
would remain in the same position as currently contemplated by the
standard, and thus, the same performance outcome could be expected by
modifying the current language to ``left side'' and ``right side.''
NHTSA does not believe that additional research is necessary at this
time since this rule only changes the term used to describe the seating
position (``driver's'' seat) and not the performance requirements or
placement of the seat itself. Finally, as mentioned previously, the
scope of this rule includes conventional seating, not unconventional
seating arrangements.
4. Steering Controls as a Spatial Reference
FMVSS No. 201 S5.1.1(d) excludes from S5.1 ``areas outboard of any
point of tangency on the instrument panel of a 165 mm diameter head
form tangent to and inboard of a vertical longitudinal plane tangent to
the inboard edge of the steering wheel.'' The NPRM proposed to amend
S5.1.1(d) so that an area of the instrument panel excluded from S5.1
(the impact procedure) would no longer be excluded if the steering
control were not present, i.e., the exclusion only applies to
situations where the steering control is present.
CAS argued that the standard should apply to ADS-equipped vehicles
that include optional manual controls that are either fixed or
deployable if they are associated with a defined position. The Alliance
believed additional clarity for S5.1.1(d) is needed for dual-mode
vehicles with stowed controls, suggesting that NHTSA add the phrase
``if the steering control is present or, in the case of dual-mode
vehicles, fully deployed in manual driving mode'' to the beginning of
S5.1.1(d).
In response to CAS, the proposed amendment was intended to address
vehicles without ``steering wheels'' and where the steering control is
not present. The rule change was to ensure the protection provided by
the current passenger side of the instrument panel (right side) is
provided to the left side (former driver's side). The revised standard
will provide the same level of protection as the current standard when
a steering control system is present.
Relatedly, NHTSA declines to make the Alliance's suggested
clarification because it is unnecessary. Steering controls are defined
as a type of ``manually operated driving control.'' Manually operated
driving controls are ``positioned such that they can be used by an
occupant.'' Thus, by definition, these controls are not stowed
controls. The suggestion also raises additional questions related to
how ``dual-mode vehicles,'' ``fully deployed,'' and ``manual driving
mode'' should be defined.
c. Dual-Mode Certification
The NPRM stated that for dual-mode vehicles with the capability of
stowing driving controls, NHTSA would require
[[Page 18571]]
manufacturers to certify compliance with all applicable FMVSSs in both
modes (i.e., with the manually operated driving controls available and
with the controls stowed).\34\ When the manually operated driving
controls are available, the vehicle would be subject to the FMVSS
requirements at that DSP as applied to a driver's DSP. When they were
stowed, the vehicle would be subject to the FMVSS requirements at the
DSP as applied to a passenger seat.
---------------------------------------------------------------------------
\34\ 85 FR at 17634.
---------------------------------------------------------------------------
Comments
Many commenters supported NHTSA's approach to dual-mode vehicles.
IIHS noted that the agency's statement in the preamble \35\ that
``NHTSA expects that manufacturers will need to certify compliance in
both states (e.g., manually operated driving controls available and
stowed)'' [emphasis added] was unclear and urged NHTSA to modify the
regulatory text to ensure its expectation is met. The Automotive Safety
Council (ASC), Securing America's Future Energy (SAFE), and Uber agreed
with NHTSA's proposal to require that manufacturers certify compliance
to, and conduct validation testing in, both modes. Tesla suggested that
NHTSA add ``even more clarity regarding the applicability of the FMVSS
to such [dual-mode] vehicles. Dual-mode vehicles are likely to be some
of the first ADS-equipped vehicles on the road.'' In addition, Tesla
believes it sees a conflict in the agency statements that a seating
position is not a driver's DSP, i.e., it is a passenger DSP, if that
position is not equipped with a manually operated driving control and
the statement that a DSP remains a driver's DSP when driving controls
are in place and the ADS is engaged.
---------------------------------------------------------------------------
\35\ Id.
---------------------------------------------------------------------------
Agency Response
Among commenters addressing the issue of certification of dual-mode
vehicles, there was agreement on the need to certify in both modes. In
response to IIHS, we have reviewed the regulatory text to assure the
text is not worded in terms of ``expectations'' but is clear in terms
of requirements.\36\
---------------------------------------------------------------------------
\36\ Uber presented several hypothetical situations relating to
the Safety Act's ``make inoperative'' provision, 49 U.S.C. 30122,
which were beyond the scope of the NPRM. The Agency recommends
persons seeking a request for interpretation of NHTSA's standards or
regulations, or of the statutory provisions of the Safety Act,
submit a request for interpretation to NHTSA's Chief Counsel's
Office.
---------------------------------------------------------------------------
With respect to the Tesla comment about seeing a conflict in the
agency statements that a seating position is not a driver's DSP, NHTSA
believes these statements are not in conflict and clearly proceed from
the terms used in the regulatory text (driver, steering control system,
manually operated driving controls, driver's DSP, and passenger seating
position). For example, the definition of ``manually operated driving
controls'' makes no statement about the state of any ADS system. It
simply states, among other things, that the controls are ``positioned
such that they can be used by an occupant.'' While the steering
controls might not be used, as would be the case of a dual-mode vehicle
with the ADS engaged, the seating position where they are located and
positioned for potential use, by definition, remains the driver's DSP.
NHTSA believes that no additional regulatory text changes are
needed beyond that proposed in the NPRM to assure clarity with respect
to certification of dual-mode vehicles. NHTSA notes that if a left
front seat has both a driver configuration and a passenger
configuration, the agency may choose either configuration for
compliance testing, or test both configurations.
d. Parking Brake and Transmission Position
Many of the 200-Series FMVSSs incorporate a full vehicle crash test
or other kind of dynamic vehicle test in the standard's compliance
test. For some of these dynamic tests, a test condition applies such
that the vehicle transmission is in neutral, and/or the parking brake
applied. For vehicles without driver-accessible transmission shift
selectors or parking brake mechanisms, NHTSA may not have readily
available means to set the vehicle in neutral, activate a parking
brake, or achieve other test conditions described in the compliance
test.
NHTSA did not propose any regulatory text changes related to
interfacing with ADS-equipped vehicles on pre-test transmission and
brake status. The agency believed such changes were unnecessary for the
purposes of this notice, as the important factor for the 200-Series
FMVSSs was whether the transmission was in the proper gear and the pre-
test brake activated; the way that pre-test state was achieved was of
no consequence to performance of the crash test. It was envisioned that
manufacturers would provide the know-how for the agency to achieve the
necessary transmission and brake status when NHTSA conducts its
compliance tests. However, comments were requested on this issue.
Comments
Commenters were generally in agreement with the agency's approach.
The Center for Auto Safety (CAS) supported the agency's views on this
matter. The Alliance agreed that manufacturers could and would work
with the agency to achieve the necessary transmission and parking brake
status. Waymo stated that it ``agree[s] with the line of thinking that
the important element is whether the transmission is in the proper gear
and whether the pre-test brake is activated--not the manner in which
that state is achieved.'' \37\ GM stated it would work with NHTSA and
the agency's test labs should the need for such consultation arise.
Alternatively, Tesla believed NHTSA should ``consider updates to the
parking brake status in compliance testing where it may not reflect
real-world scenarios.''
---------------------------------------------------------------------------
\37\ Waymo stated the Agency should remain flexible in
compliance testing in general: ``[t]o implement this principle,
NHTSA could adopt policies allowing manufacturers to provide the
tools and information necessary for the agency to conduct compliance
tests in a manner befitting each manufacturer's unique automated
vehicle designs.''
---------------------------------------------------------------------------
Agency Response
NHTSA's view of how compliance tests would be conducted on vehicles
without traditional transmission shift levers or parking brake
mechanisms was supported by the commenters. The agency envisions
compliance testing will be conducted with the above framework in mind.
Tesla may be raising a point that certain test conditions may not be
necessarily relevant or appropriate for some vehicles, if, for example,
the vehicle parking brake status is not appropriate. While NHTSA agrees
that FMVSS test conditions should be relevant and appropriate for the
vehicle and for the safety need addressed by the standard at issue, the
agency is not currently aware of a situation where the parking brake
status is an inappropriate test condition or would be inappropriate for
an ADS-equipped vehicle. Consistent with the NPRM, the final rule does
not change any regulatory text related to interfacing with ADS-equipped
vehicles on pre-test transmission and brake status.
V. Occupant-Less Vehicles
Currently, the 200-Series ``vehicle'' standards apply to passenger
cars, multipurpose passenger vehicles (MPVs), trucks, buses, and school
buses. These vehicle types, as they are defined in 49 CFR 571.3, are
all, by definition, passenger-carrying vehicles, except for ``trucks.''
(A driver of a truck is considered an occupant but is not
[[Page 18572]]
considered a ``passenger.'') Occupant-less vehicles would not have
designated seating positions or any other vehicle features that aid in
the transportation of seated or standing occupants. These vehicles,
which would not even have a driver's DSP, are expected to be more
oriented to commercial movement of goods. Thus, by definition,
occupant-less vehicles cannot be categorized as a passenger car, MPV,
or bus of any kind. The definition of ``truck'' in Sec. 571.3 is the
only vehicle type definition that specifically covers vehicles designed
to carry property and not ``persons.''
Because occupant-less vehicles qualify as trucks,\38\ and since the
200-Series standards apply to trucks, occupant-less vehicles are
currently subject to the 200-Series standards even though they do not
carry occupants. In the NPRM, NHTSA tentatively determined that a
safety need did not exist to apply the existing 200-Series standards to
occupant-less vehicles. In addition, the analysis concluded that for
some 200-Series standards, the application to occupant-less trucks
could create uncertainty about certification because the requirements
are seemingly linked to the existence of specified designated seating
positions. Accordingly, with respect to trucks, NHTSA proposed to amend
the application sections of FMVSS Nos. 201, 205, 206, 207, 208, 214,
216, and 226 to apply only to trucks with DSPs.
---------------------------------------------------------------------------
\38\ Under NHTSA's self-certification framework, manufacturers
must certify their vehicles as meeting all FMVSSs applicable to the
vehicle type, and, to do so, must classify their vehicles for
purposes of determining which FMVSSs apply. NHTSA may take issue
with that classification if the agency believes the manufacturer has
misclassified the vehicle and thus failed to certify the compliance
of the vehicle appropriately with applicable FMVSSs.
---------------------------------------------------------------------------
There are some standards that are applicable to trucks that the
NPRM did not propose to amend because they only apply if a DSP were
present. One such example is FMVSS No. 202a, Head restraints.
Similarly, the agency did not propose amending the applicability of
FMVSS No. 203, Impact protection for the driver from the steering
control system, and 204, Steering control rearward displacement, to
trucks. As discussed in the NPRM, this is because those standards only
apply to vehicles with steering controls, which an occupant-less
vehicle necessarily lacks. No change was proposed for FMVSS No. 209,
Seat belt assemblies, because the standard is an equipment standard,
and no change was proposed for FMVSS No. 210, Seat belt assembly
anchorages, because that standard's requirements only apply to DSPs.
That said, NHTSA requested comment on whether any ``additional changes
are necessary or appropriate'' to accomplish the goals of the NPRM.\39\
---------------------------------------------------------------------------
\39\ 85 FR at 17625.
---------------------------------------------------------------------------
Comments
Most commenters that addressed this issue were supportive of the
proposal, but a few had reservations about how the approach could
affect crash compatibility and other safety matters. A number of
commenters focused on the applicability of FMVSS Nos. 203 and 204,
FMVSS No. 205, Glazing materials, FMVSS Nos. 212, Windshield mounting,
and 219, Windshield zone intrusion.
Most commenters believed that no safety need exists requiring
occupant protection standards for occupant-less vehicles, and that the
200-series standards were not relevant for such vehicles. The American
Trucking Associations (ATA) specifically supported changes to standards
that apply to trucks with a GVWR greater than 4,536 kg (10,000 lb.).
Uber argued that ``equipment that is designed to protect occupants in
traditional vehicles will do nothing but create unnecessary potential
safety hazards in the event of a crash or if that equipment
malfunctions.'' Nuro stated that applying occupant protection standards
to occupant-less vehicles could degrade safety by adding weight and
rigidity, which may increase ``the risk to occupants'' of other
vehicles. A number of other commenters suggested that NHTSA overlooked
several other 200-Series FMVSSs that should also be amended to exclude
occupant-less trucks from their applicability, namely FMVSS Nos. 212
and 219.
Commenters expressing concern about the proposal included the State
of California (CalSTA) regarding possible degradation to the safety of
vulnerable road users, such as pedestrians and bicyclists, if occupant-
less vehicle were excluded from FMVSS No. 205. The Automotive Safety
Council (ASC) raised the potential for crash compatibility concerns
stemming from the potential loss of energy absorption in a crash
involving an occupant-less vehicle.
Agency Response
While NHTSA believes the non-applicability of certain standards was
implicit in the proposal, the agency has considered the comments and is
adopting amendments to provide clarity. Several commenters (including
the Alliance, the Consumer Technology Association (CTA), Nuro, and,
Zoox) suggested that additional clarity is needed with respect to the
200-Series FMVSSs sections the NPRM did not propose to modify. As
discussed later below, NHTSA agrees to amend FMVSS Nos. 212 and 219 to
clarify non-applicability to occupant-less vehicles.
a. General Observations
The Center for Auto Safety argued that a truck with an optional or
deployable control system should not be excluded from FMVSS Nos. 201,
205 and 206. NHTSA would like to be clear that this subject pertains to
occupant-less vehicles that are specifically designed not to contain
occupants. NHTSA's intent is to keep the safety of occupants, including
drivers, at the forefront of this rule.
Nuro suggested three possible ways to limit the applicability of
the FMVSSs to occupant-less vehicles: (1) A blanket exclusion in
section 571.7; (2) a preamble statement; or (3) a change to all
application sections. First, a blanket change to section 571.7 or to
change ``all'' application sections would be overly broad and exceed
the scope of this notice, which focuses exclusively on the 200-series
standards. Second, a statement in the preamble would not provide
appropriate transparency and clarity. In other words, the applicability
of the standards to the vehicles in question would not be apparent from
the actual text of the standards. Thus, to assure a full and careful
consideration of the applicability of the FMVSSs to subject vehicles
and avoid unintended consequences, NHTSA has decided to evaluate each
standard and determine applicability on a standard-by-standard basis.
In some cases, no change was needed because the non-applicability of
the standard to occupant-less vehicles is indirect (e.g., by virtue of
reference to a seating position, such as for FMVSS No. 202a).
In the NPRM, NHTSA proposed to exclude occupant-less trucks from
the FMVSS occupant protection requirements, tentatively concluding
that, ``the safety need that supports the crashworthiness requirement
of FMVSS No. 208 for the protection of vehicle occupants does not exist
for occupant-less trucks.'' While this final rule affirms this
conclusion, the agency notes that the language proposed to accomplish
this exclusion applies standards to ``trucks with at least one
designated seating position.'' Commenters such as the National
Disability Rights Network, in different contexts covered in Section
VI.f of this preamble, raised the prospect of vehicles with ADS that do
not include a DSP, but accommodate people with certain physical
disabilities (e.g., through wheelchair securement mechanisms). NHTSA
notes that the
[[Page 18573]]
definition of DSP only encompasses wheelchair securement devices for a
``vehicle sold or introduced into interstate commerce for purposes that
include carrying students to and from school or related events.''
Accordingly, the proposed applicability language (referring to trucks
with at least one designated seating position) may leave ambiguity as
to whether an occupant-less truck could be permissibly outfitted with a
wheelchair securement mechanism and avoid occupant protection
requirements. While the NPRM's preamble discussion tentatively
concluded that occupant-less trucks do not present a safety need for
occupant protection requirements, the language used to exclude such
trucks was imprecise and conflicted with the tentative conclusion,
which could lead to confusion. Accordingly, the agency has decided
that, rather than amending the application sections to include ``trucks
with at least one designated seating position,'' the final rule will
specify, ``trucks designed to carry at least one person,'' which would
include occupants in wheelchair securements. We believe this will
ameliorate the problems related to referencing the DSP definition, yet
will achieve the same purpose. We note that this change should not
result in any reduction in objectivity since the definitions of
passenger car, MPV, and bus all refer to being designed to carry a
certain number of persons.
b. FMVSS No. 205, Glazing Materials
CalSTA posited that vulnerable road users, such as pedestrians and
bicyclists, might be placed at risk if occupant-less vehicles are
excluded from meeting FMVSS No. 205. The State suggested that ``[i]f
the glazing materials standard is removed, a standard providing a
commensurate level of safety for vulnerable road users should be
implemented.''
Given that one of NHTSA's guiding principles for this rulemaking
was maintaining safety levels provided by existing FMVSS, the agency
carefully considered this issue. The agency first analyzed the intended
purpose of FMVSS No. 205. The focus of the Society of Automotive
Engineers (SAE) standard, SAE J673-Automotive Safety Glasses--on which
FMVSS No. 205 is based--was to benefit the occupants of motor vehicles.
The purpose of Standard No. 205 as promulgated, and as specified today,
references vehicle occupants and makes no mention to persons struck
outside the vehicle. Nonetheless, the commenter raises the possibility
that FMVSS No. 205 has had an unintended benefit for vulnerable road
users, and the agency sought to understand any unintended consequences
of this rulemaking. Accordingly, NHTSA undertook a thorough search, but
found no crash data or research studies that could verify unintended
benefits for pedestrians, cyclists or other persons resulting from
FMVSS No. 205 glazing.
The effect of glazing in pedestrian and other road users'
collisions with motor vehicles is complex, as the crash may manifest
potential tradeoffs between various design aspects of glazing and
glazing retention. The center of the windshield, if it breaks on
impact, can be a relatively forgiving area with respect to the impact
forces/deceleration of the struck person. However, in contrast to the
middle of the windshield, the area of windshield attachment,
particularly at the A-pillars, may be relatively hazardous to a person
striking it as the pillars are stiff structural elements. For a
windshield to protect occupants, it must be adequately retained in a
crash. FMVSS No. 212 specifies windshield mounting requirements that
must be met, for the benefit of occupants, when subjected to a 48 km/h
(30 mph) barrier crash test. In order to retain the windshield, the
perimeter mounting must be sufficiently stiff. It is unclear whether or
to what extent the crashworthiness test requirements of FMVSS No. 205
contribute to, or are offset by, these forgiving yet stiff aspects of a
windshield. That is, even if the glazing is forgiving in the center
once it breaks, the windshield mounting must be stiff enough to meet
FMVSS No. 212. Any overall benefit to pedestrians and cyclists from
compliance with FMVSS No. 205 is uncertain.
It bears noting that FMVSS No. 205 is an ``if equipped'' standard.
Accordingly, the standard only requires FMVSS No. 205 glazing if
vehicles have glazing. The extent to which occupant-less vehicles would
have glazing is unknown at this time.
In its comment, Nuro argued that, if manufacturers of occupant-less
vehicles were not required to meet occupant protection requirements,
they could concentrate on protection of other road users.\40\
---------------------------------------------------------------------------
\40\ Nuro made similar arguments specific to FMVSS No. 205 in
its petition for a temporary exemption from aspects of FMVSS No.
500, which the Agency granted on February 11, 2020. Docket NHTSA-
2019-0017-0002; 85 FR 7826. FMVSS No. 500 requires low speed
vehicles to have a windshield that meets FMVSS No. 205.
---------------------------------------------------------------------------
After consideration of the information above, NHTSA has decided
that information is not available to substantiate the view that there
would be lost safety benefits to pedestrians and other road users by
excluding occupant-less vehicles from FMVSS No. 205. However, NHTSA
will monitor this issue. In view of Nuro's statement above, NHTSA
believes that the amendment adopted by this final rule may open up
avenues for potential development of more pedestrian-friendly designs
for occupant-less vehicles, though the agency is not relying on this
belief in making the decision to exclude these vehicles, as these
vehicles would not be required to make these changes.
As to more general matters, both NADA and Ford asserted that the
change to FMVSS No. 205 would not address the standard in its entirety,
and that transmissibility/visibility aspects of the standard would need
to be revisited in the future. In response, NHTSA notes that the NPRM
proposed, and this final rule adopts, revisions to FMVSS No. 205 that
apply the standard only to vehicles with occupants.
In its comment to the NPRM, Nuro stated that, just as the NPRM
proposed changes to FMVSS No. 205, conforming changes should be made to
FMVSS No. 500, Low speed vehicles, and part 565, Vehicle identification
number (VIN) requirements. Nuro sought a change to FMVSS No. 500 to
make clear that a windshield is required only if the low speed vehicle
had at least one DSP. In response, NHTSA has decided no change to the
low speed vehicle standard is necessary because FMVSS No. 500
incorporates by reference various aspects of other FMVSS. This means,
in practice, that when NHTSA makes changes to FMVSS No. 205, those
changes will automatically be incorporated into FMVSS No. 500. While
the low speed vehicle standard refers to FMVSS No. 205, the change to
the application section of FMVSS No. 205 makes clear that it does not
apply to occupant-less vehicles. Also, other aspects of FMVSS No. 500
will still apply to occupant-less vehicles, so changing FMVSS No. 500
could be confusing.
Nuro noted that part 565 requires that the VIN be visible through
``the vehicle glazing'' by an observer ``whose eye-point is located
outside the vehicle adjacent to the left windshield pillar.'' This
final rule does not amend part 565, as the matter is beyond the scope
of the NPRM. However, the agency understands the issue and will
consider addressing it in a future action.
c. Vehicle Crash Compatibility
The Automotive Safety Council (ASC) supported limiting the crash
protection requirements of FMVSS No. 208 to
[[Page 18574]]
vehicles with at least one designated seating position but argued that
measures are still needed to ensure adequate crash compatibility with
the fleet. ASC referenced ADS 2.0 statements that ``unoccupied vehicles
equipped with ADSs should provide geometric and energy absorption crash
compatibility with existing vehicles on the road.'' ASC stated that
crash compatibility ``is currently controlled to some degree by the
crash requirements of FMVSS [No.] 208. Energy absorption in the crash
by the unoccupied vehicle structure is a necessary factor in helping to
protect the occupied vehicle passengers.''
In its comment, Nuro mentioned that the preamble of the NPRM
indicated NHTSA is considering crash compatibility research and
possible rulemaking for occupant-less vehicles. Nuro stated that crash
compatibility should not be the agency's initial foray into drafting
standards for these vehicles. Nuro argued there is no reason to believe
that occupant-less vehicles should be less compatible than existing
vehicles, but that ``the opposite is true due to the lower mass and
smaller size that can be achieved for vehicles that will not carry, and
need not include protections for, humans.''
The NPRM did not include provisions related to potential vehicle-
to-vehicle crash compatibility, and this final rule continues this
approach. As stated in the NPRM, this is a complex issue that has not
yet been adequately researched and we have no evidence that vehicle-to-
vehicle crash compatibility might cause adverse safety consequences at
this time, as occupant-less vehicles do not exist in the fleet in any
significant number. However, NHTSA is engaged in research on this
subject and will also monitor on-road deployments. In addition, NHTSA
does not agree with Nuro's assertion that all future occupant-less
vehicles will necessarily be small and light and thereby a safer
collision partner because NHTSA's decision in this final rule is not
limited by weight and thus will apply to any occupant-less vehicle.
NHTSA notes that the American Trucking Associations' comment on this
subject, as previously mentioned in the Comments subsection of section
V. of this preamble, was especially supportive of changes made to
standards applying to occupant-less trucks with a GVWR greater than
4,536 kg (10,000 lb.), thus indicating that there may be occupant-less
vehicles that are much larger and heavier than Nuro's vehicles.
Further, the fact that an occupant-less vehicle does not have to
protect its own occupant does not mean that they will necessarily be
designed to protect other road users more, as it is possible that
manufacturers of occupant-less vehicles might tolerate increased risks
to other road users in the interest of protecting their own cargo.
Potential crash compatibility implications relating to occupant-less
trucks is an area of interest for the agency and warrants further
examination.
d. FMVSS Nos. 212, Windshield Mounting and 219, Windshield Zone
Intrusion
The NPRM requested comment on whether the agency had included all
relevant FMVSSs that might need changes similar to those identified in
the proposal. Many commenters suggested there was no safety need to
apply FMVSS Nos. 212 and 219 to occupant-less vehicles, as there would
be no occupants in the vehicles to protect with the countermeasures
installed to meet these Windshield mounting and Windshield zone
intrusion standards, respectively.
Agency Response
NHTSA agrees that FMVSS No. 212 and 219 should also be amended to
exclude occupant-less vehicles. It was an oversight by NHTSA not to
have included those standards in the NPRM. The NPRM for this rulemaking
action was broad and intended to include all crashworthiness (200-
Series FMVSSs) standards. In the NPRM, NHTSA discussed whether there
was a need to apply FMVSSs that serve primarily to protect vehicle
occupants to occupant-less vehicles, and whether those FMVSSs had a
continuing safety purpose for occupant-less vehicles. NHTSA requested
comment on ``whether additional changes are necessary or appropriate''
to accomplish the goals of the NPRM.\41\ This request sought the very
input that NHTSA received from commenters on FMVSS Nos. 212 and 219,
and was included in the NPRM with the intent of soliciting input on
whether the agency had included all relevant FMVSSs that might need
changes.
---------------------------------------------------------------------------
\41\ 85 FR at 17625.
---------------------------------------------------------------------------
As requested, commenters provided additional input, and the
comments received on FMVSS Nos. 212 and 219, helped NHTSA assure the
final rule would address a more complete set of relevant standards.
Given that NHTSA proposed FMVSS No. 205, Glazing materials be amended
so as not to require a windshield in an occupant-less vehicle to meet
that standard due to an absence of a safety need for the glazing,
failing to make conforming changes to FMVSS Nos. 212 and 219 would be
inconsistent with both the Agency's intended outcome and with
commenters' requests. The modifications to FMVSS Nos. 212 and 219 are
the logical outgrowth of both the discussions related to occupant-less
vehicles and the proposed regulatory text for FMVSS No. 205. Given the
absence of a safety need to apply FMVSS No. 205 to occupant-less
vehicles, there is also no safety need for occupant-less vehicles to
retain a windshield to protect against injury from penetrating objects
or ejection (FMVSS No. 212), or from windshield intrusion (FMVSS No.
219).
Accordingly, NHTSA is amending FMVSS Nos. 212 and 219 in this final
rule to exclude trucks that are not designed to carry at least one
person (occupant-less vehicles).
VI. FMVSS No. 208, Occupant Crash Protection
Making appropriate amendments to FMVSS No. 208, Occupant crash
protection is one of the most important aspects of this rulemaking. Not
only is Standard No. 208 a significant 200-Series standard, but it
includes several terms that differentiate a ``driver's'' position from
a front ``passenger's'' seating position. Thus, translating the terms
of FMVSS No. 208 to account for vehicles that do not have manually
operated steering controls, or vehicles where the manually operated
steering controls could be stowed, is central to this final rule.
The NPRM discussed proposals for: Applying FMVSS No. 208's advanced
air bag requirements to front outboard seats without manually operated
driving controls (including to seats that had been considered a
driver's seat); applying the standard's telltale requirements; applying
requirements for front outboard seats to seats that are no longer
``outboard''; and suppressing vehicle motion when a child restraint
system is sensed in a seating position with manually operated steering
controls. The NPRM also proposed amending FMVSS No. 208's bus
requirements to account for buses equipped with ADS and that lack
manually operated steering controls.
FMVSS No. 208 currently establishes crash protection requirements
that are the same for the driver's designated seating position (DSP) as
for the right front outboard seating position (commonly referred to as
the front passenger seat). The vehicle's compliance with the
requirements is assessed in a frontal crash test using adult-sized
crash test dummies.
[[Page 18575]]
To minimize air bag risks to children and small-statured adults,
however, FMVSS No. 208 also establishes ``advanced air bag''
requirements that, among other things, require the air bags at the
right front DSP to either turn off automatically in the presence of
detected young children, or deploy in a manner less likely to cause
serious or fatal injury to child occupants. Manufacturers may also
choose to combine these approaches. Vehicles that disable the passenger
air bag utilize weight sensors and/or other means of detecting the
presence of young children. To test detection capability, FMVSS No. 208
specifies that child dummies be placed in child restraint systems
(child seats) that are, in turn, placed on the passenger seat. It also
specifies ``out-of-position'' tests that are conducted with
unrestrained child dummies sitting, kneeling, standing, or lying on the
passenger seat. For manufacturers that design their passenger air bags
to deploy in a low risk manner, the standard specifies that unbelted
child dummies be placed against the instrument panel. The air bag is
then deployed. The ability of driver air bags to deploy in a low risk
manner is tested by placing the 5th percentile adult female dummy
against the steering wheel and then deploying the air bag.
In the NPRM, NHTSA tentatively concluded that the most practical
way to maintain occupant protection in ADS-equipped vehicles with no
``manually operated driving controls'' (and thus, with no driver's
seat) would be to treat any seat that does not have immediate access to
such controls as a passenger seat under the standard. Thus, all front
outboard seats in such vehicles are front outboard passenger seats and
would be required to meet FMVSS No. 208's performance requirements that
currently apply to the right front outboard passenger seat. For a seat
located in the left front outboard position, this would be done by
mirroring the test procedures and requirements from the right side.
Among other things, to maintain the level of safety currently afforded
to right front outboard passengers under FMVSS No. 208, NHTSA proposed
requiring that all front outboard ``passenger seats'' meet advanced air
bag requirements.
Comments
Commenters were generally supportive of the proposed changes to
FMVSS No. 208. Consumer Reports (CR) stated NHTSA should, ``maintain
the maximum protection under the standard in any modification. In the
case of vehicles without manual controls, this means treating each
front seat as a front outboard passenger seat and requiring all the
protections required by that designation.''
Ford supported the proposal, but with a caveat that occupant
protection requirements should not apply to an ``occasional use seat''
which is clearly marked.
Safe Ride News (SRN) supported the proposed changes but raised the
lockability requirements of S7.1.1.5a of FMVSS No. 208. These
requirements require vehicles to have a seat belt assembly with a
lockable lap belt at each seating position to facilitate the secure
attachment of child restraint systems. The standard currently excludes
the driver's seating position from lockability requirements, since, in
traditional vehicles, a child restraint would not be installed at the
driver's seat. SRN suggested NHTSA remove the exception from
lockability for seats without manually operated driving controls or
with stow-able controls in the left front seat.
Agency Response
In response, NHTSA emphasizes that under this final rule, a left
front DSP without manually operated driving controls is a passenger
seat. Similarly, a left front DSP with stow-able controls will have a
mode that makes it a passenger seat. In either case, the DSP would be
required to have a lockable seat belt. In response to Ford, we would
make clear that the requirements would apply if the seat in question
meets the definition of a DSP. Part of the DSP definition allows the
labeling of certain seats as ``not designated for occupancy while the
vehicle is in motion.'' We believe this addresses Ford's concern, but
the agency is not further expanding this provision. In the situation of
a dual-mode vehicle whose controls are always in place, i.e., the
controls cannot be stowed so the seat is always a driver's seat, the
lockability requirements would not apply, since a child restraint is
unlikely to be used at this DSP.\42\ Issues relating to children seated
in a DSP with driving controls are discussed in more detail later in
this document.
---------------------------------------------------------------------------
\42\ Further, NHTSA discourages the use of child restraints in
this driver's designated seating position. A lockable belt at that
position might imply that the DSP is appropriate for a child
restraint, and it is not.
---------------------------------------------------------------------------
CalSTA requested that NHTSA ensure that any changes in nomenclature
relative to the terms ``passenger seat'' or ``driver's seat'' would not
degrade occupant safety and requested research to confirm there is no
unintended degradation of occupant safety.
In response, NHTSA emphasizes that the left front outboard
passenger will be required to have the same protection as the right
front outboard passenger DSP, which for adults are the same
requirements that would apply to a driver's seat. The current occupant
protection requirements have been in place for almost 30 years. The
immense technical data and information NHTSA and the occupant safety
community have acquired over this period indicate there is no
difference in the FMVSS No. 208 protection afforded adult occupants by
the left or right front seating position. The data and other
information on advanced air bag safety protections also indicate there
are no technical reasons why the protections provided by a seat in the
right front outboard seating position could not be mirrored by a
passenger seat on the left side. Additional research is not necessary
to verify that protections afforded to one seating position would be
sufficient for the other seating position, as identical designs could
be applied to the opposite sides of a vehicle.
This final rule adopts the proposal's provisions relating to the
left front seat when that DSP meets the definition of a passenger
seating position. The final rule makes minor clarifying changes to the
regulatory text in response to comments, which are discussed below.
This final rule adopts the provisions of the NPRM that relate to
advanced air bag requirements, telltale requirements (indicating air
bag suppression for the left front outboard seating position), and
other requirements, except as discussed below.
a. Advanced Air Bags
As discussed in the proposal, applying advanced air bag
requirements to all front outboard seating positions maintains the
current levels of safety for ADS-equipped vehicles without manually
operated driving controls. Applying the requirements meets the need for
safety because an occupant will receive the same crash protection
whether they choose to sit in the left or right front outboard seat. In
addition, an important benefit of advanced air bags over conventional
air bags is the protection of out-of-position occupants, particularly
children. In a traditional vehicle, the occupant in the driver's seat
is typically an adult. In contrast, occupants of the left front
outboard passenger seats in an ADS-equipped vehicle without manually
operated driving controls could possibly be children, as there would be
no driving control mechanism at any position that may deter occupancy
of the seating position by a child. NHTSA tentatively
[[Page 18576]]
concluded in the NPRM that the most straightforward way to protect
children against air bag risks would be to require that any front
outboard seat that could potentially be occupied by a child (i.e., a
passenger seat) must meet the current advanced air bag requirements.
This final rule adopts the provisions of the NPRM that relate to the
protection of the left front seat occupant when that DSP meets this
final rule's definition of a passenger seating position.
With regard to the static suppression requirement of FMVSS No. 208
S22.2 for the 3-year-old child dummy, GM and the Alliance asked that
the regulatory text ``clearly specify that suppression is tested only
for the seating position where the child dummy is placed.'' NHTSA
agrees the clarification is warranted and has added language to S22.1
to make clear that the relevant air bag that is to be suppressed is the
air bag associated with the designated seating position being assessed.
NHTSA has made similar clarifications to the text of FMVSS No. 208
regarding tests with the 12-month-old (S20.2) and 6-year-old (S24.2)
child dummies.
NADA commented that air bag switch installation should apply, ``to
the extent applicable and appropriate.'' However, air bag on/off switch
requirements comprise a topic beyond the scope of this rulemaking.
Accordingly, NHTSA is not considering this suggestion in this
rulemaking.
b. Telltales
FMVSS No. 208 currently requires that vehicles display a telltale,
visible to the front row occupants, which indicates whether the front
outboard passenger seat air bag is suppressed. Given that this
rulemaking may result in multiple front outboard passenger seats, NHTSA
proposed amending this requirement to specify that a separate telltale
would be required for each outboard front passenger seat based upon the
belief that doing so would maintain the current level of safety
provided by the standard. The NPRM proposed that the current telltale's
substantive performance criteria would remain the same to provide
occupants with the same level of information about the status of each
pertinent air bag as provided by the current standard. Because the left
front seat without manually operated controls would be a passenger
seat, the NPRM proposed to require an additional telltale.
Commenters had differing views on this issue. The Alliance and GM
requested that NHTSA consider a single telltale unit for both front
outboard seating positions, so long as that telltale is visible from
each seating position. The Center for Auto Safety (CAS) stated, ``it is
important for occupants to verify the operational capability of safety-
critical equipment in vehicles they occupy, including telltales for
suppression-based advanced air bag systems.'' Safe Ride News (SRN)
supported requiring seat-specific telltales. Various commenters had
concerns or suggestions that are addressed below.
Agency Response
The final rule adopts the provisions of the NPRM, with a few
modifications in response to comments received. The Alliance and GM
requested allowing a single telltale for both front outboard seating
positions. It is NHTSA's position that, while a single telltale unit
that distinguishes both indicators would be acceptable, a single light
indicating the suppression status of both air bag systems, but not
distinguishing their individual state of suppression would not.
Separate suppression telltales clarify which associated seating
position is suppressed, allowing the corresponding passenger to respond
to the information with appropriate action. Separate suppression
telltales verify to the caregiver of children placed in seating
positions that the corresponding air bag is suppressed and allow other
users to determine whether the air bag corresponding to their seating
position is properly functioning. Thus, this final rule requires the
telltale to be clearly recognizable to a driver and any front outboard
passenger with which seat each telltale is associated.
IIHS argued that the proposal's use of ``any'' in reference to
seating position requirements from which telltales required by FMVSS
Nos. 226 (S4.2.2) and 208 (S19.2.2(d)) must be visible, is ambiguous,
and suggested that the final rule use the term ``all.'' The IIHS
comment seems to interpret the proposal as seeking to require that the
suppression telltale be visible from any DSP in the vehicle. This is
incorrect. The proposal restricted visibility to the front outboard
seats for the FMVSS No. 208 telltale. Accordingly, the final rule will
retain the word ``any'' in FMVSS No. 208 S19.2.2(d). Comments specific
to the FMVSS No. 226 telltale are addressed later in this document.
Safe Ride News commented that the location should be ``on the dash
in easy-to-see, logical juxtaposition to the seat for which it
applies.'' On the other hand, the Automotive Safety Council (ASC)
believed that the location of the telltale should be chosen to provide
information regardless of where an adult may be seated in the vehicle.
As noted above in our response to IIHS, we decline to implement the
suggestion that the suppression telltales be visible from all seating
positions. While expanding telltale visibility requirements generally
is worthy of discussion, it is beyond the scope of this rulemaking. As
stated elsewhere in the proposal and this document, NHTSA plans to
issue a separate notice that will focus on telltales and warnings for
ADS-equipped vehicles. In the interim, this final rule will establish
requirements that will allow front seat occupants in vehicles without
manual controls to determine whether either outboard front seating
position has a suppressed air bag.
Disability rights advocacy groups (National Disability Rights
Network (NDRN), Disability Rights Education Fund (DREDF), and the
Consortium for Citizens with Disabilities (CCD)) requested that NHTSA
consider adding audible or haptic alerts to the visual alerts for
suppression telltale information.\43\ NHTSA is not aware of any
previous implementation of haptic non-driving related warnings. More
information and research may be necessary to implement types of layered
alerts to ensure that vehicle occupants receive clear information that
would not confuse or conflict with other information. NHTSA is aware
that audible warnings have been implemented and there may be merit to
such an implementation. However, as we reasoned above, we decline to
implement audible warnings now because they require a larger discussion
and more input on how best to achieve the goals of providing
information, while also avoiding confusing vehicle occupants. That
discussion is beyond the scope of this rulemaking but could be explored
in the forthcoming notice on telltales. The agency notes, though, that
nothing in this rule would prohibit audible or haptic alerts when used
to complement the required visual alert.
---------------------------------------------------------------------------
\43\ These groups also suggested the Agency look to information
presented at the November 2019 meeting, NHTSA Research Public
Meeting, [www.regulations.com NHTSA-2019-0083-0007]. Among many
topics, this meeting covered research on vulnerable and disabled
road users. The Agency presented a brief summary of a research
program entitled ``Vulnerable and Disabled Road Users:
Considerations Inside and Outside the Vehicle.'' The research
program is ongoing and scheduled for completion in 2022.
---------------------------------------------------------------------------
IEE expressed concern that ADS-equipped vehicles might have no seat
belt warning system as required by FMVSS No. 208, S7.3 because they may
have no driver's DSP. IEE recommended that NHTSA require a seat belt
reminder system in ADS vehicles that provides audio-visual warnings for
unbelted occupants. The requested revisions are
[[Page 18577]]
beyond the scope of the present rulemaking. NHTSA may consider this
issue in future agency work related to telltales and indicators for
ADS-equipped vehicles.
c. Front Outboard Versus Center or Inboard Seating Position
An ``outboard seating position'' is defined in 49 CFR 571.3 as ``a
designated seating position where a longitudinal vertical plane tangent
to the outboard side of the seat cushion is less than 12 inches from
the innermost point on the inside surface of the vehicle at a height
between the design H-point and the shoulder reference point (as shown
in fig. 1 of Federal Motor Vehicle Safety Standard No. 210) and
longitudinally between the front and rear edges of the seat cushion.''
FMVSS No. 208 requires, for most light vehicles (GVWR less than 4,536
kg (10,000 lb.)), each ``outboard designated seating position,''
including the driver's seat, to have a lap/shoulder (Type 2) seat belt
assembly that conforms to FMVSS No. 209, Seat belt assemblies.
Moreover, the subset of light vehicles that have a GVWR of less than
3,855 kg (8,500 lb.) and unloaded weight of 2,495 kg (5,500 lb.) are
statutorily required \44\ to have frontal air bag protection at the
driver's and right front DSPs, which are evaluated by FMVSS No. 208's
frontal barrier crash tests. Under FMVSS No. 208, any center seating
positions in these light vehicles can be equipped with only a lap belt.
---------------------------------------------------------------------------
\44\ Intermodal Surface Transportation Efficiency Act of 1991,
Public Law 102-240, 2508 (Dec. 18, 1991).
---------------------------------------------------------------------------
In the NPRM, NHTSA acknowledged that future vehicle designs might
not have two front outboard seating positions. The agency sought to
amend FMVSS No. 208 to be inclusive of and account for ADS-equipped
vehicles (particularly those without driving controls) that might not
have a front left outboard DSP or, for that matter, any outboard DSP,
as those terms are defined in NHTSA's regulations. NHTSA envisioned
that one or both of the outboard seating positions on a current vehicle
could be moved toward the center of the vehicle and thus fall outside
of the outboard seating position definition. NHTSA sought to amend
FMVSS No. 208 to provide occupants of an ADS-equipped vehicle with
fewer than two front outboard seating positions no degradation in the
crash protection now required by the standard for vehicles that are not
ADS vehicles. The agency requested comment on including in the final
rule air bag (including out-of-position occupant protection) and lap/
shoulder (Type 2) seat belt protection to these inboard seating
positions if outboard positions were removed. We also requested comment
on the implications of such designs upon the statutory obligation for
frontal air bags.
Comments
Several entities, primarily consumer advocacy groups, commented in
favor of providing Type 2 belts and air bags at all inboard seats. The
Center for Auto Safety (CAS) stated that both lap/shoulder belts and
air bags should be required for inboard seating positions in ADS-
equipped vehicles. Safe Ride News (SRN) commented that the front center
seating position in ADS and non-ADS vehicles ``should no longer be
allowed to be equipped with Type 1 (lap-only) belts, which are far less
protective than Type 2 belts.'' SRN noted that it believes this request
is even more important since it expects it will be more likely that
children would be seated in the front row in ADS-equipped vehicles,
though did not provide any support for this expectation. IEE requested
FMVSS No. 208 require advanced air bags at inboard seats. The
Automotive Safety Council (ASC) stated that ``automated vehicles may
have increased usage/presence of a center seating position, possibly
without accompanying outboard seating positions.'' ASC argued that ``it
is reasonable'' to apply the out-of-position advanced air bag
requirements for all front designated seating positions. IIHS stated
that all designated seating positions should receive ``the same level
of crash protection'' in ADS-equipped vehicles, and that front row
center positions should be required to have Type 2 belts and air bag
protection.
Some commenters focused on the protection that should be afforded a
single center seat. The Alliance commented that ``[w]here there is only
a single forward-facing front row center seat (and no other front row
seating positions), current levels of FMVSS 208 crash performance,
including advanced air bag performance criteria, if applicable, should
be required for that position.'' However, the commenter also stated,
``there should not be a specific air bag installment requirement to
meet this crash performance.'' Ford expressed support for the final
rule ``to apply the current performance requirements for the passenger
seat called out in FMVSS [No.] 208, to both outboard positions when
there are no controls, or to the center seat when the outboard seating
positions are absent.'' \45\ GM also suggested that ``where there is
only a single forward-facing front row center seat, GM supports
applying current right front outboard passenger side FMVSS [No.] 208
crash performance requirements.'' ZF argued that if a single seat is
installed in the front of the vehicle without driving controls, that
occupant should be protected in the same manner as an outboard
passenger occupant, including seat belts, and an air bag. The National
Automobile Dealers Association (NADA) stated that ``any vehicle (ADS-
equipped or otherwise) with a single forward-facing front row center
seat should be subject to FMVSS [No.] 208 crash performance
requirements, including applicable advanced air bag performance
criteria.''
---------------------------------------------------------------------------
\45\ To clarify, Ford suggested these occupant protection
requirements should not apply to an ``occasional use seat'' which is
clearly marked. This comment was addressed previously in this
preamble.
---------------------------------------------------------------------------
Several commenters requested additional research on the issue.
Waymo stated ``considerable technical research and a new proposed
rule'' may be needed to address the protection that should be offered
to inboard front seats when there are no outboard seats. Waymo also
stated that ``[i]f such seating arrangements are in fact likely,''
Waymo prefers that NHTSA finalize this rule and deal with this
``novel'' issue in a separate rulemaking. Tesla urged NHTSA first to
conduct research on the appropriateness and type of equipment
(especially for out-of-position) that is needed to protect an occupant
in the non-outboard seating position, including, e.g., where the center
seat could serve as both an armrest for outboard occupants and a
foldable seat. CalSTA recommended further testing to ensure there is
not an unintended compromise to occupant safety if implemented.
Agency Response
In deciding how to respond in this final rule to the comments
expressed on this topic, NHTSA considered its guiding principles for
this rulemaking.\46\ One principle is for NHTSA to take every effort to
maintain the level of crashworthiness performance in ADS-equipped
vehicles without traditional manual controls currently required for
vehicles without ADS functionality. Another is for NHTSA to adapt
existing FMVSS requirements to ADS-equipped vehicles in a way that does
not change requirements for non-ADS vehicles. In addition, NHTSA seeks
to modify the FMVSSs in a manner that is more
[[Page 18578]]
attentive to the innovative interior designs that are expected to
accompany ADS-equipped vehicles.
---------------------------------------------------------------------------
\46\ These are set forth in the Executive Summary at the
beginning of this preamble.
---------------------------------------------------------------------------
Applying these principles, NHTSA's decisions focus on protecting
the public and minimizing any potential loss in crash protection
provided by vehicles if outboard seats are removed in favor of inboard
seats. Further, NHTSA primarily seeks to retain the protections from
existing requirements in a manner that allows for innovators to develop
certain alternative configurations that can accommodate vehicles with
ADS. NHTSA has also made decisions considering the practicability of
meeting requirements and the reasonableness of applying current FMVSS
No. 208 requirements to inboard seat designs.
Taking these principles into account, NHTSA notes that passenger
cars, multipurpose passenger vehicles, trucks and buses with a GVWR of
less than 3,855 kg (8,500 lb.) and unloaded weight of 2,495 kg (5,500
lb.) are already required to have advanced air bag systems installed at
the front outboard seating positions. Accordingly, the agency has
decided to apply the FMVSS No. 208 protections now applying to the
outboard seating positions to inboard seating positions, to the extent
technically feasible. This final rule adopts a balanced path between
the commenters that desire air bag and lap/shoulder belt protection at
all inboard seats and those that believe such protection should be
required only at a single inboard seat.
To accomplish this, this final rule will implement the following
(see Figure 1). First, FMVSS No. 208 currently protects two designated
seating positions in the front row of seats with a ``full'' suite of
occupant protection countermeasures: Type 2 (lap/shoulder belt system),
and an advanced air bag system. Those protected seats are currently the
outboard seating positions. To maintain FMVSS No. 208's protection of
two seating positions in the front row--to the extent technically
feasible--this final rule continues protecting two designated seating
positions in the front row with the full suite of protective
countermeasures (Type 2 belt and advanced air bag). Thus, where there
is a single inboard seat and one or no outboard seats, the single
inboard seat would be required to have lap/shoulder seat belts and
advanced air bag protection in that single front row inboard seat, and
any one remaining outboard seat will continue to offer the same
protection as it does currently in vehicles with driving controls (the
full suite of crash protection).
Second, NHTSA considered a front row with multiple inboard seats
and one or no outboard seats. As discussed above, this final rule seeks
to maintain protecting two designated seating positions in the front
row with the full suite of protective countermeasures (Type 2 belt and
advanced air bag). Thus, for this situation, the protection required by
the vehicle depends on whether there is a remaining single outboard
seat or not. If there is a remaining single outboard seat, that
outboard DSP will be required to provide the full suite of protection
(lap/shoulder seat belts and advanced air bag protection), and one of
the inboard seats will be required to offer the same full suite. The
manufacturer will have the discretion to determine which of the inboard
seats will offer this protection. The other inboard seat (if any) would
only require a lap belt (a lap/shoulder belt may be provided at the
manufacturers' choice), as this is the requirement now specified for an
inboard first row seat under FMVSS No. 208. Thus, the protection
offered by this configuration is essentially the same as vehicles with
driving controls and three front seats (i.e., two DSPs with full suite
of protection and one with lap belt protection).
In the second case, it is possible there is no outboard seat, but
multiple inboard seats. For this situation, only a single inboard seat
will be required to provide the full suite of protection (lap/shoulder
seat belts and advanced air bag protection). The other inboard seat
will only be required to offer a lap/shoulder belt. While the agency
would like to require the full suite of protections for two DSPs in
accordance with our principles above, we are not requiring a full suite
of protection for the second DSP because of potential safety risks
posed by air bags operating in close proximity to each other (e.g.,
interaction between the two air bags or between occupants in close
proximity when reacting to the air bags), as in the case of two inboard
side-by-side seats. Commenters Waymo, Tesla and CalSTA suggested that
additional research may be needed to discern if there are any
unintended consequences related to more than one inboard seat with
frontal air bag protection being in close proximity. NHTSA agrees with
these commenters and plans to conduct research to determine the minimum
lateral distance between the seats where air bag protection could be
provided to both DSPs. The agency does not know how commonly such
vehicle configurations will be produced and will seek additional
information on this issue before pursuing a regulatory mandate.
To be clear, NHTSA does not believe any such research is needed for
the situation where a single inboard passenger seat has frontal air bag
protection, even with another non-air bag protected seat in close
proximity. Neither does NHTSA believe that a separate rulemaking is
necessary to provide FMVSS No. 208 protections to a single inboard
seating position. This is because the technology required in that
situation is used by the millions in vehicles today, with decades of
experience (currently there are front outboard seating positions with
Type 2 belts and air bags right next to a center seating position with
a lap belt or Type 2 belt). Vehicle manufacturers may need to address
the specifics of the vehicle interior geometry and crash pulse to
develop an appropriate design, but the agency has no reason to believe
that providing a full suite of protection to a single inboard seat will
be more challenging than for an outboard seat.
The above specified regulatory changes have been implemented in
S4.1.5.6 and S4.5.6.4 of FMVSS No. 208. The regulatory approach taken
in these sections was to point to the test procedures as specified for
front outboard designated seating positions and apply them to the
inboard seats, as appropriate. We believe that, except as noted below
for bench seat positioning, the procedures as written can be performed
on inboard seats, without adaptations. The agency has made minor edits
to S16.2.10 and S16.2.10.3 to clarify positioning of inboard seats, in
the case where seat positioning cannot be independently controlled.
Finally, NHTSA carefully considered the Alliance comment on inboard
seat protection suggesting that current levels of crash performance be
provided, including advanced air bag performance criteria, but without
a specific air bag installation requirement. We interpreted this to
mean that any stipulation for ``inflatable restraint'' should be
removed from S4.1.5.6.3, with all other provisions remaining. The
agency is declining to make this change at this time. The text is
clearer with the reference to ``inflatable restraint'' than without it.
Also, there are questions of scope related to this request and NHTSA
would like to consider further comments on the suggestion.

d. Suppression of Vehicle Motion When a Child Is Detected in the
Driver's Seat
Because some ADS-equipped vehicles may be designed with a driver's
seat (i.e., a seat with immediate access to manually operated driving
controls), NHTSA explored the possibility that a child may be seated in
a driver's seat during ADS operation. As stated previously, NHTSA
believes that children should not occupy the driver's position when the
vehicle is operating in ADS mode and steering controls are present.
Such a situation might occur when a caregiver places a child in this
seat or when an older child places themselves in this position. This is
a concern because a driver's seat is not a passenger seat, a driver's
seat would not be subject to advanced air bag requirements protecting
out-of-position children from air bag risks. In addition, the crash
protection in the driver's seat is not tailored to a child. NHTSA was
concerned about this possibility and proposed that ADS-equipped
vehicles that have manually operated driving controls must render the
vehicle incapable of motion if a child is detected in the driver's
seat. The agency proposed that the ADS vehicle would be tested for
compliance with this ``motion suppression'' requirement using the 12-
month-old, 3-year-old and 6-year-old child test dummies currently used
for out-of-position testing in the standard.
Many comments discussed this aspect of the proposal, with a variety
of approaches. In general, commenters on this topic acknowledged that a
potential problem exists that should be addressed but differed in their
approach to a solution and beliefs about the readiness for a regulatory
solution. Many non-industry commenters agreed with the proposal, as did
some suppliers and an ADS developer. However, a couple commenters
raised concerns about the proposal. Additional details on these
comments are provided below.
Many commenters, including Consumer Reports, Safe Ride News (SRN),
Johns Hopkins University, IIHS, IEE, the Automotive Safety Council
(ASC), and the Center for Auto Safety (CAS) supported NHTSA's proposal
to require motion suppression if a child were detected in the driver's
seat of an ADS-equipped vehicle. CAS stated that the vehicle should be
immovable if any child were detected in the driver's seat
[[Page 18580]]
while the vehicle is stationary and should revert to a safe stop if a
child is detected in the driver's seat while underway. CAS and SRN
recommended that the suppression test be performed with a Hybrid III
10-year-old child test dummy. Johns Hopkins University requested
research on the behavior of occupants of various ages and sizes when
seated as passengers in the driver position to ensure that they will
receive the same protections.
In contrast, a number of commenters expressed concerns about the
proposal. The NDRN explained that ``child protections that limit the
vehicle's motion would have the unintended consequence of prohibiting
access and discriminating against adult drivers of short stature.''
This concern was also expressed by DREDF and CCS. NDRN stated that a
vehicle's sensors would not know the difference between a child and an
adult driver whose weight and height may be similar. The Alliance
stated that ``whenever a child can be placed in front of an air bag
when the vehicle is in motion the appropriate advanced air bag
requirements should apply at that seating position.'' That said, the
Alliance argued that ``the issue of vehicle motion suppression does not
fall within the category of a simple technical translation of current
FMVSS [No.] 208 requirements,'' but is an ``operational topic'' that
NHTSA can and should address ``on a separate track.'' Waymo stated that
it recognized the importance of protecting small children from air bag
risks but had concerns about the proposed vehicle motion suppression
approach. Waymo stated, ``it may be technically feasible to address
that risk by requiring the same advanced air bag protections in the
driver's seat of dual-mode vehicles as those that are currently
required in the right front outboard passenger seat. In fact, there may
be other technical solutions that would obviate the need for the NPRM's
proposal. . . . Waymo is confident that auto manufacturers can develop
sound technical ways to address this issue.''
Ford stated that it ``appreciates NHTSA's safety concerns for child
seats mounted in the driver seat of a `Dual mode' AV when the ADS is
active,'' but sought an additional compliance option beyond motion
suppression. Ford identified two risk categories for children in the
driver's seat: Crash protections; and unintentional takeover of the
driving task. Ford stated that the crash protection risk could be
addressed by ``[e]nsur[ing] the same level of crash protection for
children of various ages in the driver seat position as provided today
in the passenger outboard seating position,'' while the risk of
unintentional take-over could be addressed ``by suppressing manual
requests to the steering control in ADS mode when a child is detected
in the driver seat.'' GM asserted that motion suppression for dual-mode
ADS-vehicles should not be the focus of the NPRM, but that it ``is
aligned with the need to address child occupant safety in dual-mode
ADS-equipped vehicles and would support applying existing air bag
suppression requirements (and/or low risk deployment) to accomplish
this.''
Agency Response
NHTSA has decided not to adopt the proposal for motion suppression
of the vehicle in this final rule. Additional information is needed to
gain a fuller understanding of potential unintended consequences of the
proposal, the potential safety problem related to interaction with
driving controls, and available regulatory solutions before a final
decision can be made. While the agency believes that FMVSS No. 208's
air bag suppression test procedure could form the basis of a test
procedure for a vehicle motion suppression regulatory option, such as
that proposed in the NPRM,\47\ additional work is necessary to address
problems relating to a vehicle's sensors distinguishing between a child
and an adult driver similar in size to a child.\48\
---------------------------------------------------------------------------
\47\ Many commenters were under the mistaken impression that the
NPRM only proposed that the 12-month-old CRABI dummy was to be used
to assure vehicle motion suppression. To clarify, the NPRM proposed
to use the 12-month-old, the 3-year-old, and the 6-year-old child
dummies in the proposed procedure.
\48\ At this time, NHTSA is not aware of any production-ready
technical solution for occupant detection that would be able to
discriminate between a 6-year-old or younger child and an adult of a
similar or smaller size, and does not know of a test procedure that
could be used to test a system's ability to do so.
---------------------------------------------------------------------------
While several commenters suggested potential alternative regulatory
solutions, they are outside of the scope of this rulemaking, require
research to determine their technical feasibility, or require further
analysis to determine whether they would be consistent with the
requirements of the Safety Act. Some suggested requiring the same
advanced air bag protections in the driver's seat of dual-mode vehicles
as those that are currently required in the right front outboard
passenger seat. That approach does not address concerns with the effect
the manually operated driving controls themselves could have on the
children's crash protection. For instance, would an infant in a rear-
facing child restraint in a seating position with a steering control
system be adequately protected when the air bag is suppressed? Would a
child in a forward-facing child restraint in a seating position with a
steering control system be adequately protected when the air bag is
suppressed or in a low risk deployment state? How should test
procedures be developed to assess the crash protection provided to
children in a driver's seating positions relative to the passenger
position? While caregivers are taught to transport children in rear
seating positions, to what extent would children be transported in ADS
vehicles in seating positions that have manually operated driving
controls? To finalize a rule in this area, the agency would like to
answer these questions, and those answers require additional research.
NHTSA plans to initiate research into the possibility of
alternative regulatory options that allow vehicle motion, but that also
address the risk of children in a driver's seat. The agency is
interested in the development of an analogous procedure to the child
passenger low risk deployment tests, but for seats with manual
controls. A test could be developed that assesses the injury risk from
a deploying air bag on an out of position child. Another aspect of this
research may attempt to discern whether the presence of the steering
control (even with a suppressed or low risk deployment air bag) results
in an unreasonable safety risk to an in-position child in the driver's
seat compared to a child in a passenger seat.
While NHTSA has decided not to proceed with adopting the proposed
requirement for vehicle motion suppression, we disagree with the
assertion that this proposal was not appropriate for the rulemaking.
While the rulemaking focused on translating the current FMVSS No. 208
requirements to account for ADS vehicles, the agency appropriately
discerned what it believed to be a crash protection issue and a risk
case that is a consequence of the vehicle design changes that may
accompany vehicles equipped with ADS technology. After review of the
comments, NHTSA has concluded that more information is needed to
identify and understand the nature and extent of the potential safety
problem and available regulatory alternatives.\49\ The agency
anticipates revisiting this issue as more is learned from research and
as the technologies develop.
---------------------------------------------------------------------------
\49\ This decision accords with E.O. 12866, Regulatory Planning
and Review, Section 1.

e. Belts in Buses
FMVSS No. 208 establishes seat belt requirements for ``medium-
sized'' buses
[[Page 18581]]
(with a GVWR between 4,536 kg (10,000 lb) and 11,793 kg (26,000 lb))
and ``large'' buses (GVWR greater than 11,793 kg (26,000 lb)). For
school buses, the driver's seating position is required to have a Type
2 seat belt. For the other buses, the driver's seating position is
required to have a Type 1 or 2 seat belt (alternatively, a vehicle may
meet a crash test option in FMVSS No. 208, depending on the vehicle).
The NPRM sought comment on how the belt requirement should apply to an
ADS bus that does not have a driver's seat. Comments were requested on
whether the standard should require a seat belt for all front seats,
for just the left front outboard seating position, or for only at least
one front passenger seat. NHTSA proposed that all front passenger seats
should be protected with the same level of protection that would apply
to the driver of a non-ADS vehicle. Our stated rationale was that there
is likely a similar safety risk in all front row seats of these medium
and large buses and that the prediction of where an individual might
sit in the front row is likely to change in ADS-equipped vehicles. The
NPRM discussed concerns with arbitrarily determining which front row
occupant receives the protection of a seat belt or allowing
manufacturers to make that determination. (See proposed amendments to
FMVSS No. 208 S4.4.4.1.2, S4.4.4.2 and S4.4.5.3.)
Many commenters (including the Alliance, Hyundai, Safe Kids, CAS,
CalSTA, the Automotive Safety Council (ASC), Safe Ride News (SRN))
supported NHTSA's proposal. ASC also believed the proposed text should
apply regardless of whether they are ADS or non-ADS vehicles and
suggested there should be a seat belt warning for each position. SRN
believed that the occupant protection formerly provided for an adult
driver should be available for a supervisory adult or adults in school
buses with ADS.
Agency Response
The final rule adopts the proposed changes to the seat belts
required for the front seats of medium sized buses (GVWR or more than
4,536 kg (10,000 lb), but not greater than 11,793 (26,000 lb)) without
driver's DSPs, but will not proceed with the changes for large school
buses (GVWR of more than 4,536 kg (10,000 lb)).\50\ We will separate
this discussion into large school buses and medium size non-school
buses.
---------------------------------------------------------------------------
\50\ FMVSS No. 222, ``School bus passenger seating and crash
protection,'' considers buses with a GVWR greater than 4,536 kg
(10,000 lb.) as large school buses (S5(a)).
---------------------------------------------------------------------------
For large school buses described above, we have decided that more
examination is necessary before finalizing a requirement. The FMVSS No.
222 compartmentalization requirements for passenger seats remain in
place. We believe any changes to the compartmentalization requirement
of FMVSS No. 222 for front row seats of novel ADS-equipped school buses
require a more fulsome discussion before moving forward.
NHTSA is finalizing its proposal for medium size buses, other than
school buses, to require the same occupant protection at the front seat
of an ADS as would currently be met by the driver's seat. However,
modifying existing FMVSSs to require seat belt warnings for each bus
seat would be outside the scope of this rulemaking.
CAS submitted that school buses should not be included in this
rulemaking due to the unique role a human driver has in interacting
with and overseeing the student occupants. The commenter is concerned
about a rulemaking that has the effect of encouraging the development
of school buses with ADS, because school buses rely on the human driver
for more tasks such as ``safety during ingress and egress, for
discipline while underway, and for emergency evacuation in a variety of
life-endangering situations.'' They argue that ``any proposed rule on
occupant protection for driverless school buses should be withdrawn
unless and until all safety aspects of such operation are considered.''
In response, NHTSA believes the CAS request that this rulemaking
action exclude any changes that affect school buses is unwarranted. The
final rule simply updates terms in the standards to make them
technology-neutral to account for ADS-equipped vehicles, particularly
those without manual controls, while providing the same amount of
occupant protection. NHTSA notes that Federal law does not prohibit
installation of an ADS on a school bus, currently. CAS did not provide
any particularized safety issues within the scope of this rulemaking
that would justify NHTSA's not proceeding with amending the school bus
FMVSSs. NHTSA does not regulate the use or operation of school buses,
so even with this final rule, States or local school districts can
continue to purchase only non-ADS school buses if they wish to do so,
and existing operational and supervisory requirements on a State, local
or school district level could apply as well.
f. Corrections to FMVSS No. 208 Regulatory Text
NHTSA realized from some of the comments that editorial corrections
should be made to some of the provisions of FMVSS No. 208.
Zoox believed that a change in S19.2.2(e) is needed for consistency
throughout the regulatory text. NHTSA agrees with Zoox that S19.2.2(e)
should be changed such that the reference to the ``right front
passenger'' is changed to ``any front outboard passenger.'' The agency
believes this is consistent with changes made throughout the FMVSSs to
address the situation where there may be more than one front outboard
passenger.
FMVSS No. 208, S4.2 defines, for use in that section, the term
``vehicles manufactured for operation by persons with disabilities.''
The purpose of this definition was to allow an exception to the type of
seat belt required in the driver's seating position in S4.2.1.2(b),
which is a superseded section of FMVSS No. 208. The National Disability
Rights Network (NDRN) commented that ``[l]anguage needs to be added to
these provisions that takes into consideration the potential for
wheelchair accessible ADS-equipped vehicles without manual controls or
a driver's seat and reference to a front left outboard seat.''
In response, S4.2.1.2(b) has been superseded and the term
``vehicles manufactured for operation by persons with disabilities'' is
no longer used anywhere in active portions of FMVSS No. 208, aside from
the definition that is provided in S4.2. NHTSA interprets NDRN's
comment as requesting that ``vehicles manufactured for operation by
persons with disabilities'' be added in active portions of FMVSS No.
208, as had been included in superseded portions of the standard.
Though such a request is outside the scope of this final rule and
requires additional analysis, NHTSA may consider similar language in
future rulemakings.
VII. Amendments to Various FMVSSs
This section discusses comments received on proposed amendments to
various FMVSSs.
FMVSS Nos. 203, Impact Protection for the Driver From the Steering
Control System and 204, Steering Control Rearward Displacement
NHTSA proposed modifying the application section (S2) of FMVSS Nos.
203 and 204 to state that the standards do not apply to vehicles
without steering controls. The agency tentatively determined that the
proposed changes
[[Page 18582]]
would not reduce vehicle safety because, if no steering control is
present at the seating position where the driver's seat would normally
be located, that seating position would become a passenger seat that is
still subject to the protection afforded by the requirements of FMVSS
No. 201.
Several commenters supported the proposed wording change, and no
commenter opposed. NHTSA is adopting the change. In their comments to
the NPRM the American Trucking Association stated their belief that
FMVSS No. 204 applied to heavy trucks. In response to this comment we
would like to clarify that FMVSS No. 204 does not apply to trucks with
a GVWR over 10,000 lb.
The Center for Auto Safety (CAS) discussed implications for
vehicles with configurations that could change (i.e., a vehicle could
have configurations with steering controls and without), but such
controls do not meet the definition of a manually operated driving
control while stowed. The agency believes that no change is necessary
to address the CAS concern, because it is already addressed by virtue
of the fact that when the steering control is not stowed, both FMVSS
Nos. 203 and 204 apply (unless otherwise excluded).
FMVSS No. 207, Seating Systems--Driver's Seat Requirement
NHTSA proposed to modify a requirement that a vehicle have a
driver's seat (FMVSS No. 207, S4.1), to specify instead that a driver's
seat would be required only for vehicles with manually operated driving
controls. By virtue of the new definition of driver's seat (``driver's
designated seating position'') and ``manually operated driving
controls,'' a driver's seat inherently has immediate access to such
controls. Therefore, the proposed addition to S4.1 would clarify that a
vehicle equipped with ADS, without traditional driving controls, need
not have a driver's seat.
Most commenters responding to this issue (the California State
Transportation Agency (CalSTA), GM, CAS) favored or were neutral on the
proposal. GM noted that the NPRM's use of the term ``manually operated
driving control'' as used in the requirement for a driver's seat in
FMVSS No. 207 was incorrectly singular and instead should be plural.
NHTSA agrees with this comment and has adopted the correction in the
final rule.
Tesla asked NHTSA to reconsider this requirement, stating that,
``in certain circumstances involving dual-mode vehicles, the driver's
designated seating position may become a passenger's designated seating
position (e.g., when the manually operated driving controls are
stowed).'' Tesla stated that in such cases, there may be no driver's
designated seating position, which could create uncertainty about
compliance with FMVSS 207, S4.1 for dual-mode vehicles.
NHTSA does not understand how the situation Tesla describes creates
uncertainty about S4.1 certification, since the driver's seat
requirement is predicated on the presence of driving controls. If the
vehicle were dual-mode with stowable controls, the manufacturer would
need to provide a seat so that when the controls are in place, the seat
would be available. Although such a system would be unnecessary, a
manufacturer could provide a system that stows the driver's seat when
the controls are stowed.
FMVSS No. 214, Side Impact Protection
Zoox commented that the first sentence of FMVSS No. 214, S12.2.1(c)
is unnecessary. This section of the standard refers to the positioning
of the arms of the test dummy. The NPRM proposed adding a sentence to
assure that the specification would apply if the vehicle had multiple
front seat passenger dummies. However, since the specification would
apply to any dummy, the additional sentence is redundant. NHTSA agrees
with Zoox's assessment and is deleting the unnecessary text.
FMVSS No. 220, School Bus Rollover Protection
The Alliance suggested that in S5.2(b), the term ``occupant
compartment'' should be substituted for ``passenger and driver
compartment.'' NHTSA did not propose changes to FMVSS No. 220 because
the agency does not believe any are necessary.
We decline to make the requested change to FMVSS No. 220 because
the agency continues to believe no changes are necessary. We note that
a lack of a driver simply indicates that there is only a passenger
compartment.
FMVSS No. 226--Ejection Countermeasure Readiness Telltales
The agency stated in the preamble of the NPRM that it would not
address telltales and warnings as they relate to ADS vehicles where
there is no requirement for any occupant to be seated in what is
currently considered the driver's DSP.\51\ The NPRM stated that this is
a broad topic that will be discussed in a future notice focused solely
on these issues, where the agency can engage stakeholders on those
issues requiring additional policy and technical discussion. The
proposed regulatory text from the NPRM (in S4.2.2 of FMVSS No. 226)
included changes that inadvertently would have required the ejection
mitigation countermeasure readiness indicator to be visible to the
occupant of any DSP for vehicles without a driver's DSP.
---------------------------------------------------------------------------
\51\ The preamble stated (85 FR at 17630): ``The Agency notes
that other barriers, such as those involving the ejection mitigation
countermeasure indicator included in FMVSS No. 226, would be more
appropriately addressed in the Agency's planned future notice
relating to the appropriate applicability of telltale requirements
in ADS-equipped vehicles.''
---------------------------------------------------------------------------
This final rule does not proceed with this proposal. Changes to the
ejection mitigation readiness indicator in FMVSS No. 226 were not
intended to be included in the scope of this rulemaking. The agency
will take the comments received on this issue into consideration when
developing its next actions related to telltales and indicators for
ADS-equipped vehicles.
FMVSS No. 226, Ejection Mitigation--Modified Roof Definition
FMVSS No. 226 excludes ``modified roof vehicles'' from the standard
(S2). The existing FMVSS No. 226 definition of ``modified roof'' (in
S3) uses the term ``driver's compartment.'' NHTSA proposed to make a
simple substitution of ``occupant compartment'' to replace ``driver's
compartment.'' We noted that this change would affect the applicability
of the standard to all vehicles. However, we expected that it would not
have any substantive effect on non-ADS vehicles, i.e., we expected that
the driver's compartment and the occupant compartment would be
identical and requested comment on our expectation.
This final rule adopts the proposed change. Only CalSTA commented
on this aspect of the proposal, and they did so in agreement with the
change. CalSTA asserted that this modification will increase occupant
safety. NHTSA does not have information demonstrating that this change
affects the level of protection provided by current requirements, since
the modification does not expand applicability.
VIII. Effective Date
This final rule is effective 180 days after date of publication in
the Federal Register, with optional early compliance permitted. 49
U.S.C. 30111(d) states that a FMVSS may not become effective before the
180th day the standard is prescribed unless good cause is shown that a
different effective
[[Page 18583]]
date is in the public interest. This final rule makes modifications to
existing FMVSSs in a way that does not require manufacturers of
traditional vehicles to modify their products. Moreover, providing for
optional early compliance will allow manufacturers to benefit
immediately from the flexibility afforded by the modifications to the
FMVSSs included in this final rule, providing the same relief as if the
effective date were earlier.
IX. Cost and Benefit Impacts of This Final Rule
A Final Regulatory Impact Analysis (FRIA) can be found in the
docket for this final rule. A summary of the FRIA findings is provided
below. The cost impacts of this rule will depend on the per-vehicle
costs savings to each vehicle that would no longer need certain manual
controls, times the number of vehicles produced each year that will be
produced without those controls. The Agency has reliable information on
the former category, given that we generally know the current costs of
this equipment, but can only estimate the broader effects. Thus, NHTSA
calculated the impact of the final rule on costs by analyzing
production cost savings arising from forgoing the installation of
manual steering controls. These cost savings are partially offset by
incremental costs associated with augmenting safety equipment in the
left front seating position to make that position equivalent to the
right front seating position, i.e., when what would have previously
been a driver's seating position would become a passenger seating
position in an ADS-DV without manual controls.\52\
---------------------------------------------------------------------------
\52\ An ADS-DV is defined as ``[a] vehicle designed to be
operated exclusively by a level 4 or level 5 ADS for all trips
within its given operational design domain (ODD) limitations (if
any).'' High driving automation (Level 4) is defined as ``[t]he
sustained and ODD-specific performance by an ADS of the entire
dynamic driving task (DDT) and DDT fallback without any expectation
that a user will respond to a request to intervene.'' Full driving
automation (Level 5) is defined as ``[t]he sustained and
unconditional (i.e., not ODD-specific) performance by an ADS of the
entire DDT and DDT fallback without any expectation that a user will
respond to a request to intervene.'' SAE J3016_201806 Taxonomy and

The ranges of estimates were identified within an uncertainty
analysis addressing uncertainty in the average level of cost savings
that would be achieved by ADS-DV manufacturers. The uncertainty
analysis centered on identifying plausible ranges of the per-vehicle
cost savings, with corresponding assumptions regarding the
distributions of values across each range (i.e., the likelihood of
observing a particular value). The uncertainty analysis generated
50,000 simulated outcomes, across which the mean and percentile values
reported in Table IX-2 were identified. In addition to the above ranges
of estimates, the Agency performed a sensitivity analysis in which 30
percent of ADS-DV sales in 2050 are comprised of dual-mode vehicles.
See the FRIA for the results of that analysis.
Although attempting to project the number of vehicles that may
benefit from these savings is, of course, highly uncertain, NHTSA has
conducted an analysis that shows how these cost savings would look if
these types of vehicles became more present in the fleet, as explained
in greater detail in the FRIA. NHTSA assumed that light-duty vehicle
sales would follow the identical baseline path projected in the
Corporate Average Fuel Economy (CAFE) Model \54\ through 2032 (the last
year specified in the baseline), and then would continue to grow at the
average annual growth rate in the baseline from 2027-2032
(approximately 0.2 percent per year; the projected baseline growth rate
was also approximately 0.2 percent per year for 2027-2032 in the CAFE
Model) for each year after 2032, growing to 18.7 million new light-duty
vehicles sold in 2050. NHTSA assumed that the share of new light-duty
vehicle sales comprised of ADS-DVs would reach 31 percent in the year
2050, based on the EIA scenario described above; \55\ thus, new ADS-DV
sales in 2050 are assumed to be equal to 31 percent of 18.7 million, or
5.8 million. Based on these assumptions, NHTSA estimates that the final
rule would save ADS-DV manufacturers and consumers approximately $2.5
billion in the year 2050 ($2.7 billion in production cost savings,
offset partially by $0.2 billion in incremental costs) at a three-
percent discount rate; and approximately $0.7 billion in the year 2050
($0.9 billion in production cost savings, offset partially by
approximately $0.1 billion in incremental costs) at a seven-percent
discount rate.

The estimated cost impacts above represent the subset of potential
impacts that are quantifiable (albeit with considerable uncertainty)
under the available information. NHTSA identified five unquantified
benefit impacts associated with the final rule: impacts on fuel
consumption, impacts on safety, incremental producer and consumer
surplus, changes in administrative burden, and changes in manufacturer
uncertainty. The final rule could affect per-vehicle fuel consumption
by changing the mass of ADS-DVs. NHTSA expects ADS-DV mass to either
decrease (due to the removal of currently required equipment) slightly
or remain essentially unchanged (due to the addition of automated
steering components that offset the mass savings of the removed
equipment) under the final rule. NHTSA acknowledges that, in principle,
ADS-DV mass could increase (if vehicle seating configurations and
amenities are changed sufficiently when exploiting the reduction in
design constraints when removing manual steering controls) under the
final rule. Conversely, ADS-DV net mass could decrease for cases where
vehicles are used for travel without occupants (e.g., automated
deliveries or empty running between trips with occupants). However, we
do not have data to support any specific projections in changes in
vehicle mass.
In any event, current corporate average fuel economy (CAFE)
requirements are based on a vehicle's ``footprint,'' and thus any
change in a vehicles mass will not affect a manufacturer's obligations
under that program. Finally, as stated in the NPRM, NHTSA has not
attempted to address the revisions that may be necessary to provide
regulatory certainty for manufacturers that wish to self-certify ADS-
equipped vehicles with unconventional seating arrangements. The final
rule is assumed to have no effect on the per-mile risk of travel in
ADS-DVs, as it does not revise, remove, or establish anything
associated with their safety performance. That is, the removal of
manual steering controls is not assumed to offer any direct safety
benefit or detriment for travel in ADS-DVs. However, it is feasible
that changes in ADS-DV demand associated with the final rule (e.g., due
to changes in vehicle design or decreases in cost) could increase the
use of ADS-DVs. In turn, safety outcomes associated with the final rule
would be equal to the net effects of: (1) Changes in per-mile fatality
and injury risk for travel that is shifted from conventional vehicles
to ADS-DVs; and (2) incremental fatalities and injuries for travel in
ADS-DVs that would not have taken place in any vehicle otherwise. It is
difficult to project net safety impacts associated with the final rule
without information on: (1) Per-mile fatality and injury risk for ADS-
DVs and conventional vehicles over time; and (2) demand for travel in
ADS-DVs and conventional vehicles as a function of ADS-DV price and
design attributes.
NHTSA recognizes that incremental consumer and producer surplus
under the final rule would accrue in addition to the production cost
savings estimated in the preceding section. That is, by reconfiguring
seating configurations and amenities to exploit the lack of manual
steering controls, ADS-DV manufacturers would generate incremental
consumer and producer surplus as consumers' willingness-to-pay
increases. However, NHTSA does not have sufficient information
available on the demand and supply of ADS-DVs and their substitutes to
estimate the components of incremental consumer and producer surplus
that are not captured within the estimates of production cost savings.
Thus, the share of incremental consumer and producer surplus not
comprised of the cost savings identified in the preceding section is an
unquantified benefit.
The final rule would lead to a reduction in the number of standards
from which manufacturers of ADS-DVs would have to seek exemptions. The
reduction in exemption requests would be associated with a reduction in
administrative costs for both manufacturers and NHTSA. NHTSA does not
have sufficient information to establish a specific estimate of
administrative cost savings. However, the cost savings would be
expected to be small relative to the production cost savings associated
with the rule.
A less tangible, but still important, expected impact of the final
rule would be a reduction in uncertainty for manufacturers of ADS-
equipped vehicles. The final rule provides clarity to manufacturers on
constraints to developing FMVSS-compliant ADS-equipped vehicles. In
turn, developmental paths for ADS-equipped vehicles could be
implemented with greater precision and efficiency. The reduction in
uncertainty could reduce not only the costs associated with
manufacturing ADS-equipped vehicles, but also the time it would take to
bring these vehicles to the market. An accelerated development timeline
would be a benefit both to manufacturers and consumers.
X. Regulatory Notices and Analyses
Executive Order 12866, Executive Order 13563, and DOT Regulatory
Policies and Procedures
NHTSA has considered the impacts of this rulemaking action under
E.O. 12866, ``Regulatory Planning and Review'' (58 FR 51735, October 4,
1993), E.O. 13563, ``Improving Regulation and Regulatory Review,'' and
DOT regulatory requirements. This final rule is ``significant'' and was
reviewed by OMB. This action is significant because it raises novel
legal and policy issues surrounding the regulation of vehicles equipped
with ADS and is the subject of much public interest and has anticipated
annual economic impacts greater than $100 million. NHTSA has prepared a
Final Regulatory Impact Analysis (FRIA) for this final rule, which can
be found in the docket for this final rule. The cost savings of this
final rule are described in the preamble and discussed in greater
detail in the accompanying FRIA.
Regulatory Flexibility Act
Pursuant to the Regulatory Flexibility Act (5 U.S.C. 601 et seq.,
as amended by the Small Business Regulatory Enforcement Fairness Act
(SBREFA) of 1996), whenever an agency is required to publish a notice
of proposed rulemaking or final rule, it must prepare and make
available for public comment a regulatory flexibility analysis that
describes the effect of the rule on small
[[Page 18585]]
entities (i.e., small businesses, small organizations, and small
governmental jurisdictions). The Small Business Administration's
regulations at 13 CFR part 121 define a small business, in part, as a
business entity ``which operates primarily within the United States.''
(13 CFR 121.105(a)(1)). No regulatory flexibility analysis is required
if the head of an agency certifies the proposed or final rule will not
have a significant economic impact on a substantial number of small
entities. SBREFA amended the Regulatory Flexibility Act to require
Federal agencies to provide a statement of the factual basis for
certifying that a proposed or final rule will not have a significant
economic impact on a substantial number of small entities.
I certify that this final rule will not have a significant economic
impact on a substantial number of small entities. This final rule
finalizes NHTSA's proposal of amendments to and clarifications of the
application of existing occupant protection standards to vehicles
equipped with ADS that also lack traditional manual controls. This
final rule will apply to small motor vehicle manufacturers who wish to
produce ADS without manual controls and with conventional seating
arrangements (i.e., forward-facing, front row seats). In the NPRM,
NHTSA analyzed current small manufacturers and current small ADS
developers in detail in the Preliminary Regulatory Impact Analysis
(PRIA) for the NPRM, and found that none of the entities listed in the
analysis would be impacted by this rulemaking. NHTSA received no
comments on this analysis. For the reasons discussed in the PRIA and
set forth in the FRIA, NHTSA concludes this rulemaking will not have a
significant economic impact on a substantial number of small entities.
Executive Order 13132 (Federalism)
NHTSA has examined this final rule pursuant to Executive Order
13132 (64 FR 43255, August 10, 1999) and concluded that no additional
consultation with States, local governments or their representatives is
mandated beyond the rulemaking process. The agency has concluded that
the rulemaking will not have sufficient federalism implications to
warrant consultation with State and local officials or the preparation
of a federalism summary impact statement. This final rule will not have
``substantial direct effects on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.''
NHTSA rules can preempt in two ways. First, the National Traffic
and Motor Vehicle Safety Act contains an express preemption provision:
When a motor vehicle safety standard is in effect under this chapter, a
State or a political subdivision of a State may prescribe or continue
in effect a standard applicable to the same aspect of performance of a
motor vehicle or motor vehicle equipment only if the standard is
identical to the standard prescribed under this chapter. 49 U.S.C.
30103(b)(1). It is this statutory command by Congress that preempts any
non-identical State legislative and administrative law addressing the
same aspect of performance.
The express preemption provision described above is subject to a
savings clause under which ``[c]ompliance with a motor vehicle safety
standard prescribed under this chapter does not exempt a person from
liability at common law.'' 49 U.S.C. 30103(e). Pursuant to this
provision, State common law tort causes of action against motor vehicle
manufacturers that might otherwise be preempted by the express
preemption provision may be preserved. However, the Supreme Court has
recognized the possibility of implied preemption of such State common
law tort causes of action by virtue of NHTSA's rules--even if not
expressly preempted.
This second way that NHTSA rules can preempt is dependent upon the
higher standard effectively imposed through a State common law tort
judgment against the manufacturer, notwithstanding the manufacturer's
compliance with the NHTSA standard, creating an obstacle to the
accomplishment and execution of that standard. If and when such a
conflict does exist--for example, when the standard at issue is both a
minimum and a maximum standard--the State common law tort cause of
action is impliedly preempted. See Geier v. American Honda Motor Co.,
529 U.S. 861 (2000).
Pursuant to E.O. 13132, NHTSA has considered whether this final
rule could or should preempt State common law causes of action. The
agency's ability to announce its conclusion regarding the preemptive
effect of one of its rules reduces the likelihood that preemption will
be an issue in any subsequent tort litigation. Under the principles
enunciated in Geier it is possible that a rule of State tort law could
conflict with a NHTSA safety standard if it created an obstacle to the
accomplishment and execution of that standard. Since this final rule
translates existing occupant protection standards to vehicles equipped
with alternative cabin configurations that lack manual driving
controls, NHTSA does not currently foresee the likelihood of any such
tort requirements and does not have a basis for concluding that such a
conflict exists.
NHTSA solicited comments from the States and other interested
parties on this assessment of issues relevant to E.O. 13132 in the
NPRM. While one commenter touched on the organization's general support
for the concept of federalism, it did not assert that the rulemaking
was anything but an appropriate balance between State and Federal
regulation.
Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et. seq., as added by
the Small Business Regulatory Enforcement Fairness Act of 1996,
generally provides that before a rule may take effect, the agency
promulgating the rule must submit a rule report, which includes a copy
of the rule, to each House of the Congress and to the Comptroller
General of the United States. NHTSA will submit a report containing
this rule and other required information to the U.S. Senate, the U.S.
House of Representatives, and the Comptroller General of the United
States prior to publication of the rule in the Federal Register. A
major rule cannot take effect until 60 days after it is published in
the Federal Register. This action is a ``major rule'' as defined by 5
U.S.C. 804(2). This rule will be effective sixty days after the date of
publication in the Federal Register.
Executive Order 12988 (Civil Justice Reform)
When promulgating a regulation, Executive Order 12988 specifically
requires that the agency must make every reasonable effort to ensure
that the regulation, as appropriate: (1) Specifies in clear language
the preemptive effect; (2) specifies in clear language the effect on
existing Federal law or regulation, including all provisions repealed,
circumscribed, displaced, impaired, or modified; (3) provides a clear
legal standard for affected conduct rather than a general standard,
while promoting simplification and burden reduction; (4) specifies in
clear language the retroactive effect; (5) specifies whether
administrative proceedings are to be required before parties may file
suit in court; (6) explicitly or implicitly defines key terms; and (7)
addresses other important issues affecting clarity
[[Page 18586]]
and general draftsmanship of regulations.
Pursuant to this Order, NHTSA notes as follows. The preemptive
effect of this final rule is discussed above in connection with
Executive Order 13132. NHTSA notes further that there is no requirement
that individuals submit a petition for reconsideration or pursue other
administrative proceeding before they may file suit in court.
Executive Order 13045 (Protection of Children From Environmental Health
and Safety Risks)
Executive Order 13045, ``Protection of Children from Environmental
Health and Safety Risks,'' (62 FR 19885; April 23, 1997) applies to any
proposed or final rule that: (1) Is determined to be ``economically
significant,'' as defined in E.O. 12866, and (2) concerns an
environmental health or safety risk that NHTSA has reason to believe
may have a disproportionate effect on children. If a rule meets both
criteria, the Agency must evaluate the environmental health or safety
effects of the rule on children, and explain why the rule is preferable
to other potentially effective and reasonably feasible alternatives
considered by the Agency.
This final rule is not expected to have a disproportionate health
or safety impact on children. Consequently, no further analysis is
required under Executive Order 13045.
Executive Order 13609, Promoting International Regulatory Cooperation
Executive Order 13609, ``Promoting International Regulatory
Cooperation,'' promotes international regulatory cooperation to meet
shared challenges involving health, safety, labor, security,
environmental, and other issues and to reduce, eliminate, or prevent
unnecessary differences in regulatory requirements. NHTSA has analyzed
this final rule under the policies and Agency responsibilities of
Executive Order 13609, and has determined this rule would have no
effect on international regulatory cooperation.
Paperwork Reduction Act
Under the Paperwork Reduction Act of 1995 (PRA), a person is not
required to respond to a collection of information by a Federal Agency
unless the collection displays a valid OMB control number. This final
rule imposes no new reporting requirements on any person.
National Technology Transfer and Advancement Act and 1 CFR Part 51
Under the National Technology Transfer and Advancement Act of 1995
(NTTAA) (Pub. L. 104-113), ``all Federal agencies and departments shall
use technical standards that are developed or adopted by voluntary
consensus standards bodies, using such technical standards as a means
to carry out policy objectives or activities determined by the agencies
and departments.'' Voluntary consensus standards are technical
standards (e.g., materials specifications, test methods, sampling
procedures, and business practices) that are developed or adopted by
voluntary consensus standards bodies, such as SAE. The NTTAA directs us
to provide Congress, through OMB, explanations when we decide not to
use available and applicable voluntary consensus standards.
Pursuant to the above requirements, the agency conducted a review
of voluntary consensus standards to determine if any were applicable to
this final rule. NHTSA searched for, but did not find, voluntary
consensus standards directly applicable to the amendments adopted in
this final rule. Neither is NHTSA aware of any international
regulations or Global Technical Regulation (GTR) activity addressing
the subject of this final rule.
SAE Standard J826-1980 was previously approved for use in Sec.
571.208 and that approval continues unchanged.
Unfunded Mandates Reform Act
Section 202 of the Unfunded Mandates Reform Act of 1995 (UMRA)
requires Federal agencies to prepare a written assessment of the costs,
benefits, and other effects of proposed or final rules that include a
Federal mandate likely to result in the expenditure by State, local, or
tribal governments, in the aggregate, or by the private sector, of more
than $100 million annually (adjusted for inflation with base year of
1995). Before promulgating a rule for which a written statement is
needed, section 205 of the UMRA generally requires the agency to
identify and consider a reasonable number of regulatory alternatives
and adopt the least costly, most cost-effective, or least burdensome
alternative that achieves the objectives of the rule. The provisions of
section 205 do not apply when they are inconsistent with applicable
law. Moreover, section 205 allows the agency to adopt an alternative
other than the least costly, most cost-effective, or least burdensome
alternative if the agency publishes with the final rule an explanation
of why that alternative was not adopted.
This final rule does not contain a mandate that would impose costs
on any of the entities listed above of more than $100 million annually
(adjusted for inflation with base year of 1995). As a result, the
requirements of Section 202 of the Act do not apply.
National Environmental Policy Act
NHTSA has analyzed this final rule for the purposes of the National
Environmental Policy Act. The agency has determined that implementation
of this final rule will not have any significant impact on the quality
of the human environment.
Regulation Identifier Number (RIN)
The Department of Transportation assigns a regulation identifier
number (RIN) to each regulatory action listed in the Unified Agenda of
Federal Regulations. The Regulatory Information Service Center
publishes the Unified Agenda in April and October of each year. You may
use the RIN contained in the heading at the beginning of this document
to find this action in the Unified Agenda.

S16.2.10.3 Seat position adjustment. If the front right outboard
passenger seat does not adjust independently of the front left outboard
seat, the front left outboard seat shall control the final position of
the front right outboard passenger seat. If an inboard passenger seat
does not adjust independently of an outboard seat, the outboard seat
shall control the final position of the inboard passenger seat.
* * * * *
S16.3.2.1.4 Bench seats. Position the midsagittal plane of the
dummy vertical and parallel to the vehicle's longitudinal centerline
and aligned within 10 mm (0.4 in) of the center
of the steering control.
* * * * *
S16.3.2.1.8 If needed, extend the legs slightly so that the feet
are not in contact with the floor pan. Let the thighs rest on the seat
cushion to the extent permitted by the foot movement. Keeping the leg
and the thigh in a vertical plane, place the foot in the vertical
longitudinal plane that passes through the centerline of the
accelerator pedal. Rotate the left thigh outboard about the hip until
the center of the knee is the same distance from the midsagittal plane
of the dummy as the right knee 5 mm (0.2 in).
Using only the control that primarily moves the seat fore and aft,
attempt to return the seat to the full forward position. If either of
the dummy's legs first contacts the steering control, then adjust the
steering control, if adjustable, upward until contact with the steering
control is avoided. If the steering control is not adjustable, separate
the knees enough to avoid steering control contact. Proceed with moving
the seat forward until either the leg contacts the vehicle interior or
the seat reaches the full forward position. (The right foot may contact
and depress the accelerator and/or change the angle of the foot with
respect to the leg during seat movement.) If necessary to avoid contact
with the vehicles brake or clutch pedal, rotate the test dummy's left
foot about the leg. If there is still interference, rotate the left
thigh outboard about the hip the minimum distance necessary to avoid
pedal interference. If a dummy leg contacts the vehicle interior before
the full forward position is attained, position the seat at the next
detent where there is no contact. If the seat is a power seat, move the
seat fore and aft to avoid contact while assuring that there is a
maximum of 5 mm (0.2 in) distance between the vehicle interior and the
point on the dummy that would first contact the vehicle interior. If
the steering control was moved, return it to the position described in
S16.2.9. If the steering control contacts the dummy's leg(s) prior to
attaining this position, adjust it to the next higher detent, or if
infinitely adjustable, until there is 5 mm (0.2 in) clearance between
the control and the dummy's leg(s).
S16.3.2.1.9 For vehicles without adjustable seat backs, adjust the
lower neck bracket to level the head as much as possible. For vehicles
with adjustable seat backs, while holding the thighs in place, rotate
the seat back forward until the transverse instrumentation platform of
the head is level to within 0.5 degree, making sure that
the pelvis does not interfere with the seat bight. Inspect the abdomen
to ensure that it is properly installed. If the torso contacts the
steering control, adjust the steering control in the following order
until there is no contact: Telescoping adjustment, lowering adjustment,
raising adjustment. If the vehicle has no adjustments, or contact with
the steering control cannot be eliminated by adjustment, position the
seat at the next detent where there is no contact with the steering
control as adjusted in S16.2.9. If the seat is a power seat, position
the seat to avoid contact while assuring that there is a maximum of 5
mm (0.2 in) distance between the steering control as adjusted in
S16.2.9 and the point of contact on the dummy.
* * * * *
S16.3.2.3.2 Place the palms of the dummy in contact with the outer
part of the steering control rim at its horizontal centerline with the
thumbs over the steering control rim.
S16.3.2.3.3 If it is not possible to position the thumbs inside the
steering control rim at its horizontal centerline, then position them
above and as close to the horizontal centerline of the steering control
rim as possible.
S16.3.2.3.4 Lightly tape the hands to the steering control rim so
that if the hand of the test dummy is pushed upward by a force of not
less than 9 N (2 lb) and not more than 22 N (5 lb), the tape releases
the hand from the steering control rim.

S8.4 Adjustable steering controls. Adjustable steering controls are
adjusted so that the steering control hub is at the geometric center of
the locus it describes when it is moved through its full range of
driving positions. If there is no setting detent in the mid-position,
lower the steering control to the detent just below the mid-position.
If the steering column is telescoping, place the steering column in the
mid-position. If there is no mid-position, move the steering control
rearward one position from the mid-position.

S10.2 Vehicle test attitude. When the vehicle is in its ``as
delivered,''
[[Page 18598]]
``fully loaded'' and ``as tested'' condition, locate the vehicle on a
flat, horizontal surface to determine the vehicle attitude. Use the
same level surface or reference plane and the same standard points on
the test vehicle when determining the ``as delivered,'' ``fully
loaded'' and ``as tested'' conditions. Measure the angles relative to a
horizontal plane, front-to-rear and from left-to-right for the ``as
delivered,'' ``fully loaded,'' and ``as tested'' conditions. The front-
to-rear angle (pitch) is measured along a fixed reference on the left
and right front occupant's door sills. Mark where the angles are taken
on the door sills. The left to right angle (roll) is measured along a
fixed reference point at the front and rear of the vehicle at the
vehicle longitudinal center plane. Mark where the angles are measured.
The ``as delivered'' condition is the vehicle as received at the test
site, with 100 percent of all fluid capacities and all tires inflated
to the manufacturer's specifications listed on the vehicle's tire
placard. When the vehicle is in its ``fully loaded'' condition, measure
the angle between the left front occupant's door sill and the
horizontal, at the same place the ``as delivered'' angle was measured.
The ``fully loaded condition'' is the test vehicle loaded in accordance
with S8.1 of this standard (49 CFR 571.214). The load placed in the
cargo area is centered over the longitudinal centerline of the vehicle.
The vehicle ``as tested'' pitch and roll angles are between the ``as
delivered'' and ``fully loaded'' condition, inclusive.

side seat. If the driver and any front outboard passenger seats adjust
independently of each other, adjust both the struck and non-struck side
seats in the manner specified in S10.3.2.
* * * * *
S10.5 Adjustable steering controls. Adjustable steering controls
are adjusted so that the steering control hub is at the geometric
center of the locus it describes when it is moved through its full
range of driving positions. If there is no setting detent in the mid-
position, lower the steering control to the detent just below the mid-
position. If the steering column is telescoping, place the steering
column in the mid-position. If there is no mid-position, move the
steering control rearward one position from the mid-position.

S12.1.2 Positioning a Part 572 Subpart F (SID) dummy in any front
outboard passenger seating position.
(a) * * *
(1) For a bench seat. The upper torso of the test dummy rests
against the seat back. The midsagittal plane of the test dummy is
vertical and parallel to the vehicle's longitudinal centerline. For
vehicles with manually operated driving controls the midsagittal plane
of the test dummy is the same distance from the vehicle's longitudinal
centerline as would be the midsagittal plane of a test dummy positioned
in the driver's seating position under S12.1.1(a)(1). For vehicles
without manually operated driving controls the midsagittal plane of the
test dummy shall be vertical and parallel to the vehicle's longitudinal
centerline, and passes through any front outboard passenger seat's
SgRP.
* * * * *
S12.1.3 * * *
(a) * * *
(1) For a bench seat. The upper torso of the test dummy rests
against the seat back. The midsagittal plane of the test dummy is
vertical and parallel to the vehicle's longitudinal centerline, and, if
possible, the same distance from the vehicle's longitudinal centerline
as the midsagittal plane of a test dummy positioned in the driver's
seating position under S12.1.1(a)(1) or left front passenger seating
positioned under S12.1.2(a)(1) in vehicles without manually operated
driving controls. If it is not possible to position the test dummy so
that its midsagittal plane is parallel to the vehicle longitudinal
centerline and is at this distance from the vehicle's longitudinal
centerline, the test dummy is positioned so that some portion of the
test dummy just touches, at or above the seat level, the side surface
of the vehicle, such as the upper quarter panel, an armrest, or any
interior trim (i.e., either the broad trim panel surface or a smaller,
localized trim feature).
* * * * *
S12.2.1 * * *
(c) Arms. Place the dummy's upper arms such that the angle between
the projection of the arm centerline on the mid-sagittal plane of the
dummy and the torso reference line is 40[deg] 5[deg]. The
torso reference line is defined as the thoracic spine centerline. The
shoulder-arm joint allows for discrete arm positions at 0, 40, and 90
degree settings forward of the spine.

S12.3.2 * * *
(a) * * *
(4) Bench seats. Position the midsagittal plane of the dummy
vertical and parallel to the vehicle's longitudinal centerline and
aligned within 10 mm (0.4 in) of the center of
the steering control rim.
* * * * *
(8) If needed, extend the legs slightly so that the feet are not in
contact with the floor pan. Let the thighs rest on the seat cushion to
the extent permitted by the foot movement. Keeping the leg and the
thigh in a vertical plane, place the foot in the vertical longitudinal
plane that passes through the centerline of the accelerator pedal.
Rotate the left thigh outboard about the hip until the center of the
knee is the same distance from the midsagittal plane of the dummy as
the right knee 5 mm (0.2 in). Using only the
control that moves the seat fore and aft, attempt to return the seat to
the full forward position. If either of the dummy's legs first contacts
the steering control, then adjust the steering control, if adjustable,
upward until contact with the steering control is avoided. If the
steering control is not adjustable, separate the knees enough to avoid
steering control contact. Proceed with moving the seat forward until
either the leg contacts the vehicle interior or the seat reaches the
full forward position. (The right foot may contact and depress the
accelerator and/or change the angle of the foot with respect to the leg
during seat movement.) If necessary to avoid
[[Page 18599]]
contact with the vehicle's brake or clutch pedal, rotate the test
dummy's left foot about the leg. If there is still interference, rotate
the left thigh outboard about the hip the minimum distance necessary to
avoid pedal interference. If a dummy leg contacts the vehicle interior
before the full forward position is attained, position the seat at the
next detent where there is no contact. If the seat is a power seat,
move the seat fore and aft to avoid contact while assuring that there
is a maximum of 5 mm (0.2 in) distance between the vehicle interior and
the point on the dummy that would first contact the vehicle interior.
If the steering control was moved, return it to the position described
in S10.5. If the steering control contacts the dummy's leg(s) prior to
attaining this position, adjust it to the next higher detent, or if
infinitely adjustable, until there is 5 mm (0.2 in) clearance between
the control and the dummy's leg(s).
(9) * * *
(ii) Vehicles with adjustable seat backs. While holding the thighs
in place, rotate the seat back forward until the transverse
instrumentation platform angle of the head is level to within 0.5 degrees, making sure that the pelvis does not interfere with
the seat bight. (If the torso contacts the steering control, use
S12.3.2(a)(10) before proceeding with the remaining portion of this
paragraph.) If it is not possible to level the transverse
instrumentation platform to within 0.5 degrees, select the
seat back adjustment position that minimizes the difference between the
transverse instrumentation platform angle and level, then adjust the
neck bracket to level the transverse instrumentation platform angle to
within 0.5 degrees if possible. If it is still not possible
to level the transverse instrumentation platform to within 0.5 degrees, select the neck bracket angle position that
minimizes the difference between the transverse instrumentation
platform angle and level.
(10) If the torso contacts the steering control, adjust the
steering control in the following order until there is no contact:
Telescoping adjustment, lowering adjustment, raising adjustment. If the
vehicle has no adjustments or contact with the steering control cannot
be eliminated by adjustment, position the seat at the next detent where
there is no contact with the steering control as adjusted in S10.5. If
the seat is a power seat, position the seat to avoid contact while
assuring that there is a maximum of 5 mm (0.2 in) distance between the
steering control as adjusted in S10.5 and the point of contact on the
dummy.
* * * * *
S12.3.3 * * *
(a) * * *
(2) Fully recline the seat back, if adjustable. Place the dummy
into any passenger seat, such that when the legs are positioned 120
degrees to the thighs, the calves of the legs are not touching the seat
cushion.
* * * * *
(4) Bench seats. Position the midsagittal plane of the dummy
vertical and parallel to the vehicle's longitudinal centerline and the
same distance from the vehicle's longitudinal centerline, within 10 mm (0.4 in), as the midsagittal plane of the
driver dummy, if there is a driver's seating position. Otherwise, the
midsagittal plane of any front outboard passenger dummy shall be
vertical, parallel to the vehicle's longitudinal centerline, and pass,
within 10 mm (0.4 in), through the seating
reference point of the seating that it occupies.
