Federal Motor Vehicle Safety Standards; Occupant Crash Protection

AGENCY: National Highway Traffic Safety Administration (NHTSA), 
Department of Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This final rule amends Federal Motor Vehicle Safety Standard 
(FMVSS) No. 208, ``Occupant crash protection,'' updating the child 
restraint systems (CRSs) listed in the standard. NHTSA uses the CRSs to 
test the performance of advanced air bag suppression and low risk 
deployment systems in either suppressing or deploying the air bag in a 
low-risk manner in the presence of a CRS. The amendments will ensure 
that the CRSs used by NHTSA to test advanced air bags are 
representative of the current CRS market and will make it easier for 
vehicle manufacturers and test laboratories to acquire CRSs for testing 
purposes.

DATES: 
    Effective date: October 21, 2024.
    Petition for reconsideration: If you wish to petition for 
reconsideration of this rule, your petition must be received by October 
7, 2024.
    Compliance date: This final rule adopts a phase-in of the revised 
appendix. The phase-in begins on September 1, 2025, when forty percent 
of a manufacturer's applicable light vehicles must comply with the 
revised appendix. By September 1, 2026, all applicable light vehicles 
must comply with the revised appendix. We are also allowing optional 
early compliance.

I. Executive Summary

    This final rule amends FMVSS No. 208 to update the child restraint 
systems (CRSs) listed in appendix A-1 of the standard. The CRSs in 
appendix A-1 are used by NHTSA to test advanced air bag suppression or 
low risk deployment systems to ensure that they mitigate the risk of 
harm to children and infants by either suppressing or deploying the air 
bag in a low-risk manner in the presence of a child in a CRS. NHTSA is 
updating appendix A-1 to reflect the changes to the availability of 
CRSs in the marketplace since 2008 when the appendix was last updated.
    The amendments finalized in this rule will replace all the CRSs 
listed in appendix A-1. This final rule will allow a phase-in of the 
amendment to give manufacturers reasonable time to certify their 
advanced air bag systems using the new CRSs, with optional early 
compliance permitted. To effectuate the phase-in using the regulatory 
framework of FMVSS No. 208, this update will move the CRSs that are now 
in appendix A-1 to appendix A and reference the new proposed CRSs in 
appendix A-1.
    This final rule will allow the agency to test advanced air bags 
with CRSs that are more representative of the current CRS market. 
Furthermore, since the last significant update to the appendix was in 
2008, many CRS models listed in the current appendix have been 
discontinued and are difficult and time-consuming to acquire. This 
update to appendix A-1 will make it easier for vehicle manufacturers 
and test laboratories to acquire the CRSs for testing purposes.

II. Background

A. Background on Air Bag Systems

    NHTSA Has Required Air Bag Systems in Vehicles since the Late 
1990s, but Early Air Bag Systems Risked Injury to Certain Populations. 
To prevent or mitigate the risk of injuries or fatalities in frontal 
crashes, Federal Motor Vehicle Safety Standard (FMVSS) No. 208, 
Occupant crash protection,\1\ requires passenger vehicles to be 
equipped with seat belts and frontal air bags. Although FMVSS No. 208 
did not require frontal air bags on passenger cars until model year 
(MY) 1998 and on multipurpose passenger vehicles and light trucks until 
MY 1999, air bags were already in widespread use by the early 1990s. 
These early-generation air bags were highly effective in protecting 
occupants in frontal crashes but caused a number of injuries and 
fatalities to certain occupants who were especially vulnerable to air 
bag-related risks. Frontal air bags posed the largest threat to 
occupants vulnerable to air bag-related risks.
---------------------------------------------------------------------------

    \1\ 49 CFR 571.208.
---------------------------------------------------------------------------

    Since the introduction of air bag systems into vehicles, NHTSA has 
maintained two consistent messages relating to children and air bag 
systems. First, NHTSA has consistently recommended that children under 
the age of 13 be seated in the back seat of vehicles. If consumers were 
to always seat their children--whether positioned in a CRS or not--in 
the back seats of their vehicles, air bags would pose very little risk 
to children. Frontal air bags pose a bigger risk to children than side 
curtain air bags, which pose very little threat to any occupant. Since 
vehicle back seats are only equipped with side curtain air bags, the 
risk of harm from air bags is significantly reduced for children 
sitting in the back seat. However, there are scenarios when a child 
needs to be seated in the front seat of a vehicle, and there are 
scenarios where a caretaker may simply decide that the child will be 
safe sitting in the front seat of a vehicle. To ensure that children 
(and others who may be harmed by air bag systems) who are seated in the 
front seat of vehicles are protected from air bag-related harm, NHTSA 
has long maintained that the long-term solution was the development and 
widespread implementation of advanced air bag systems that can sense 
the weight and size of the occupant seated and adjust air bag 
deployment to protect at-risk passengers. However, during the 1990s, 
when air bag-related injuries and fatalities emerged as a safety 
problem, advanced air bags were still a nascent technology.
    To provide time for the development and dissemination of advanced 
air bag systems into new vehicle production, and to address safety 
concerns posed by pre-advanced air bag systems in vehicles already on 
the road, NHTSA implemented an array of measures designed to protect 
those passengers most susceptible to air bag-related injuries. Although 
early air bag systems posed threats to several different populations, a 
particular focus of these measures was to protect children from air 
bag-related injuries and fatalities. Early data indicated that children 
were at particularly significant risk of harm from air bags. The data 
indicated that

[[Page 67871]]

children who were both seated in CRSs and seated without CRSs were at 
risk of serious injury or death when seated in a position with a 
frontal air bag. Because of the agency's significant concern for the 
safety of children, NHTSA took multiple actions throughout the 1990s to 
protect children from potential harm from air bags.
    NHTSA's Recommendations Targeted at Behavioral Changes to Protect 
Children from Air Bag Systems. First, the agency began providing CRS 
recommendations informing caretakers how and where they should equip 
child restraints in a vehicle. NHTSA's recommendation has always been 
to place CRSs in the back seat of vehicles. There are different CRSs 
for children of different ages, and NHTSA's recommendations change 
based off of the child's age and size.\2\ It is important to note that 
NHTSA recommends that the child be properly restrained in the back seat 
of a vehicle for all these different stages.
---------------------------------------------------------------------------

    \2\ https://www.nhtsa.gov/vehicle-safety/car-seats-and-booster-seats.
---------------------------------------------------------------------------

    NHTSA used several communications to further the agency's goal of 
changing behavior to protect children from early air bag systems. For 
example, in the early 1990s, the agency conducted testing that showed 
that using a rear-facing child restraint in the front seat of a vehicle 
where frontal air bags were active presented a significant risk to 
child occupants. In December of 1991, the agency issued a Consumer 
Advisory warning owners of rear-facing child restraints to not use such 
devices in the front seat of a vehicle equipped with a passenger air 
bag. Throughout the 1990s, NHTSA released several additional News 
Releases on this issue. On October 27, 1995, after several fatalities 
of children seated in air bag-equipped seating positions, NHTSA issued 
a warning in a press release, titled ``SAFETY AGENCY ISSUES WARNING ON 
AIR BAG DANGER TO CHILDREN.'' In the press release, the agency warned 
that children sitting in air bag-equipped seating positions not 
restrained by a seat belt could be seriously injured or killed by an 
air bag. During the late 1990s, the agency also published several 
articles in widely circulated journals and periodicals on the dangers 
air bags pose to children. The agency has continued this education 
campaign by publishing information on NHTSA's website on the dangers 
air bags pose to children.
    NHTSA Regulatory Action Taken to Protect Children from Early Air 
Bag Systems. In addition to efforts to change caretaker behavior, NHTSA 
has also taken regulatory action on this issue. In 1993, the agency 
issued a final rule that, in part, required vehicles equipped with air 
bags to include labels on sun visors providing specific cautions, 
including a warning not to install rear-facing child seats in the front 
passenger seat. The agency took further regulatory action in 1994, when 
it required rear-facing child restraints manufactured on or after 
August 15, 1994, to include a warning label against using the restraint 
in any vehicle seating position equipped with a frontal air bag. 
Finally, in 1995 and 1997, NHTSA took regulatory action targeted at 
vehicle technology when the agency created a process for vehicle owners 
to petition the agency to allow vehicle owners or lessees to have an 
air bag on-off switch installed in their vehicle.\3\ Although on-off 
switches have been an effective tool in protecting children from air 
bag systems, as discussed above, the agency has consistently viewed 
advanced air bag systems as the best protection for children seated in 
air bag-equipped seating positions. Air bag on-off switches carry a 
significant risk of misuse, as individuals who would typically benefit 
from the protection of air bag systems may forget to turn a system back 
on after turning it off for a child passenger. The agency believed the 
advent of advanced air bag technology would essentially resolve this 
misuse risk by being able to sense the occupant seated in an air bag-
equipped seat and activating or deactivating the system based on the 
occupant.

---------------------------------------------------------------------------

B. Background on Advanced Air Bag Systems

    On May 12, 2000, NHTSA issued the Advanced Air Bag Rule \4\ to 
reduce the frequency and severity of air bag-related injuries to small 
adults and young children. To this end, the Advanced Air Bag Rule 
amended FMVSS No. 208 to add new performance requirements for the front 
passenger air bag in the presence of a child in a CRS.
---------------------------------------------------------------------------

    \4\ 65 FR 30680.
---------------------------------------------------------------------------

    Although the Advanced Air Bag rule was targeted at protecting all 
individuals from potential harm from air bags, specific requirements 
were included that were targeted at protecting children. The Advanced 
Air Bag Rule allows manufacturers to provide child protection using one 
of three compliance options. The first option requires the front 
passenger air bag system to automatically suppress when a child 
(whether in a CRS or not) is present (``suppression''). The second 
option requires that the front passenger air bag deploys only at a low 
level of force when a child (whether in a CRS or not) is present (``low 
risk deployment'' or ``LRD''). For these first two options, the vehicle 
must provide passenger-side protections for child-sized test dummies in 
various positions, including in a CRS. The third compliance option 
requires the tracking of the passenger occupant's motion and suppresses 
the air bag if they are too close to the air bag (``dynamic automatic 
suppression system'' or ``DASS''). To comply using dynamic automatic 
suppression, a manufacturer must develop an acceptable test procedure, 
which must be adopted into FMVSS No. 208 through an expedited 
rulemaking procedure. To date, no manufacturer has attempted to certify 
using the DASS option. FMVSS No. 208 permits vehicle manufacturers to 
choose different compliance options for different performance tests and 
is technology neutral with regard to how a vehicle complies.
    For tests that involve air bag performance in the presence of 
anthropomorphic test dummies in CRSs, manufacturers are required to 
certify that their vehicles will comply with the advanced air bag 
requirements when tested by NHTSA. FMVSS No. 208 sets out requirements 
that advanced air bag systems must meet to comply with the standard 
when tested with several different anthropomorphic test dummies. For 
the purposes of advanced air bag suppression systems, the standard 
outlines test procedures for testing with the 12-month-old CRABI dummy, 
the 3-year-old child dummy, and the 6-year-old child dummy.\5\ The 
standard allows NHTSA to test suppression systems with any of these 
dummies and also includes procedures for testing the suppression 
systems with these dummies equipped in CRSs to ensure suppression 
systems can differentiate between an adult sitting in an air bag 
equipped seat and a CRS restraining a child. For each of the test 
procedures explaining how to test with each respective dummy, the 
standard identifies which subpart in appendix A-1 to reference in 
determining which CRSs to test with. For example, for the 3-year-old 
dummy automatic suppression test, the standard instructs the tester 
that the system must function with the dummy restrained in any child 
restraint specified in sections C and D of appendix A-1.
---------------------------------------------------------------------------

    \5\ FMVSS No. 208 S20; S21; S23.
---------------------------------------------------------------------------

    As part of that test procedure in FMVSS No. 208, NHTSA listed the 
CRSs that the agency would test within

[[Page 67872]]

appendix A of FMVSS No. 208. NHTSA intended for the CRSs listed in 
appendix A to be representative of the array of available CRSs on the 
market across many CRS manufacturers. To keep appendix A up to date, 
NHTSA amended it in final rules issued in December 2001 \6\ and 
November 2003 \7\ to replace certain CRSs that were no longer in 
production and to add two LATCH-compatible CRSs, respectively.\8\
---------------------------------------------------------------------------

    \6\ 66 FR 65375.
    \7\ 68 FR 65179.
    \8\ FMVSS No. 225 requires certain vehicles produced after 
September 1, 2002, to be equipped with lower anchorage systems to 
ensure their proper location and strength for the effective securing 
of child restraints. These systems are commonly referred to as Lower 
Anchors and Tethers for Children (LATCH).
---------------------------------------------------------------------------

    Two CRS-related appendices appear at the end of FMVSS No. 208: 
appendix A and appendix A-1. NHTSA most recently updated appendix A in 
a final rule issued in November 2008.\9\ As part of this final rule, 
NHTSA created ``appendix A-1'' to facilitate phasing in the requirement 
to certify vehicles with the updated CRSs.\10\ Appendices A and A-1 
both still remain at the end of FMVSS No. 208, and, as discussed in 
greater detail below, this final rule updates both appendices.
---------------------------------------------------------------------------

    \9\ 73 FR 66786.
    \10\ The phase-in had the practical effect of permitting up to 
50 percent of a manufacturer's carry-over vehicles to continue to 
certify to the existing appendix for a period. A manufacturer had 
the choice to have new model vehicles or carry-over vehicles of 
established models, or both, comprise the 50 percent of vehicles 
that can be phased in to the requirement to certify to the revised 
appendix A. The ability to carry over a percentage of vehicles for a 
year was designed to alleviate compliance burdens on manufacturers.
---------------------------------------------------------------------------

C. Appendix A-1's Current Framework

    The CRSs listed in appendix A-1 are broken up into four subparts. 
Subpart A lists ``car bed'' CRSs that the agency can use to test the 
suppression system of a vehicle that has been certified as complying 
with S19 of FMVSS No. 208. Subpart B lists rear-facing infant CRSs that 
the agency can use to test the suppression system or the LRD 
capabilities of a vehicle that is certified as complying with S19 of 
FMVSS No. 208. Subpart C lists forward-facing toddler and convertible 
CRSs \11\ that the agency can use to test the suppression system or the 
LRD capabilities of a vehicle that has been certified as complying with 
S19 or S21 of FMVSS No. 208. Subpart D lists CRSs that are or can be 
used as a belt-positioning seat (commonly called belt-positioning 
booster seats (BPBs)) (e.g., combination and 3-in-1 CRSs) and that the 
agency can use to test the suppression system or the LRD capabilities 
of a vehicle that has been certified as complying with S21 or S23 of 
FMVSS No. 208.\12\
---------------------------------------------------------------------------

    \11\ A convertible CRS is a type of CRS with an internal harness 
to secure the child that can be used rear-facing and forward-facing. 
It is used rear-facing with infants (or small toddlers if the CRS 
weight recommendations allow it), and, forward-facing with older and 
larger children. The CRS manufacturer instructs the consumer when to 
turn the convertible CRS around to face forward, based on the weight 
of the child (``turnaround'' weight).
    \12\ ``Belt-positioning seat'' is defined in FMVSS No. 213 S4 as 
``a child restraint system that positions a child on a vehicle seat 
to improve the fit of a vehicle Type II belt system on the child and 
that lacks any component, such as a belt system or a structural 
element, designed to restrain forward movement of the child's torso 
in a forward impact.'' A combination CRS can be used forward-facing 
or as a booster seat. A 3-in-1 CRS is a convertible CRS that can be 
used as a booster seat.
---------------------------------------------------------------------------

    NHTSA's Self-Certification System and Appendix A-1. The Motor 
Vehicle Safety Act prohibits the manufacturing, selling, and importing 
of motor vehicles and motor vehicle equipment that do not comply with 
the FMVSS.\13\ Accordingly, one of NHTSA's most important priorities is 
ensuring that motor vehicles and motor vehicle equipment on the market 
comply with the FMVSS. NHTSA can enforce compliance with the FMVSS 
through statutorily created recall authority as well as by levying 
civil penalties.\14\
---------------------------------------------------------------------------

    \13\ 49 U.S.C. 30112.
    \14\ 49 U.S.C. 30120.
---------------------------------------------------------------------------

    To determine whether motor vehicle equipment complies with the 
FMVSS, NHTSA must test that equipment. NHTSA publishes its test 
procedures for each FMVSS so the public is aware of how NHTSA will 
determine compliance with the relevant FMVSS. Although NHTSA publishes 
its test procedures, the Motor Vehicle Safety Act makes clear that 
manufacturers have the responsibility to certify their own motor 
vehicles and motor vehicle equipment for compliance with the FMVSS.\15\ 
This self-certification regime puts the onus on manufacturers to police 
themselves when introducing motor vehicles or motor vehicle equipment 
into the market, which means that although NHTSA publishes its own test 
procedures, manufacturers are free to test their products for 
compliance in other ways. In other words, NHTSA's test procedures are 
publicly available as part of the FMVSS, but manufacturers are under no 
obligation to compliance test using NHTSA's procedures--a 
manufacturer's only obligation is to certify compliance, but it may do 
so using its own testing methods. Appendix A-1 is part of the test 
procedures of FMVSS No. 208.
---------------------------------------------------------------------------

    \15\ 49 U.S.C. 30115.
---------------------------------------------------------------------------

    Appendix A-1 informs manufacturers which CRSs NHTSA will test with 
when the agency compliance tests advanced air bag systems. 
Manufacturers are under no obligation to test with the CRSs that NHTSA 
tests with, meaning that appendix A-1 sets merely a floor for the CRSs 
a manufacturer may test with. In fact, when the agency decided to 
include appendix A-1 as part of FMVSS No. 208, it did so with the 
expectation that manufacturers would test more than just the seats 
included in the appendix, as a manufacturer's priority should be 
ensuring that its advanced air bag systems function properly with all 
CRSs on the market.

III. Development of the 2020 NPRM

    On October 29, 2020, NHTSA published an NPRM to update appendix A-
1.\16\ The purpose of this proposed update was to ensure that the list 
of seats included in appendix A-1 reflects the current CRS market. The 
CRS market is constantly changing, with companies releasing new 
versions of seats, new models of seats, and novel seat designs every 
year. Because the appendix was last updated in 2008, many of the seats 
in the appendix are no longer sold by manufacturers. This means that 
both NHTSA and manufacturers have to find second-hand versions of many 
of the seats listed in the current appendix for compliance testing. 
Over time, it has become increasingly difficult to procure some of the 
seats in the appendix. Furthermore, there are certain trends in the CRS 
market that the current seats listed in the appendix do not account 
for. For example, as discussed in more detail below, data indicate that 
CRSs have become heavier overall. This change could pose a potential 
issue for advanced air bag system sensing technology, as sensors may 
not be able to detect the difference between an adult seated in an air 
bag-equipped seat and a heavy child restraint with a child seated in 
the restraint. Under the current list, NHTSA would not be testing many 
of those heavier seats to ensure compliance with FMVSS No. 208. The 
agency not only wanted to make the CRSs in the appendix easier to 
procure, but also wanted to ensure that the seats included in the 
appendix were a representative sample of the current CRS market.
---------------------------------------------------------------------------

    \16\ 85 FR 68541, ``Occupant crash protection.''
---------------------------------------------------------------------------

    NHTSA's Methodology in Choosing the Proposed CRSs. When deciding 
which seats to replace and include in the proposed update to appendix 
A-1, NHTSA considered whether a particular CRS had been a high-volume 
model, whether it had mass and dimensions that are representative of 
many CRSs on the market, whether its mass and

[[Page 67873]]

dimensions represented outliers, and whether a variety of CRS 
manufacturers were represented in the appendix. The agency also 
assessed whether the assortment of CRSs in the appendix ensured that 
NHTSA would be adequately testing the robustness of air bag automatic 
suppression systems under real world conditions. Additionally, NHTSA 
conducted a systematic evaluation of the CRSs currently in appendix A, 
and of data collected through the agency's Ease of Use (EOU) 
program.\17\
---------------------------------------------------------------------------

    \17\ The EOU program is a program in which NHTSA rates different 
usability aspects of CRSs currently on the market. It is part of the 
New Car Assessment Program (NCAP), and is updated annually. The 
details of this data collection process are discussed in the 
November 2008 final rule (73 FR 66786).
---------------------------------------------------------------------------

    The agency assessed child restraint system physical dimensions and 
weight (mass) to identify which CRSs have dimensions that were 
representative of the average restraint in today's market, and which 
were possible outliers (see docketed Technical Assessment for data). In 
looking for outliers, the agency considered CRSs with dimensions and 
weight that were markedly outside of those of the ``average'' CRS. The 
goal in identifying outliers was to ensure the updated appendix was 
fully representative of the current CRS market. Additionally, the 
agency identified which CRSs had high production totals (based on 
confidential manufacturer data) to determine which CRSs were likely to 
have the greatest market share.
    In choosing which CRSs to include in the updated appendix, the 
agency sought to ensure that advanced air bag systems would be designed 
and calibrated to perform satisfactorily when used with a wide range of 
CRSs. For example, because rear-facing CRSs with either low or high 
seat back heights can pose challenges for LRD systems, the agency 
sought to include rear-facing CRSs of varying seat back heights for LRD 
testing purposes. Similarly, because the agency believes that certain 
features like handles and sunshields on rear-facing infant carrier CRSs 
can lead to false readings by vision-based sensors used in some 
advanced air bag systems, the agency included rear-facing CRSs that 
have handles and sunshields in the appendix. Based on this methodology, 
the agency proposed a series of deletions and additions to appendix A-1 
in the 2020 NPRM. The agency also proposed updating two existing 
entries in appendix A-1 to reflect model name changes. For detailed 
information on the agency's proposed additions and deletions, please 
reference the NPRM.
    The comment period for the NPRM closed on December 28, 2020. Eight 
comments (from six commenters) were received in response to the NPRM, 
and a discussion of those comments with the agency's responses can be 
found in section VI below.

IV. Amendments to Appendices A and A-1 as Part of This Final Rule

    As described above, there are currently two appendices to FMVSS No. 
208: appendices A and A-1. Appendix A currently lists the CRSs that 
were adopted as part of the advanced air bag final rule in 2000. 
Appendix A-1 currently lists the CRSs that were adopted as part of the 
first appendix A update in 2008. In the 2008 final rule, the agency 
decided to adopt a phase-in process for manufacturer compliance, and 
keeping the CRSs from the advanced air bag rule as part of the standard 
was necessary for the agency to continue compliance testing during the 
phase-in period.
    After considering the factors for decision-making discussed in the 
previous section of this preamble, and after analyzing feedback from 
both the public and CRS manufacturers, NHTSA is making three sets of 
amendments to appendices A and A-1 as part of this final rule. First, 
the agency is deleting all seats currently listed in appendix A from 
the standard. Because the phase-in period for the 2008 update has long 
since passed, there is no reason to keep the seats currently listed in 
appendix A as part of the standard. Second, the agency is moving the 
seats adopted as part of the 2008 appendix update (the current appendix 
A-1) to appendix A. Third, and lastly, the agency is adding 20 new CRSs 
to appendix A-1, which will constitute the update that the following 
discussion focuses on.
    To help clarify the table below, it is important to note that five 
CRSs are listed in both subparts C and D for testing purposes, which is 
why the ``TOTAL AFTER CHANGES TOTAL'' column reflects 25 in table 1 
below. (In the current appendix A-1 four CRSs are listed in both 
subparts C and D.) Table 1 shows the deletions and additions by subpart 
in appendix A-1.

Deletions......................................            1            6           10            6           23
Total after changes............................            1            6           10            8           25
----------------------------------------------------------------------------------------------------------------
** There are five CRSs listed in both subparts C and D for testing purposes, so there are only 20 CRSs total in
  the appendix.

    Tables 2 and 3 below provide the detailed make and model 
information for NHTSA's deletions and additions to appendix A-1. There 
are some differences between the list of deletions and additions 
proposed in the NPRM and the deletions and additions adopted in this 
final rule, and a detailed discussion of those changes and the 
rationales behind those decisions can be found in the section below. 
All the deletions proposed in the NPRM are being adopted in this final 
rule, and the reasons for each deletion were discussed in detail in the 
NPRM. Generally, the proposed deletions were based on CRSs that did not 
offer any unique characteristics, CRSs that were produced in small 
quantities, or CRSs that are no longer in production and have not been 
for some time. Because the proposed deletions are all being adopted, 
NHTSA recommends that interested members of the public reference the 
NPRM for specific explanations of deletions for individual seats. There 
are two additional deletions and additions being adopted in this final 
rule. Because there are some differences between the proposed list of 
additions and deletions in the NPRM and the additions and deletions 
being adopted in this final rule, detailed explanations of those 
changes can be found in the following section. As discussed above, 
although this final rule says that the agency is ``deleting'' all seats 
from the current appendix A-1, those CRSs will still appear in the

[[Page 67874]]

appendix to FMVSS No. 208, but they will appear under appendix A.
---------------------------------------------------------------------------

    \18\ Certain seats listed in appendices A and A-1 contain a 
series of ``x's'' at the end of their model names. These x's 
represent specific soft material designs and colors for those seats. 
Because soft material designs and colors do not have an impact on 
FMVSS No. 208 air bag suppression compliance testing, the agency 
does not specify soft material colors and designs in either appendix 
A or A-1.

Differences Between the NPRM and the Final Rule

    There are several differences between the 2020 NPRM and this Final 
Rule. Most notably, NHTSA decided to replace 6 of the 18 seats proposed 
as additions to appendix A-1 in the NPRM and update the model names for 
6 of the proposed CRS additions. The agency made these decisions based 
on feedback from manufacturers and commenters. After publishing the 
NPRM, NHTSA contacted the CRS manufacturers of the proposed added seats 
to verify the production and design status of each proposed addition. 
The agency followed this same process when NHTSA last updated appendix 
A-1 in 2008.
    In the explanations below for why certain CRSs have been chosen as 
replacements for the proposed CRSs, the term ``footprint'' is used a 
number of times. For clarification, when using the term ``footprint,'' 
the agency is referring to the general size of the CRS base that 
contacts the seat cushion. The footprint on every CRS model is unique 
and some air bag suppression systems have difficulty sensing CRSs with 
certain footprints.

[[Page 67875]]

    The NPRM also proposed an update to model identification 
information for two seats: the Evenflo Discovery Adjust Right and the 
Britax Roundabout E9L02XX. After consulting with the manufacturers, 
instead of updating the model information for these two seats, the 
agency has decided to delete them from appendix A-1. Therefore, in 
addition to the changes to 12 of the 18 proposed additions to appendix 
A-1, NHTSA will be adding two different seats to replace the Evenflo 
Discovery Adjust Right and the Britax Roundabout E9L02XX as part of 
this Final Rule.
    A detailed discussion of the rationales for each change between the 
NPRM and Final Rule can be found in the subsections below.

A. Deletion of the Evenflo Discovery Adjust Right and Addition of the 
Evenflo NurtureMax Into Subpart B

    As noted above, the NPRM proposed a model name update for the 
Evenflo Discovery Adjust Right to the Evenflo Nurture #362xxxxx. Based 
on input from Evenflo, and as shown on their website, the Evenflo 
Nurture model is no longer available. Because the goal of this Final 
Rule is to update appendix A-1 to include CRSs that are representative 
of today's CRS market and readily available, it would be illogical to 
include a CRS that is not listed on a manufacturer's website. Instead 
of keeping the Evenflo Discovery Adjust Right/Nurture in appendix A-1, 
this Final Rule will delete this CRS from subpart B, and will add the 
Evenflo NurtureMax as a replacement rear-facing CRS in subpart B. The 
Evenflo NurtureMax is not considered an equivalent replacement because 
it does not have the same structural design as the Discovery Adjust 
Right/Nurture, but it does have similar characteristics (e.g., the 
Evenflo NurtureMax is a lightweight rear-facing CRS with a shorter than 
average footprint and it is a popular CRS in the U.S.).

B. Addition of the Evenflo Litemax 35 #3305xxxxx Instead of the Evenflo 
Embrace Into Subpart B

    The NPRM proposed the addition of the Evenflo Embrace #315xxxxx, a 
rear-facing infant seat that was described as lightweight and popular, 
into subpart B. Based on feedback from the manufacturer and because the 
Evenflo Embrace model is no longer listed as part of the lineup of 
rear-facing CRSs on Evenflo's website, this model is no longer being 
added to the appendix. After evaluating other available CRSs with 
similar characteristics as the Evenflo Embrace the agency decided to 
add the Evenflo Litemax, which is also a popular, lightweight, rear-
facing infant CRS with a long footprint.

C. Addition of the Cybex Cloud Q With SensorSafe Instead of the Cybex 
Aton 2 Into Subpart B

    The NPRM proposed the addition of the Cybex Aton 2, a rear-facing 
infant seat, into subpart B. The NPRM described the Cybex Aton 2 as 
being a heavy infant seat and having a unique footprint because of its 
shape and because it is designed to accommodate a load leg. Due to 
feedback from the manufacturer and because the Cybex Aton 2 is no 
longer listed on Cybex's website, the agency is instead adding the 
Cybex Cloud Q with SensorSafe,\19\ which has an essentially equivalent 
base as the Cybex Aton 2 and is just slightly heavier, which is 
acceptable since the Aton 2 was proposed as a heavy rear-facing CRS 
(see docketed Technical Assessment for dimensions and pictures). The 
Cybex Cloud Q also has a load leg like the Cybex Aton 2.
---------------------------------------------------------------------------

    \19\ SensorSafe is a technology Cybex has recently integrated 
into the chest clip of its CRSs that provides alerts to a mobile app 
about the child's safety.
---------------------------------------------------------------------------

D. Addition of the Nuna Pipa RX With Pipa RELX Base Instead of the 
Britax B-Safe 35 Into Subpart B

    The NPRM proposed the addition of the Britax B-Safe 35 #E1A72xx, a 
rear-facing infant seat, into subpart B. The NPRM described it as being 
heavy with a large footprint and as capturing a large portion of the 
infant CRS market. Based on input from Britax, we decided against 
including this CRS in the appendix. After evaluating other available 
rear-facing infant CRSs on the market, we are adding the Nuna Pipa RX 
with the Pipa RELX base, which has similar characteristics as the 
Britax B-Safe 35. The Nuna Pipa RX with the Pipa RELX base is a heavy 
rear-facing infant CRS, with a wide and long footprint.

E. Deletion of the Britax Roundabout EL02XX and Addition of the Nuna 
Rava #CS05116CVR Into Subpart C

    As noted above, the NPRM proposed a model name update for the 
Britax Roundabout E9L02XX to reflect its new name, the Britax 
Allegiance #E9LR4xx. Based on input from Britax, and because the Britax 
Allegiance model is no longer listed on Britax's website as part of its 
lineup of CRSs, it would be illogical to include a CRS that is no 
longer part of Britax's CRS lineup. Instead of keeping the Britax 
Roundabout E9L02XX/Allegiance #E9LR4xx in appendix A-1, this final rule 
will delete this CRS from subpart C, and will add the Nuna Rava as a 
replacement convertible CRS in subpart C. The Nuna Rava has similar 
characteristics as the Britax Allegiance (e.g., it is a heavy 
convertible CRS with a wide footprint; see the docketed Technical 
Assessment for dimensions and pictures). Additionally, the Nuna Rava is 
also a popular CRS.

F. Addition of the Britax Poplar #E1C93xx Instead of the Britax 
Marathon ClickTight Into Subpart C

    The NPRM proposed the addition of the Britax Marathon ClickTight 
#E1A38xx, a convertible CRS, into subpart C. It was described as a 
heavy convertible CRS with a wide footprint. Based on feedback from 
Britax, we have decided against adding the proposed Marathon ClickTight 
model and we are instead adding the Britax Poplar #E1C93xx into subpart 
C. The manufacturer indicated that the Britax Poplar is dimensionally 
similar to the Britax Marathon ClickTight, so the agency views it is as 
a suitable alternative.

G. Addition of the Graco Contender Slim Instead of the Graco Contender 
65 Into Subpart C

    The NPRM proposed the addition of the Graco Contender 65, a 
convertible CRS, into subpart C. The NPRM described it as a lighter 
than average convertible CRS with a narrow and deep footprint. Based on 
feedback from the manufacturer we have decided not to add the proposed 
Contender model and the agency is instead adding the Graco Contender 
Slim model, which is essentially an equivalent model to the Graco 
Contender 65, into subpart C. Their footprint and dimensions are very 
similar, and the Contender Slim is a lighter than average convertible 
with a narrow footprint (see docketed Technical Assessment for 
dimensions and pictures).

H. Addition of the Evenflo Chase Plus #307xxxxx Instead of the Evenflo 
Chase #306xxxxx Into Subparts C and D

    The NPRM proposed the addition of the Evenflo Chase #306xxxxx, a 
combination CRS, into subparts C and D. After consulting with the 
manufacturer, the agency has decided to instead add the Evenflo Chase 
Plus. The manufacturer indicated that the Evenflo Chase Plus will be 
more widely available than the Evenflo Chase, and that the CRSs are 
nearly equivalent (see docketed Technical Assessment for dimensions and 
pictures). It is also a popular combination CRS. Accordingly, the 
agency is adding the Evenflo Chase Plus #307xxxxx, into subparts C and 
D.

[[Page 67876]]

I. Correction and Name Updates for 6 Proposed CRSs

    The NPRM proposed the addition of the Cybex Eternis, a 3-in-1 CRS, 
into subparts C and D. Based on input from the CRS manufacturer, the 
correct model name is the Cybex Eternis S with SensorSafe. Accordingly, 
the agency has added the ``S'' designation to the name of the CRS as 
well as the ``SensorSafe'' designation.
    The NPRM proposed the addition of the Safety 1st Dreamride SE LATCH 
#IC238xxx. Based on input from the manufacturer, the correct model name 
is the Safety 1st Dreamride with LATCH #IC238xxx. Accordingly, the 
agency has updated the name of this CRS as part of this final rule.
    The NPRM proposed the addition of the Graco 4Ever All-in-1. Based 
on input from the manufacturer, the correct model name is the Graco 
4Ever DLX. Accordingly, the agency has updated the name of this CRS as 
part of this final rule.
    The NPRM proposed the addition of the Cosco Finale #BC121xxx. Based 
on input from the manufacturer, the updated model name for this seat is 
the Cosco Finale #BC110xxx. Accordingly, the agency has updated the 
name of this CRS as part of this final rule.
    The NPRM proposed the addition of the Graco Backless Turbobooster. 
Based on input from the manufacturer, the correct model name is the 
Graco Turbobooster Backless Booster Seat. Accordingly, the agency has 
updated the name of this CRS as part of this final rule.
    The NPRM proposed the addition of the Britax Grow with You 
#E1C19xx. Based on input from the manufacturer, the correct model name 
is the Britax Grow with You Clicktight #E1C19xx. Accordingly, the 
agency has updated the name of this CRS as part of this final rule.

V. Discussion of Comments to the NPRM

A. Summary of Comments

    There were eight comments submitted in response to the NPRM.\20\ 
Commenters touched on a variety of topics, including the CRSs proposed 
in the NPRM, concerns about the frequency with which the agency updates 
appendix A-1, test procedures, the proposed regulatory text, and 
compliance dates. Some commenters also had concerns with the potential 
costs and effort necessary for manufacturers to comply with testing 
using the new CRSs proposed in the NPRM. The agency's summary of 
comments and responses can be found in the subsections below.
---------------------------------------------------------------------------

    \20\ The Alliance for Automotive Innovation submitted two sets 
of supplemental comments (August 2021 and August 2023).
---------------------------------------------------------------------------

B. The CRSs Proposed in the NPRM

    The Juvenile Products Manufacturers Association (JPMA) submitted a 
comment providing feedback on the CRSs NHTSA proposed in the NPRM. 
Table 4 shows the feedback JPMA provided in its comment on specific 
seats proposed in the NPRM, along with the agency's response to that 
feedback.

                               early 2021.
Britax Grow with You          Recommended      NHTSA chose the
 #E1C19xx.                     replacing with   ClickTight model because
                               non-ClickTight   it is the more popular
                               model            version of the CRS.
                               #E1C144xx.       NHTSA has added the

C. Availability of the Safety 1st Dreamride SE Latch #IC238

    The Alliance for Automotive Innovation (The Alliance) commented 
specifically on NHTSA's proposed inclusion of the Safety 1st Dreamride 
SE Latch #IC238. The Alliance argued that, because the Safety 1st 
Dreamride SE Latch #IC238 is one of the only available infant car beds 
on the market, NHTSA should create a formal means for automakers to 
procure seats listed in appendix A-1.
    Agency Response: NHTSA will not be creating a formal process to 
acquire CRSs listed in appendix A-1 as part of this final rule. The 
Alliance is correct that part of the agency's rationale in updating 
appendix A-1 is to ensure manufacturers can more easily acquire the 
CRSs listed in appendix A-1. As stated previously, it can be difficult 
to acquire the CRSs currently listed in appendix A-1 because many of 
the CRSs have been discontinued by manufacturers. This final rule will 
resolve that issue by updating appendix A-1 to include CRSs currently 
on the market. However, under the Safety Act, manufacturers are 
required to self-certify their own motor vehicles and motor vehicle 
parts.\21\ As part of this certification process, NHTSA strives to 
ensure that manufacturers and the public are aware of how the agency 
will test motor vehicles and motor vehicle parts for compliance with 
the FMVSS. That being said, once NHTSA has made clear how it will test 
a motor vehicle or motor vehicle part, it is up to the manufacturer to 
ensure its products comply. The agency believes it has significantly 
improved the ease with which manufacturers can acquire the CRSs in 
appendix A-1 by ensuring all CRSs in appendix A-1 are currently 
available for purchase. In particular, although the Safety 1st 
Dreamride SE Latch #IC238 is one of the only available infant car beds 
on the market, it is available for purchase by the public. 
Manufacturers do not need to rely on NHTSA to procure CRSs for them. 
Accordingly, the agency believes that manufacturers should easily be 
able to acquire the CRSs listed as part of this final rule. For the 
reasons discussed above, NHTSA will not be creating a formal process 
for manufacturers to acquire the CRSs listed in appendix A-1 as part of 
this final rule.

D. Frequency of Updates to the Appendix

    The Automotive Safety Council commented that it would like NHTSA to 
adopt an official frequency with which the agency will update appendix 
A-1 going forward. JPMA also mentioned in its comment that it would 
appreciate more frequent updates to appendix A-1 from NHTSA. The 
Alliance also commented on the need for a more reliable and consistent 
manner of updating the appendix in its August 2023 supplemental 
comments.
    Agency Response: NHTSA will not be adopting a specific frequency 
for updating appendix A-1 as part of this final rule. As discussed 
earlier in this preamble as well as in the NPRM, the agency is aware 
that a significant amount of time has passed since it last updated 
appendix A-1 in 2008. The agency is aware that this time-lapse has 
rendered appendix A-1 outdated, and many of the seats listed in 
appendix A-1 are no longer in production, which makes it difficult for 
manufacturers to acquire certain CRSs that NHTSA currently tests with. 
One of NHTSA's goals with this final rule is to ensure manufacturers 
can easily acquire the CRSs listed in appendix A-1. Another goal with 
this final rule is to ensure the CRSs NHTSA uses to test for compliance 
with FMVSS No. 208 are representative of the CRS market. The agency 
believes that committing to a specific frequency to update appendix A-1 
would not align with the ever-changing CRS market. Having the 
discretion necessary to choose when to update appendix A-1 will allow 
the agency to adapt as the CRS market adapts. Furthermore, committing 
to a specified time frame for updating the appendix would likely 
interfere with the agency's ability to manage its rulemaking resources 
as it deems appropriate in light of other priorities and statutory 
mandates and could hamper its ability to respond quickly to changes in 
the CRS industry or air bag system designs. As such, NHTSA is not 
adopting a specific frequency to update appendix A-1 as part of this 
final rule.

E. Test Procedures

i. Testing With the CRABI Dummy
    The Alliance indicated in its comment that it would like 
clarification on test procedure installation for two forward-facing 
CRSs proposed in the NPRM. Specifically, the Alliance requested that 
NHTSA explain how it should test the Cosco Finale DX #BC121 and the 
Chicco MyFit #04079783-0070 with the 12-month-old CRABI dummy when the 
owner's manuals for both of those seats indicate that those CRSs are 
designed to be used for children weighing more than the 12-month-old 
CRABI dummy weighs. The Alliance reiterated its concerns in its August 
2023 supplemental comments.
    Agency Response: As discussed above, NHTSA is correcting the name 
of the Cosco Finale DX #BC121 and is instead including the Cosco Finale 
#BC110 as part of this final rule. According to the manufacturer, this 
is merely a model name change and the seat design and intended use are 
functionally the same, meaning the Alliance's comment still applies. 
FMVSS No. 208, S19.2.1, specifies the use of the 12-month-old dummy for 
suppression testing in any of the CRSs listed in the appendix subparts 
C and D as appropriate. The term ``as appropriate'' is informative 
here, as it makes clear that NHTSA will only suppression test a seat in 
appendix A-1 subparts C and D with the 12-month-old dummy if it is 
appropriate to do so with that seat. As discussed in the

[[Page 67878]]

background section above, FMVSS No. 208 sets out testing requirements 
for advanced air bag systems using the 12-month-old CRABI dummy, the 3-
year-old child dummy, and the 6-year-old child dummy. For all seats 
listed in appendix A-1, NHTSA will only test with the dummies that are 
the appropriate size for each respective CRS according to the 
manufacturer's instructions. Accordingly, because the Cosco Finale DX 
#BC121 and the Chicco MyFit #04079783-0070 are CRSs that are designed 
to restrain children who weigh more than the 12-month-old CRABI dummy, 
NHTSA would not suppression test with the 12-month-old CRABI dummy for 
those CRSs.
ii. Seat Belt Load Requirement
    The Alliance requested clarification of the seat belt cinching 
requirement listed in the FMVSS No. 208 test procedures. The Alliance 
commented that for certain CRSs listed in the NPRM with belt tensioning 
devices, ``it is possible to exceed the 134 N belt load by 80-106 N if 
slack is removed from the belt prior to applying the child seat belt 
tensioning mechanism.'' Furthermore, the Alliance indicated that it is 
concerned that in the field, these belt tensioning mechanisms can 
exceed the belt tension in the manufacturer's compliance testing, and, 
in combination with heavier CRSs, could increase the risk of an 
undesired air bag deployment (e.g., a child heavier than the dummy and 
excessive belt load due to child seat belt tensioning systems could be 
misclassified as a small adult occupant).
    Agency Response: In response to this comment, NHTSA performed 
further testing with CRSs proposed in the NPRM that have belt 
tensioning mechanisms. The agency acknowledges that when these seats 
are installed using the manufacturers' instructions, these seats 
automatically tension past the maximum tension of 134 N described in 
FMVSS No. 208 S20.2.1.5(c). The tension that these seats tension to 
varies depending on the seat they are installed in as well as the 
specific CRS. Accordingly, the agency acknowledges that if the 
manufacturers' instructions for these seats are followed, it would 
likely not be possible to test within the tension range outlined in 
S20.2.1.5(c).
    The agency has decided to include three seats with belt tensioning 
systems as part of this final rule, despite the fact that they likely 
cannot be installed by following the CRS manufacturers' instructions to 
properly perform the test procedure outlined in S20.2.1.5(c). It is 
important to note that, for the S20.2.1.5 test procedure, the standard 
instructs the test conductor to ``secure the child restraint by 
following, to the extent possible, the child restraint manufacturer's 
instructions regarding proper installation . . .'' (emphasis added).
    The agency is aware that there are some CRSs on the market that are 
equipped with belt tensioning systems that may tension past the maximum 
134 N outlined in S20.2.1.5. Accordingly, the agency believes it is 
important to include these CRSs in appendix A, as they represent a 
segment of the CRS market. Through NHTSA's research on belt tensioning 
seats, the agency discovered that it is possible to reduce the tension 
that the belt tensioning devices automatically ratchet to by 
introducing extra belt webbing when installing the CRS on the vehicle 
seat. To clarify how to test with these CRSs according to the 
parameters outlined in S20.2.1.5(c), NHTSA will update its compliance 
test procedures to instruct labs contracted with NHTSA to introduce 
extra belt webbing when installing CRSs with belt tensioning devices. 
The amount of extra webbing that needs to be introduced depends on the 
CRS and the vehicle seat the CRS is installed on, so the agency will 
include in the compliance test procedure a method for achieving the 
required belt tension within the allowable range of zero to 134 N. The 
agency believes this procedure is consistent with the requirements of 
paragraph S20.2.1.5(c) because of the ``to the extent possible'' 
language used in that paragraph.
    The agency decided to keep these CRSs with belt tensioning devices 
as part of this final rule for multiple reasons. First, as discussed in 
the NPRM and in the section above describing the difference between the 
NPRM and the final rule, these seats (Cybex Cloud Q, Britax Poplar, and 
Britax Grow With You ClickTight) represent important parts of the CRS 
market when it comes to the characteristics of each CRS (e.g., weight, 
footprint dimensions and designs). The agency believes that because 
these seats are part of the CRS market and because they have 
characteristics the agency wants to include in the appendix for testing 
the effectiveness of the air bag suppression systems, these seats are 
worth keeping as part of the amended appendix A-1. Second, these CRSs 
equipped with belt tensioning devices were not available the last time 
appendix A-1 was updated in 2008. It is possible that CRSs equipped 
with belt tensioning devices will become more popular as time goes on. 
Accordingly, the agency believes it is important to have CRSs equipped 
with belt tensioning devices as part of appendix A. Although the test 
procedure will test at a lower tension than these three CRSs typically 
tension to, NHTSA believes that there is still a safety benefit to 
testing these CRSs at a reduced tension. Specifically, if an advanced 
air bag system fails to suppress at a tension in the zero to 134 N 
range, it is likely that that advanced air bag system would also fail 
the test at the tighter tension range that the belt tensioning device 
would usually ratchet to. Accordingly, vehicle manufacturers will know 
if their air bag suppression systems are compliant with the specific 
weight and footprint of these CRSs, with the belt tensioned to the 
appropriate test range. For the reasons listed above, the agency has 
decided to keep the CRSs with belt tensioning devices as part of this 
final rule and will update the compliance test procedures to instruct 
labs on how to install the CRSs to the tension range outlined in 
S20.2.1.5(c).
iii. Compliance Concerns With New Heavier CRSs
    The Alliance requested that NHTSA reconsider the CRSs proposed in 
the NPRM, due to concern about the overall shift to include heavier 
CRSs in appendix A-1. They further stated that the NPRM did ``not 
sufficiently address the potential for misclassification of occupants. 
The size and weight of CRSs continue to grow, bringing them (combined 
with their intended child occupants) closer to the size of small 
adults. The narrowing of this gap creates an increasing risk of 
misclassifications by vehicle occupant classification systems (OCS), 
potentially leading to air bag inflation in instances when suppression 
might be the safer outcome. Significant changes to the air bag systems 
and related software will be required to address this matter, along 
with changes to the vehicle instrument panels to accommodate the new 
systems.''
    The Alliance reiterated these concerns in one of its supplemental 
comments. The Alliance argued that NHTSA's crash data demonstrates that 
injury and fatality exposure rates are far greater for smaller stature 
occupants in fatal crashes (i.e., over 13 years old) than for younger 
children (i.e., under 6 years old) because most younger children are 
seated in the back seat of vehicles.\22\ According to the Alliance, 
this reflects that the largest group at risk of injury from frontal air 
bags is smaller statured passengers, not passengers seated in CRSs. The 
Alliance argued that this further supports their argument about

[[Page 67879]]

the potential harm of misclassification by OCSs.
---------------------------------------------------------------------------

    \22\ NHTSA recommends that children under the age of 13 should 
be seat in the back seat of a vehicle.
---------------------------------------------------------------------------

    The Alliance did not provide actual vehicle compliance test data to 
support their claims with regards to the performance of current systems 
with the heavier CRSs. The Alliance suggested that ``NHTSA should 
conduct further analysis to assess the regulatory impact on existing 
vehicle designs when including CRS that are significantly above the 
current threshold values established in appendix A-1, and the potential 
impact this may have on overall occupant safety.'' Furthermore, the 
Alliance argued that the weight of the heavier CRSs in combination with 
the 6-year-old dummy would begin to overlap with the air bag activation 
threshold leading to misclassification by the occupant detection 
system.
    Agency Response: The commenters are correct in their assessment 
that the proposed CRSs in the appendix A-1 update will be heavier 
overall than the previous version of the appendix, which was last 
updated in 2008. Since then, the CRS market has evolved significantly. 
NHTSA has conducted an analysis of recent Ease of Use program data 
(2015-2020 yearly data) and found an increase in the yearly average 
weight of boosters and CRSs that can be used as booster seats, which 
can be seen in table 5 below.

 Table 5--Average Weight of Booster Seats and Available CRS Models That
                      Can Be Used as Booster Seats

2020..................................             14.92             120
------------------------------------------------------------------------

    Additionally, the agency analyzed Ease of Use data as far back as 
2012 to look at whether heavier CRSs were available at that time as 
well. NHTSA found booster seats, and CRSs that can be used as booster 
seats, that are heavier than or have a similar weight as the heavy CRSs 
identified by the Alliance that have been available as far back as 
2012. Examples of such CRSs can be seen in table 6.

----------------------------------------------------------------------------------------------------------------
* These boosters/CRSs were available in subsequent years and possibly previous years as well. We have only
  identified the earliest year the CRS was in the Ease of Use program based on the range of years examined.

    The Alliance requested that NHTSA include CRSs that are consistent 
with the weights of the CRSs currently listed in the appendix. Although 
the agency acknowledges that manufacturers may have to make design 
changes to ensure their advanced air bag systems remain compliant with 
FMVSS No. 208, NHTSA's top priority is passenger safety. As shown 
above, there is a clear trend toward CRSs increasing in weight. To 
ensure vehicle air bag suppression systems protect passengers, the 
agency must ensure that the CRSs being used to test those systems are 
representative of the current CRS market. Basing the weights of the 
CRSs included in appendix A-1 off the CRS market in 2008 would not 
reflect the CRSs that most current parents and caretakers use 
currently. One of NHTSA's goals with this final rule is to make the 
FMVSS No. 208 test procedures more representative of the real world, 
and continuing to test with CRSs from 2008 would do the opposite.
    Furthermore, since the inception of the Advance Air Bag Rule, the 
agency has made clear that it is incumbent on vehicle manufacturers to 
perform their due diligence by developing and testing their advanced 
air bag systems with CRSs that are not limited to appendix A.\23\ 
Accordingly, it is reasonable to

[[Page 67880]]

assume that many manufacturers test their advanced air bag systems with 
more CRSs beyond what is listed in appendix A-1.
---------------------------------------------------------------------------

    \23\ The Advanced Air Bag NPRM (63 FR 49958) required that 
vehicles with suppression systems be tested with any CRS 
``manufactured for sale in the United States between two years and 
ten years prior to the date the model year carline of which the 
vehicle is a part was (or will be) first offered for sale to a 
consumer.'' This was done so ``that vehicle manufacturers take 
account of the variety of different rear facing child restraints in 
use as they design their systems.'' The supplemental NPRM (64 FR 
60556) introduced appendix A, which was developed from a ``more 
comprehensive list represent[ing] the majority of child restraints 
currently on the market. That list was reduced, in part, by 
eliminating similar restraint systems, e.g., restraints that are 
sold as different models but which we believe provide the same 
footprint.'' In the final rule (65 FR 30679) the agency further 
explained its reasoning for the use of a list of CRSs in appendix A. 
We stated that ``we do not believe that manufacturers should have 
the option of certifying to only a limited number of the restraints 
on the list. We do not believe that requiring compliance with seats 
is excessive, given the importance of reliability in a suppression 
system and the fact that the suppression tests are nondestructive. 
Children sitting in the front seat will not receive the benefit of a 
suppression system that does not recognize their presence in the 
seat. If manufacturers believe their planned suppression technology 
is insufficient to detect a wide variety of child restraints, they 
will need to either improve or supplement that technology.''
---------------------------------------------------------------------------

    Lastly, NHTSA initiated testing to investigate the Alliance's 
concerns with the heavier CRSs. Thirteen vehicles were tested, and each 
vehicle was tested with the CRSs in varying modes. The reports from 
this testing will be placed in the docket for this rulemaking.
    This research demonstrated that four of the 13 vehicles tested were 
able to suppress the air bag with all the CRSs used for testing, 
including the three heavier CRSs identified by the Alliance. The 
passenger air bag activation weight threshold was measured for each 
vehicle and the thresholds ranged from 55-85 lb. The weight threshold 
for the four vehicles that suppressed the air bag for all the CRSs and 
modes tested ranged from 56-77 lb. Further, 8 of the 13 vehicles 
complied with the requirements with at least 2 of the 3 heavy CRSs 
identified by the Alliance.
    The agency's testing also revealed that the weight of the CRS does 
not necessarily ultimately determine whether an air bag suppression 
system activates. For instance, one of the tested vehicles (with an air 
bag suppression system weight threshold of 73 lb) was able to meet the 
suppression requirements with two of the three CRSs identified by the 
Alliance (Cybex Eternis and Britax Grow With You), but did not comply 
with the Chicco Myfit, which was the lightest of the three. This result 
seemed to be related to how the Chicco MyFit's footprint loaded the 
system's pressure sensitive bladder.
    The agency testing has shown inconsistent performance for heavier 
CRSs. However, it is clear from the results that systems can be 
designed to correctly identify these CRSs and appropriately suppress 
the air bag. The failure of some vehicles to suppress the air bag in 
the presence of some of the CRSs is concerning and supports the need 
for expeditious inclusion of heavier CRSs in the appendix.
iv. Safety Need for Appendix Update
    The Alliance commented on the limited exposure to air bags for 
children in CRSs since most children are placed in the rear seats and 
because most children in the front passenger seat are restrained only 
by seat belts. The Alliance further noted that ``the CRS list currently 
defined in FMVSS 208 appendix A-1 has been successful in shaping design 
countermeasures that support a positive downward trend in injuries and 
fatalities for both child- and small-stature occupants seated in the 
right-front seating position.''
    Agency Response: NHTSA acknowledges and is encouraged by the 
positive trend of seating children in the back seat. Nonetheless, 
children are sometimes still restrained in a CRS in the front seat. 
Furthermore, as discussed above, there is a clear market trend in CRSs 
becoming heavier on average. This is at least in part due to the rise 
of the all-in-one (also known as the 3-in-one) seat, which has become 
popular with caregivers as they only have to purchase one seat for 
their child, instead of buying new seats as their child grows. 
Offerings in the all-in-one CRS category have significantly grown in 
the CRS industry over the past several years. This is evident in the 
list provided by American Academy of Pediatrics of available all-in-one 
CRSs for 2023.\24\ Additionally, using the 2015-2020 Ease of Use data, 
the agency looked at the number of all-in-one and combination CRSs and 
found an increase in the number of these types of CRSs from 84 in 2015 
to 120 in 2020. Because the market trends point to an overall increase 
in CRS weight, NHTSA believes there is a critical safety need to have 
heavier seats included as part of appendix A-1.

F. Comments on the Proposed Regulatory Text

    In the NPRM, the agency proposed specific amendments to FMVSS No. 
208, to remove the current appendix A (which has been phased out), 
redesignate appendix A-1 as appendix A, and add the new list of CRSs as 
appendix A-1.
    The Alliance commented that, ``Comparing the NPRM which was 
published on October 29, 2020, and the current standard, it seems that 
`S21' has been accidentally deleted. As NHTSA's intention was to 
redesignate `appendix A-1' of the current regulation as `appendix A' in 
the October 29, 2020, NPRM, we believe the section numbers in subpart D 
should be the same (i.e. should refer to `S21 or S23'). See FR page 
68552, proposed FMVSS 208, section D of appendix A.'' The Alliance also 
commented that ``[t]here appears to be an inconsistency in the proposed 
regulations. Comparing proposed FMVSS 208 S14.8 vs. Part 585.35 and 
Part 585.36, it seems that `first' in S14.8 should be `second.' ''
    Agency Response: NHTSA concurs with these comments and has 
corrected the regulatory text as part of this final rule. This 
amendment is reflected in the adopted regulatory text below.

G. Comments on the Compliance Date

    In the NPRM, the agency proposed that the compliance date for the 
proposed requirements be phased in such that at least 50 percent of a 
manufacturer's vehicles manufactured on or after the first September 
1st after the publication date of the final rule would have to be 
certified as meeting FMVSS No. 208 when tested with the CRSs on the 
revised appendix A-1, and all vehicles manufactured on or after the 
second September 1st after the publication date of the final rule would 
have to be so certified.
    The Alliance expressed concerns with the proposed compliance date 
in both its initial comment and one of its supplemental comments. In 
its initial comment it argued that, due to the increased weight of the 
CRSs being tested under the proposed update, manufacturers would have 
to take a series of steps to ensure compliance. The Alliance wrote:

    ``Substantial testing will be required to assess the performance 
of occupant classification systems with the heavier CRS installed. 
Such testing may identify the need for air bag system design 
changes. Changes to air bag size, shape, and inflators may 
necessitate changes to instrument panel design. Suppression may no 
longer be an option for some models with weight-based occupant 
classification sensors. Those models may have to switch from 
suppression to LRD approaches. In that case, the air bag module as 
well as the instrument panel may also need to be re-engineered. 
Significant changes may be required to accommodate the new systems. 
Our initial study indicates that, after further consideration of 
this matter by the affected parties and development of technical 
solutions, additional lead-time will likely be needed to implement 
these strategies, beyond what is proposed by the agency in the NPRM. 
This scenario will require full frontal crash development which 
typically takes more than two years.''

    In its supplemental comment, the Alliance requested that the lead 
time be extended by two years with an additional four-year phase-in to 
allow for manufacturers' evaluation and implementation of design 
changes to advanced air bag systems.

[[Page 67881]]

    Agency Response: As discussed throughout this preamble, the CRS 
market has been trending toward heavier CRSs for some time. Although 
appendix A-1 provides manufacturers with a list of seats that NHTSA 
will test to determine compliance with FMVSS No. 208, the agency made 
it clear in the Advanced Air Bag Final Rule that manufacturers have a 
responsibility to ensure that their advanced airbag systems suppress 
deployment with all seats that are available on the CRS market. 
Accordingly, if manufacturers have been paying attention to the CRS 
market, they should have already begun the process of implementing 
heavier CRSs into their test programs. Furthermore, delaying compliance 
with the updated appendix would likely result in availability issues 
for the CRSs being added to the appendix given the frequent change in 
CRS model names, designs, or discontinuation of CRSs.
    As part of NHTSA's own research, the agency acknowledges that some 
advanced air bag systems will likely have to undergo adjustments to 
comply with the updated appendix A-1. In response to commenters' 
compliance concerns as well as the agency's testing, the agency has 
decided that the phase-in of the revised appendix will be implemented 
in two stages. To ease the burden on manufacturers, NHTSA is amending 
the compliance phase-in to the following: Forty percent of all of a 
manufacturer's light vehicles must comply with the revised appendix by 
September 1, 2025, and all light vehicles must be fully compliant no 
later than September 1, 2026. We are also allowing optional early 
compliance. This change provides relief for an additional 10% of 
vehicles in the first part of the phase-in. However, NHTSA does not 
believe that an extension of the full compliance date beyond the second 
part of the phase-in is warranted or advisable. Among other risks, any 
additional delay raises the chances of inadvertently unsuppressed air 
bag systems in vehicles where certain heavier CRSs have been placed in 
the front seat. The agency encourages vehicle manufacturers to acquire 
sufficient inventory of the CRSs when the final rule is published to 
mitigate availability issues in the future.

VI. Discussion of Benefits and Costs Associated With the Final Rule

    The NPRM discussed how this rule does not amend any of the FMVSS 
No. 208 performance test requirements; it merely updates the list of 
CRSs NHTSA may use for advanced air bag compliance tests. It further 
explained that we cannot quantify the incremental benefits of testing 
with these new CRSs over those listed in the current appendix A-1, due 
to a lack of field performance test data, but that updating the CRSs 
used to assess the performance of advanced air bags addresses that 
potential issue by enabling manufacturers to design advanced air bag 
systems to factor in the features and characteristics of the CRSs used 
today.
    With regards to the costs associated with the rule, the NPRM stated 
that the rule would result in a nominal cost to vehicle manufacturers 
for the purchase of the new CRSs. It provided a conservative cost 
estimate for the one additional CRS and then amortized this cost over 
10 years and 16 million vehicles to get an annual per vehicle cost 
estimate. Essentially, based on the cost of a complete set of all the 
CRSs added, $3,364, it estimated the cost for the one additional CRS 
being added as $168.20 (1/20th of total cost). Then, based on an 
estimated 248 production lines and the assumption that vehicle 
manufacturers will purchase 10 sets of CRSs, the NPRM estimated that 
the total undiscounted 10-year cost to all vehicle manufacturers 
cumulatively would be $417,136 ($168.20 x 248 x 10). Assuming an annual 
production of 16 million vehicles, there would be 160 million vehicles 
for the same time period (16 million x 10 years). Thus, the NPRM 
provided an annual per-vehicle cost estimate of $0.0026 ($417,136/160 
million).
    These cost estimates have been updated for this final rule, given 
the differences between the final rule and NPRM in terms of the new 
CRSs being added. NHTSA observed an increased cost for most of the NPRM 
proposed CRSs that were not affected in the final rule. The estimated 
cost of a complete set of CRSs is now $4,322.40 (in 2023 dollars). 
Therefore, the cost for the one additional CRS being added is $216.12. 
The updated annual per vehicle cost is $0.0033 (($216.12 x 248 x 10)/
160 million).
    The agency believes this figure is an overestimate for the 
following reasons. NHTSA acknowledges that some manufacturers may 
purchase fewer of some CRSs (if their vehicles are equipped with air 
bag suppression systems) or more of some CRSs (if they are equipped 
with LRD air bags).\25\ Therefore, we consider 10 a high estimate for 
the number of complete sets vehicle manufacturers will purchase, 
because, based on our experience, one set can be used to certify 
several vehicle models for several years.
---------------------------------------------------------------------------

    \25\ The lineup of CRSs that a manufacturer actually purchases 
will likely vary depending on what type of advanced air bag system 
the manufacturer chooses for its vehicles. For example, CRSs can be 
more prone to damage in LRD tests, in particular rear-facing CRSs, 
due to the potential contact with the air bags, so manufacturers may 
choose to purchase more sets of certain CRSs to meet their testing 
needs. CRSs are more likely to be damaged in LRD tests because the 
air bags always deploy in an LRD test, they just deploy with less 
force. Conversely, CRSs are less likely to be damaged during 
suppression system testing because if the suppression system 
functions properly, the air bags do not deploy, and therefore cannot 
do damage to the CRS. The majority of vehicle manufacturers choose 
the suppression option for the child-sized dummies.
---------------------------------------------------------------------------

    In its August 2023 supplemental comments, the Alliance also 
commented on the increased burden of dealing with the aftermarket 
acquisition process for CRSs that are no longer widely available. 
Accordingly, the agency believes vehicle manufacturers would also save 
an unquantified amount of time and money because they will no longer 
need to acquire the existing appendix A-1 CRSs that are out of 
production through aftermarket sourcing. In addition, it is reasonable 
to assume vehicle manufacturers are testing their advanced air bag 
systems with CRSs that are not in the appendix, so it is possible that 
they already possess and have conducted testing with some of the 
proposed CRS additions, particularly the popular CRSs.

VII. Regulatory Analyses

Executive Order 12866, Executive Order 14904, Executive Order 13563, 
and DOT Regulatory Policies and Procedures

    NHTSA has considered the potential impact of this final rule under 
Executive Order 12866, Executive Order 14094, Executive Order 13563, 
DOT Order 2100.6A, and the Department of Transportation's regulatory 
policies and procedures. This final rule is not considered to be 
significant under the Department of Transportation's regulatory 
policies and procedures.\26\
---------------------------------------------------------------------------

    \26\ 44 FR 11034 (Feb. 26, 1979).
---------------------------------------------------------------------------

    This final rule makes several changes to FMVSS No. 208; 
specifically, the changes amend appendix A-1 of FMVSS No. 208, which 
lists the child restraint systems NHTSA uses in compliance testing of 
advanced air bag systems. Due to the changes in the CRSs proposed in 
the NPRM versus the CRSs being adopted as part of this final rule, the 
agency updated the costs in preparation for this final rule. The agency 
estimates that compliance with the final rule would result in a nominal 
total annual cost to all vehicle manufacturers cumulatively of $535,977 
(over ten years) for the purchase of the new CRSs. Assuming an annual 
production of 16 million vehicles (with a GVWR of 8,500 lb or less), 
the per-

[[Page 67882]]

vehicle cost is $0.0033 annually for the purchase of the new CRSs. More 
information can be found in the ``Discussion of Benefits and Costs 
Associated with the Final Rule'' section above. The minimal impacts of 
this final rule did not warrant the preparation of a regulatory 
evaluation.

Regulatory Flexibility Act

    In compliance with the Regulatory Flexibility Act, 5 U.S.C. 601 et 
seq., NHTSA has evaluated the effects of this action on small entities. 
I hereby certify that this final rule will not have a significant 
impact on a substantial number of small entities. The final rule 
affects motor vehicle manufacturers, multistage manufacturers, and 
alterers, but the entities that qualify as small businesses would not 
be significantly affected by this rulemaking because they are already 
required to comply with the advanced air bag requirements. This final 
rule would not establish new requirements, but instead would only 
adjust and update the CRSs used in FMVSS No. 208's test procedures for 
advanced air bags. The small manufacturers would continue to certify 
their vehicles as meeting the advanced air bag requirements using the 
same methods and procedures they use today, only with more current 
CRSs.

Federalism

    NHTSA has examined this final rule pursuant to E.O. 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 would 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 would 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 have a preemptive effect in two ways. First, the 
National Traffic and Motor Vehicle Safety Act contains an express 
preemption provision stating that, if NHTSA has established a standard 
for an aspect of motor vehicle or motor vehicle equipment performance a 
State may only prescribe or continue in effect a standard for that same 
aspect of performance if the State standard is identical to the Federal 
standard. 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 are generally preserved.
    NHTSA rules can also preempt State law is if complying with the 
FMVSS would render the motor vehicle manufacturers liable under State 
tort law. Because most NHTSA standards established by an FMVSS are 
minimum standards, a State common law tort cause of action that seeks 
to impose a higher standard on motor vehicle manufacturers will 
generally not be preempted. However, 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. To this end, the agency 
has examined the nature (e.g., the language and structure of the 
regulatory text) and objectives of this final rule and finds that this 
final rule, like many NHTSA rules, prescribes only a minimum safety 
standard. Accordingly, NHTSA does not intend that this final rule 
preempt state tort law that would effectively impose a higher standard 
on motor vehicle manufacturers than that established by this final 
rule. Establishment of a higher standard by means of State tort law 
would not conflict with the minimum standard finalized in this 
document. Without any conflict, there could not be any implied 
preemption of a State common law tort cause of action.

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 action would not have any significant impact on the quality of 
the human environment.

Paperwork Reduction Act

    Under the procedures established by the Paperwork Reduction Act of 
1995 (PRA) (44 U.S.C. 3501, et. seq.), a Federal agency must request 
and receive approval from the Office of Management and Budget (OMB) 
before it collects certain information from the public and 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 
rulemaking creates new information collection requirements for phase-in 
reporting and record retention requirements.
    In compliance with the requirements of the PRA, NHTSA is separately 
publishing a notice requesting comment on NHTSA's intention to request 
approval for a reinstatement with modification of a previously approved 
information collection request. Specifically, NHTSA is requesting 
reinstatement of the information collection request (ICR) with OMB 
Control No. 2127-0535 and requesting that 49 CFR part 585 be renamed 
``Phase-In Reporting Requirements.'' This ICR will be used to 
consolidate all phase-in reporting requirements that are included in 49 
CFR part 585 and was chosen because the OMB Control Number is currently 
listed in 49 CFR part 509 as being associated with information 
collections contained in part 585.
    NHTSA's ICR describes the nature of the information collections and 
their expected burden. The ICR is to request approval for two new 
information collections for mandatory phase-in reporting for vehicle 
manufacturers and related information collections.
    With this final rule NHTSA is amending Federal Motor FMVSS No. 208, 
``Occupant crash protection,'' to update the child restraint systems 
(CRSs) listed in appendix A-1 of the standard. NHTSA uses the CRSs in 
appendix A-1 to test the performance of advanced air bag suppression 
and low risk deployment systems in either suppressing or deploying the 
air bag in a low-risk manner in the presence of a CRS. The proposed 
amendments would ensure that the CRSs used by NHTSA to test advanced 
air bags are representative of the current CRS fleet and would make it 
easier for vehicle manufacturers and test laboratories to acquire CRSs 
for testing purposes.
    As part of the update to FMVSS No. 208, there will be a phase-in of 
the requirements for testing with the new CRSs listed in appendix A-1. 
This phase-in of the amendment gives vehicle manufacturers reasonable 
time

[[Page 67883]]

to certify their advanced air bag systems using the new CRSs. As with 
all phase-ins, the agency is adopting a reporting and recordkeeping 
requirement to facilitate the agency's enforcement of the standard by 
aiding NHTSA in determining whether a manufacturer has complied with 
the phase-in requirements during the phase-in period. These 
requirements are found in 49 CFR part 585, ``Phase-In Reporting 
Requirements.'' The reporting and recordkeeping requirements require 
that manufacturers submit an annual production report to NHTSA that 
includes the number of vehicles manufactured in the current production 
year and the production of complying vehicles and that they retain 
records of compliance with the phase-in requirements for five years. 
NHTSA estimates this collection will impact 22 manufacturers each year 
and will have a total annual burden of approximately 22 hours and $0.

Unfunded Mandates Reform Act (UMRA)

    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 annually for inflation, with base year 
of 1995). UMRA also requires an agency issuing an NPRM or final rule 
subject to the Act to select the ``least costly, most cost-effective or 
least burdensome alternative that achieves the objectives of the 
rule.'' This final rule would not result in a Federal mandate that will 
likely 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 annually for inflation, with base year 
of 1995).

Executive Order 12778 (Civil Justice Reform)

    When promulgating a regulation, agencies are required under 
Executive Order 12988 to 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 and general 
draftsmanship of regulations.
    Pursuant to this Order, NHTSA notes as follows. The preemptive 
effect of this final rule is discussed above. NHTSA notes further that 
there is no requirement that an individual submit a petition for 
reconsideration or pursue other administrative proceedings before they 
may file suit in court.

National Technology Transfer and Advancement Act

    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 the International 
Organization for Standardization (ISO) and the Society of Automotive 
Engineers (SAE). The NTTAA directs this agency to provide Congress, 
through OMB, explanations when we decide not to use available and 
applicable voluntary consensus standards. There are no voluntary 
consensus standards developed by voluntary consensus standards bodies 
pertaining to this final rule.

Plain Language Requirement

    Executive Order 12866 requires each agency to write all rules in 
plain language. Application of the principles of plain language 
includes consideration of the following questions:
     Have we organized the material to suit the public's needs?
     Are the requirements in the rule clearly stated?
     Does the rule contain technical language or jargon that 
isn't clear?
     Would a different format (grouping and order of sections, 
use of headings, paragraphing) make the rule easier to understand?
     Would more (but shorter) sections be better?
     Could we improve clarity by adding tables, lists, or 
diagrams?
     What else could we do to make the rule easier to 
understand?
    NHTSA has considered these questions and attempted to use plain 
language in promulgating this final rule. Please inform the agency if 
you can suggest how NHTSA can improve its use of plain language.

Regulatory 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. The RIN 
contained in the heading at the beginning of this notice may be used to 
find this action in the Unified Agenda.

Privacy Act

    In accordance with 5 U.S.C. 553(c), DOT solicits comments from the 
public to better inform its decision-making process. DOT posts these 
comments, without edit, including any personal information the 
commenter provides, to www.regulations.gov, as described in the system 
of records notice (DOT/ALL-14 FDMS), which can be reviewed at
