Federal Motor Vehicle Safety Standard No. 213a; Child Restraint 
Systems--Side Impact Protection; Federal Motor Vehicle Safety Standard 
No. 213; Child Restraint Systems, Federal Motor Vehicle Safety Standard 
No. 213b; Child Restraint Systems

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

ACTION: Notice of proposed rulemaking; Grant of petitions for 
rulemaking and other proposals.

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

SUMMARY: This document proposes amendments to the safety standards for 
child restraint systems (CRSs). NHTSA is proposing to amend FMVSS No. 
213a, ``Child restraint systems--side impact protection,'' to exempt 
school bus CRSs from the standard's requirements as long as they meet 
specified labeling requirements; to delay the compliance date from June 
30, 2025 to December 5, 2026; to provide that the Child Restraint Air 
Bag Interaction twelve-month-old (CRABI-12MO) test dummy will not be 
used to test forward-facing CRSs; and to amend the positioning 
procedures for that dummy. The first two of these amendments are in 
response to petitions from CRS manufacturers. NHTSA is also proposing 
to amend FMVSS No. 213, ``Child restraint systems'' and FMVSS No. 213b, 
``Child restraint systems; Mandatory applicability beginning December 
5, 2026,'' to exclude school bus CRSs from the requirements to provide 
attachments for connection to the vehicle's child restraint anchorage 
system and to change certain labeling requirements to reflect how 
school bus child restraints are used.

DATES: Comments must be submitted no later than June 30, 2025.
    Proposed Effective date: The effective date would be the date of 
publication of the final rule in the Federal Register.

Proposed Regulatory Text

I. Executive Summary

    This document proposes amendments to three different safety 
standards: FMVSS No. 213, ``Child restraint systems; Applicable unless 
a vehicle or child restraint system is certified to Sec.  571.213b''; 
FMVSS No. 213b, ``Child restraint systems; Mandatory applicability 
beginning December 5, 2026''; and FMVSS No. 213a, ``Child restraint 
systems--side impact protection.'' FMVSS Nos. 213, 213a, and 213b set 
out most of the agency's safety requirements for child restraint 
systems (CRS).
    This document proposes four amendments to the side impact standard 
(FMVSS No. 213a):
     Exempt school bus CRSs from the side impact requirements 
in FMVSS No. 213a. The December 5, 2023 final rule updating FMVSS No. 
213 and establishing FMVSS No. 213b for frontal impact requirements, 
amended the standards to permit more types of add-on CRSs specially 
designed for

[[Page 23010]]

exclusive use on school buses, that were not permitted at the time, 
with the intent to facilitate the availability of these CRSs that are 
only used on school buses. Because these CRSs are designed to install 
on school bus seats with seat back mounts, their construction does not 
provide rigid side structures (similar to harnesses) and because the 
side impact environment in school buses is different from the side 
impact environment simulated by the FMVSS No. 213a standard, the agency 
is proposing to exempt school bus CRSs from FMVSS No. 213a. This 
proposal is NHTSA's action on a grant of petitions for rulemaking from 
IMMI and BESI, Inc.
     Delay the compliance date of FMVSS No. 213a from June 30, 
2025 to December 5, 2026. The agency received a petition for rulemaking 
from a group of CRS manufacturers which requested a delay on the FMVSS 
No. 213a compliance date to ``prevent market disruption resulting in 
reduced availability of CRSs'' and due to ``limited availability of 
compliance lab sled time'' that is needed for the development and 
certification of their products. This proposal is NHTSA's action on a 
grant of petitions for rulemaking from a group of CRS manufacturers.
     Provide that the CRABI-12MO test dummy will not be used to 
test forward-facing CRSs for side impact requirements in FMVSS No. 
213a. The frontal update standard (FMVSS No. 213b) requires that 
forward-facing CRSs must have a minimum recommended child weight of 12 
kg (26.5 lbs.). Since the CRABI-12MO dummy only weighs 10 kg (22 lb.), 
the standard excluded testing forward-facing CRSs with the CRABI-12MO 
dummy because the dummy would be too small for the CRS design. To 
maintain consistency between standards, the agency proposes to exclude 
testing forward-facing CRSs from side impact requirements in FMVSS No. 
213a.
     Amend the positioning procedures for the CRABI-12MO dummy 
to reflect that the dummy would no longer be tested with forward-facing 
CRSs.
    NHTSA is also proposing to amend FMVSS No. 213, ``Child restraint 
systems'' and FMVSS No. 213b, ``Child restraint systems; Mandatory 
applicability beginning December 5, 2026,'' to exclude school bus CRSs 
from the requirements to provide attachments for connection to the 
vehicle's child restraint anchorage system. Generally, school bus CRSs 
have a seat back mounting installation method that is necessary for 
school bus seats. It was not the intent of the agency to apply the 
requirement for child restraint anchorage system attachments to the 
school bus CRSs when the agency finalized the frontal impact update 
final rule. Therefore, NHTSA proposes to add school bus CRSs to the 
exclusion list in both FMVSS No. 213 S5.9(a) and FMVSS No. 213b 
S5.9(a). The agency also proposes to amend S5.5.2(g)(1)(ii) in FMVSS 
Nos. 213 and 213b which require a labeling statement regarding how to 
secure the CRS to the vehicle to be consistent with the seat back mount 
required in school bus CRSs.

II. Background

    This document proposes amendments to three different safety 
standards: FMVSS No. 213, ``Child restraint systems; Applicable unless 
a vehicle or child restraint system is certified to Sec.  571.213b''; 
FMVSS No. 213b, ``Child restraint systems; Mandatory applicability 
beginning December 5, 2026''; and FMVSS No. 213a, ``Child restraint 
systems--side impact protection.'' FMVSS Nos. 213, 213a, and 213b set 
out most of the agency's safety requirements for child restraint 
systems (CRS). Each of these three standards has either been 
established or updated in final rules over the past 3 years. Below we 
provide some brief background information on the recent regulatory 
history for these standards to provide context for the proposed 
amendments.

FMVSS Nos. 213 and 213b--The Frontal Impact Standards

    FMVSS No. 213 is the original CRS standard, which was established 
in the 1970s.\1\ FMVSS No. 213 sets out a number of requirements for 
CRSs, but perhaps the most significant portion of FMVSS No. 213 is its 
requirements for frontal impact protection. The standard sets out a 
test procedure that involves a sled bench and a crash pulse that 
simulates a frontal collision. CRSs must meet certain minimum 
requirements during these crash tests (e.g., maximum head and knee 
excursions of a restrained child-size test dummy, head and chest injury 
criteria).
---------------------------------------------------------------------------

    \1\ The standard has been updated throughout the years by, among 
other things, incorporating new child dummies, updating the 
standard's test seat assembly, and requiring CRSs to provide means 
to attach the CRS to the vehicle child restraint anchorage system.
---------------------------------------------------------------------------

    In 2020 NHTSA published an NPRM that proposed sweeping updates to 
the frontal impact standard,\2\ and in 2023 NHTSA published a final 
rule.\3\ In implementing these changes, NHTSA created a new standard, 
FMVSS No. 213b. FMVSS No. 213 applies to CRSs manufactured before 
December 5, 2026, and FMVSS No. 213b applies to child restraint systems 
manufactured on or after December 5, 2026. FMVSS No. 213 therefore 
sunsets on December 5, 2026.
---------------------------------------------------------------------------

    \2\ 85 FR 69388 (Nov. 2, 2020).
    \3\ 88 FR 84514 (Dec. 5, 2023).
---------------------------------------------------------------------------

    NHTSA received two petitions for reconsideration to the 2023 
frontal impact final rule (from Juvenile Products Manufacturers 
Association (JPMA) and Evenflo). Both petitions were timely filed 
within 45 days after each respective rule was published. The petitions 
concerned a variety of issues. For example, JPMA requested removing 
testing CRSs installed with lap belt only in frontal sled test, and 
guidance on the new registration information for consumers, while 
Evenflo requested the deletion of duplicative language.
    NHTSA responded to these petitions in a final rule published on 
October 9, 2024.\4\ (This final rule also responded to petitions for 
reconsideration received on the side impact final rule, which is 
discussed in the immediately following section.)

FMVSS No. 213a--The Side Impact Standard

    The Moving Ahead for Progress in the 21st Century Act (``MAP-21''), 
enacted in 2012, directed NHTSA to initiate a rulemaking to improve 
safety for children involved in side impact crashes.\5\ In response to 
this mandate, in 2014 NHTSA published an NPRM proposing side impact 
protection requirements for CRSs under a new standard, FMVSS No. 
213a.\6\ NHTSA finalized the rule in 2022.\7\ The final rule 
established, among other things, performance requirements that must be 
met in a test simulating the acceleration pulse and door intrusion that 
occurs in a real-world side impact. The compliance date of the final 
rule is June 30, 2025.

    NHTSA received two petitions for reconsideration to the 2022 side 
impact final rule (from Columbus Trading Partners USA, Inc (Cybex 
products distributor) and Evenflo). Both petitions were timely filed 
within 45 days after the final rule was published and concerned a 
variety of issues. For example, Cybex requested NHTSA clarify how 
fixed, adjustable, and configurable side impact technologies will be 
tested in future annual compliance test programs. NHTSA responded to 
these petitions in the same notice published on October 9, 2024 that 
responded to the petitions for

[[Page 23011]]

reconsideration of the 2023 frontal impact final rule.\8\
---------------------------------------------------------------------------

    \8\ See supra note 4.
---------------------------------------------------------------------------

Petitions for Reconsideration and Rulemaking Subsequent to the October 
2024 Final Rule

    After publishing the October 2024 final rule responding to the 
petitions for reconsideration of the frontal impact and side impact 
rulemakings, NHTSA received three additional petitions for 
reconsideration, as well as a related petition for rulemaking. The 
petitions for reconsideration were from IMMI (dated November 18, 2024); 
BESI, Inc. (dated November 22, 2024); and a group of CRS manufacturers 
\9\ (dated November 24, 2024). IMMI and BESI requested that NHTSA 
exempt school bus CRSs that do not meet the regulatory definition of 
``harness'' in FMVSS Nos. 213a from the side impact requirements. IMMI 
also submitted a petition for rulemaking on January 8, 2025 that 
highlighted the same issues raised in its petition for reconsideration. 
The petition for reconsideration from the group of CRS manufacturers 
requested a delay of the June 30, 2025, compliance date of the side 
impact standard to prevent ``significant market disruption resulting 
from a reduced availability of child restraint systems and higher costs 
than necessary for those that are available.''
---------------------------------------------------------------------------

    \9\ BabyTrend, Babyark, DECA Consulting, Diono, Doona, 
KidsEmbrace, Peg Parego, and Safe Traffic System.
---------------------------------------------------------------------------

    Because the petitions do not request reconsideration of any 
amendments made in the October 2024 final rule,\10\ and in accordance 
with NHTSA's regulations, the agency has decided to treat the three 
petitions for reconsideration as petitions for rulemaking. The agency 
has informed all petitioners of this decision. NHTSA has decided to 
grant all three of these petitions for rulemaking and is publishing 
this document in furtherance of that grant.
---------------------------------------------------------------------------

    \10\ The petition from the group of CRS manufacturers to delay 
the compliance date for the side impact requirements is outside the 
scope of the October 2024 final rule because that final rule only 
discussed compliance dates in the context of amending compliance 
dates for the frontal impact update, not the side impact final 
standard.
---------------------------------------------------------------------------

III. Proposed Amendments to Side Impact Requirements (FMVSS No. 213a)

A. Exempt School Bus CRSs From the Side Impact Requirements

    The frontal and side impact standards recognize different 
categories of CRSs, each of which must meet different requirements 
using different required methods of installation. For instance, the 
most common category of CRS is an add-on child restraint system, which 
is defined as any portable child restraint system. These are the types 
of restraints that come to mind when someone colloquially refers to a 
CRS as a ``car seat.'' Another category of CRS with specific 
requirements is a harness, which the standards define as a CRS that 
``consists primarily of flexible material, such as straps, webbing or 
similar material, and does not include a rigid seating structure for 
the child.'' Harnesses designed for use in vehicles are generally 
required to provide a means of installation with a vehicle lap 
belt.\11\ Since 2004, however, FMVSS No. 213 had specifically exempted 
harnesses manufactured for exclusive use on school buses from this 
requirement as long as the harness includes a warning label.\12\ School 
bus harnesses attach to school bus seats backs without needing a seat 
belt assembly to secure this harness type to the seat. Thus, this type 
of harness can be used on large school buses that are not equipped with 
seat belts, which is the majority of school buses. School bus harnesses 
were exempted from the seat belt installation requirement because many 
school districts and school bus operators need a product with a seat 
back mount to transport preschoolers, children who need help sitting 
upright, and children who need to be physically restrained because of 
physical or behavioral needs.\13\ Harnesses manufactured for use on 
school buses that are properly labeled are also exempt from some of the 
standard's other requirements (e.g., means of installation to lower 
anchors). Harnesses manufactured for use on school buses were otherwise 
subject to the standard, importantly including the sled test 
requirements.
---------------------------------------------------------------------------

    \11\ They may be tested with a tether if provided with the CRS.
    \12\ 69 FR 10928 (Mar. 9, 2004 (final rule). The warning label 
is required to inform users that the harness may be used only on 
school bus seats, and that the entire seat directly behind the child 
wearing the seat-mounted harness must be either unoccupied or 
occupied by restrained passengers.
    \13\ 69 FR 10928, March 9, 2004.
---------------------------------------------------------------------------

    Around the time of the 2004 final rule, restraint manufacturers 
began introducing a new type of child restraint for exclusive use in a 
school bus--one that utilized a harness consisting primarily of 
flexible material for the upper torso, together with a rigid base.\14\ 
Because such a device did not primarily consist of flexible material, 
it was not categorized as a ``harness'' under the FMVSS No. 213 (the 
only CRS standard at the time), and therefore did not qualify for the 
exemptions that were available for school bus harnesses.\15\
---------------------------------------------------------------------------

    \14\ IMMI comments to 2014 side impact NPRM. Docket No. NHTSA-
2014-0012-0023: ``The STAR utilizes a harness type restraint 
consisting primarily of flexible material for the upper torso of the 
child that is integrated into a rigid lower base booster 
structure.''
    \15\ NHTSA letter to IMMI, September 21, 2016: https://www.nhtsa.gov/interpretations/14-001678-immi-star-crs.
---------------------------------------------------------------------------

    In its comments to the 2014 side impact NPRM, IMMI raised this 
issue with respect to both FMVSS No. 213 and the proposed FMVSS No. 
213a.\16\ The side impact NPRM proposed to entirely exempt harnesses 
and car beds from the standard. NHTSA did not apply the side impact 
standard to harnesses and car beds, which are not designed to protect 
children during a side impact collision, because ``of practicability 
concerns about the ability of the harness to meet the proposed 
requirements and because harnesses serve a need in certain 
populations.'' \17\ In its comment, IMMI described one of its child 
restraints for exclusive use in a school bus as a hybrid design of 
harness and child seat. It noted that while the side impact NPRM 
excluded harnesses and car beds from its requirements, it did not 
clearly encompass CRSs for exclusive use in a school bus with rigid 
elements, such as IMMI's CRS. This inconsistency was consequential 
because this type of hybrid school bus CRS is not designed to protect 
children in a side impact collision, and so would not comply with the 
standard. IMMI suggested a few different options for providing this 
flexibility to CRS for exclusive use in school bus manufacturers, 
including by clarifying the regulatory text in the CRS standards. 
However, the 2022 side impact final rule did not account for this and 
therefore did not exempt school bus child restraints that are not 
harnesses \18\ from the standard.
---------------------------------------------------------------------------

    \16\ IMMI comments to 2014 side impact NPRM: Docket No. NHTSA-
2014-0012-0023: ``The incorporation of a hybrid harness restraint 
consisting primarily of flexible material for the upper torso of the 
child that is attached to that rigid lower base booster structure 
offers the users with a unique means of attachment and 
portability.''
    \17\ 79 FR 4570, 4576 (Jan. 28, 2014) (side impact NPRM). See S3 
(``This standard applies to add-on child restraint systems . . . 
except for car beds and harnesses.'')
    \18\ The school bus CRS category had not yet been introduced 
into FMVSS No. 213.
---------------------------------------------------------------------------

    On the other hand, the 2023 frontal upgrade final rule did amend 
the frontal impact requirements to extend the exemption for school bus 
child restraints harnesses to this type of hybrid school bus restraint 
IMMI referred to. In response to the NPRM, IMMI and other commenters 
supported

[[Page 23012]]

this approach. Accordingly, the 2023 frontal impact final rule 
included, among other things, a definition of ``school bus child 
restraint system'' that was design-neutral and specific to school bus 
seat usage. It defined school bus child restraint system as a child 
restraint system (including, but not limited to, harnesses) sold for 
exclusive use on school bus seats with a label conforming with 
S5.3.1(b) of FMVSS Nos. 213 or 213b. School bus child restraints that 
are not harnesses were consequently now required to provide means of 
installation with a seat back and/or seat back mount and not required 
to provide means of installation with a vehicle seat belt and/or to the 
lower anchorages or the child restraint anchorage system, as long as it 
is appropriately labeled. However, while NHTSA amended the frontal 
impact standards to account for this type of partially rigid school bus 
child restraint, it did not similarly amend the side impact 
requirements. The result is that while school bus CRSs are exempted 
from some of the requirements in the frontal impact standards so that 
they are able to comply with it, they are not exempted at all from the 
side impact standard, which they are not able to comply with because 
they are not designed to provide protection in a side impact.
    IMMI and BESI requested that NHTSA exempt school bus CRSs that do 
not meet the regulatory definition of ``harness'' in FMVSS Nos. 213a 
from the side impact requirements. IMMI noted that it had commented on 
this issue in response to the 2014 side impact NPRM, but that the final 
rule had not addressed this issue. It also noted meetings that it had 
had with NHTSA about this issue. It stated that after the 2022 side 
impact final rule was published, IMMI had met with NHTSA and NHTSA 
informed it that the matter of school bus child restraints would be 
handled in a future rulemaking. IMMI commented that, nevertheless, the 
October 2024 final rule also did not address this issue. IMMI also 
described its school bus CRS product, the Student Transportation Add-on 
Restraint (STAR), which consists of a harness attached to a rigid seat 
base that provides fixed anchorage points for the harness's lap belt 
and crotch strap. It explained that because the purpose of the STAR is 
to safely secure the child to the school bus seat, there is no shell 
component in this restraint to provide protection for side impact 
collisions. IMMI stated that ``due to the nature of its design, [STAR] 
is not capable of meeting the newly established side impact 
requirements of FMVSS 213a.'' It also explained what it viewed as the 
advantages of the product, and noted that NHTSA has included this type 
of CRS in its training materials. IMMI and BESI stated that unless 
school bus CRSs are excluded from side impact requirements, they will 
have to stop production of these CRSs (for the U.S. market) and that 
this would affect Head Start programs which require the use of child 
restraint systems in school bus transportation of their students. IMMI 
and BESI therefore requested that NHTSA amend FMVSS No. 213a so that 
this type of restraint would not be subject to the side impact 
protection standard.
    NHTSA has tentatively concluded that the requests from IMMI and 
BESI have merit. While the side impact standard explicitly exempts 
harnesses and car beds, which do not need to be certified to the 
standard, this exemption does not include school bus child restraints 
that are not harnesses. Accordingly, under the current CRS regulatory 
framework, there is a path for school bus CRSs--whether they qualify as 
harnesses or not--to be compliant under the frontal impact standards, 
but there is not a path for those school bus CRSs that are not 
harnesses to be compliant under FMVSS No. 213a. Similar to harnesses, 
NHTSA believes school bus CRSs should be excluded because of 
practicability concerns about the ability of the school bus CRS to meet 
the proposed requirements and because school bus CRSs serve a niche 
market where the needs cannot be met by any other type of CRS. NHTSA 
also recognizes that the side impact crash environment of a school bus 
is significantly different from the simulated side impact test in FMVSS 
No. 213a. Accordingly, the agency would like to correct this 
inconsistency in the CRS standards, and is therefore proposing to 
explicitly exempt all school bus CRSs from applicability under the side 
impact standard. NHTSA seeks comment on this proposal.

B. Exclude the CRABI-12MO Test Dummy From Testing Forward-Facing CRSs 
and Make Corresponding Amendments to the Dummy Positioning Procedures

    Child restraint systems must meet the performance requirements in 
FMVSS Nos. 213, 213a, and 213b when dynamically tested with 
anthropomorphic test devices (test dummies). Each child restraint 
system must meet the requirements when oriented in each direction the 
CRS is designed to be used in (i.e., forward, rearward).
    The 2022 side impact final rule expanded the performance 
requirements for child restraint systems (CRSs) by adopting a side 
impact test that requires that CRSs meet specified performance 
requirements when tested with two different dummies: the well-
established 12-month-old child test dummy (CRABI-12MO) \19\ dummy and a 
newer side impact test dummy representing a 3-year-old child (the 
Q3s).\20\ NHTSA explained, in the final rule, that it was choosing to 
limit testing for the side impact requirements to these two dummies, as 
opposed to a broader range of dummies representing children of a wider 
range of ages. One reason NHTSA cited was there is no side impact dummy 
representative of children larger than those represented by the Q3s 
that can reasonably be used to test CRSs for children above 18 kg (40 
lb) to the dynamic side impact requirements.\21\

Alpha Version.

Dummy.
    \21\ See 79 FR 4570, 4573 (Jan. 28, 2014) (side impact NPRM).
---------------------------------------------------------------------------

    The CRABI-12MO represents a twelve-month-old child and weighs 10 kg 
(22 lb). FMVSS No. 213a uses the CRABI-12MO to measure the containment 
capability of the CRS (the ability to prevent the dummy's head from 
making contact with the intruding door of the sled assembly). The 
standard specifies the CRABI-12MO for testing CRSs that are recommended 
by their manufacturer for use by children in a specified mass range 
that includes any children having a mass greater than 5 kg (11 lb) but 
not greater than 13.6 kg (30 lb), or by children in a specified height 
range that includes any children whose height is greater than 650 mm 
but not greater than 850 mm.
    The Q3s represents a 3-year-old and weighs 14.5 kg (32 lb). The 
standard specifies the Q3s for testing CRSs that are recommended by 
their manufacturer for use by children having a mass greater than 13.6 
kg (30 lb) but not greater than 18 kg (40 lb), or by children whose 
height is greater than 870 mm but not greater than 1100 mm. FMVSS No. 
213a uses the Q3s to evaluate the crash forces experienced by a 
restrained child and specifies injury criteria (expressed in terms of a 
head injury criterion (HIC) and chest deflection) that may not be 
exceeded. These criteria allow a quantitative evaluation of the 
effectiveness of the CRS to prevent or attenuate head and chest impact 
with the intruding door.
    The weight and height ranges for selecting either the CRABI-12MO 
and the Q3s were specifically chosen to

[[Page 23013]]

mirror the weight ranges specified for testing CRSs to the frontal 
impact requirements in FMVSS Nos. 213 and 213b for CRSs with 
manufacturer recommended weights between 5 kg (11 lb) and 18 kg (40 
lb).\22\ Specifically, the frontal impact standards specify testing 
CRSs recommended for children weighing 5 kg (11 lb) to 13.6 kg (30 lb), 
and specify a different 3-year-old dummy (the HIII-3yo) for testing 
CRSs recommended for children weighing 13.6 kg (30 lb) to 18 kg (40 
lb). NHTSA had a variety of reasons for choosing these cutoffs; one of 
them was consistency between the front and side impact 
requirements.\23\
---------------------------------------------------------------------------

    \22\ 87 FR 39234, 39290 (June 30, 2022) (side impact final rule) 
(``These weight categories were designed to be consistent with the 
criteria used in the current FMVSS No. 213 in determining the test 
dummies that are used to test child restraints to the standard's 
frontal test requirements.'').
    \23\ 88 FR 84514, 84516 (December 5, 2023) (frontal update final 
rule) (``This final rule makes the following changes to simplify and 
make more representative the agency's use of test dummies in 
compliance tests (S7) . . . The purpose of these amendments is to 
heighten the assessment of CRS performance in protecting a child 
occupant.'').
---------------------------------------------------------------------------

    This proposal for FMVSS No. 213a concerns one aspect of these dummy 
specifications for which the specifications in FMVSS No. 213a do not 
mirror those in FMVSS Nos. 213 and 213b. In its comments to the frontal 
impact upgrade NPRM, Evenflo pointed out a potential inconsistency in 
the testing for which the CRABI-12MO was specified.\24\ Evenflo noted 
that while FMVSS No. 213 requires that ``manufacturers shall not 
recommend forward-facing use for child restraint systems with internal 
harnesses for children of masses less than 12 kg (26.5 lb)'' \25\, the 
front impact proposal specified the CRABI-12MO (which weighs 10 kg (22 
lb)) for testing CRSs recommended for use with children weighing more 
than 10 kg (22 lb) and not more than 13.6 kg (30 lb). Thus, it proposed 
using the CRABI-12MO to test CRSs that manufacturers would not have 
been permitted to recommend for forward-facing use for children 
weighing the same as the dummy.\26\ In response to this comment, NHTSA 
added language to the finalized standard providing that ``the CRABI 
12MO dummy is not used to test a forward-facing child restraint 
system'' in this weight/height range. The final rule preamble also 
noted that ``this change has implications for the agency's use of the 
CRABI-12MO in FMVSS No. 213a (Side Impact Protection) compliance tests 
. . . NHTSA plans to issue an NPRM to propose a conforming amendment to 
FMVSS No. 213a that the CRABI-12MO would not be used forward-facing in 
the side impact test for CRSs labeled with a turnaround weight of 12 kg 
(26.5 lb).'' \27\
---------------------------------------------------------------------------

    \24\ NHTSA did not receive any comments to the 2014 side impact 
NPRM raising this issue.
    \25\ FMVSS No. 213, S5.5.2.(f)(2); FMVSS No. 213, S5.5.2(f).
    \26\ It would be permissible for manufacturers to recommend a 
seat for forward-facing use for a subset of children weighing 
between 10 kg (22 lb) and 13.6 kg (30 lb)--namely, children weighing 
less than 12 kg (26.5)--but NHTSA has decided not to specify the 
CRABI-12MO for testing CRS designated for forward-facing use for 
such children in order to simplify the requirements.
    \27\ 88 FR 84514, 845551 (Dec. 5, 2023) (frontal impact upgrade 
final rule).
---------------------------------------------------------------------------

    NHTSA is now proposing to amend the side impact standard to include 
this language providing that the CRABI-12MO dummy will not be used to 
test a forward-facing child restraint system recommended for use by 
children in a specified mass range that includes any children having a 
mass greater than 5 kg (11 lb) but not greater than 13.6 kg (30 lb), or 
by children in a specified height range that includes any children 
whose height is greater than 650 millimeters but not greater than 870 
millimeters. NHTSA believes it would make sense for CRSs to be tested 
with the same test dummies in both the frontal impact and side impact 
tests to minimize burden on CRS manufacturers. NHTSA also believes that 
a requirement to test a CRS in a configuration that is not allowed is 
unnecessary and burdensome as CRS manufacturers might have to design 
their CRS models to accommodate a dummy representing a child that is 
not recommended for that specific CRS and/or CRS configuration.
    The agency also proposes to delete paragraphs S9.1(c) and (d) in 
FMVSS No. 213a because those sections contain positioning information 
relating to testing forward-facing CRSs with a CRABI dummy which would 
no longer be relevant. NHTSA is also proposing to amend S9.1(b). 
Currently that section describes how to position the CRABI dummy in a 
``forward-facing'' child restraint system. Instead, S9.1(b) should 
indicate how to position the CRABI dummy in CRSs used rear-facing with 
the same procedure that is used in FMVSS No. 213b, for consistency 
between the standards and for completeness of the dummy positioning 
procedure. NHTSA seeks comment on this proposal.

C. Delay the Compliance Date From June 30, 2025 to December 5, 2026

    The petition for reconsideration from the group of CRS 
manufacturers \28\ requested a delay of the June 30, 2025, compliance 
date of the side impact standard to prevent ``significant market 
disruption resulting from a reduced availability of child restraint 
systems and higher costs than necessary for those that are available.'' 
The petitioners argued that the extension is needed because of 
``inconsistent results within individual labs and lab to lab 
variation,'' and the limited ``availability of compliance lab sled 
time'' to develop their products to certify compliance with the new 
standard. The petitioners suggested that the agency consider moving the 
FMVSS No. 213a compliance date to December 5, 2026, to match the 
compliance date of FMVSS No. 213b.
---------------------------------------------------------------------------

    \28\ BabyTrend, Babyark, DECA Consulting, Diono, Doona, 
KidsEmbrace, Peg Perego, and Safe Traffic System.
---------------------------------------------------------------------------

    The agency has tentatively decided that this petition has merit and 
is proposing to delay the compliance date of FMVSS No. 213a to December 
5, 2026. The side impact standard is new and broadly applicable, 
meaning CRS manufacturers must certify most, if not all, of their 
products to a variety of new requirements. The agency understands this 
takes a significant amount of testing for both research, development, 
and certification purposes. Although the agency believes there are 
significant safety benefits associated with the side impact standard, 
manufacturers potentially having to stop manufacturing certain CRSs 
because they cannot comply with the side impact standard by June 30, 
2025 would also create potential child safety issues due to reduced 
availability of CRSs for purchase. The agency believes that it would be 
prudent to give manufacturers more time to test and certify their 
applicable products to the side impact standard to ensure currently 
compliant CRSs remain available on the market. This proposal would 
still allow for the option of early compliance with the side impact 
standard.\29\
---------------------------------------------------------------------------

    \29\ Manufacturers who certify their products to the side impact 
standard early may be subject to the agency's compliance testing.
---------------------------------------------------------------------------

    A compliance date of December 5, 2026 would coincide with the 
compliance date for many of the requirements of the frontal impact 
update standard. The agency believes the extra 15 months should be 
sufficient time for manufacturers to complete testing of their products 
for compliance with the side impact standard. Additionally, we believe 
it would ease the burden on manufacturers to have the frontal impact 
update and side impact compliance dates align, as manufacturers would 
have one target date for certification. Accordingly, the agency 
proposes to delay the compliance date of FMVSS No. 213a to

[[Page 23014]]

December 5, 2026. NHTSA seeks comment on this proposal.

IV. Proposed Amendments To Front Impact Requirements (FMVSS Nos. 213 
and 213b)

    As discussed above, the frontal impact update final rule added a 
definition of ``school bus child restraint system.'' NHTSA explained in 
the frontal impact update final rule that FMVSS No. 213 has special 
accommodations for harnesses manufactured exclusively for use on school 
bus seats. These accommodations meet the need that many school 
districts and school bus operators have for a product with a seat back 
mount to transport children who need help sitting upright and remaining 
safely in their seat. The seat back attachment hardware of these 
specialized school bus harnesses does not use a seat belt to attach to 
the bus seat. This attachment configuration permits use of these 
harnesses in the significant population of large school buses that are 
without seat belts.
    While the agency made several modifications to FMVSS Nos. 213 and 
213b to create a new CRS category (school bus CRSs) in the frontal 
impact update final rule, the agency did not exempt these CRSs from the 
requirements of S5.9(a). This section requires CRS to have components 
permanently attached to the CRS that enable the restraint to be 
fastened to a vehicle's child restraint anchorages. Paragraph S5.9(a) 
currently excludes car beds, harness, and belt positioning seat from 
having these attachments. The agency did not intend to require lower 
anchorage attachments for school bus CRSs as these types of CRSs are 
expected to have a seat back mount to install them on the school bus 
seat. In other words, school bus CRSs are generally not designed for 
installation in other types of motor vehicles, and the agency sees no 
reason to require school bus CRSs to meet requirements adopted to 
ensure certain CRSs can be installed in other types of motor vehicles. 
Additionally, under the new requirements for school bus CRSs in the 
frontal impact update standards, school bus CRSs must have a label 
explaining that the CRS is for use exclusively in school buses, meaning 
the agency thinks there is very little risk a consumer would try to 
install a school bus CRS in a motor vehicle. Accordingly, this NPRM 
proposes to exclude ``school bus CRSs'' from the S5.9(a) requirements 
in FMVSS Nos. 213 and 213b. The agency also proposes to amend 
S5.5.2(g)(1)(ii) in FMVSS Nos. 213 and 213b which require a labeling 
statement regarding how to secure the CRS to the vehicle. Because the 
requirement lists the ``child restraint anchorage system'' or ``vehicle 
belt'' as methods to attach the CRS to the vehicle, NHTSA proposes to 
add a requirement specific for school bus CRSs that would indicate the 
seat back mount in the statement as the method for attaching the CRS to 
the vehicle instead of the ``child restraint anchorage system or 
vehicle belt'' because those methods are not used when using school bus 
CRSs. NHTSA seeks comment on this proposal.

V. Costs and Benefits

    Due to the change in compliance date, both benefits and costs, 
which are ultimately borne by consumers, associated with meeting the 
requirement of FMVSS No. 213a will be delayed. Additionally, there may 
be a cost savings associated with avoiding a market disruption as 
manufacturers have indicated to the agency that they may have to stop 
manufacturing certain CRSs that they cannot certify to the new FMVSS 
No. 213a requirements by June 30, 2025.\30\ Delaying the compliance 
date would ensure CRS manufacturers can continue to manufacture 
currently compliant CRSs while they work to certify compliance with the 
new side impact requirements. NHTSA estimates that the cost savings to 
consumers resulting from a delay in the compliance date from June 30, 
2025 to December 5, 2026 is about $10.58 million.
---------------------------------------------------------------------------

    \30\ The FMVSS No. 213a final regulatory impact analysis (FRIA) 
estimates an annual cost of $7.37 million to meet FMVSS No. 213a 
requirements. By delaying the compliance date from June 30, 2025 to 
December 5, 2026 would result in cost savings to society by $10.58 
million. The full analysis on the compliance date delay cost savings 
will be docketed along with this NPRM.
---------------------------------------------------------------------------

    There are no additional benefits expected from exempting school bus 
child restraint systems from side impact protection requirements and 
lower anchorages attachment requirements since these products have been 
in the market. Similar to the potential delay cost savings discussed 
above, exempting school bus CRSs from the side impact requirements may 
result in a cost savings for manufacturers, as it is likely that school 
bus CRS manufacturers would have to stop manufacturing school bus CRSs 
that cannot comply with FMVSS No. 213a by June 30, 2025. Exempting 
school bus CRSs from compliance with FMVSS No. 213a would ensure that 
school bus CRS manufacturers can continue to manufacture their products 
after June 30, 2025.
    Removing the requirement to test CRSs in forward facing mode with 
the CRABI dummy for side impact protection, would have no benefits but 
would reduce yearly testing costs by $1,290,000.\31\
---------------------------------------------------------------------------

    \31\ There are currently 48 convertible CRS models, 60 all-in-
one CRS models and 21 combination CRS models. Each forward-facing 
convertible, combination and all-in-one CRS would no longer be 
tested using the CRABI-12MO in a forward-facing configuration. The 
cost of a side impact sled test is estimated at $5,000. Therefore, 
the temporary additional test cost is estimated to be $1,290,000 
(129 CRS Models x $5000 x 2 test installation configurations with 
CRABI-12MO in forward-facing mode).
---------------------------------------------------------------------------

    Finally, exempting school bus CRSs from compliance with the FMVSS 
Nos. 213 and 213b lower anchorage attachment requirements will likely 
result in a cost savings for manufacturers. If the agency does not 
adopt this amendment, school bus CRSs could comply with FMVSS Nos. 213 
and 213b, but would have to be equipped with hardware that would allow 
the school bus CRSs to attach to the lower anchors in a motor vehicle 
other than a school bus. This would be unnecessary, as school bus CRSs 
are not designed for use in other types of motor vehicles. 
Additionally, FMVSS Nos. 213 and 213b have a requirement that school 
bus CRSs must be labeled and inform the consumer that school bus CRSs 
are only for use in school buses. Accordingly, the agency believes 
there would be some cost savings associated with exempting school bus 
CRSs from this unnecessary attachment requirement. Because the agency 
does not believe exempting school bus CRSs from this requirement would 
affect safety, there are no incremental benefits associated with this 
proposal.
    Comments are requested on the above cost benefit analysis.

VI. Proposed Effective Date

    This NPRM proposes that the amendments would become effective 
immediately on the date of publication of any final rule. The 
amendments would qualify for the exemption from the 30-day effective 
date delay required by 5 U.S.C. 553(d) because they recognize an 
exemption or relieve a restriction.\32\ They would also qualify

[[Page 23015]]

for an exemption from 49 U.S.C. 30111(d) for the same reasons.\33\
---------------------------------------------------------------------------

    \32\ The proposed amendments to S5.5.2(g)(1)(ii) in FMVSS Nos. 
213 and 213b would make changes to certain CRS labeling 
requirements. This provision currently requires that a school bus 
CRS label state, among other things, that the CRS should be secured 
with the vehicle's child restraint anchorage system, if available, 
or with a vehicle belt. However, as explained earlier in this 
document, a school bus CRS is secured to the vehicle using the CRS's 
seat back mount, not with the vehicle's CRS anchorage system or 
belt. The proposal would amend this provision to require that the 
label on a school bus CRS state ``Secure this school bus child 
restraint using the child restraint's seat back mount.'' Therefore, 
although this is a requirement, the amendments would facilitate 
compliance for school bus CRSs because the current requirements do 
not accurately reflect how those CRSs are actually secured to the 
vehicle.
    \33\ Id. (``The Secretary shall specify the effective date of a 
motor vehicle safety standard prescribed under this chapter in the 
order prescribing the standard. A standard may not become effective 
before the 180th day after the standard is prescribed or later than 
one year after it is prescribed. However, the Secretary may 
prescribe a different effective date after finding, for good cause 
shown, that a different effective date is in the public interest and 
publishing the reasons for the finding'')
---------------------------------------------------------------------------

    As explained earlier, this NPRM would delay the compliance date for 
FMVSS No. 213a to December 5, 2026. The compliance date for the 
proposed changes to the labeling requirements in S5.5.2(g)(2)(ii) of 
FMVSS Nos. 213 and 213b would be the same as the effective date in 
order to allow CRS manufacturers to take advantage of the more accurate 
labeling information the amendments would facilitate. Because the 
remainder of the proposed amendments would exempt certain CRSs from 
certain requirements, a compliance date is not necessary for those 
amendments.

VII. Regulatory Notices and Analyses

Executive Order 12866, Executive Order 14192, and DOT Regulatory 
Policies and Procedures

    NHTSA has considered the impact of this rule under Executive Order 
12866 and Executive Order 14192. This NPRM is not considered to be 
significant, and NHTSA has considered the costs and benefits of the 
proposed rule under the principles of these executive orders. Please 
refer to Section V, Costs and Benefits, for this discussion. This NPRM, 
if finalized as proposed, is also expected to be an E.O. 14192 
deregulatory action.

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 entities (i.e., small 
businesses, small organizations and small governmental jurisdictions), 
unless the head of an agency certifies the rule will not have a 
significant economic impact on a substantial number of small entities. 
Agencies must also provide a statement of the factual basis for this 
certification.
    I certify that this rulemaking action would not have a significant 
economic impact on a substantial number of small entities. NHTSA 
estimates there to be 38 manufacturers of child restraints, none of 
which are small businesses. There is no separate NAICS code for child 
restraints. Child restraints systems could fit into the ``Motor Vehicle 
Seating and Interior Trim'' Category (NAICS 336360), ``All Other Motor 
Vehicle Parts Manufacturing'' category (NAICS 336399), or in ``All 
Other Transportation Equipment Manufacturing'' category (NAICS 336999). 
The determination was made based on whether the manufacturer had 500 or 
more employees. All the manufacturers that were identified as small 
manufacturers already met the requirement and, therefore, the analysis 
concluded that there would be no impact on small businesses. Even if 
there were a small CRS manufacturer, as explained in the discussion of 
costs and benefits, the impacts of this rule will not be significant 
and the rule would likely result in cost savings to CRS manufacturers.

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 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.\34\ It is this statutory command by Congress that 
preempts any non-identical State legislative and administrative law 
addressing the same aspect of performance.
---------------------------------------------------------------------------

    \34\ 49 U.S.C. 30103(b)(1).
---------------------------------------------------------------------------

    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.'' \35\ 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.
---------------------------------------------------------------------------

    \35\ 49 U.S.C. 30103(e).
---------------------------------------------------------------------------

    NHTSA rules can also preempt State law 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.\36\
---------------------------------------------------------------------------

    \36\ 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 believes this proposed rule, if finalized, would not have a 
reasonably foreseeable significant effect on the quality of the human 
environment. The public is invited to comment on the impact of the 
proposed agency action.

Paperwork Reduction Act

    Under the procedures established by the Paperwork Reduction Act of 
1995 (PRA) (44 U.S.C. 3501, et. seq.), a

[[Page 23016]]

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 proposed rule would not have any requirements 
that are considered to be information collection requirements as 
defined by the OMB in 5 CFR part 1320.

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 that 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) (Public Law 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 document may be used 
to find this action in the Unified Agenda.

    In accordance with 5 U.S.C. 553(c), DOT solicits comments from the 
public to better inform its rulemaking process. DOT posts these 
comments, without edit, to www.regulations.gov, as described in the

    Your comments must be written and in English. To ensure that your 
comments are correctly filed in the Docket, please include the agency 
name and the docket number or Regulatory Identification Number (RIN) in 
your

[[Page 23017]]

comments. Your comments must not be more than 15 pages long. (49 CFR 
553.21). We established this limit to encourage you to write your 
primary comments in a concise fashion. However, you may attach 
necessary additional documents to your comments. There is no limit on 
the length of the attachments. If you are submitting comments 
electronically as a PDF (Adobe) file, NHTSA asks that the documents be 
submitted using the Optical Character Recognition (OCR) process, thus 
allowing NHTSA to search and copy certain portions of your submissions. 
Please note that pursuant to the Data Quality Act, in order for 
substantive data to be relied upon and used by the agency, it must meet 
the information quality standards set forth in the OMB and DOT Data 
Quality Act guidelines. Accordingly, we encourage you to consult the 
guidelines in preparing your comments. OMB's guidelines may be accessed 
at https://www.transportation.gov/regulations/dot-information-dissemination-quality-guidelines.

How can I be sure that my comments were received?

    If you wish the Docket to notify you upon its receipt of your 
comments, enclose a self-addressed, stamped postcard in the envelope 
containing your comments. Upon receiving your comments, the Docket will 
return the postcard by mail.

How do I submit confidential business information?

    You should submit a redacted ``public version'' of your comment 
(including redacted versions of any additional documents or 
attachments) to the docket using any of the methods identified under 
ADDRESSES. This ``public version'' of your comment should contain only 
the portions for which no claim of confidential treatment is made and 
from which those portions for which confidential treatment is claimed 
has been redacted. See below for further instructions on how to do 
this.
    You also need to submit a request for confidential treatment 
directly to the Office of Chief Counsel. Requests for confidential 
treatment are governed by 49 CFR part 512. Your request must set forth 
the information specified in Part 512. This includes the materials for 
which confidentiality is being requested (as explained in more detail 
below); supporting information, pursuant to Part 512.8; and a 
certificate, pursuant to Part 512.4(b) and Part 512, Appendix A.
    You are required to submit to the Office of Chief Counsel one 
unredacted ``confidential version'' of the information for which you 
are seeking confidential treatment. Pursuant to Part 512.6, the words 
``ENTIRE PAGE CONFIDENTIAL BUSINESS INFORMATION'' or ``CONFIDENTIAL 
BUSINESS INFORMATION CONTAINED WITHIN BRACKETS'' (as applicable) must 
appear at the top of each page containing information claimed to be 
confidential. In the latter situation, where not all information on the 
page is claimed to be confidential, identify each item of information 
for which confidentiality is requested within brackets: ``[ ].'' You 
are also required to submit to the Office of Chief Counsel one redacted 
``public version'' of the information for which you are seeking 
confidential treatment. Pursuant to Part 512.5(a)(2), the redacted 
``public version'' should include redactions of any information for 
which you are seeking confidential treatment (i.e., the only 
information that should be unredacted is information for which you are 
not seeking confidential treatment). NHTSA is currently treating 
electronic submission as an acceptable method for submitting 
confidential business information to the agency under Part 512. Please 
do not send a hardcopy of a request for confidential treatment to 
NHTSA's headquarters. The request should be sent to Dan Rabinovitz in 
the Office of the Chief Counsel at [email protected]. You may 
either submit your request via email or request a secure file transfer 
link. If you are submitting the request via email, please also email a 
courtesy copy of the request to John Piazza at [email protected].

Will the agency consider late comments?

    We will consider all comments received before the close of business 
on the comment closing date indicated above under DATES. To the extent 
possible, we will also consider comments that the docket receives after 
that date. If the docket receives a comment too late for us to consider 
in developing a final rule (assuming that one is issued), we will 
consider that comment as an informal suggestion for future rulemaking 
action.

How can I read the comments submitted by other people?

    You may read the comments received by the docket at the address 
given above under ADDRESSES. The hours of the docket are indicated 
above in the same location. You may also see the comments on the 
internet. To read the comments on the internet, go to http://www.regulations.gov. Follow the online instructions for accessing the 
dockets.
    Please note that even after the comment closing date, we will 
continue to file relevant information in the docket as it becomes 
available. Further, some people may submit late comments. Accordingly, 
we recommend that you periodically check the Docket for new material. 
You can arrange with the docket to be notified when others file 
comments in the docket. See www.regulations.gov for more information.
