SUPPLEMENTARY INFORMATION:

I. Executive Summary

    On November 25, 2024, the National Highway Traffic Safety 
Administration (NHTSA) published in the Federal Register a final 
decision notice that established a new crashworthiness pedestrian 
program as part of the Agency's New Car Assessment Program (NCAP).\1\ 
Subsequently, on December 3, 2024, NHTSA published a final decision 
notice that added four new advanced driver assistance systems (ADAS) 
technologies to NCAP--blind spot warning (BSW), blind spot intervention 
(BSI), lane keeping assist (LKA), and pedestrian automatic emergency 
braking (PAEB)--and updated existing requirements for automatic 
emergency braking (AEB).\2\ These program updates were to be 
implemented beginning with model year 2026 vehicles. This notice 
announces that implementation of the changes discussed in the November 
2024 and December 2024 notices are postponed for one model year to 
model year 2027 vehicles. The Agency will continue to recommend the 
existing ADAS technologies--forward collision warning (FCW), crash 
imminent braking (CIB), dynamic braking support (DBS), and lane 
departure warning (LDW)--for the 2026 model year. For the reasons 
explained elsewhere in this notice, NHTSA will, however, also assign 
credit to any vehicle models for which the respective vehicle 
manufacturer has provided an attestation of passing performance for one 
or more of the new ADAS technologies in their response to NCAP's annual 
vehicle information request for model year 2026 vehicles. Credit for 
vehicles exhibiting passing performance for the adopted crashworthiness 
pedestrian protection requirements will not be issued for the 2026 
model year.

II. Background

    NHTSA established the NCAP program in 1978 in response to Title II 
of the Motor Vehicle Information and Cost Savings Act of 1972. The 
program began with frontal impact testing in 1979 and has expanded over 
the years to include side impact barrier testing in 1996, rollover 
assessments in 2000 and 2003, side impact pole testing in 2011,

[[Page 45464]]

and assessments for advanced driver assistance systems (ADAS) beginning 
with model year 2011 vehicles. Adopted ADAS technologies have included 
electronic stability control (ESC), forward collision warning (FCW), 
and lane departure warning (LDW), added in 2011; rear visibility 
systems, adopted in 2013; and more recently, crash imminent braking 
(CIB) and dynamic braking support (DBS), known collectively as 
automatic emergency braking (AEB), added in 2015 for model year 2018 
vehicles. While NHTSA assigns star ratings on its website for the 
original program elements (i.e., frontal impact, side impact, and 
rollover assessments), it uses checkmarks to recommend to consumers 
those ADAS technologies that meet NCAP's performance requirements.
    On December 3, 2024, NHTSA published a final decision notice \3\ 
announcing its plan to update NCAP's ADAS program to include several 
new technologies--blind spot warning (BSW), blind spot intervention 
(BSI), lane keeping assist (LKA), and pedestrian automatic emergency 
braking (PAEB)--as well as to increase the stringency for the existing 
performance requirements related to AEB. Around the same time, in a 
final decision notice published on November 24, 2024,\4\ the Agency 
also announced the addition of a crashworthiness pedestrian protection 
program to NCAP. NHTSA stated that changes adopted for both notices 
would be implemented beginning with model year 2026 vehicles.

III. Rationale for Postponing NCAP Enhancements for One Model Year

    NHTSA has decided to postpone implementation of adding 
crashworthiness pedestrian protection information and adding 
recommendations for the four new ADAS technologies to NCAP for one 
model year. These program changes will now be effective beginning with 
model year 2027 vehicles. The Agency believes delaying the planned 
updates is appropriate to address concerns expressed by the automotive 
industry and to provide the Agency with sufficient time to implement 
the planned changes in a manner that ensures the integrity of the NCAP 
program is upheld.

A. Concerns Expressed by Auto Innovators

    On April 25, 2025, NHTSA received a letter from the Alliance for 
Automotive Innovation (Auto Innovators) submitted in response to the 
Agency's November 25, 2024 and December 3, 2024 final decision notices 
on adding to NCAP a pedestrian protection program and four new ADAS 
technologies, respectively. In its letter, Auto Innovators, a 
consortium of vehicle manufacturers and suppliers, requested that NHTSA 
delay the planned program changes for NCAP by at least one year, citing 
(1) NHTSA's failure to publish test procedures for evaluating 
crashworthiness pedestrian protection, (2) outstanding technical 
questions surrounding the Agency's final decisions for both the new 
ADAS technologies and the crashworthiness pedestrian protection 
program, (3) an implementation timeline that limits manufacturer 
participation by imposing unnecessary barriers, and (4) a lack of 
comparative ratings to allow consumers to differentiate between the 
safety performance of vehicles.
    Regarding a lack of published test procedures for crashworthiness 
pedestrian protection assessments, Auto Innovators added, while it 
appreciates NHTSA's attempt to align with the corresponding European 
New Car Assessment Program (Euro NCAP) test protocols, that a delay in 
finalizing and publishing official test procedures for the U.S. NCAP's 
crashworthiness pedestrian protection assessments ``is creating 
unnecessary uncertainty [and undue burden] for manufacturers, is 
preventing manufacturers from fully evaluating their current and future 
fleet, and is limiting their ability to identify any specific changes 
that may be needed in order to meet the new pedestrian protection 
crashworthiness ratings.''
    With respect to outstanding technical questions surrounding NHTSA's 
final decisions for both program updates, Auto Innovators expressed 
that validation testing in process may introduce questions or issues 
that would have to be addressed quickly to ensure manufacturers 
continue to participate in the NCAP program. Adding to this, the group 
asserted that there is a significant cost associated with vehicle 
testing, and manufacturers will be cautious to complete testing 
proactively due to concern of having to repeat testing to account for 
differences in test procedures.
    As mentioned, the organization also conveyed concerns regarding 
time and resource constraints given NHTSA's decision to invoke program 
changes with less than a year's notice. Auto Innovators contended that 
the adopted implementation schedule did not allow sufficient time for 
manufacturers to implement vehicle design changes to meet the new NCAP 
performance requirements, and as such, proceeding on the current 
timetable would be a disservice to not just vehicle manufacturers, but 
also consumers and NHTSA, because manufacturers would be able to attest 
to passing performance only for a limited number of vehicle models. The 
group explained that there are ``practical constraints and logistical 
challenges that limit how quickly manufacturers can respond,'' because 
manufacturers must not only redesign vehicle models to meet the new 
requirements, but must also procure new test equipment, make upgrades 
to test facilities, and adjust test schedules to accommodate the new 
testing.
    Auto Innovators also commented on NHTSA's decision to establish a 
binary pass/fail performance criterion (with passing performance 
conveyed in the form of a checkmark on NHTSA's website) in lieu of a 
comparative rating system for the two program changes. The organization 
stated that this type of information is of limited use to consumers, as 
they will be unable to differentiate between vehicles offering 
different levels of performance. Furthermore, the group claimed that 
such a system, in general, is not conducive to incentivizing 
manufacturers to make incremental safety improvements, a main goal of 
NCAP. While Auto Innovators recognized that NHTSA is planning to 
conduct additional research to assess consumers' ratings preferences, 
the group also asserted that this research should have been completed 
before the Agency published its November 2024 and December 2024 final 
decision notices.
    Auto Innovators stated that NHTSA must address all the 
aforementioned issues to ensure the NCAP program maintains credibility 
and consumers are provided with meaningful information.
    Auto Innovators subsequently reaffirmed many of the concerns 
outlined in their April 25, 2025 letter in response to the Department 
of Transportation's (DOT's) request for information (RFI) on ``Ensuring 
Lawful Regulation; Reducing Regulation and Controlling Regulatory 
Costs.'' \5\ In its comment submission, the organization requested that 
NHTSA delay implementation of the final decision on the ADAS and 
crashworthiness pedestrian protection program updates for NCAP by at 
least one year. While Auto Innovators expressed support for the program 
updates, it asserted that the new test procedures for both program 
components would ``add significant time and resource burdens for both

[[Page 45465]]

manufacturers and NHTSA,'' and contended that a delay of the program 
updates would ``improve the efficiency of the program and address any 
outstanding technical concerns.''
---------------------------------------------------------------------------

    \5\ 90 FR 14593.
---------------------------------------------------------------------------

Agency Response
    NHTSA acknowledges the concerns Auto Innovators has expressed. The 
Agency appreciates that the delay in finalizing and publishing test 
procedures has created uncertainty for manufacturers. It is 
understandable that manufacturers may not want to invest in redesigning 
vehicle models or conducting testing to evaluate their vehicles' 
ability to provide adequate protection to pedestrians in a crash if the 
actual test procedure and requirements are unknown. Vehicle testing 
imposes significant costs, and, as such, it may be cost prohibitive for 
many vehicle manufacturers to conduct testing if the results of that 
testing may later be deemed invalid due to changes to test procedures 
or requirements stemming from the Agency's validation testing. NHTSA 
also recognizes the cost and time commitment inherent to sourcing new 
laboratory equipment and making facility updates to accommodate new 
testing in a relatively short timeframe. These are all valid reasons to 
request that the Agency delay the implementation of the new NCAP 
requirements.
    Auto Innovators' contention that all parties--manufacturers, 
consumers, and NHTSA--are best served if manufacturers are provided 
with sufficient time to implement vehicle design changes, perform 
confirmatory testing, and submit performance attestations to NHTSA 
early on in a model year is also reasonable. However, NHTSA does not 
mean to assert that an extended amount of time is needed to ensure all 
vehicles can achieve credit for passing performance at the onset of any 
new NCAP program update. NCAP is a consumer information program, not a 
compliance program. NCAP provides consumers with safety information on 
vehicle performance that exceeds that which is expected for minimum 
compliance standards, and as such, it also serves to incentivize 
vehicle manufacturers to make safety improvements to their vehicles 
that go beyond safety expectations so they may promulgate them and 
increase consumer interests. Given this, the Agency believes it is 
unnecessary to assure the vast majority of vehicles achieve passing 
performance for NCAP's assessments at the onset of any program updates.
    Regarding Auto Innovators' opinion that NHTSA must establish a 
comparative rating system to ensure consumers are provided with 
meaningful information, the Agency agrees with Auto Innovators that 
there is a benefit to providing consumers with comparative crash 
avoidance and crashworthiness pedestrian protection ratings. This is 
not to say, however, that there is no benefit to the pass/fail 
performance metrics the Agency has adopted. NHTSA plans to assign 
credit (via checkmark) for each of the new ADAS technologies--AEB, 
PAEB-day, PAEB-night, BSW, BSI, and LKA--separately. Therefore, 
consumers may still differentiate among performance for multiple 
vehicles by comparing the number of ADAS systems that pass NCAP's 
performance requirements for each vehicle. As such, NHTSA believes 
vehicle manufacturers will still be enticed to make vehicle safety 
improvements in a timely manner.
    The Agency notes that it has used checkmarks to signify passing 
system performance for all ADAS technologies included in NCAP to date, 
and they have proven to be a useful tool to encourage vehicle 
manufacturers to make system improvements to advance vehicles' crash 
avoidance capabilities. When NHTSA first added FCW to NCAP in 2011, 
approximately six percent of vehicles were equipped with systems that 
were able to meet NCAP's performance criteria whereas 92 percent were 
able to do so in 2023. Similarly, less than 5 percent of vehicles were 
equipped with CIB systems that met NCAP's performance requirements when 
the technology was first adopted in 2017, and yet over 80 percent of 
model year 2023 vehicles met these requirements. The Agency sees no 
reason to assume a different outcome would result by conveying system 
performance in a similar manner for the new ADAS technologies or 
crashworthiness pedestrian protection component adopted for the 
program. Furthermore, NHTSA does not reason that it would be more 
beneficial to consumers to impose significant, additional delays in 
implementing NCAP's most recent program updates as the Agency waits for 
the completion of its pending consumer information research centering 
around updates to the safety ratings portion of the vehicle Monroney 
Label. The Agency recognizes, as Auto Innovators also stated, that any 
additional program delays would not be ideal given the long-standing 
delays in updating NCAP since its last major upgrade implemented for 
model year 2011 vehicles.\6\ This being said, NHTSA does see merit in a 
one year delay for implementation of the adopted ADAS and 
crashworthiness pedestrian protection additions to address some of the 
concerns expressed by Auto Innovators and recognized by NHTSA. Delaying 
implementation of the changes to NCAP for one year should give 
manufacturers adequate time to prepare for the enhancements to the 
program, particularly as the Agency is publishing the crashworthiness 
pedestrian protection test procedures as a follow-on to this notice.\7\

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

B. Ensuring Program Integrity

    The delay requested by Auto Innovators will also provide NHTSA with 
sufficient time to complete actions necessary to ensure the continued 
integrity of the NCAP program. The Agency will be able to make the 
necessary updates to the www.NHTSA.gov website to reflect the program 
changes and develop clear, consumer-friendly language that accurately 
communicates those changes. Along these lines, NHTSA will also be able 
to progress with development of two databases necessary to collect 
crash avoidance and crashworthiness pedestrian protection test data 
from NCAP's test labs and annual vehicle information data from vehicle 
manufacturers. These efforts are expected to increase program 
efficiency and data accuracy and reduce the reporting burden on vehicle 
manufacturers.
    A one-year delay of the program enhancements will also allow the 
Agency time to complete ADAS and crashworthiness pedestrian protection 
validation testing of model year 2025 vehicles. Completion of this 
testing prior to the official implementation of the program updates is 
ideal so that NHTSA has time to revise the new ADAS test procedures to 
(1) resolve any errors or conflicts noted during the validation 
testing, (2) provide clarification to address any ambiguities observed 
for test conduct or performance requirements, and (3) provide any 
refinements that may be deemed beneficial to improve test 
reproducibility. The Agency took similar steps prior to the last major 
update to NCAP by providing clarifying language and corrections to the 
side impact moving deformable barrier and side pole test procedures, in 
addition to the respective dummy seating procedures and qualification 
procedures after the test procedures were published and the validation 
tests were completed.

[[Page 45466]]

IV. Data Collection and Reporting Requirements

    Because NHTSA is delaying the adopted program updates for one year, 
manufacturers need not provide performance attestations for the new 
ADAS or crashworthiness pedestrian protection NCAP requirements for 
model year 2026 vehicles. Rather, such declarations would be submitted 
for vehicles beginning with the 2027 model year to obtain credit for 
the new program elements. Manufacturers may continue to provide NCAP 
with performance attestations for the four existing ADAS technologies--
FCW, CIB, DBS, and LDW--for their model year 2026 vehicles. Since the 
Agency did not ask for performance declarations for the existing 
technologies as part of NCAP's most recent annual information request 
for model year 2026 vehicles, NHTSA plans to issue a supplemental 
request for information from vehicle manufacturers to obtain this data.

V. Credit for Existing and New Technologies but Not Crashworthiness 
Pedestrian Protection

    NHTSA recognizes, as Auto Innovators stated, that manufacturers may 
have expended time and resources to perform testing in accordance with 
NCAP's new ADAS test protocols with the expectation of obtaining 
performance credit for any model year 2026 vehicles that provide 
passing performance for any of the newly adopted ADAS technologies. As 
such, the Agency will still issue checkmarks for the new ADAS 
technologies for these vehicle models. NHTSA plans to assign checkmarks 
for those vehicles achieving passing performance for the ADAS 
technologies that currently exist in NCAP (i.e., LDW, FCW, CIB, and 
DBS) as well as for those that have been newly adopted (i.e., AEB, 
PAEB-day, PAEB-night, BSW, BSI, and LKA).
    NHTSA acknowledges that some individuals or entities may be 
concerned regarding how potential future updates to NCAP's new ADAS 
test procedures will affect performance credit awarded for model year 
2026 vehicles. While the Agency recognizes that the test procedures for 
the newly adopted ADAS technologies may be updated to address 
ambiguities or to provide clarification, it does not believe that 
future updates will affect performance requirements. Accordingly, NHTSA 
does not anticipate removing credit for model year 2026 vehicles that 
achieve passing performance using the test protocols published with 
NCAP's December 2024 ADAS final decision notice. NHTSA would permit 
ADAS performance attestations to carry over from the 2026 model year to 
the 2027 model year for those vehicles having systems that have no 
changes to hardware or software such that their performance during 
NCAP's updated ADAS tests is unchanged from one model year to the next.
    The Agency notes that it will not be similarly providing early 
credit for those model year 2026 vehicles that are able to achieve 
passing performance for NCAP's crashworthiness pedestrian protection 
program. The Agency is making a distinction for this program component 
compared to the new ADAS technologies because it does not believe 
manufacturers have been provided with sufficient information to conduct 
testing that would be assured to meet the test protocol that will 
ultimately be published for NCAP's crashworthiness pedestrian 
protection assessments. As such, credit for passing performance in 
NCAP's crashworthiness pedestrian protection tests will not be assigned 
on the Agency's website until the 2027 model year.

VI. Conveying Information to Consumers

    Given the decisions discussed above, NHTSA plans to update its 
website to assign credit (via a checkmark) to any model year 2026 
vehicles achieving passing system performance for the existing ADAS 
technologies (i.e., FCW, CIB, DBS, and LDW) as well as the newly 
adopted technologies (i.e., AEB, PAEB-day, PAEB-night, BSW, BSI, and 
LKA). In addition, the Agency plans to assign credit for the existing 
ADAS technologies (i.e., FCW, CIB, DBS, and LDW), for any vehicles 
receiving credit for the corresponding new technologies, AEB and LKA, 
as applicable.
    As an example, if a vehicle manufacturer has indicated in its 
submission to NCAP's annual information request that a particular 
vehicle model achieves passing performance in NCAP's new AEB test, this 
vehicle model will be assigned credit for AEB and will separately be 
assigned credit for FCW, CIB, and DBS. Similarly, if the manufacturer 
indicates to NCAP that the vehicle model passes NCAP's new LKA test, it 
will be assigned credit for LKA as well as LDW.
    Assigning credit for the existing comparable ADAS tests when 
passing performance is achieved for the related new, more stringent 
tests, should limit consumer confusion. When comparing a vehicle that 
passes NCAP's AEB and LKA tests to a vehicle that does not pass these 
tests, the consumer will always see performance credit assigned to a 
greater number of technologies for the former (i.e., 6 technologies, or 
more) compared to the latter (i.e., at most 4 technologies). In this 
way, consumers should be encouraged to seek out those vehicle models 
that afford better overall system performance to prevent frontal 
crashes and lane/roadway departures.
    The Agency believes pursuing an approach whereby credit is imputed 
to NCAP's existing ADAS tests when the comparable new ADAS tests are 
passed should also lessen manufacturer test burden and reduce overall 
testing costs, as manufacturers who have conducted the NCAP's new ADAS 
tests will not have to separately perform the program's existing ADAS 
tests for the same vehicle model. Furthermore, NHTSA reasons such an 
approach is appropriate considering that the more stringent test 
protocols adopted for AEB and LKA encompass the performance 
requirements previously established for FCW, CIB, DBS, and LDW, 
respectively.
    NHTSA's planned approach of awarding credit to both the existing 
and future ADAS technologies will be limited to the 2026 model year. 
For 2027 model year vehicles, the Agency will assign credit only to 
those vehicles achieving passing performance for the newly adopted ADAS 
technologies--AEB, PAEB-day, PAEB-night, BSW, BSI, and LKA.
    As the Agency has stated that it does not intend to provide early 
credit for those model year 2026 vehicles that are able to achieve 
passing performance for NCAP's crashworthiness pedestrian protection 
program, NHTSA will not begin to assign crashworthiness pedestrian 
protection credit until the 2027 model year. No credit for 
crashworthiness pedestrian protection will be assigned for model year 
2026 vehicles.
