for the proposed rule entitled The Safer Affordable Fuel-Efficient 
(SAFE) Vehicles Rule III for Model Years 2022 to 2031 Passenger Cars 
and Light Trucks, published in the December 5, 2025 issue of the 
Federal Register. NHTSA is also extending the comment period for the

Register). This document extends the comment period to February 4 to 
allow the public additional time to comment on the proposed rule. NHTSA

of testifiers that signed up to testify for NHTSA's virtual public 
hearing, which was announced via Federal Register notice on December 
12, 2025 and held on January 7, 2026.

SUPPLEMENTARY INFORMATION: On December 5, 2025, NHTSA published in the 
Federal Register a proposed rule titled ``The Safer Affordable Fuel-
Efficient (SAFE) Vehicles Rule III for Model Years 2022 to 2031 
Passenger Cars and Light Trucks.'' \1\ The public comment period for 
the proposed rule was scheduled to end on January 20, 2026. 
Additionally, the public comment period for NHTSA's Draft SEIS for the 
proposed rule likewise was scheduled to end on January 20, 2026. NHTSA 
also published a notice in the Federal Register on December 12, 2025 
announcing a virtual public hearing to be held on January 7, 2026, 
potentially extending into January 8, 2026 if needed.\2\ NHTSA received 
four requests to extend the comment period (received by the agency's 
dockets) as of the date of this notice. These requesters also asked 
that the agency hold additional public hearings to allow more 
opportunities for oral presentation of public comments, in additional 
locations. A summary of these requests is as follows:

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

    In support of their requests for longer comment periods and 
additional public hearings, all requesters cited the time needed for 
careful analysis and review, the technically complex changes from prior 
analyses, and the potential significance of the proposed rule's 
potential effects on the U.S. economy, consumers, human health, and the 
environment.
    After thorough consideration of these requests, NHTSA is extending 
the public comment period for the proposed rule, as well as for the 
Draft SEIS, by 15 days to February 4, 2026--a total of 60 days. The 
agency believes that this amount of time should be adequate for 
commenters to review fully and comment meaningfully on the proposed 
rule and on the Draft SEIS. This length of time comports with prior 
NHTSA CAFE comment periods \3\ and comment periods for other 
significant rules,\4\ while balancing the public interest in timely 
completion of the final rule.
---------------------------------------------------------------------------

    \3\ 86 FR 49602 (Sept. 3, 2021); 88 FR 56128 (Aug. 17, 2023).
    \4\ See, e.g., Regulations.gov, Learn About the Regulatory 
Process, https://www.regulations.gov/learn (``In a typical case, an 
agency will allow 60 days for public comment. However, in some 
cases, they provide either shorter or longer comment periods.'').
---------------------------------------------------------------------------

    NHTSA is denying requests for additional public hearings and for 
hearings in additional locations. NHTSA reserved two days for the 
agency's virtual public hearing to accommodate all potential requests 
to testify, but the agency received requests to testify that only 
covered part of one day. Given the number of requestors to testify, and 
that a virtual public hearing format allows the most flexibility for 
diverse public comments from commenters in multiple locations across 
the country, NHTSA did not need to extend the virtual public hearing 
into the additional day, nor did the agency schedule additional in-
person public hearings. In addition, given the ongoing opportunity for 
written comment, the requesters have not demonstrated a need for 
additional public hearings.
