{"abstract":"NHTSA is announcing a 15-day extension of the comment period 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 Draft Supplemental Environmental Impact Statement (Draft SEIS) that accompanies the proposed rule. The comment period was to end on January 20, 2026 (45 days after publication of the proposed rule in the Federal Register). This document extends the comment period to February 4 to allow the public additional time to comment on the proposed rule. NHTSA is denying requests for additional public hearings based on the number 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.","action":"Proposed rule; extension of comment period.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"National Highway Traffic Safety Administration","name":"National Highway Traffic Safety Administration","id":345,"url":"https://www.federalregister.gov/agencies/national-highway-traffic-safety-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/345","parent_id":492,"slug":"national-highway-traffic-safety-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/01/14/2026-00537.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"523","title":49},{"chapter":null,"citation_url":null,"part":"531","title":49},{"chapter":null,"citation_url":null,"part":"533","title":49},{"chapter":null,"citation_url":null,"part":"536","title":49},{"chapter":null,"citation_url":null,"part":"537","title":49}],"citation":"91 FR 1494","comment_url":null,"comments_close_on":"2025-12-05","correction_of":null,"corrections":[],"dates":"The comment period for the proposed rule (90 FR 56438) published December 5, 2025, is extended.
