{"abstract":"This interim final rule amends the seat belt warning requirements in Federal Motor Vehicle Safety Standard (FMVSS) No. 208, \"Occupant crash protection\" in response to petitions for reconsideration of the January 2025 final rule. This interim final rule delays the compliance dates and makes technical clarifications to the regulatory text. NHTSA denies the remainder of the requests. Though these amendments are effective immediately, to benefit from comments interested parties and the public may have, NHTSA requests that any comments be submitted to the docket for this rule. Following the close of the comment period, NHTSA will publish a final rule responding to any comments received and making any appropriate changes to the interim final rule.","action":"Interim final rule; request for comments.","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/2026/04/06/2026-06614.html","cfr_references":[{"chapter":null,"citation_url":null,"part":571,"title":49}],"citation":"91 FR 17144","comment_url":null,"comments_close_on":"2026-05-21","correction_of":null,"corrections":[],"dates":"This interim final rule is effective April 6, 2026.
