{"abstract":"This final rule amends NHTSA's regulation governing Event Data Recorders (EDR or EDRs) to delay the implementation schedule for expanded pre-crash data capture requirements. In response to petitions for reconsideration of a final rule published on December 18, 2024, the agency is adopting a four-year phase-in compliance schedule that begins September 1, 2028. This action ensures the increased pre-crash data capture requirements are integrated into the vehicle fleet in a manner that aligns with manufacturer production cycles and technical feasibility.","action":"Final rule.","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/2026/05/18/2026-09849.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"563","title":49},{"chapter":null,"citation_url":null,"part":"585","title":49}],"citation":"91 FR 28432","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":["https://www.federalregister.gov/api/v1/documents/C1-2026-09849"],"dates":"Effective Date: This rule is effective June 17, 2026.","disposition_notes":null,"docket_ids":["Docket No. NHTSA-2025-0050"],"dockets":[{"supporting_documents":[],"agency_name":"NHTSA","documents":[{"comment_count":0,"comment_start_date":"2026-05-18","updated_at":"2026-05-18T10:58:16.922-04:00","comment_url":"https://www.regulations.gov/commenton/NHTSA-2025-0050-0009","allow_late_comments":false,"id":"NHTSA-2025-0050-0009","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":0,"id":"NHTSA-2025-0050","title":"Response to Petitions for Reconsideration, Part 563 Event Data Recorders"}],"document_number":"2026-09849","effective_on":"2026-06-17","end_page":28443,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/05/18/2026-09849.xml","html_url":"https://www.federalregister.gov/documents/2026/05/18/2026-09849/event-data-recorders","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-09849?publication_date=2026-05-18","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-05-18/2026-09849/mods.xml","not_received_for_publication":null,"page_length":12,"page_views":{"count":1658,"last_updated":"2026-11-07 20:15:03 -0500"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-05-18/pdf/2026-09849.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-09849.pdf?1778849114","publication_date":"2026-05-18","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/05/18/2026-09849.txt","regulation_id_number_info":{"2127-AM78":{"issue":"202504","html_url":"https://www.federalregister.gov/regulations/2127-AM78/response-to-petitions-for-reconsideration-event-data-recorders","title":"Response to Petitions for Reconsideration, Event Data Recorders","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202504&RIN=2127-AM78&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2127-AM78"],"regulations_dot_gov_info":{"supporting_documents":[],"comments_count":0,"agency_id":"NHTSA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=NHTSA-2025-0050","supporting_documents_count":0,"docket_id":"NHTSA-2025-0050","document_id":"NHTSA-2025-0050-0009","regulation_id_number":null,"title":"Response to Petitions for Reconsideration, Part 563 Event Data Recorders","checked_regulationsdotgov_at":"2026-05-19T11:55:04Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":28432,"subtype":null,"title":"Event Data Recorders","toc_doc":"Event Data Recorders","toc_subject":null,"topics":["Motor vehicle safety","Motor vehicles","Reporting and recordkeeping requirements"],"type":"Rule","volume":91}
