{"abstract":"This document initiates rulemaking to amend Federal Motor Vehicle Safety Standard (FMVSS) No. 111, Rearview Mirrors,\\1\\ to improve a driver's ability to see areas to the rear of a motor vehicle in order to mitigate fatalities and injuries associated with backover incidents. The agency and Congress are concerned that vehicles have \"blind zones,\" \\2\\ areas behind the vehicle in which drivers may have difficulty seeing and avoiding a person or other obstacle. Through this notice, NHTSA presents its initial research efforts and solicits additional information that will enable the agency to develop an effective proposal to mitigate backover incidents related to vehicle rear blind zones. ---------------------------------------------------------------------------","action":"Advance notice of proposed rulemaking (ANPRM).","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/2009/03/04/E9-4500.html","cfr_references":[{"chapter":null,"citation_url":null,"part":571,"title":49}],"citation":"74 FR 9478","comment_url":null,"comments_close_on":"2009-05-04","correction_of":null,"corrections":[],"dates":"Comments must be received on or before May 4, 2009.","disposition_notes":null,"docket_ids":["Docket No. NHTSA-2009-0041"],"dockets":[],"document_number":"E9-4500","effective_on":null,"end_page":9520,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2009/03/04/E9-4500.xml","html_url":"https://www.federalregister.gov/documents/2009/03/04/E9-4500/federal-motor-vehicle-safety-standard-rearview-mirrors","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E9-4500?publication_date=2009-03-04","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2009-03-04/E9-4500/mods.xml","not_received_for_publication":null,"page_length":43,"page_views":{"count":11181,"last_updated":"2026-05-11 10:15:15 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2009-03-04/pdf/E9-4500.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2009-03-04","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2009/03/04/E9-4500.txt","regulation_id_number_info":{"2127-AK43":{"issue":"201110","html_url":"https://www.federalregister.gov/regulations/2127-AK43/federal-motor-vehicle-safety-standard-no-111-rearview-mirrors","title":"Federal Motor Vehicle Safety Standard No. 111, Rearview Mirrors","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201110&RIN=2127-AK43&operation=OPERATION_EXPORT_XML","priority_category":"Economically Significant"}},"regulation_id_numbers":["2127-AK43"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-11-15T15:37:48Z"},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":9478,"subtype":null,"title":"Federal Motor Vehicle Safety Standard; Rearview Mirrors","toc_doc":"Rearview Mirrors","toc_subject":"Federal Motor Vehicle Safety Standards:","topics":[],"type":"Proposed Rule","volume":74}
