{"abstract":"On May 27, 1998, NHTSA published a final rule amending selected Federal Motor Vehicle Safety Standards (FMVSSs) by converting English measurements specified in those standards to metric measurements. In this document, NHTSA corrects typographical and other errors in the May 1998 final rule. This document also responds to a petition for reconsideration filed by Toyota, and public comments by the Truck Manufacturers Association and Ford to correct typographical errors in the final rule. The corrections of errors in this final rule are not intended to make any changes in the stringency of the affected FMVSSs.","action":"Final rule, technical amendments; response to petition for reconsideration.","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/1998/09/24/98-25609.html","cfr_references":[{"chapter":null,"citation_url":null,"part":571,"title":49}],"citation":"63 FR 50995","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective May 27, 1999.
