Parts and Accessories Necessary for Safe Operation; General Amendments

Final rule.
FMCSA amends part 393 of the Federal Motor Carrier Safety Regulations (FMCSRs), Parts and Accessories Necessary for Safe Operation. The amendments are intended to remove obsolete and redundant regulations; respond to several petitions for rulemaking; provide improved definitions of vehicle types, systems, and components; resolve inconsistencies between part 393 and the National Highway Traffic Safety Administration's Federal Motor Vehicle Safety Standards (49 CFR part 571); and codify certain FMCSA regulatory guidance concerning the requirements of part 393. Generally, the amendments do not involve the establishment of new or more stringent requirements, but a clarification of existing requirements. This action is intended to make many sections more concise, easier to understand and more performance oriented.
