Commercial road transport safety
FMCSA regulates safety in covered commercial motor vehicle operations. Operating equipment requirements are distinct from NHTSA’s manufacturer-focused vehicle and equipment certification framework.
Federal Motor Carrier Safety Administration is represented in this collection through the specific publications listed below. Begin with the product, activity and responsible party identified by the source. A reference to an agency does not establish that every product in an industry follows the same pathway. Scope, definitions, exceptions and the status of an adopted technical document can change the conclusion.
Use the original publication to establish the requirement, then connect it to the actual model, configuration, process or transaction. Keep source dates separate from effective and compliance dates. Where several agencies are relevant, preserve a distinct conclusion for each framework. A test report, registration, approval, certification and voluntary program claim should be assessed for the precise object and conditions they cover.

49 CFR Part 393
Part 393 addresses equipment needed for safe operation of covered commercial motor vehicles. It includes lighting, brakes, glazing, fuel systems, coupling devices, tires and cargo securement subjects. The rules connect the condition and use of the operating vehicle with equipment requirements; they should be read alongside the manufacturer-focused Federal Motor Vehicle Safety Standards where applicable.
