Federal Motor Vehicle Safety Standards; Rear Impact Guards; Notice of Proposed Rulemaking

Summary

The National Highway Traffic Safety Administration (NHTSA) is proposing changes to the Federal motor vehicle safety standard for trailers and semitrailers, specifically excluding trailers with 'tuckunder liftgates' from the energy absorption requirements and amending the definition of 'special purpose vehicle' to better describe the cubic area at the rear of the trailer.
