NHTSA Denies Petition to Repeal Air Brake Systems Standard

The National Highway Traffic Safety Administration (NHTSA) has denied a petition from William B. Trescott to repeal Federal Motor Vehicle Safety Standard (FMVSS) No. 121, Air Brake Systems, which requires antilock brake systems (ABS) on newly-manufactured vehicles equipped with air-brake systems, citing a lack of evidence supporting the claim that removing ABS would improve safety.
