The Federal Motor Vehicle Safety Standards (FMVSS) are
U.S. federal
vehicle regulations specifying design, construction, performance, and durability requirements for
motor vehicle
A motor vehicle, also known as motorized vehicle or automotive vehicle, is a self-propelled land vehicle, commonly wheeled, that does not operate on rails (such as trains or trams) and is used for the transportation of people or cargo.

FMVSS are divided into three categories: crash avoidance (100-series),
crashworthiness (200-series), and post-crash survivability (300-series). The first regulation, FMVSS No. 209, was adopted on 1 March 1967 and remains in force to date though its requirements have been periodically updated and made more stringent. It stipulates the requirements for
