The Federal Motor Vehicle Safety Standards (FMVSS) are
U.S. federal
vehicle regulations specifying design, construction, performance, and durability requirements for
motor vehicles and regulated
automobile safety-related components, systems, and design features. They are the U.S. counterpart to the UN Regulations developed by the
World Forum for Harmonization of Vehicle Regulations and recognized to varying degree by most countries except the United States.
Canada has a system of analogous rules called the Canada Motor Vehicle Safety Standards (CMVSS), which overlap substantially but not completely in content and structure with the FMVSS. The FMVSS/CMVSS requirements differ significantly from the international UN requirements, so
private import of foreign vehicles not originally manufactured to North American specifications is difficult or impossible.
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
seat belts in roadgoing vehicles.
