The American organization that determines and enforces performance standards in motor vehicles. It is a federal agency that provides funds to state govern­ments and can influence states by granting funding only if certain stan­dards are met. The NHTSA establishes safety requirements for vehicles, examples of which include a national speed limit and a national per se alcohol limit of 80 mg of alcohol/100 mL of blood. These requirements are often adopted in law elsewhere, including in Canada. The NHTSA also performs investigations and research into vehicle safety and crashes and then issues recommendations or standards as a result.
