The legislation, enacted in 1966, represents a landmark moment in the pursuit of safer roadways and vehicles within the United States. It established federal authority to set and enforce safety standards for motor vehicles and related equipment. Prior to its passage, vehicle safety regulations were largely nonexistent or varied considerably from state to state.
This act significantly improved vehicle safety by mandating safety standards for automobiles, tires, and other vehicle components. It led to the development and implementation of crucial safety features, such as seat belts, padded dashboards, and shatter-resistant windshields. Furthermore, it created the National Highway Traffic Safety Administration (NHTSA) to oversee and enforce these regulations, as well as to conduct research into traffic safety issues. Its historical context lies in a growing concern over the rising number of traffic fatalities and injuries, prompting a national response to address the problem.
