The National Highway Traffic Safety Administration (NHTSA) establishes standards to ensure the safety of vehicles on American roads. These standards cover various aspects, including vehicle performance, crashworthiness, and fuel efficiency. They aim to reduce accidents and protect drivers, passengers, and pedestrians. NHTSA standards also regulate vehicle recalls and compliance testing. Manufacturers must adhere to these guidelines to ensure their vehicles meet safety requirements before they can be sold. By enforcing these standards, the NHTSA helps promote safer driving conditions and encourages innovation in vehicle safety technology.
