Automotive regulations are rules and standards set by governments to ensure the safety, environmental impact, and performance of vehicles. These regulations cover various aspects, including vehicle design, emissions, fuel efficiency, and safety features. Organizations like the National Highway Traffic Safety Administration (NHTSA) in the United States and the European Commission in Europe play key roles in establishing and enforcing these standards. Compliance with automotive regulations is essential for manufacturers to sell their vehicles in different markets. These rules help protect consumers by ensuring that cars meet specific safety criteria, such as crash test performance and the presence of safety equipment like airbags and seatbelts.
