The National Highway Traffic Safety Administration (NHTSA) is like a big group of grown-ups who work to keep you safe when you're in a car. They make rules to make sure cars are built and driven in a safe way. They also do research to find out how to make cars even safer in the future.
The NTHSA helps prevent accidents by making sure car manufacturers follow certain safety regulations such as making sure cars have seat belts, airbags, and anti-lock brakes. They also work to reduce the number of people who are hurt or killed in car accidents by setting safety standards for cars, trucks, and buses. This means that every time you get in a car, you can feel confident that it has gone through safety testing to make sure it won't hurt you.
If there's a problem with your car or something goes wrong while you're driving, the NHTSA can help you. They keep track of safety defects and will make sure the manufacturer fixes the problem if the car is still under warranty.
So, to sum it up, the National Highway Traffic Safety Administration works to make sure cars are safe for you to ride in and helps reduce the number of accidents and injury caused by car crashes.
