You will find that some branches of the American Automobile Association will teach a car safety class, as well some high schools. Indeed, car safety classes are required to pass the driving requirement of your driver training. You will, however, find states such as Arizona, California, Massachusetts and Florida that will require safety training if you are convicted of an OUI offense while other states contract with schools such as Skip Barber and Bob Bondurant to help new drivers round out their skills. By rounding out their skills, people who take these classes will gain invaluable knowledge in defensive driving and safety techniques.
