What is a school bus?
Under federal law, any motor vehicle designed to carry more than 10 persons is classified as a bus. A bus is classified as a school bus if it is used, or intended for use, in transporting students to and from school or school-related activities. At the direction of the U.S. Congress, the U.S. Department of Transportation, National Highway Traffic Safety Administration, only has authority over the manufacture and first sale of a motor vehicle. After a vehicle is sold, only state and local governments can regulate the use of motor vehicles.
