What is the definition of a school bus?
A school bus is a vehicle that is sold or introduced in interstate commerce for purposes that include carrying students to and from school or related events, but does not include a bus designed and sold for operation as a common carrier in urban transportation.A school bus can be used to carry non-students, if local rules allow it, usually with the requirement that school bus signs and warning lights not be used. But a normal everyday transit bus or shuttle bus cannot be used to carry school children. Such buses do not have any of dozens of safety features required on a school bus, such as joint strength, roof strength or compartmentalized seating.
The term school bus when used in sections 302.010 to 302.540, RSMo, means any motor vehicle, either publicly or privately owned, used to transport students to and from school, or to transport pupils properly chaperoned to and from any place within the state for educational purposes (302.010, RSMo).
