A Type "A" school bus is a conversion or TYPE A body constructed upon a van-type or cutaway front-section vehicle with a left side driver's door, designed for carrying more than 10 persons. This definition shall include two classifications: Type A-I, with a Gross Vehicle Weight Rating (GVWR) of over 10,000 pounds; and Type A-II with a (GVWR) of 10,000 pounds and under. Sixteen passenger or less may be single rear wheeled; 17 passenger and larger shall be dual wheeled.
A Type "B" school bus is a conversion or TYPE B body constructed and installed upon a van or front-section vehicle chassis or stripped chassis, with a gross vehicle weight rating of more than 10,000 pounds, designed for carrying more than 10 persons. Part of the engine is beneath and/or behind the windshield and beside the driver's seat. The entrance door is behind the front wheels.
A Type "C" school bus is a body installed TYPE C upon a flat-back cowl chassis and has a gross vehicle weight rating of more than 10,000 pounds, designed for carrying more than 10 persons. All of the engine is in front of the windshield and the entrance door is behind the front wheels.
A Type "0" school bus is a body installed TYPE 0 upon a chassis, with the engine mounted in the front, midship, or rear, and has a gross vehicle weight rating of more than 10,000 pounds, designed for carrying more than 10 persons. The engine may be beside the driver's seat; it may be at the rear of the bus, behind the rear wheels, or midship between the front and rear axles. The entrance door is ahead of the front wheels.
