This definition shall include two classifications: Type A-I, with a Gross Vehicle Weight Rating (GVWR) less than or equal to 10,000 pounds; and Type A-II with a GVWR greater than 10,000 pounds. Sixteen passenger or less may be single rear wheeled; 17 passenger and larger shall be dual wheeled.

METROPOLITAN SCHOOL BUS TYPEB

A Type "B" school bus is a conversion or body constructed and installed upon a van or frontsection 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.

CONVENTIONAL SCHOOL BUS TYPEC

A Type "C" school bus is a body installed 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. The entire engine is in front of the windshield and the entrance door is behind the front wheels.

TRANSIT SCHOOL BUS TYPED

A Type "D" school bus is a body installed 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.
