The Type D school bus is a transit style vehicle with its body installed on a chassis. The engine can be mounted in the front, mid-ship, or in the rear. It has a gross vehicle weight rating of more than 10,000 pounds and designed for carrying more than 10 passengers. The entrance door is ahead of the front wheels.
There are three Type D buses:
RE – Rear Engine – the engine is installed in the back and the nose of the school bus will be flat and will hold 66-84 passengers. It looks like a Recreational Vehicle and will be quieter. It has a longer wheel base due to the engine being mounted on the back and can have storage underneath.
FE – Forward Engine – will hold 54-90 passengers. This bus is used in densely populated or high traffic areas.
FC – Forward Control – is a school bus with the steering wheel, pedals, instruments, and other driver controls mounted as far forward as possible, usually just behind the windshield. All of the engine is either located behind the windshield at the front of the bus, at the rear of the bus, or somewhere in between these positions. The service door is located forward of the front axle.
A Type D school bus has a maximum length of 45 feet.
