What is the entrance door location for a Type "B" school bus?

The entrance door location for a Type "B" school bus is located behind the front wheels. This configuration is designed to enhance the safety of children entering and exiting the bus. By placing the door behind the front wheels, it helps to minimize the risk of accidents caused by cars passing the bus, as the door opens away from the front of the vehicle.

This design feature allows greater visibility for the bus driver when students are boarding and disembarking, ensuring that they can safely monitor the area around the bus. Furthermore, having the entrance door in this position allows for more space for the driver and students to operate without being in close proximity to the roadway.

The other options suggest door locations that either compromise safety or do not align with the standard specifications of a Type "B" bus. For instance, having the door ahead of the front wheels would place students at higher risk of coming into contact with oncoming traffic, while positioning the door in the middle of the bus could complicate boarding logistics and safety protocols. The specification of the right side as an entrance point is typical, but the defining characteristic of a Type "B" school bus is its door placement behind the front wheels.
