The required mirrors on a school bus must provide visibility to the rear of the vehicle for a minimum distance of 200 feet. This specification is crucial for ensuring that the driver can see any potential hazards or pedestrians behind the bus, which is essential for safety when maneuvering the vehicle, particularly during backing up and loading or unloading students.

This distance is established based on considerations for the typical operating environment of a school bus, where children may be present, and the need for drivers to have ample visibility to prevent accidents. By having at least 200 feet of visibility, the driver can react appropriately to any situations that may arise behind the bus, promoting a safer environment for students and others in the vicinity.

Thus, the choice of 200 feet reflects a balanced approach to safety and practicality, ensuring that the driver has critical awareness of their surroundings when operating the bus.
