What safety procedure should be followed when backing up the bus?

Using a spotter or ensuring the area is clear when backing up the bus is essential for safety. This practice helps the driver maintain awareness of their surroundings and ensures that there are no obstacles or pedestrians in the path of the bus. A spotter can provide guidance and assist in monitoring blind spots, which are particularly challenging for large vehicles like buses. By adopting this method, the likelihood of accidents or collisions is significantly reduced.

In contrast, backing up quickly does not allow for careful observation and increases the risk of hitting something or someone. Relying solely on mirrors can also be inadequate due to blind spots that larger vehicles have; thus, visual checks around the bus are crucial. Additionally, turning off the engine before backing up is unnecessary and can be impractical since the bus may require power for essential systems, such as brakes and lights, which need to be operational while maneuvering.
