When is it most critical to check the mirrors before driving a school bus?

Checking the mirrors before operating the bus is essential for ensuring safety and proper visibility. Mirrors provide the driver with a view of the surrounding area, which is crucial for detecting any obstacles, pedestrians, or vehicles that may not be directly in front of the bus.

This pre-operation check allows the driver to adjust the mirrors appropriately for their height and position, ensuring that they have optimal visibility of the bus's blind spots. Being aware of the environment around the bus before starting to drive helps to prevent accidents and ensures a safe experience for both the driver and the students.

While it is also important to check the mirrors during other times, such as after students have boarded or while on the route, the initial check before operating the bus sets the stage for safe driving practices from the moment the bus begins to move. It emphasizes the critical nature of visibility right from the start, which is especially vital in a school bus setting where the presence of children increases the risks involved.
