Why should mirrors on a school bus be adjusted correctly?

The mirrors on a school bus should be adjusted correctly primarily to provide maximum visibility around the bus. This is crucial for the safety of both the students on board and other road users. Properly adjusted mirrors allow the driver to see blind spots, track the movements of pedestrians, particularly children, and monitor the surrounding traffic effectively.

Having optimal visibility helps in making informed driving decisions, reduces the risk of accidents, and ensures that a driver can respond quickly to any potential hazards. This adjustment is specifically important for large vehicles like school buses, which have considerable blind spots due to their size.

While aesthetic appeal, compliance with regulations, and wind noise might play roles in vehicle design and operation, the primary function for adjusting mirrors is safety through visibility.
