What is the role of mirrors on a school bus?

The role of mirrors on a school bus is crucial for ensuring the safety of the children being transported as well as for the overall safety of the road environment. Mirrors are strategically placed to allow the driver to have a comprehensive view of their surroundings, including blind spots and the areas directly adjacent to the bus. This extended visibility is essential for monitoring passing traffic, ensuring that the driver can see vehicles or pedestrians that may be approaching from different directions. By effectively using the mirrors, the driver can make informed decisions, such as when to stop or proceed, especially at bus stops where children may be getting on or off the bus.

The other functions mentioned in the choices do not contribute to the safe operation of the bus in the same way. Monitoring the inside of the bus, checking fuel levels, or assisting in navigation, while important tasks, do not rely on the mirrors and do not address the key safety concerns that arise from the bus’s size and its interactions with surrounding traffic. Mirrors directly enhance situational awareness, which is vital for safe driving and protecting the children on board.
