Which types of mirrors must be installed on school buses?

The correct answer is that overhead and crossover mirrors must be installed on school buses to ensure the safety of the students being transported. Overhead mirrors provide the driver with a view of the area around the bus, particularly of the students who may be boarding or disembarking, helping the driver monitor for any potential hazards. Crossover mirrors are specifically designed to allow the driver to see areas on the side of the bus where children might be, including those in the “danger zone,” the space immediately around the bus that is difficult to observe otherwise. These mirrors play a crucial role in reducing blind spots and enhancing the overall safety of school bus operations by improving visibility in critical areas where children are present.

While side and rearview mirrors, as well as convex and regular mirrors, can also contribute to visibility, the overhead and crossover mirrors are specifically mandated due to their unique function in a school bus environment.
