What is one key purpose of the convex mirrors on a school bus?

Convex mirrors are strategically placed on school buses to provide a wider field of view to the driver. This design feature is crucial for enhancing safety, as it allows drivers to see areas that would be blind spots when using standard mirrors. The increased visibility helps the driver monitor the surroundings, including pedestrians, cyclists, and vehicles that may be in close proximity to the bus, ultimately supporting safer driving conditions, especially when loading and unloading students.

Enhancing the aesthetic appeal, reducing sunlight glare, or assisting with passenger comfort do not capture the primary safety function that convex mirrors serve on school buses. Their main role is to optimize visibility and ensure that drivers maintain awareness of their environment, crucial for the safety of both the children and other road users.
