What mirrors are required for a school bus?

The correct answer is based on the requirement for a school bus to have a set of mirrors that enhances visibility and helps prevent accidents. For a school bus, it is essential to have a Right Flat mirror, an Interior mirror, and a Left Flat mirror.

The Right Flat mirror provides a direct view of the passenger side and helps the driver see any pedestrians or cyclists in proximity to the bus. The Interior mirror allows for monitoring the entire passenger compartment and ensuring that students are safely seated. The Left Flat mirror serves a similar purpose to the Right Flat mirror but focuses on the driver's side, enhancing visibility when changing lanes or making turns. All three mirrors are crucial in providing the driver with comprehensive visibility to maintain safety during operation.

In contrast, the other options either include mirrors that are not necessary or do not meet the specific requirements set forth for school buses.
