How should a bus driver use the mirrors during normal driving?
Correct answer: D – Check regularly as part of the driver’s continuing traffic scan
Drivers should check their mirrors regularly to remain aware of vehicles beside and behind the bus. Mirrors help identify overtaking traffic and vehicles moving into blind spots. Lane changes, turns, merges, and tight maneuvers require additional checks beyond the driver’s normal scanning routine.
