What action should a bus driver take after unloading students?

Answer: B — Close the door and check mirrors before departing

A bus driver should always prioritize safety when operating a school bus. After unloading students, the most important step is to close the door and check mirrors before departing. This ensures that the driver has a clear view of their surroundings, including any students who may be in the immediate vicinity. Checking mirrors helps confirm that no one is left behind, and that it is safe to continue driving. Driving away quickly can lead to dangerous situations where children might still be near the bus. Taking the time to ensure the area is clear demonstrates a commitment to safety. Additionally, although checking for forgotten belongings may seem considerate, it can divert attention from the critical task of ensuring that all students are out of the way of the bus before departing. Waiting for further instructions may not be necessary unless specific protocols are in place at a school; in most scenarios, the bus driver is responsible for ensuring a safe departure.
