What action should a bus driver take while a student is crossing in front of the bus?

The appropriate action a bus driver should take while a student is crossing in front of the bus is to stay alert and observe the crossing. This is crucial for ensuring the safety of the student. By remaining vigilant, the bus driver can monitor the student's movements and respond promptly to any unexpected actions. This includes being aware of potential hazards, such as other vehicles that might be approaching or the possibility of a second student crossing. Staying alert allows the driver to ensure that all students cross the street safely before moving the bus.

Turning off the engine, while it might seem like a precautionary measure, does not address the need for the driver to actively observe the crossing student. Keeping the bus in motion would pose a significant safety risk, as it could endanger the student. Watching from the rearview mirror limits the driver's visibility and reduces their ability to respond effectively to the situation. Therefore, staying alert and directly observing the student as they cross is imperative for maintaining a safe environment.
