Immediately after stopping, what should a school bus driver do?

When a school bus driver stops, one of the initial actions that should be taken is to open the entrance door slightly. This is crucial for signaling to pedestrians and students that the bus is in the process of loading or unloading passengers. Opening the door provides a visual cue that the bus is stopped and that it is safe for students to approach or leave the bus, particularly when they may be in the vicinity.

This action aligns with safety protocols designed to protect children who might be entering or exiting the bus. By doing so, the driver also creates a clearer view for themselves of the immediate surroundings, helping to ensure that no one is in danger as they proceed with the loading or unloading process. This step is vital for maintaining a safety-first environment during these critical moments.

While the other options could be relevant in different contexts—like turning off the engine, activating hazard lights, or checking rearview mirrors—opening the door slightly is specifically geared towards managing the safe boarding and disembarking of students.
