What is the correct procedure to prepare to leave after loading or unloading students?

The correct procedure involves releasing the parking brake and signaling left before departing. After loading or unloading students, it is essential for a bus driver to ensure the safety of all passengers and other road users.

Releasing the parking brake indicates that the bus is prepared to move. Signaling left is crucial as it communicates to other drivers that the bus will make a left-hand turn or maneuver into that lane. This sequence emphasizes the importance of clear communication about the bus's intended movements to ensure the safety of students exiting or entering the vehicle and to maintain awareness of surrounding traffic.

Other choices may involve steps that do not align with best practices for safety. For example, turning off the bus before preparing to leave may cause confusion about readiness for movement, while checking mirrors and driving off directly may neglect the critical step of signaling, which is vital for maintaining safety and awareness among other road users.
