If you must leave the vehicle to assist a pupil, you must ?

• A. First secure the emergency brake, shut off the engine, and remove the key
• B. Shut off the engine, then proceed to assist the pupil
• C. Secure the emergency brake, then proceed to assist the pupil
• D. Secure the emergency brake, shut off the engine, then proceed to assist the pupil

Answer: (A)

When you must leave the vehicle to assist a pupil, the priority is to immobilize the bus and prevent any movement. Engaging the emergency brake first locks the wheels, so the bus can’t roll away while you’re out of the cab. Next, turning off the engine reduces the risk of unexpected movement and stops exhaust or heat buildup. Finally, removing the key prevents anyone from starting or moving the bus in your absence. This combination keeps students safe by making sure the vehicle can’t move and can’t be used when you’re not inside. The other options miss one or more of these critical safety steps, which is why they’re not the best choice.
