What actions should you take to park and secure a bus after completing a route?

• A. Turn off the engine but leave the doors open.
• B. Leave the engine running and remove keys at the same time.
• C. Park, set transmission to neutral, and leave the engine running.
• D. Engage parking brake, idle engine off, remove keys, ensure doors are closed, and verify all pupils have disembarked.

Answer: (D)

After finishing a route, the priority is to secure the bus and ensure all pupils have disembarked. Engage the parking brake to prevent the bus from moving, turn off the engine to stop idle running, remove the keys to prevent unauthorized use, make sure the doors are closed to secure the interior, and verify that every pupil has left the vehicle. This sequence protects safety, security, and accountability. Leaving the engine running, doors open, or skipping the check on pupils creates avoidable hazards.
