Question 4536

During loading and unloading operations, is it allowed to leave the engine running?

  1. Yes, as long as the parking brake is applied.
  2. Yes, as long as the driver does not move away from the vehicle.
  3. No, under no circumstances.
Show answer and explanation

Correct answer: No, under no circumstances.

You leave the driver’s seat to load or unload, so you must stop the engine, switch off the ignition, and leave the parking brake applied. Staying nearby or only applying the brake is not enough.
