Which of the following activities is considered off-duty?

  1. Refueling the vehicle
  2. Loading and unloading goods
  3. Doing routine vehicle maintenance
  4. Spending time in a sleeper berth ✓

Answer: D. Spending time in a sleeper berth

Spending time in a sleeper berth is the off-duty activity.

Why this is the answer

The handbook sets out duty categories and specifically names off-duty time spent in a sleeper berth as one of them. It then lists on-duty work: inspecting, cleaning or repairing the vehicle; loading and unloading; waiting at inspections; and travelling as a co-driver except when in the sleeper berth. Because sleeper-berth time is placed in the off-duty category, it is the choice that fits. Refuelling is not addressed in the passage.

Why the other answers are wrong

Remember it

If you are in the sleeper, you are off duty; if you are loading, cleaning or repairing, you are on duty.
