Before you drive your vehicle, you should
- sound your horn as a warning.
- walk all around the vehicle to check for obstacles or pedestrians. ✓
- rev up your engine.
- lower your windows.
Answer: B. walk all around the vehicle to check for obstacles or pedestrians.
Before you drive, you should walk all around the vehicle to check for obstacles or pedestrians.
Why this is the answer
The handbook says the pre-trip inspection is meant to confirm your vehicle is safe before you start your trip, and it describes taking a careful walk around the vehicle. A backing-up procedure also says to step out and check the area for hazards and obstacles above, below, and on all sides. That supports walking around before you move. The passages do not mention sounding the horn, revving the engine, or lowering windows as a pre-drive check.
Why the other answers are wrong
- A. sound your horn as a warning. — Sounding your horn is not described in the passages as a pre-drive safety check and does not replace looking around the vehicle.
- C. rev up your engine. — Revving the engine is not mentioned in the passages as a way to check for hazards before driving.
- D. lower your windows. — Lowering your windows is not mentioned in the passages as a check for obstacles or pedestrians around the vehicle.
Remember it
Before you move, make a full circle: look for hazards above, below, behind, and beside the vehicle.
