When is it required to operate the parking (hand) brake whilst parking?
- Only when the vehicle is parked on a steep descent.
- Correct answer: Always.
- Only when the vehicle is parked uphill.
- Only on a wet road.
Why this is the answer
The correct answer in the official bank: Always.
The parking brake should be applied every time the vehicle is parked, whatever the slope or road condition. Even a road that looks flat may have a slight gradient, and a parked vehicle can roll if it is bumped or vibrates. Limiting it to hills, descents or wet roads is wrong, because the parking brake is a basic safeguard that keeps an unattended vehicle from moving.
