What is the danger associated with applying the handbrake (parking brake) when the vehicle is moving?

Correct Answer

The wheels could lock and cause the vehicle to skid.

Explanation: Except in an emergency; the handbrake (parking brake) should never be used when the vehicle is moving. This practice is potentially dangerous; as the wheels could lock up and the vehicle could skid out of control. In addition there is no warning to following traffic from the brake lights.
