Chock
AKA: Wheel Chock
WARNING:
Before releasing the parking brake, make sure your chock is firmly wedged between the ground and the tire and that the ground is solid enough to maintain the pressure of the vehicle. Loose or soft ground are not ideal surfaces for chocking wheels.
Never use a damaged chock, as it may not hold as expected, and the vehicle could roll away.
