How do I use a wheel chock?

Using a wheel chock is straightforward: Park the vehicle on a level surface and engage the parking brake. Choose the appropriate size and type of wheel chock for the vehicle or trailer. Place the wheel chock snugly against the tire of the vehicle, on the side opposite to the direction of intended movement. Ensure that the wheel chock makes firm contact with the tire and the ground, providing stability and resistance against rolling. Check that the wheel chock is secure and does not move or shift when pressure is applied to the vehicle.
