Abstract
A wheel chocking device having a wheel chock that can be raised from a retracted position to a raised position. In the retracted position, the wheel chock is substantially flat, thereby allowing a truck to be driven over the wheel chock. In the raised position, the wheel chock can be engaged with the wheel of a truck to prevent the truck from driving away from a loading dock. As the chock is moved from the distal position, the chock can raise from a lowered position to an intermediate position. The chock is then moved toward the vehicle wheel. Upon contact with the wheel, the chock will raise from the intermediate position to the fully raised position. In another embodiment, the chock can be inserted laterally from the side of the wheel.
