An automatic wheel chocking apparatus for restraining movement of a vehicle away from a loading dock during a loading operation. The apparatus comprises an elongated trough formed in the driveway that extends outwardly from the front face of the loading dock and a wheel chock is mounted in the trough for movement between a storage position, where the wheel chock is located beneath the level of a driveway, and an operative position where the chock extends upwardly above the driveway and is disposed to engage a wheel of a vehicle. The wheel chock is moved between the storage and operative positions by a drive mechanism that is located within the trough and includes a lead screw. A nut is threaded on the lead screw and is connected to the wheel chock via a rigid link. Rotation of the lead screw will move the chock between the storage and operative positions.
