Abstract
Various example vehicle restraints for use at a loading dock for blocking and later releasing a vehicle's rear impact guard. In some examples, the vehicle restraint includes a hook-shaped barrier that rotates between a lowered position and a raised position. The barrier rotates up to block the rear impact guard and rotates down to release it. The barrier also translates or shifts forward and back between a retracted position and an extended position. The barrier shifts forward to relieve forward pressure that the vehicle might exert against the barrier just prior to releasing the rear impact guard.
