Abstract
Wheel restraints for restraining vehicles at loading docks are described herein. An example wheel restraint includes a restraining arm to anchor a wheel chock to a fixed point at the dock. When in a blocking position, the chock rests directly upon the dock's driveway without the chock having to engage additional hardware that could be an obstruction to snow removal. In some examples, the wheel chock automatically swings between its blocking and release positions in response to the arm simply lowering or raising the chock.
