Abstract of the Disclosure An improved vehicle restraint for preventing movement of a vehicle, such as a truck away from a loading dock during a loading operation. The vehicle restraint includes a guide frame mounted on the front face of the loading dock and a hook is disposed to move vertically on the guide frame between a lower inopera- tive position and an upper operative position where the hook engages an abutment on the vehicle. The hook is moved between the inoperative and operative positions by a fluid cylinder assembly, including a cylinder which is disposed in a recess in the driveway adjacent the loading dock, and the piston rod of the fluid cylinder assembly is connected to the hook. By intro- ducing fluid into the lower end of the cylinder, the piston rod will be extended to move the hook to the operative position. The compressible nature of the fluid in the cylinder enables the hook to follow rising and falling of the truck bed during the loading operation.
