A truck leveler includes a low-profile traffic surface that is pivotally mounted to a driveway approach in front of a loading dock. Pivoting the leveler raises a reat portion of a truck or trailer to the height of the dock. The truck leveler has strength, rigidity and accommodates a retractable or repositionable wheel restraint while maintaining its low profile. This is accomplished by virtue of a raised rear beam and two lateral beams that extend above the traffic surface of the leveler. A central beam allows field assembly of the leveler while adding further to the leveler's strength and rigidity.
