A grating member for use in combination with a wheel chocking system for restraining road vehicles being transported in a transport vehicle is described. The grating member comprises an elongated rectangular deck section having a substantially planar upper support structure formed from connected, equidistantly spaced, perpendicular first and second sets of parallel rods defining therebetween rectangular openings for receiving disengageable wheel chocks. The first set of parallel rods contain upwardly formed portions between each of the second set of parallel rods. The upwardly formed portions define a portion of the upper support structure such that the upper support structure is substantially free of trip hazards and further provides lateral engagement surfaces for arresting studs and clamping teeth of the disengageable wheel chock whereby to prevent lateral movement thereof relative to the grating. The longitudinal rods also provide engagement surfaces for the arresting study of the disengageable wheel chock to prevent longitudinal movement thereof.
