Wheel positional restraint device and method for using the same

A multi-tiered assembly (77) of leveler units (60) with a vehicle wheel positional restraint (70) is provided. The leveler units each comprise a planar body, with upper and lower surfaces circumscribed by edges. The body of each unit bears a plurality of pins (62) upwardly extending from the upper surface and has a plurality of pockets (64) formed in the lower surface to receive corresponding pins of other similar units. The pins are of slightly smaller size than the corresponding pockets. The positional restraint (70) can interlock with the other leveler units (60) and additionally provide an upper surface (72) with an obstruction (80) to prevent wheel (4) movement.
