ABSTRACT:
A motor vehicle traction aid device including a plastic bag containing a sand mixture for insertion under a tire on a drive wheel of a motor vehicle for improving traction on ice, snow or the like. The bag is partially filled with the sand material and includes a foam or sponge rubber tab on one side. The bag is inserted between the driving surface and the tire of the motor vehicle such that the tab engages the tire. Rotation of the wheel toward the driving surface causes the tire to engage the tab, drawing the bag and the sand material under the tire in a rolling action, bursting the bag and dispensing the sand beneath the tire.
