ABSTRACT:
A traction/sanding device for a wheeled vehicle provides a traction strip attached at one narrow edge to an inflated, breakable container filled with an abrasive substance. The traction strip defines a package wrapping container which protects the container prior to use, preferably in the form of a cardboard box which is unfolded to extend the traction strip. In use, the strip is placed at the intersection of the tire and the road surface, gripper tabs towards the tire. Tire movement, even if spinning, draws the strip under the tire, pulling the container underneath until the weight of the vehicle breaks the container, spilling the abrasive substance on the ground to give an area of improved traction.
