ABSTRACT:
A deformable elongate upright hollow cylindrical body is formed by a plurality of concentrically stacked tire casings which are bound together by cables. Retaining anchors, each having an eye encircling one of the cables, holds the cylindrical body in a predetermined position to function as a vehicle barrier. Used, empty crushable containers within the hollow body provide additional energy absorption. A barricade wall is fabricated from several deformable bodies, each in tangential contact and secured by additional cables.
