ABSTRACT:
A collapsible road barrier comprises a foundation pit, a frame located in the foundation pit, an expandable barrier element mounted in the frame, at least one energy absorption element extending from a rear wall of the foundation pit to a rear side of the frame, and at least one stretching element connected between the front side of the frame and the front wall of the foundation pit, such that vehicle impact against the barrier element will cause the frame to first move towards the rear wall of the foundation pit, causing the energy absorption element(s) to compress and the stretching element(s) to extend and eventually break, and then pivot upwardly to stop the vehicle.
