An energy absorbing barrier for dissipating kinetic energy upon impact by a moving vehicle. The barrier comprises walls defining a container closed except for a fill opening to admit water. Various configurations of side walls are disclosed. The side walls are resiliently deformable to return to their original shape after being struck, the resilience of the walls and their deformability tending to form a capture region adjacent the vehicle tire which tends to slow the tire and prevent it from climbing and vaulting the barrier. In one embodiment the walls include longitudinally extending, vertically spaced apart traction spoiler channels to reduce the area of contact between the barrier and the tires of a vehicle. Other embodiments include fittings for end coupling of a barrier to like barriers, the fittings permitting adjacent barriers to be located at different heights to accommodate gradual changes in terrain elevation. Other fittings are shown which enable arrangement of end coupled barriers in curvilinear and other configurations.

An energy absorbing barrier for dissipating kinetic energy upon impact by a moving vehicle, said barrier comprising: an elongate container having walls, including a pair of longitudinally directed side walls, defining an interior chamber having a fill opening for admitting fluent material into said chamber, said container being configured and constructed of a material having a rigidity sufficient for said container to retain its shape both when said chamber is empty and when it is filled with said fluent material whereby said barrier is adapted to serve both as a self-supporting lightweight barrier and as a heavier barrier, respectively, said material further having a resilience sufficient to deform upon impact by a vehicle and recover its shape after said impact whereby an impacted one of said longitudinally directed side walls is adapted to progressively deform along its length as the impacting vehicle travels along said length, thereby progressively slowing said vehicle.
