<p>The barrier (10) dissipating kinetic energy upon impact by a moving vehicle comprises walls (16, 18, 20) defining a container (22) closed except for a fill opening to admit water (26). Various configurations of side walls (20) are disclosed. The side walls are resiliently deformable to return to their original shape after being struck, the resilience, thickness and deformability of the walls tending to form a capture region (72) above and in advance of the vehicle tire to slow the tire and prevent it from climbing and vaulting the barrier.</p> |
