Abstract

A force-absorbing barrier 10 includes a plurality of concentric chambers 21, 23, 25 and 27 at least partially filled with fluid 42. The walls 22, 24, 26 and 28 defining the chambers are flexible. Fluid passages 30 in the interior walls 24, 26 and 28 between chambers allow fluid flow between the chambers. The fluid flow from chamber to chamber will absorb energy from the impact a motor vehicle, preventing the vehicle from impacting the terminal of a guardrail.
