Abstract
A force-absorbing barrier includes a plurality of chambers at least partially filled with fluid. The walls defining the chambers are flexible. Fluid passages in the interior walls between chambers allow fluid flow between the chambers. Alternatively, the chambers are filled with structures instead of or in addition to a fluid. The fluid flow from chamber to chamber and/or the deformation of the structures will absorb energy from the impact a motor vehicle, preventing the vehicle from impacting the terminal of a guardrail.
