ABSTRACT:
A guardrail end terminal including a plurality of nested fender panels and a redirecting cable for urging the fender panels laterally in response to an axial impact force. The fender panels are supported on vertical legs which are attached to slip bases and are designed to telescope in response to an axial impact force. The redirecting cable is designed to pass through the leg of the first panel and extend away from the leg at an acute angle. The panel legs and cable cooperate to direct the nose of the impacting vehicle away from the unyielding guardrail while at the same time dissipating the energy of the vehicle.
