The Federal Highway Administration (FHWA) has mandated the use of alternatives to W-beam guardrail terminals, with the objective of eliminating the 'ramping' action that would send a vehicle airborne when it collided with the buried end of a guardrail, thus increasing the severity of the accident. The article describes the system installed in Oklahoma which consists of fender panels, support posts with slip bases, and sand-filled boxes that dissipate the energy of an impact, and safely shield the beginning of the standard guardrail section. The system used in Oklahoma uses a unique system of telescoping panels plus a redirecting cable. The treatment gently guides an impacting vehicle away from the hard spot. Upon impact the fender panels telescope to safely decelerate and redirect the errant vehicle.
