An end terminal assembly of a highway guardrail system to enhance safety of a vehicle impacting an end of the guardrail facing oncoming traffic. The guardrail system includes a W-beam type guardrail mounted on a plurality of posts adjacent to the side of a highway. The guardrail includes at least one W-shaped beam having a first edge curl and a second edge curls. A kinetic energy absorbing assembly is integrally engaged with the one end of guardrail to stretch portions of at least one W-shaped beam to dissipate energy from an impacting vehicle. An anchor assembly may be provided as part of the end terminal assembly to provide tension support as desired for the guardrail during rail face impacts and a cable anchor bracket which releases from the guardrail during a head on impact with the end of the guardrail.
