Abstract: A guardrail system including a sled designed to absorb the impact of a vehicle is disclosed. The sled forms part of the terminal portion of the guardrail system. The terminal portion of the guardrail system also includes one or more cables that are anchored to the ground and pass through the sled. The sled supports a cable break that is in engagement with the cable. The sled is supported by a releasable post that is released from its base upon the impact of a vehicle. The cable or cables extend for some distance from the sled along the guardrail system. Once the post supporting the sled is released from its base due to the impact of a vehicle, the sled can move along the cable with the friction between the cable brake and the cable gradually dissipating the energy from the impact.

Abstract: A cable integrated guardrail system for highway guardrail. The rail of the system contains at least one cut section placed longitudinally along the panel, and of sufficient dimension as to allow interaction with a cable. Said cut sections also act to reduce longitudinal resistance and safely stop axially impacting vehicles. A cable, which is of sufficient length to extend longitudinally along the entire system, prevents tearing of the rail during lateral impacts and aids in safely redirecting the vehicle away from a hazard.
