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.
