Abstract
A guardrail includes an array of vehicle-deflecting rails secured to an array of posts extending along a roadway. An impact-receiving element is slidably mounted to the forward end of the array of rails, and this impact-receiving element includes a vehicle-engaging portion having a first frontal area that is substantially greater than a second frontal area characteristic of the first end of the array of rails. A column is interposed between a forward portion of the impact-receiving element and the first post to apply initial compressive forces in a collision directly to the first post.
