Abstract

In accordance with a particular embodiment of the present invention, a guardrail safety system includes a guardrail beam having a length-of -need (LON) portion spanning between two terminal portions. The guardrail safety system also includes a plurality of guardrail support posts in spaced apart relation to one another. At least a portion of the plurality of support posts include a lower portion for installing below grade adjacent the roadway, a mid portion that lies substantially adjacent the grade, and an upper portion releasably coupled to the LON portion of the guardrail beam. The mid portion includes a weakened section operable to weaken the support post about a first axis without substantially changing the behavior of the support post about a second axis that is generally perpendicular to the first axis.
