Beschreibung
Zusammenfassung:	A roadway guardrail system including a rail and plurality of support posts assembled such that upon impact from a vehicle the rail moves upwardly with respect to the post. Fasteners may be used in the operative coupling of the rail to the support posts, such that upon impact the fasteners move upwardly with respect to the support posts and the rail moves upwardly along with the fasteners. The guardrail system may further include a reinforcing member that is slidable along the post and operatively coupled to the rail with the fasteners, such that the rail and fasteners slide along with the reinforcing member with respect to the support posts. The reinforcing member may be a spacer of various shapes, a washer, an additional rail section, or other type of member that allows the rail to slide upwardly with respect to the post.
