1. In a system for providing protection during impact against highway crash barriers of the type comprising horizontally extending rails adapted to be supported along a roadway by attachment to vertical supporting posts anchored in the ground, the improvement comprising: a cladding complex comprising a plurality of planar surfaces arranged in the form of concentric rings adapted to extend along the height of said supporting posts and having their opposed ends terminating in a housing structure which engages opposed sides of each post, the housing structure having an open end to allow it to be attached to said posts, the concentric rings extending outwardly from the post in the direction of the roadway beyond the roadway facing side of the post, the concentric rings each having a thickness that decreases progressively from their ends which attach to the housing to reach a minimum thickness at their central portions which extend from the post in the direction of the roadway.
