The first raising/lowering arm mechanically coupled to and supporting an upper portion of the net via a first upper frangible tensioner and mechanically coupled to and supporting a lower portion of the net via a first lower frangible tensioner. A second raising/lowering arm arranged on another side of the roadway, the second raising/lowering arm mechanically coupled to and supporting an upper portion of the net via a second upper frangible tensioner and mechanically coupled to and supporting a lower portion of the net via a second lower frangible tensioner. The first and second upper and first and second lower frangible tensioners decouple from the net upon application of a predetermined force.
