Roadside safety hardware redirects vehicles that leave the roadway away from roadside hazards such as steep drop offs, bodies of water, or the roadside itself, which may be lined with fixed objects such as trees, bridge piers, retaining walls, or utility poles. Highway engineers carefully weigh the placement of roadside safety hardware, and in most cases, these devices work extremely well.
