Hazard Markers

Hazard markers are ideal for marking obstructions within or adjacent to the roadway. These vertical panels work well to alert drivers of bridge and culvert approaches, easily missed end treatments, and other hazards that may not be immediately apparent to a fast-approaching motorist. They provide high-target value and are often mounted to the top of bridge guardrails and placed at low-water crossings to help create driver awareness of potential hazards.

Hazard markers are available in single or double-sided versions and come standard with our patented anti-twist reactive spring assembly that returns the panel to its original position after impact to ensure product longevity and reduced replacement costs.
