Mounted arrow boards are highly effective traffic control devices designed to enhance road safety, particularly in construction zones, detours, and emergency situations. These portable boards feature bright, illuminated arrows that guide drivers and direct traffic flow, ensuring smooth and safe navigation through hazardous areas. Mounted on vehicles or trailers, they can be quickly deployed and easily adjusted to display different directional signals. Arrow boards are a vital tool for improving visibility, minimizing traffic congestion, and reducing the risk of accidents by clearly indicating lane changes, road closures, mounted arrow boards or diversions.
