3M Traffic Safety Systems has introduced a Driver Feedback Sign that is proven to improve road safety in high-risk areas. The new, larger 3M “highway” driver feedback sign is specifically designed for use on higher speed roadways and is a permanent solution for a permanent problem. Compared with the smaller driver feedback sign, the larger sign with its increased range and visibility is a great choice for high speed applications. It has a built-in radar speed detection combined with an attention-grabbing display designed to detect vehicles from as far away as 1,500 feet, and is a proven traffic-calming tool that helps improve road safety.
