Radar Speed Signs, or also known as Driver Feedback Signs, are designed to slow speeders down by alerting them of their speed through a digital display board. Ultimately, the use of Radar Speed Signs makes the roads safer for pedestrians and drivers. Due to their effectiveness as a Traffic Calming Device, they are being used across the country and the world. There have been tests performed that consistently show that Speeders will reduce their speed the majority of the time, and overall compliance with the posted speed limit will increase.
