Our radar speed signs provide real-time feedback to drivers, encouraging them to reduce speed and adhere to speed limits, ultimately promoting safer road behaviors and communities. Our studies have shown speed reductions ranging from 15% to 25%, with an impressive up to 85% of speeders slowing down. Our affordable radar speed sign's pricing make them an effective alternative to speed humps, which can impede emergency vehicles, impact cyclists, cause noise pollution, along with other negative aspects.
