Radar speed signs instantly display a driver's speed, serving as a visual reminder of their current speed compared to the posted limit. This helps drivers become more aware of their actions and encourages them to reduce speed.

Permanent radar speed signs, also called driver feedback signs, are post-mounted signs installed on the side of the road that use radar to sense an oncoming vehicle's speed and display that speed back to the approaching driver.

Radar signs flash speeds digitally, displaying the speed of approaching vehicles in realtime. Flashing speed signs remind drivers of posted speed limits. Studies show radar speed signs produce 10-20% reductions in average roadway speeds, and long-term increases in compliance with speed limits.

Radar speed signs, also known as speed feedback signs or speed limit signs, have a straightforward but essential mission: they serve as visual reminders to slow down. Most radar speed displays don't come equipped with built-in cameras. Instead, they rely on radar sensors to accurately measure your vehicle's speed.
