1. Speed feedback

A speed feedback system (also called a radar speed sign or driver feedback sign) is an electronic sign that shows your current speed as you drive past it. It uses a radar sensor to detect how fast you're going. Then it displays your speed in real time on a digital screen to make drivers aware of their speed.

  • Your speed in green if you're within the limit.
  • Your speed in red if you're going too fast.
  • Messages like "Slow Down!" or "Thank You!" depending on your speed.
  • Studies show it can reduce speeding even without police or fines.
  • Can collect speed data for traffic studies.
