How does a radar speed sign calm traffic and promote safety?
Radarsign’s speed signs give drivers notice that they are speeding. Radar speed signs work by sign shifting the brain out of the alpha state where the brain is aware but relaxed into the beta state where the brain is alert and focused. As a result, the driver responds to the flashing speed alert and slows down. Tests repeatedly show that speeders WILL slow down over 80% of the time when alerted by a radar sign. Typical speed reductions are 10-20%, and overall compliance with the posted speed limit will go up by 30-60%.
