MX SeriesTM
SpeedCheck® Radar Speed Signs
Reduce speeds in neighborhoods and school zones with MUTCD-compliant vehicle speed feedback signs (a.k.a. radar speed signs).

Manage speed, save lives
When vehicles speed through urban areas like school zones, residential streets, or roads under 45 mph, pedestrian fatalities skyrocket.
Effective speed management is critical—crash severity increases with vehicle speed and weight. When static signs fail, radar speed signs offer a solution, reducing speeds by 5 to 9 mph and significantly lowering risks to pedestrians.

Proving Radar Speed Signs work
Several studies have examined radar speed signs’ impact on driver behavior in the short and long term. In 2002, the Texas Transportation Institute (TTI) undertook a four-month survey of seven sites where radar speed signs had been permanently installed, including a school zone, sharp horizonal curves, and approaches to signalized intersections. The findings indicated that radar speed signs reduced speeds by 9 mph in school zones within a week of installation, with this effect sustained for four months.
