The MPH Speed Monitor IV controls speeding in the most citizen-friendly way. Since speeds are reduced without issuing citations, the MPH Speed Monitor 4 can generate positive feelings in the general public. Drivers have confidence in the accuracy of the sign because it employs MPH's exclusive Approach-Only radar, which eliminates false speeds generated by opposite direction traffic. Since no training is required to use the sign, it can be used by schools, community organizations, or any group interested in reducing speeds. The MPH Speed Detector is weatherproof, weighs only 14 pounds, and has no moving parts, giving it maintenance-free service and longevity.
