Radar speed signs have been proven to be highly effective in calming traffic and reducing the likelihood of fatal accidents involving pedestrians and automobiles. Studies consistently show that slowing down traffic significantly decreases the chances of severe outcomes. For instance, a pedestrian struck by a car at 40 mph faces a staggering 90% fatality rate, whereas at 20 mph, the fatality rate drops drastically to just 10%. The accompanying graph underscores the profound impact that even a minor reduction in speed can have on the survival outcomes for those involved in such incidents.
Radar speed signs stand as a tried-and-true solution for promoting speed awareness among drivers. Studies consistently highlight their efficacy, revealing that drivers, when alerted by a radar sign, exhibit a substantial reduction in speed up to 80% of the time. On average, radar signs contribute to typical speed reductions ranging from 10% to 20%, leading to an impressive overall compliance increase of 30-60% with posted speed limits. Radar signs are particularly effective at getting “super speeders”—speeders driving 20 mph or more over the posted speed limit—to slow down..
