Speedcheck radar speed signs have improved worker safety in Oregon’s Medford city by slowing traffic during road projects.

The Federal Highway Administration said that driving at excessive speeds has caused motor vehicle crashes in work zones, resulting in nearly 1,000 deaths and more than 40,000 injuries each year.

Medford’s public works department decided to use radar speed signs following positive impact on slowing drivers and increase in work zone safety during a one month trial.

Information Display Company loaned the Medford’s public works department a portable display for a one-month trial period.

Medford’s Public Works field operations supervisor Tad Blanton said the effectiveness of the speedcheck radar speed sign was dramatic and immediate.
