School Zone Flashing Beacons
The flashing yellow beacon lighting is one of the most effective ways to reduce the speed of vehicles in school zones. On average, drivers travel five to seven miles per hour slower when the flashing yellow school zone lights are present.
Signs, Signals, & Striping
The sign crew manufactures all of the road signs that are posted along county roads. If there is a sign missing, damaged, vandalized, or incorrect, we can put in a work order to have a new one made and replaced.
