2025 National Work Zone Awareness
National Work Zone Awareness Week (NWZAW) is an annual spring campaign held at the start of construction season to encourage safe driving through highway work zones. The key message is for drivers to use extra caution in work zones. National Work Zone Awareness Week was observed April 21-25, 2025. The theme for 2025 is "RESPECT THE ZONE SO WE ALL GET HOME". Please use extra caution around work zones.
Work Zone Safety
Each year in Wisconsin, both highway workers and motorists are killed and injured in crashes that happen in highway construction zones. Motorists should slow down, be patient and pay attention to their surroundings in all work zones.
For more information regarding work zone rules for motorists, the law restricting hand-held devices, and general work zone safety information, please see WisDOT's work zone safety website. To help safeguard law enforcement officers, emergency responders, road maintenance workers, and others who work on the side of the highways, Wisconsin has a "Move Over Law" (Wis. Stat. s. 346.072) stating that drivers must provide a safety zone for stopped law enforcement, emergency and maintenance vehicles.
The law requires drivers to shift lanes or slow down in order to provide a "safety zone" for a squad car, ambulance, fire truck, tow truck, utility vehicle, or highway maintenance vehicle that is stopped on the side of a road with its warning lights flashing.
Drivers have two options for creating a safety zone:
If the road has more than one directional lane, like the Interstate, and you can switch lanes safely, you must move over to vacate the lane closest to the law enforcement or other vehicle with its lights flashing.
If the road has a single directional lane or you can't safely move over, you must reduce your speed.
Failure of motorists to move over is one of the reasons that motor vehicle crashes kill more law enforcement officers on duty than any other cause.

The Winnebago County Highway Department values their employee's lives, we sincerely hope that you do too. Every employee has family waiting at home for them each evening. Please drive accordingly!
