The Wisconsin Department of Transportation and its Division of State Patrol ask Labor Day holiday travelers to buckle up, stay alert and be prepared for slower traffic in work zones and along major travel corridors. Peak travel periods are expected between noon and 8 p.m. Aug. 30 and during the same time frame on Labor Day, Sept. 2.

For the safety of motorists and workers, construction on most highway projects will stop by noon on Aug. 30 and will not resume until 6 a.m. on Sept. 3. Still, drivers are asked to be alert for work zones, lane restrictions and potential delays. During last year’s Labor Day holiday weekend in Wisconsin, traffic crashes resulted in seven fatalities and 355 injuries, according to the DOT.

Law enforcement agencies across Wisconsin are working in greater numbers for longer hours as part of the Drive Sober or Get Pulled Over campaign that continues through Labor Day. Important safety tips for travelers:

  • Buckle up, slow down, eliminate distractions. On interstates and other multi-lane highways, keep right to the extent possible and don’t linger in the passing lane.
  • Move over or slow down when approaching emergency responders, such as police and fire vehicles, ambulances, tow trucks and highway maintenance vehicles, that are stopped along a highway with their warning lights flashing.
  • Before heading out, ensure that trailers and any cargo are properly secured. If your vehicle breaks down, try to get safely off the highway. Remain buckled up in your vehicle and wait for help to arrive.
