Rumble strips in Wisconsin

  • More than one-third of Wisconsin fatalities have been due to roadway departure crashes, with 90 percent occurring in rural areas.
  • To reduce the number and severity of roadway departure crashes, or run-off-the-road and cross center line crashes on undivided roads, Wisconsin Department of Transportation (WisDOT) goals are to keep vehicles on the roadway, enable a safe recovery to the driver lane, and reduce the severity of crashes that occur.
  • Center line and shoulder rumble strips are proven, cost-effective prevention measures, by alerting drivers via noise and vibration when they drift from the driving lane, allowing them to readjust their driving.
  • The installation of center line and shoulder rumbles along 2-lane, rural, asphalt, high speed State highways began in 2012. Since then WisDOT has continued to install center line and shoulder rumbles on this facility type.
  • Beginning in the 2014 construction season and after asphalt, 2-lane rural State highways with at least a six-foot total shoulder width will receive a 5-foot paved shoulder and shoulder rumble strips on reconstruction, pavement replacement and new construction projects.
