DOT Warns Against Black Ice with Cold Temps

The Wisconsin Department of Transportation would like to remind motorists to be cautious if traveling in what could be hazardous conditions. High winds and drifting snow are expected to make driving very difficult this weekend.

With low temperatures and high winds, there is high potential for black ice, which is almost invisible to the naked eye and is frequently mistaken for a wet or newly paved road. Motorist should watch out for:

  • Pavement that looks dark, wet or like new asphalt.
  • Low-lying areas that may have standing water or run off from nearby melting snow banks or puddles.
  • Bridges and Underpasses.
  • Any road areas which are shaded from the sun.

For areas of the state being impacted, WisDOT advises against travel this weekend, unless absolutely necessary. If traveling, please use the following tips:

  • Clear snow and ice from all windows and lights before driving.
  • Go slow. Remember the posted speed limits are for dry pavement.
  • Leave plenty of room for stopping.
  • Leave room for maintenance vehicles and plows.
  • Use brakes carefully. Brake early. Brake correctly.
  • Watch for slippery bridge decks, even when the rest of the pavement is in good condition.
  • Don't get overconfident in your 4x4 vehicle.
  • Don't use your cruise control in wintry conditions.
