Black ice, the near invisible road hazard, causes winter accidents throughout Minnesota.

MnDOT says black ice forms in a transparent layer when the air temperature is warmer than the road surface. It’s most common at night or very early in the morning due to the extremely low temperatures. The most common spots for black ice to form is near water sources such as lakes and rivers, but it can also occur from vehicle exhaust and vehicle traffic melting the snow on roads, causing them to freeze later.

MnDOT has given some tips to avoid accidents caused by black ice. Driver’s should use a safe speed for winter driving conditions, regardless of the posted speed limit. Also, keep a safe stopping distance from the vehicle in front of you, keep both hands on the steering wheel, don’t use cruise control and avoid applying brakes on ice as it may cause a vehicle to skid.
