Driving in the Midwest. Driving in Iowa, Nebraska, the Dakotas or Minnesota during the winter months should always be done with care, especially during a weather event. Ice can occur on bridges due to cooler temperatures on the bridge pavement than on surrounding streets and should always be approached with care. Many times melting snow and ice during the day can freeze at night causing very slippery conditions on roadways. Snow can become slick on roadways, especially during snows at near freezing temperatures.
Deep snow can cause a motorist to become hung up where the tires no longer touch the ground.
In these situations it is highly advisable to either pull off to the side of the roadway or leave the roadway as quickly as possible. Black ice is one of the most dangerous forms of ice in that it is virtually invisible, especially at night. Fine mist or fog can generate black ice. Stranded on a Roadway. In the event a motorist gets stranded on the roadway the person should remain in the vehicle and only operate the vehicle for a few minutes to warm up the vehicle and then keep it shut off for 20 minutes.
