Duluth, MN (NNCNOW.com) --- A section of I-35 in Duluth has been limited to one lane due to car crashes and the difficult driving conditions across the Twin Ports. According to officials at the Minnesota Department of Transportation, the south bound lane of I-35 between 21st Avenue East and 26th Avenue East has been limited to just one lane. The Minnesota State Patrol says that between 6 A.M. and 11:50 A.M. Friday morning, their officers had already responded to 21 property damage crashes, one minor crash injury and at least 12 vehicles driving off the road. On the Minnesota 511 Travel Information site, most major roads in Duluth are listed as difficult for driving. Just south of Duluth, I-35 is listed in fair condition. The Minnesota Department of Safety gives these tips on making sure you don't end up in a car crash: * Buckle up, and make sure child restraints are secured tight enough. It is recommended to have bulky winter coats and blankets on top of the child restraint harness, not beneath, to ensure harness restraints fit properly. * Drive at safe speeds according to road conditions, and allow plenty of travel time. * Increase safe stopping distance between vehicles. * Use extra precaution around snowplows — keep at least five car-lengths behind plows. * If skidding — ease foot off the gas and turn the steering wheel in the direction you want the front of the vehicle to go. * If vehicle has an anti-lock braking system (ABS), apply a steady firm pressure to the brake pedal. Never pump ABS brakes. * Clear snow and ice from vehicle windows, hood, headlights, brake lights and directional signals. * Headlights must be turned on when it is snowing or sleeting. * Do not use cruise control on snow/icy/wet roads. * Move over for emergency responders on the shoulder of the road — it’s the law. * Parents of teen drivers should make sure new motorists experience snow and ice driving in a safe environment, such as an empty parking lot. Safety officials also suggest making sure you have a winter survival kit in your car at all times that include a scraper/brush, small shovel, jumper cables and a bag of sand or cat litter for tire traction. Blanket(s), boots, warm clothing, a bright cloth to tie on an antenna or hang in the window to signal for help and flashlights are also important, as are high-energy foods such as chocolate or energy bars. Snow is expected to continue to fall in the Twin Ports into the early afternoon. Posted to the web by Krista Burns
