The Indiana Department of Transportation is preparing for a winter storm expected to impact the state starting overnight Tuesday and early Wednesday.

The National Weather Service has issued winter storm warnings and winter weather advisories for all of Indiana.

INDOT will be at a full call in most areas, with nearly 1,000 trucks treating and plowing state highways, interstates, and U.S. routes by early Wednesday. Trucks will remain active for the duration of the storm and afterward to continue cleanup efforts.

Road conditions will vary depending on location. Impacts on the morning and evening commutes on Wednesday are expected. INDOT’s goal is to keep highways passable during the storm. 

Motorists should closely monitor forecasts and avoid unnecessary travel during higher-impact timeframes during the storm, which is anticipated during the day on Wednesday. Those who must travel should expect to encounter slush and snow-covered roads, as well as low visibility.

Snow showers will linger through Thursday, with a high likelihood of lake-effect snow in northeast Indiana. Drivers should remember to slow down, increase the following distance, give plow trucks room to work and allow plenty of extra time to reach their destinations.

Monitor real-time travel conditions and view traffic and snow plow cameras online at or via INDOT’s TrafficWise app. Regular updates will also be shared on INDOT’s social media channels. Check for travel advisories in your area at
