CHICAGO -- High winds with slushy wet snow turning to ice made the interstate dangerous in Northwest Indiana.
Aaron Allington, a driver out of Traverse City, Michigan, has seen wintry conditions before. He says if you absolutely have to drive extra spacing between vehicles is critical.
The dangerous conditions are why Indiana State Police are urging motorists to avoid Northwest Indiana until the weather blows over.
Many truckers who spoke to WGN said they are heeding that advice and staying put at truck stops overnight.
Emergency crews had trouble keeping up with the weather, and a State of Emergency was put in place for Porter County.
About 300 schools in the region were closed.
