If you were out driving Wednesday morning, chances are, you had to deal with some heavy fog.
Visibility was low Wednesday morning across Michiana.
St. Joseph County Police tell NewsCenter 16 they responded to a number of accidents, including a chain reaction crash on US 31, near Lakeville.
Three people were taken to the hospital.
The fog also forced a handful of schools to close today.
For some districts, it was the third Wednesday in a row they have canceled classes, because of the weather.
