Black ice resulted in several motor vehicle accidents this morning. About 6:30 a.m., Emergency Responders were called to a rollover on U.S 20 near Rolling Prairie. At least two people were said to be inside vehicles near 200 East. 

Police say, they had asked for street crews to apply salt on a stretch of Roeske Ave. in Michigan City,  described as a "sheet of ice for" about an hour.  There was a mist in the air freezing on the pavement with temperatures just below freezing at the time.
