Frosty roads were to blame for an accident that sent this vehicle skidding across the median on Interstate 90 Tuesday morning just west of Luverne. The driver of the car, Sarah Smook, and her mother, Arlene Smook, both of Luverne, were on their way to Sioux Falls at about 9 a.m. in the west-bound lane when the tires started skidding. They ended up upside down in the eastbound lane before the vehicle came to a stop. The two were taken by ambulance to Luverne Community Hospital where Arlene was treated for torn shoulder ligaments and was released. Sarah suffered a broken toe and possible whiplash. She was held overnight for observation. Both occupants were wearing their seatbelts. "I’m sure that made a big difference," Arlene said from her daughter’s hospital room Tuesday. "I’m very grateful … we’re doing OK."
