The crash happened near an elevated stretch of expressway where the road surface can cool quickly and make driving hazardous, Tilley said.
Lisa Czarnecki said she hurried to the crash scene from her office in downtown Detroit after her husband, Ken, called to say he had been involved in the crashes. Ken was driving at about 30 miles per hour when the vehicles in front of him suddenly stopped but he wasn't able to stop too, leaving "the front of his car under that white semi," she said, pointing to the highway.
"After I identified the car to one of the (emergency) workers, I asked them to go tap on the window and ask him to wave out the door," Lisa Czarnecki said. "They managed to get him out of the vehicle and he stood up and waved."
