The accident occurred at about 3:30 p.m. when the car and a pickup truck that was pulling a flatbed trailer came together about a half-mile west of U.S. 68 and sent the car off the left side of the interstate, Schmutz said.
Schmutz said no one has been cited because the cause of the crash remains under investigation. Drugs and alcohol are not suspected as factors, he said.
The road was expected to be cleared by about 5 p.m.
