(UPDATE, 12:49 pm) There was one person in the vehicle; the person sustained minor injuries.
Officials are directing traffic around the scene, but have not closed the road. Traffic is reduced to one lane as they work to get the car out of the ditch.
The MHP believes the driver came out of heavy fog just as he approached a curve in the road, and the vehicle went off the road. At this point, there are no indications of excessive speed, alcohol, or drugs.
Cascade County Sheriff's deputies and Great Falls Emergency Services also responded to the crash.
