A Troy man has died in a one-vehicle crash in northwestern Montana.
Sgt. Duane Bowers of the Montana Highway Patrol says 29-year-old Billy Don Norman crossed into the southbound lane of Montana Highway 56 Sunday night and crashed into a ditch.

The car rolled several times before it stopped and Norman was ejected from the vehicle.
Norman was the only person in the car and he was not wearing a seatbelt.
Authorities say the accident is under investigation but preliminary reports say he may have tried swerving around an animal or an obstruction in the roadway.
