A 53-year-old man from Arizona was traveling southbound on U.S. Forest Service Road 9745 on Saturday around 3 p.m. As the man entered a right hand curve in his ATV, he lost control of the vehicle.
The driver went off the roadway to the left and overturned. Ultimately, the vehicle came to rest on top of the driver. Trapped under the ATV, the driver died of asphyxia.
Montana Highway Patrol suspects alcohol and speed to be factors in the accident. Conditions of the dirt road were reported as damp.
The name of the man has not yet been released.
