HELENA, Mont. -

A 57-year-old Helena man has died in a one-vehicle rollover on U.S. Highway 12 east of East Helena.
    
The Montana Highway Patrol reports the man was westbound just before 9:30 p.m. Sunday when his car went off the right side of the road. The patrol says the driver appeared to overcorrect, causing the car to rotate counter-clockwise. The car then rolled and the driver was ejected.
    
Broadwater County authorities say David Rapstad died at the scene.
