A 41-year-old Billings man is dead after a rollover accident in Musselshell County Saturday night.

Montana Highway Patrol says the 2004 Dodge truck was headed westbound on U.S. Highway 12 between Melstone and Roundup when it drifted to the north shoulder while rounding a curve in the road.

The report says the 35-year-old male driver overcorrected, veered across the highway, hit a reflector on the south shoulder, recorrected, hit another reflector on the north shoulder, then rolled several times before coming to a rest.

The condition of the driver is unknown.

Along with the 41-year-old, the driver had two other passengers who were injured in the wreck.  A 36-year-old man is in critical condition at a Billings hospital and a 40-year-old man suffered minor injuries.

Montana Highway Patrol says it is unknown if speed or alcohol played a role in the accident.
