BUTTE, Mont. (AP) — Montana highway authorities say a 66-year-old man died after losing control of his truck and crashing.

Montana Highway Patrol says the crash happened Saturday on Interstate 15 in Butte. The Montana Standard reports that the man was entering the highway when he lost control of his truck and the trailer attached behind it.

Officials believe the man overcorrected when the trailer began to fishtail, causing the trailer to slide into the median and the truck to roll over.

The man’s name has not been released. Officials said he was from Hall.

Authorities said they do not suspect alcohol, drugs or speed were factors in the crash.
