A Warsaw man suffered serious injuries after his truck left a Benton County roadway Friday night.

The Missouri State Highway Patrol responded to the one-vehicle crash before 10 p.m. along Route MM just south of Johnson Drive, about six miles east of Warsaw. According to the patrol, the truck was heading east on the highway when it ran off the roadway, striking a road sign followed by a utility pole. The driver was flown to a Columbia hospital. Troopers say he was not wearing his seat belt at the time of the crash.
