The Billings Gazette reports that a man was sent to the hospital after a two-vehicle crash Wednesday night.  The wreck reportedly occurred when a man ran a stop sign heading south on 12th Avenue South, colliding with a westbound vehicle on State Avenue.  The crash caused one of the vehicles to land on its roof, sending its driver to the hospital with injuries that were not considered life-threatening, according to Billings Police. Sgt. Matt Lennick said alcohol may be a factor in the crash.
