An accident Thursday morning involving a semi and a tractor northeast of Treynor resulted in three people being injured, one of them seriously.  According to the Pottawattamie County Sheriff’s Office, 54-year old Brian Lockwood, of Oakland, was driving a 2011 Kenworth semi tractor-trailer westbound on Highway 6 at around 9:45-a.m., and was trying to pass a Kubota tractor, at about the same time the tractor was making a left-hand turn. The vehicles collided near the intersection with 330th Street.

During the collision, 51-year-old Craig Rath, of Treynor, who was driving the tractor, was ejected from the machine and landed on the roadway. The tractor was split in half and also came to rest in the roadway. Rath suffered serious injuries, and was flown from the scene to a trauma center. Lockwood, and a passenger in the semi cab, 85-year-old Ronald Lockwood, of Oakland, were treated at the scene and released.

The accident remains under investigation.
