According to the Missouri State Highway Patrol, shortly after 10 a.m., the tractor and the tractor-trailer were both southbound on US 65 about four miles north of Princeton. The tractor, driven by 44-year-old Gilbert E. Lawson, was turning left onto a private drive. The tractor-trailer, driven by 44-year-old Timothy D. Spickard of Trenton, was attempting to pass the tractor when it hit the tractor in the northbound lane, causing Lawson to be ejected. The tractor-trailer continued on US 65, went off the east side of the road, overturning onto the driver’s side.
Lawson was transported to Wright Memorial Hospital in Trenton for treatment of serious injuries. No injuries were reported for the driver of the tractor-trailer.
