According to a report from the Iowa State Patrol, a 60 year-old man from Ohio was eastbound on Interstate 80 near the 82 mile marker in Adair county just south west of Des Moines when he began to pass a semi-truck at about 11 AM. The semi moved from the left lane into the right lane when the motorcycle was attempting to pass the semi. The report states that the motorcyclist avoided collision with the semi and went into the median, losing control of the motorcycle, and overturned.
The motorcyclist was inured and taken to the Guthrie County Hospital by Adair County Rescue.
The “non-contact orange semi” failed to stop and continued east bound on Interstate 80 and was apparently never apprehended.
