The Mack truck pulling a gravel trailer being operated by Pond, was traveling westbound on Richland County Hwy 21. Pond failed to correctly negotiate a curve on the roadway near 94th ½ Ave SE and entered the north ditch. When entering the ditch the truck/trailer rolled onto its roof. Pond sustained serious, none-life-threatening injuries from the crash and was transported by ambulance to the Sanford Hospital. Pond was cited for failing to maintain his lane of travel.
