Twelve people were taken to hospitals after a tractor-trailer went through a red light at an intersection, broadsiding a passenger van and hitting another car, the Ohio State Highway Patrol said.
The accident happened around 6 p.m. Sunday at state routes 5 and 534.
The 2010 Chevrolet van was transporting 10 Army National Guardsmen back to Camp Ravenna in Newton Falls, the patrol said.
They were taken to St. Joseph and ValleyCare Trumbull Memorial hospitals in Warren and to Robinson Memorial Hospital in Ravenna with serious injuries.
There were two people in the other car. They were taken to Robinson Memorial with nonlife-threatening injuries, the patrol reported.
The crash is under investigation and charges are pending.
The patrol said Larry Nash, the driver of the tractor-trailer, was not injured. He was hauling approximately 44,000 pounds of plastic pellets.
Alcohol is not believed to have played a role in the crash, the patrol said.
