According to Trooper Scott Moore of the Ohio State Highway Patrol, the crash involved four people total.

Moore said the wreck happened after one of the three drivers involved made an improper lane change, trying to avoid a flare in the road set-up to warn motorists of a low-hanging tree branch.

"One of the motorists made an improper lane change basically cutting off another southbound vehicle, and that's what caused the chain of events," Trooper Scott Moore said.

NEWS9 talked with eyewitness Nicole Lucas, who said: "I saw the car smash into the other car and it hit the guardrail, and that was all that I saw. And then the car in front of me slammed on their brakes, I hit mine and we've been sitting here dead stopped ever since."

Southbound traffic on 7 lined the roadway for about three miles and didn't move for more than an hour while emergency crews cleaned up the wreckage.

The Ohio Department of Transportation made it out to the scene to cut down the tree that was hanging low, so that a flare would no longer have to sit on the roadway.

The driver accused of making an improper lane change is being cited by OSHP.

Troopers told NEWS9 neither of the two people transported to a hospital face life-threatening injuries.
