Two people were taken by ambulance to Fremont Memorial Hospital on Wednesday evening after a car slammed into a semi-trailer on U.S. 6, triggering a second incident in which a semi-trailer overturned.
The crashes happened at about 6:15 p.m. near North County Road 232.
In the second incident, a semi-trailer went off the road and overturned while trying to avoid the initial crash scene.
The Hyundai's driver was taken by ambulance to Fremont Memorial Hospital, as was the driver of the second semi-trailer, Ohio State Highway Patrol Sgt. Angel Burgos said.
The incident began when the Hyundai rear-ended the first semi as the two vehicles were headed west on U.S. 6. The second semi, headed east, swerved to avoid the crash scene, but it ultimately overturned into a ditch, with the trailer hanging over the edge of a bridge above a nearby creek.
"He might have needed to take some kind of evasive action to avoid the car," Burgos said.
U.S. 6 remained closed at County Road 232 Wednesday evening.
The overturned semi leaked some diesel fuel at the scene, prompting an arrival from Sandusky County's hazmat team. The leak appears to be contained, Burgos said. The identities of the drivers were not immediately available.
