Trooper Jeff Boris, 28, was responding to a call of an unresponsive motorist about 7:15 p.m. and driving eastbound on state Route 82 with his lights and sirens operating, according to a release from the patrol.
A 2012 Honda traveling northbound being driven by Lauren Heeman, 21, of Avon, struck the cruiser in the intersection, the patrol said.
Boris was taken to University Hospitals Elyria Medical Center where he was treated and released. Heeman was uninjured in the crash.
Both drivers were wearing seatbelts and both vehicles were towed from the scene.
