There are few places where a person would feel as vulnerable as they would at the side of a busy highway.
However, for police officers across the Tri-State, stopping to help stranded motorists or walking up to a stopped car to issue a speeding ticket makes that vulnerability just another part of an already hazardous job.
In December 2010, Cincinnati police officer Michael Flamm stopped to help a driver involved in an accident. Seconds later, a car slid out of control and hit both men.
Flamm and the man he was helping were both taken to the hospital and have since recovered.
"I count myself very fortunate," said officer Flamm.
Lt. Bruce Hoffbauer has a similar story. He was working a crash scene 18 years ago when his patrol car was struck. Luckily, he had just gotten back inside the vehicle.
"[The car] came over and struck my patrol car and if it would have been a couple minutes later it probably would have struck me, said Lt. Hoffbauer.
In April 2012, a New Miami officer faced a similar situation. He was filling out paperwork in his cruiser when he was hit from behind.
Lt. Hoffbauer says patrolling Tri-State roadways is more dangerous today because of faster cars and more distractions for drivers and officers.
The Ohio State Highway Patrol uses crashes like the one involving rookie trooper Bent Hill, 26, late Wednesday evening to show why Ohio's "Move Over" law is so important.
Under state law, drivers must move to the left side of the road if they see a first-responder on the side of a highway. If that's not an option, drivers must slow down as they pass a scene.
The goal of the law is to help avoid crashes like the one that has trooper Hill fighting for his life.
"Our prayers and thoughts go with the family of the trooper and the state highway patrol and hopefully the officer recovers well," said Lt. Hoffbauer.
