In the last few weeks, Hilliard Police and the Ohio Highway Patrol have had four cruisers hit while on the side of the road.
They say careless, inattentive drivers are putting the lives of officers, and the public, at risk.
Hilliard Police cruiser video shows the scene alongside I-270 around 10:20 p.m. Tuesday night.
Officers had stopped and arrested an allegedly drunk driver, when an SUV clips the parked cruiser, snapping off the side-view mirror and just keeps going.
"There is no doubt in my mind they know they struck our cruiser," said Lt. Doug Lightfoot with Hilliard Police. "They just chose not to stop."
The same night in Madison County, an Ohio Highway Patrol Trooper was stopped along I-71 helping a stranded driver when a semi drove off the road and plowed into the cruiser.
"Makes your heart stop for a minute," said Lightfoot. "Someone's going to be seriously injured, or killed."
Fortunately, no one was hurt in either crash Tuesday, but he says it's only a matter of time.
And Tuesday's crash was the third crash into a Hilliard cruiser in just a few weeks.
All involved drivers who didn't change lanes while passing a cruiser on the side of the road.
"People will try to squeeze by us, when they need to just slow down completely and change lanes to get around us. If they have to stop, then stop, until you can safely change lanes and get around the officer. The law requires you to slow down and or move over. The most important thing is to slow down. because when you slow down, you increase your ability to be able to react."
With an eye toward increasing visibility and improving officer safety, Hilliard Police have started phasing in new, brighter, smarter emergency lights on their cruisers.
"But even technology doesn't replace the human brain, doesn't replace what needs to be done. We need to pay attention to what's going on around us, we need to slow down, and we need to have good reaction time."
Hilliard Police are asking for information on the driver who hit their cruiser and drove off Tuesday night.
Here's a closer look at what police describe as a dark-colored, possibly blue SUV, with damage to the passenger side, most likely the passenger mirror.
