"The rush of wind is enough to scare the life out of you," said Cpl. Ben Rugg with the Nicholasville Police Department.
It's one of the dangers of law enforcement work - traffic stops on busy roads.
Recently Nicholasville police officers have noticed an alarming trend.
"It seems like here recently anytime anybody sees an officer on the side of the road they're just not yielding the right of way," said Rugg.
He says some drivers are not changing lanes, at times putting the officer in harms way.
"We have had some close calls," said Rugg. "There have been some officers on U.S. 27, they've had a vehicle that just wasn't paying attention."
So they're putting the word out to motorists - to remember the law.
"If it's safe yield to the left - just get over one lane," said Rugg, "at the very minimum you're supposed to slow down."
Rugg has had his own close call during his time with the department - he was struck during a traffic stop.
"I felt what ended up being the right side mirror of the vehicle strike me in the back," said Rugg.
He wants to say safe, and make sure nothing happens to his fellow officers.
"The extra 30 to 40 seconds it takes to slow down and pass the emergency crew on the side of the road may save somebody else's life, and keep you out of trouble," he said.
Not yielding the right of way for emergency vehicles in Jessamine County could cost a driver around $150 in fines and court costs.
