Kamler said his drivers face close calls often, including one just this week where one of his employees was nearly hit by a passing car.
He says it can be scary for tow truck operators.
"I'm very scared," he said. "It shouldn't be happening."
Missouri law requires drivers to move over to an inside lane and slow down when approaching emergency vehicles. This includes tow trucks.
"It's inherently dangerous to be in those types of locations and that is why this law was passed," Sgt. Sheldon Lyon with the Missouri State Highway Patrol said.
Lyon said troopers have to work on the side of the road almost daily.
"We lose more troopers to being struck when they're outside of their vehicle than any other reason," Lyon said.
According to the International Towing and Recovery Association, between 50 and 100 tow drivers are killed each year by passing motorists.
Kamler knew a tow driver killed in Kansas City last year. By getting this message out, he is hoping to prevent it from happening to one of his own.
"We're not that easy to see if we just pull up in front of a vehicle and park," Kamler said.
He plans to install red lights on all of his assist trucks to replace the yellow ones he currently uses. Kamler said he hopes this will get drivers to pay better attention.
The Highway Patrol wants to remind drivers to be attentive when driving as well.
