Driving apps like Waze or Google Maps try to show you the shortest route, and apps like those often direct motorists to exit jump to save time.
Arrowood Road in south Charlotte on Interstate 77 is an example of where it happens a lot.
At the end of the exit ramp, there are clear traffic arrows telling drivers to turn left or right. Some drivers, however, go straight across the road onto the I-77 on-ramp and back onto the highway.
That is an illegal move, and drivers could get a ticket.
"Those are the ones we usually get a call about an accident later on," Pierce said. "They are the more aggressive drivers."
Exit jumping, even when it's legal, slows traffic more when impatient drivers merge back onto the road.
It also requires jumpers to make U-turns on the side roads to get back onto the interstate.
David Harvie is annoyed by people who exit jump.
“It's frustrating because they've gotta get back into traffic with you, and so trying to come in, usually they cut in. It's very aggravating," he said.
