OVERLAND PARK, KS (KCTV) - Smoke pouring out of a diesel truck is a common sight, but some truck owners are deliberately churning out the smoke.
It's called "rolling coal" and it's a kind of anti-environmentalist protest that's all over YouTube.
The protest has even caught the attention of police in Overland Park. Local law enforcement is now warning diesel drivers not to try rolling coal on their streets or they will get a ticket.
Running coal is where people who own pickup trucks with diesel engines rig them to consume more fuel so that they shoot clouds of black smoke, often at Priuses, motorcyclists, bicyclists and other things that they believe aren't burning enough fossil fuels. YouTube videos show some people rolling coal as a way to protest environmental regulations.
KCTV5 spoke to three local mechanics who will modify diesels so they can do this. They wouldn't speak on camera because they said rolling coal is not only against the law locally, but they could also get in trouble with the Environmental Protection Agency, to the tune of $25,000 for newer truck models.
Overland Park police say they will give tickets for excessive exhaust from vehicles. They haven't had any problems with it yet, but posted to their blog about it just in case drivers decide to give it a try.
The Kansas Highway Patrol said if a trooper catches someone rolling coal, it will cost them $150.
