Denver, CO — A pickup truck driver’s attempt to show off by “rolling coal” backfired dramatically after he was caught speeding through a police speed trap moments later. The viral video, shared on Reddit’s r/IdiotsInCars community, shows the driver deliberately spewing thick black smoke at another vehicle before being pulled over by law enforcement just seconds later.
The incident reignited debate around the controversial and dangerous practice of “rolling coal,” where drivers modify diesel engines to emit clouds of black exhaust — often as a way to mock environmentalists, electric vehicle drivers, or cyclists.
A Dangerous and Defiant Display
In the viral clip, the driver accelerated past another car, blasting it with exhaust, only to speed directly into a radar trap. Within moments, flashing lights appeared behind him as a police cruiser initiated a stop.
The video quickly spread online, drawing thousands of views and comments from users delighted to see justice served.
“He couldn’t just pass the car normally, had to be an a** about it. True karma,” one commenter wrote.
“So satisfying,” another added. “But how dare that white car not realize this awesome truck needs the whole highway and immediately pull off?”
According to The Cool Down, the clip is the latest in a series of viral moments capturing the reckless behavior of coal rollers — drivers who intentionally modify their vehicles to spew thick black soot as a form of protest or intimidation.
The Risks of “Rolling Coal”
Experts have long warned that rolling coal poses health and safety risks to everyone on the road. The thick exhaust clouds can reduce visibility, increase crash risks, and release harmful pollutants that endanger both drivers and pedestrians.
The practice can also harm the vehicles themselves, damaging engine components and reducing fuel efficiency. In some cases, drivers have caused accidents while attempting to show off their modifications.
“Last month, another driver shared a dashcam video of a coal roller crashing into a barrier between the exit ramp and the highway while trying to spread diesel fumes across four lanes,” The Cool Down reported.
Legal Loopholes and Enforcement Challenges
While modifying a truck to roll coal is illegal under federal emissions laws, the act itself is not explicitly banned in many states. This legal gray area often forces police to rely on judgment calls when deciding whether to issue citations.
Still, as seen in this viral case, speeding violations are far easier to enforce — and frequently lead to instant consequences for reckless coal rollers.
“That was so satisfying to see,” one Redditor commented.
“Instant karma,” another wrote, summing up the sentiment shared by thousands online.
A Growing Push for Accountability
Several states, including Colorado, Maryland, and New Jersey, have proposed or passed laws to ban coal rolling specifically, citing both environmental and public safety concerns. Environmental groups have also urged the EPA to crack down on vehicle modification kits that enable this behavior.
As the viral videos continue circulating, public awareness and pressure for stricter penalties are growing — signaling that this smoke-filled form of defiance may soon be running out of road.
