How To Report “Coal Rolling” Trucks

What is Rolling Coal? According to Wikipedia, rolling coal is the practice of modifying a diesel engine to increase the amount of fuel entering the engine in order to emit large amounts of black or grey sooty exhaust fumes into the air. Also may include the intentional removal of the particulate filter. Practitioners often additionally modify their vehicles by installing smoke switches and smoke stacks. Modifications to a vehicle to enable rolling coal may cost from $200 to $5,000.

Have you ever been behind a large pickup and had them rev their engines pouring smoke into the air (and your car)?

This is how you report it.

The Colorado Smoking Vehicle Hotline.

From their website:

The Smoking Vehicle Hotline program is designed to identify smoking vehicles and give owners information that will encourage them to voluntarily make needed repairs.
Report a smoking vehicle
Email the Smoking Vehicle Hotline:
  • Please include the vehicle’s license plate number and, if possible, whether it is gasoline- or diesel-powered.
  • We’ll then send a Smoking Vehicle Notification to the address that appears on the vehicle’s registration.
  • Repairs to smoking vehicles are required if a vehicle fails a mandatory emissions test because of a visible smoke problem.
    • The cause of such smoke must be corrected before the required emissions sticker can be issued.
  • A police officer may stop a smoking vehicle, issue a ticket and order the owner to make repairs.
    • Colorado law provides for a $25 fine for the first violation of the smoking vehicle law. The fine for subsequent violations is $100 (CRS 42-4-412, 413).
    • Some municipalities impose additional fines for operating a smoking vehicle.
