The practice of “Rolling Coal” has been an ongoing issue for cyclists and pedestrians and creates not only an unhealthy environment for the cyclist or pedestrian, but creates a dangerous situation as the thick black smoke impedes the sight of the cyclist or pedestrian. With the help of testimony from members of Bike Jeffco, in 2017 a bill was passed to make coal rolling a Class A Violation. Although this practice is illegal, it still occurs occasionally. If you witness this occurring, we urge you to immediately report it by calling the Colorado State Patrol at *277.
