AN ACT TO AMEND TITLE 21 OF THE DELAWARE CODE RELATING TO MOTOR VEHICLES, OPERATIONS AND EQUIPMENT, RULES OF THE ROAD, MISCELLANEOUS RULES.

This legislation creates a fine for “Coal Rolling”, a practice that is often undetectable at the time of vehicle inspection due to the ability of an operator to change functions and increase emissions after passing inspection. Coal Rolling 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. It also may include the intentional removal of the particulate filter. Practitioners often additionally modify their vehicles by installing smoke switches and smoke stacks. In addition to the environmental concern of increased emissions, there is a safety component as the excessive emissions can impair a motorist’s visibility.
