On-road heavy-duty motor vehicles with a gross vehicle weight rating of greater than 8,500 pounds may not idle for more than three consecutive minutes when the vehicle is stationary. Violators are subject to penalties of up to $500 for each offense. Heavy-duty vehicles subject to this regulation include long-haul and delivery trucks as well as transit and school buses. Emergency fire, rescue, and lifesaving vehicles are exempt. More vehicle exemptions may also apply. (Reference Delaware Administrative Code Title 7, Section 1145)
