Connecticut limits motor vehicle idling to three consecutive minutes, applied citywide in Hartford by DEEP and enforced by Hartford Police on streets, school zones, and loading docks.
Under Connecticut Regulation 22a-174-18, drivers may not allow gasoline or diesel engines to idle longer than three minutes. Exceptions cover traffic, mechanical operation of equipment such as refrigeration units, emergency vehicles, and temperatures below 20 degrees Fahrenheit. Hartford emphasizes enforcement near schools and the Bushnell Park transit hub to limit child exposure to diesel exhaust. The city posts no-idling signage at municipal facilities and asks delivery fleets to comply. CT DEEP coordinates outreach with Hartford Health and Human Services to address asthma rates in north end neighborhoods.
