Anti-Idling Compliance and Enforcement
Connecticut regulations prohibit vehicles of all kinds from unnecessary idling for more than 3 minutes.
Regulations of Connecticut State Agencies (RCSA) 22a-174-18 applies to all vehicles in Connecticut and is enforced by DEEP field staff; however, provisions are made for weather extremes, certain service vehicles and health-related conditions.
Additionally, Public Act No. 02-56 (An Act Concerning the Idling of School Buses) gives ticketing authority to police who witness school buses idling for longer than 3 minutes.
DEEP's goal is to achieve idling reduction through voluntary compliance. However, violations are subject to enforcement action.
DEEP's Air Management field staff work to ensure compliance with Connecticut's idling restriction by monitoring vehicle behavior at rest areas, schools, truck stops and at commercial delivery points, and pursuing enforcement when idling violations are observed.
Field staff also respond to complaints of idling vehicles, when citizens report noncompliance with RCSA 22a-174-18, to DEEP's complaint line.
Please call DEEP's Air Quality Complaint Line to report idling: (860) 424-3436
DEEP continues to target excessive idling of motor vehicles with an ongoing enforcement initiative. An increased field inspection presence in locations where excessive idling is likely to occur has resulted in the issuance of numerous Notices of Violation.
In August 2008, a Consent Order was issued to a busing transportation company operating in Windsor Locks, which had repeated documented occurrences of excessive idling. The Order required the company to develop and implement an Anti-Idling Education and Training program for its staff and included a financial penalty.
Connecticut anti-idling regulations are federally enforceable and the Environmental Protection Agency (EPA) has initiated several enforcement actions (2009 & 2012 EPA News Release Archive) against companies that violate state idling laws.
EPA has also established the SmartWay program. The SmartWay program is a voluntary collaboration that EPA and the freight industry designed to increase energy efficiency while significantly reducing greenhouse gases and air pollution.
