Connecticut Truck Idling Law
Connecticut limits idling to 3 consecutive minutes (R.C.S.A. 22a-174-18, enforced by DEEP). It is waived below 20F, for heat or AC needed for the occupant's health and safety, and for auxiliary equipment like reefers, pumps, and lifts. The air statute allows fines up to $5,000 a day, but typical citations are much smaller.
