Welcome to the Connecticut Emissions Program

DMV’s policy, in accordance with Connecticut Law (C.G.S. 14-164c) is to assign emissions eligible vehicles a biennial recurring due date. When a vehicle passes its required biennial inspection, providing it was tested by its scheduled due date, its next scheduled emission due date will be two years from its previous due date.

Unfortunately, a number of vehicles are late for their scheduled emission inspection dates. Vehicles that are tested more than 30 days past their initial due date or more than 60 days past their retest due date, will be assigned a future test date which reflects either the balance of the every two year test cycle or a minimum of one year, whichever is greater.
