Next steps after a failed Connecticut emissions test

If your vehicle failed its emissions test, that means it is exceeding the allowable emissions standards for the year in which it was manufactured. It should be diagnosed by a professional automotive repair technician to determine the underlying reason(s) for the failure, and to identify the repairs necessary to correct the problem(s). You must have it repaired and retested within 60 calendar days from the date of the initial test. You may always have your vehicle repaired at a facility of your choice, or you may make the repairs yourself. However, the State of Connecticut Department of Motor Vehicles (DMV) highly recommends that you have the repairs performed at a Certified Emissions Repair Facility (CERF), as these facilities employ Certified Emissions Repair Technicians (CERTs), who are trained and certified in emissions-related failures and repairs.

If your vehicle fails a second test, you may qualify for a cost waiver, provided the repairs are performed at a Certified Emissions Repair Facility and certain cost criteria are met.

Depending on the age and mileage of your vehicle, certain emissions components are eligible for a federally mandated manufacturer's warranty in the event of a failed emissions test that was the result of a manufacturer defect. This coverage may extend up to eight years or 80,000 miles.
