Welcome to the Connecticut Emissions Program

There are three types of emissions waivers.

Cost Waiver
To qualify for a cost waiver, you must meet the minimum expenditure requirement on the related emissions repairs.  To qualify, the repairs must be performed by a Certified Emissions Repair Technician (CERT); click here for more information on CERTs.

Effective January 1, 2021, the minimum emissions-related repair expense required to be eligible for a cost waiver is $939.00. This figure is linked to the Consumer Price Index (CPI) and could change annually.

The minimum repair cost is for actual repairs made to the vehicle by a certified emission repair technician, after available emissions-related warranty coverage or written denial of such warranty coverage by the vehicle manufacturer. Receipts are required; estimates will not be eligible.

Economic Hardship
You must submit documentation to the DMV indicating your annual income is at or below state and federal poverty level guidelines.

You must attest that you have no other assets you could use to pay for the necessary repairs.  All information shall remain confidential.

Functional Diagnosis
Diagnostic/Functional Waiver: There must be a known reason for a vehicle’s failure, which the manufacturer has documented. In addition, the manufacturer must provide documentation, on its letterhead, indicating the known reason for why the vehicle is failing, or cannot pass an emissions test. Your vehicle will then require an inspection by DMV personnel. You may be granted this type of waiver if the DMV inspector validates that no additional repairs are required.
Note: Letters from local dealerships and repair facilities will not be accepted. The letter must be from the vehicle’s manufacturer.

If you have reviewed the waiver eligibility requirements and believe you are eligible, you may contact the DMV Emissions Division at Emissions@ct.gov or call (860)263-5611 or (860)263-5333.
