You may be eligible to receive a reciprocal test if your vehicle is in or near an approved jurisdiction. This means vehicles registered in Connecticut may be tested in one of these jurisdictions that comply with Connecticut's testing requirements. Click here to see the list of jurisdictions.

If your vehicle is eligible to receive a comparable emissions test in one of the approved jurisdictions, you may apply for a one-time extension equivalent to the two (2) year compliance your vehicle would receive in Connecticut.

Please note: Some of these jurisdictions may NOT be able to accommodate your vehicle’s testing requirements and in some cases, emissions testing may be restricted to specific counties or regions.

For further eligibility information, please be sure to check with the applicable jurisdiction before attempting an emissions test. If you are unclear on what type of test your vehicle requires or whether the reciprocal test applies to your situation, please call the CT Emissions Program hotline at 877-469-2884 for further assistance.
