Your vehicle’s test cycle is determined in accordance with state and federal requirements. You should receive an official notification notice (postcard) within 45 days before your vehicle’s test due date.
Your current mailing address is needed to notify you; please be sure DMV has your most current address. Check the address on your vehicle registration. If it is incorrect you must, by law, correct it. You can download the required form by clicking here or visit any DMV branch office.
If you purchase a vehicle from an authorized Connecticut dealer, the vehicle must be emissions compliant at the time of the sale. You can verify the expiration date by entering the vehicle’s Vehicle Identification Number (VIN) below.
If you purchase a vehicle from a private individual and the vehicle was previously registered in Connecticut, you will not receive a notification notice. However, it is your responsibility to have your vehicle tested within 30 days of registering it in your name, with or without a notification letter.
If you purchase a vehicle out of state, it must be emission compliant prior to you registering the vehicle unless the vehicle is exempt; click here for more information on exempted vehicles.
If you do not have the vehicle tested, it does not pass or has not been granted a waiver within the testing cycle, DMV will not renew the vehicle’s registration.
