Emissions Test Records and Proof in Arizona

In Arizona, vehicle emissions testing is a key component of maintaining air quality and ensuring vehicles meet state environmental standards. The Arizona Department of Environmental Quality (ADEQ) oversees the Vehicle Emissions Inspection Program (VEIP), and specific requirements apply depending on your vehicle type, location, and age.

When Emissions Testing Is Required

Emissions tests are mandatory for most vehicles registered in the Phoenix and Tucson metropolitan areas. Vehicles must typically undergo testing every one or two years, depending on the model year and weight class. Exemptions exist for newer vehicles (usually the first five years), electric vehicles, and certain collectible or military-use vehicles.

Owners are notified by the Arizona Motor Vehicle Division (MVD) when a test is due. Testing must be completed before you can renew your vehicle registration.

Accessing Emissions Test Records

Arizona’s emissions test records are automatically sent to the MVD electronically upon completion of the test at an authorized testing facility. This integration means that in most cases, vehicle owners do not need to manually submit proof of passing.

However, if a test was conducted out-of-state or if there is an issue with electronic transmission, you may need to provide proof manually. In such cases, obtain a copy of the test results from the testing facility and submit them to the MVD.

You can check your vehicle’s emissions status and test history through the MyAZCar portal, operated by ADEQ.

Providing Proof of Emissions Testing

While emissions test records are typically received automatically, you may need to provide proof in the following scenarios:

• Vehicle Sale or Transfer: Sellers must ensure the vehicle is emissions compliant if the new owner is in a testing area. Provide a copy of the passing test from within the last 90 days.
• Out-of-State Renewal: If you're renewing registration while temporarily living out-of-state, contact ADEQ for guidance on acceptable test procedures or waivers.
• MVD Request: If a record is missing or not matched, the MVD may request a printed test result or certificate.

In each case, proof should include the VIN, test date, facility ID, and results.

Failing an Emissions Test

If your vehicle fails an emissions test, repairs must be made before retesting. ADEQ offers a Voluntary Vehicle Repair Program for eligible vehicles, which can provide up to $900 in repair assistance if criteria are met.

Re-testing is free within 60 days of the initial failure. Keeping repair receipts and diagnostic documentation helps streamline this process.

Keeping Your Registration Current

Failure to comply with emissions testing requirements can result in delayed registration, penalties, or inability to legally drive your vehicle. You can confirm your registration status or update your contact information with the MVD through AZ MVD Now.
