Registration

Emissions

To see if your vehicle needs an emissions test, check your registration renewal notice.

The Arizona Department of Environmental Quality is responsible for the emission testing program and laws. For more information, contact the Arizona Department of Environmental Quality at the toll-free phone number, 877.692.9227, or myazcar.com.

Emissions test results are immediately sent electronically to MVD. It is not necessary to wait after completing your emissions test before renewing online or by phone.

If an emission test is not required you may renew up to six months before the expiration. If an emissions test is required, you may renew your registration up to three months before the expiration by showing your current registration at the test station.

Out-of-State Renewals

If you are temporarily out of state and require a vehicle emissions test, visit the Arizona Department of Environmental Quality website or call Phoenix 602.771.3950 or Tucson 520.628.5651.

Emissions Test Results

Emissions test results are immediately sent electronically to MVD, it is not necessary to wait after completing your emissions test before renewing online or by phone.

Emissions Test May Be Required

If the comment on the front of your registration renewal notice reads, "No Emissions Test Required", it is based on your address on file and your vehicle year. However, an emissions test may still be required if your vehicle is used to commute into an Air Quality Control area (including greater metro Phoenix and Tucson). For more information contact the Arizona Department of Environmental Quality toll free 877.692.9227 (877.myazcar) or myazcar.com.

You may also choose to have an emissions test due to warranty limitations on emissions components.

Emissions Control Areas

If the comment on the front of your registration renewal notice reads, "No Emissions Test Required," it is based on your address on file and your vehicle year. However, an emissions test may still be required if your vehicle is used to commute into an Air Quality Control area (including greater metro Phoenix and Tucson).

If you have questions about whether you reside outside the vehicle emissions control areas of metro Phoenix or Tucson, you should contact the Arizona Department of Environmental Quality at 602.771.3950 or visit myazcar.com for general information and maps.

Emissions Exempt Fee

If an Emissions Exempt fee is included in the fees listed on the front of your renewal notice, you have the option to either have an emissions test (e.g., due to warranty limitations on emissions components) or to pay the Emissions Exempt fee. This fee is collected for the Arizona Department of Environmental Quality. If you choose to have your vehicle tested, pay the required testing fee at the test station. Then, subtract from your payment the Emissions Exempt fee (not the fee paid at the test station), and enclose the emissions Compliance Certificate when you mail in your payment.
