Do I Need an Emissions Test?

The Arizona Department of Environmental Quality is responsible for the emissions testing program and laws. For more information, contact ADEQ at 877.692.9227 or visit myazcar.com.

Emissions Test Results

Emissions test results are immediately sent electronically to MVD and you may renew your registration online

Early Registration Renewal

Early renewal is based on an emissions test requirement.

  • If an emissions 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.

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

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 at 602.771.3950 or Tucson at 520.628.5651.

Emissions Control Areas

If 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, contact the Arizona Department of Environmental Quality at 602.771.3950 or visit myazcar.com for general information and maps.
