Cost of Emissions Testing in Arizona
Arizona mandates emissions testing in certain areas to control air pollution and ensure vehicles meet environmental standards. If you live in the Phoenix or Tucson metro areas, you may need to get your vehicle tested regularly.
Who Needs Emissions Testing in Arizona
The Arizona Department of Environmental Quality (ADEQ) requires emissions testing for most vehicles registered in the Phoenix and Tucson metropolitan areas. Whether your vehicle needs testing depends on:
- The vehicle's age and type
- Your zip code
- How the vehicle is fueled
Most gasoline-powered vehicles that are more than five years old must be tested every one or two years. Diesel vehicles, heavy-duty vehicles, and certain hybrids have different requirements.
Check the official ADEQ Emissions Testing page to verify whether your vehicle is required to be tested based on your zip code and vehicle details.
Emissions Testing Fees in Arizona
The cost of emissions testing in Arizona depends on the type and weight of the vehicle, as well as its fuel type:
- Motorcycles and cars under 8,500 lbs (1981 and newer): $20.00
- Vehicles 1967–1980: $12.25
- Diesel vehicles (under 8,500 lbs): $20.00
- Heavy-duty vehicles (over 8,500 lbs): $25.00–$30.00 depending on test type
- OBD-II test (for newer vehicles): Typically $20.00
There are no additional fees for a retest within 60 days if your vehicle fails the initial inspection. However, repairs must be made to bring the vehicle into compliance.
Where to Get Emissions Tested
Arizona offers several state-run testing stations primarily in the Phoenix and Tucson metro areas. You can find a list of locations and current wait times using ADEQ's Find a Testing Station tool.
Testing hours and services may vary by location. Some stations accept appointments, while others operate on a first-come, first-served basis.
Payment Methods and What to Bring
Most testing stations accept:
- Credit/debit cards
- Checks
- Cash
You should bring:
- Your vehicle
- Registration renewal notice or current registration
- Payment for the fee
If your vehicle fails the test, you will receive a Vehicle Emissions Inspection Report detailing the reasons for failure. This must be presented at the time of retesting.
Emissions Waivers and Assistance Programs
If your vehicle fails the test and you've made extensive repair efforts, you may qualify for a waiver. Arizona offers waivers under certain conditions, including:
- Repair expenses exceed a set threshold
- Repairs were performed by a recognized technician
- The vehicle has failed multiple tests
Additionally, ADEQ offers a Voluntary Vehicle Repair Program (VVRP) for qualified applicants to receive financial help with emissions-related repairs.
