Emissions Information

To improve air quality and reduce vehicle emissions, ADEQ administers a mandatory vehicle emissions testing and repair program known as the Vehicle Emissions Inspection Program (VEIP).

Emissions testing is required for most vehicles that are 5 years old and older, registered in the greater Phoenix and Tucson areas. Those who regularly commute into these areas for work or school are required to test their vehicles as well.

Does My Vehicle Need Emissions?

Vehicles that are model year 1967 and newer and more than 5 years old require emissions—this includes gasoline and diesel-fueled vehicles. Alternative fuel, flexible fuel (E85) and hybrid vehicles also require emissions. Newer vehicles are exempt for the first 5 years of registration. Some vehicles may require a different schedule.

  • Motorcycles, golf carts and ATVs are exempt from emissions.

  • A Classic Vehicle must have Classic Insurance at the time it is registered and throughout the duration of registration to be exempt from emissions.

Vehicles in Arizona require testing every 1 to 2 years, depending on the vehicle. If it has been over a year since your vehicle was last tested, then it may need to be retested before you can register it.

The Vehicle Emissions Control Section (VECS) created the Recognized Repair Facility (RRF) Program to reduce unready or failing emissions inspection results. RRFs are businesses that meet certain license and certification requirements. The following locations earned the RRF distinction for demonstrating considerable success in the repair of emissions-failing vehicles.
