Unless specifically exempted, all 1967 and newer vehicles (including diesels) that are registered in the metro Phoenix (Area A) or Tucson (Area B) emission test areas must receive an emissions inspection no more than 90 days prior to registration.

Your registration renewal application from the Motor Vehicles Division will say "Emission Test Required" when it is time to have your vehicle tested.

If you work in the emission test area, but are registered outside of the area, Arizona law requires that you have the vehicle inspected in the area to which you commute. Note: Pima County emissions tests are not valid for registration in Maricopa County.

Automobile dealers are responsible for having vehicles emissions tested prior to sale. You will be notified by Motor Vehicle Division when you need to re-register your vehicle and if it is due for emissions testing.

Vehicles to be tested must enter the inspection station under their own power. They may not be on or pulling a trailer.

Exempted Vehicles

• Model year 2004 or newer, except reconstructed, vehicles
• Model year 2006 or newer original equipment alternative fuel vehicles
• Model year 1966 and older vehicles
• Vehicles designated as "collectible" (requires collectible vehicle insurance, reported to Arizona Motor Vehicle Division by insurer)
• Electric powered, golf carts or vehicles with engine displacement of less than 90cc
• Motorcycles registered in the Tucson metropolitan area
• Apportioned vehicles (licensed in more than one state)
• Vehicles leased to a person residing outside the emission control areas
