What is required if an owner of a five-year registered vehicle relocates from an non-emissions testing area to an emissions-testing required area?

The vehicle would no longer be eligible for a five-year registration if it does not meet any of the criteria listed in question above. The vehicle owner would now be subject to emissions testing requirements and will have to register the vehicle in their new area.

Can a vehicle be purchased in an area where it would require emissions testing and be registered for five years in an area where emissions testing is not required?

Yes. Generally, the determining factor for a five-year registration is where the vehicle is registered and not where it is purchased. However, a vehicle that is used for commuting into an area where an emissions test is required must be emissions tested no matter where it is registered.

What types of vehicles are eligible for five-year registration?

Any vehicles not subject to emissions testing requirement for the entire five-year registration cycle, which include the following:

  • Most vehicles registered outside the Phoenix and Tucson metro areas
  • Vehicles with model year 1966 and older
  • New vehicles that have never been registered in Arizona or in any other state
  • Motorcycles 
  • Commercially registered trailers 10,000 lbs GVW and less
  • Solar, electric and hydrogen powered alternative fuel vehicles
