Vehicle Emissions Testing in Arizona

In Arizona, a vehicle emissions test is required for many original registrations, as well as for annual registration renewals. Renewal notices are sent annually to vehicle owners, and indicate whether and by what date an emissions test must be completed. A Car Care programme has been initiated by the Arizona Motor Vehicle Division (MVD) in collaboration with Arizona Department of Environmental Quality (ADEQ) to keep a check on the levels of vehicle emission.


A car, truck, motor home or RV (recreational vehicle) requires an emissions test when:

  1. It is a 1968 model or newer.
  2. It is driven mainly in the Phoenix and Tuscan areas.
  3. It runs on gasoline.
  4. It runs on diesel fuel and has a manufacturer's gross vehicle weight rating 8,501 pounds or greater.


Emission tests are valid for 90 days. A valid test is required to reinstate a suspended registration and to complete an original vehicle registration or registration renewal. Used car dealers are required to issue a valid emissions test for any vehicle they sell. Getting an emissions test is the buyer's responsibility when the vehicle is purchased from a private owner.


A vehicle is exempt from emissions testing when:
  1. It is a 1966 model or older.
  2. It is either a new vehicle, or on its first or second registration.
  3. It is a hybrid-electric vehicle less than five years old.
  4. It is a motorcycle which has been registered in Tuscan city area.
  5. It is a vehicle which a dealer is transferring to another.
  6. It is a golf cart or similar small electrically operated carts.
  7. It is an alternative fuel vehicle.
  8. It is a vehicle which is registered out of state of Arizona.
  9. It is outside the areas which require a vehicle emission check. In such case you can apply for an exemption under Code 52 of the Car Care programme.


Arizona Department of Environmental Quality (ADEQ) has certain locations where you can test your vehicle. The test standards and maximum fees will be displayed at the stations.


There is a maximum emissions testing fee set by the ADEQ. The fee varies by county, type of vehicle and type of fuel. See Emissions Fees for details.


If your vehicle fails the emissions test, you must have the vehicle repaired, after which it must pass the after repairs emissions test. No inspection charge is taken the second time you bring the vehicle for emission checks after repairs within 60 days. If you are a resident of Maricopa and Pima counties you can seek financial assistance programs to get older vehicles, which are 12 years and older and fail the emissions test, duly repaired. The vehicle should also be operating on the road to be eligible for this. Contact the ADEQ Emission Test Facility in Phoenix and Tuscan to request a waiver.


  • If you are out of state, or if your vehicle is otherwise unavailable for inspection, you can register your vehicle or renew your vehicle's registration by filling in your renewal application and attach a money order or a check of $9.50 and mail it to the Arizona Department of Environmental Quality (ADEQ) with an envelope with a stamp and your address for correspondence..

Reviews of Vehicle Emissions Testing in Arizona

Is it true, seller can't transfer a title unless the vehicle is currently registered or has passed emissions? (Phoenix area)

what are the emissions laws on v8 engines swaps in s10s and is it plossibalbe to pass emissions

would a 1979 el camino need an emission test ? and if so what do they usually check for old cars like that?

Earnhardt Hyundai in Gilbert sold us a salvage title vehicle that doesn't pass emissions now that we are trying to register it.. we've already spent $180 to find out somebody had removed the check engine lights (pretty malicious), so it would never have passed emissions. Now they want $330 to 'fix' a problem they think is causing it to also fail emissions. Shouldn't they have to pay for or fix the vehicle they sold that can't pass state emissions? You'd think they wouldn't want the bad pub, but they're unscrupulous like most dealers, maybe more so because they know it is tough for 'little guys' to battle their legal dept. Any help would be appreciated!

Sometimes cars that have been stripped, damaged in an accident, or waterlogged don't get a second chance―but sometimes they do! It depends on whether the insurance company considers it financially prudent to revive the car or just send it to the junkyard. If it goes with the latter, the Motor Vehicle Division (MVD) will certify the automobile as "salvage," deeming it unfit for use on the road. It will be issued a new title branded with the term Salvage.

A vehicle sold under the salvage title is not fit for the road, so the dealer is not responsible for it failing emissions.

Sadly when you buy a used vehicle, you buy it "as is" and you should really check everything out before purchasing the vehicle. You are now responsible for the repairs and whatever it will cost to fix the problem.

Goes to show how ignorant people who run AZ can't even spell "Tucson" correctly. After suffering 57 years of my life there, I finally got out and now my kids want me to come back to that hell hole...all I can say to them is "I hate that state with the small minded Republican politicians that have moved in to ruin it." It's crowded, hot, boring, and corrupt, and I am never coming back to that rotten place. Should have left before they became the third generation in that rot gut place. I refuse to live anywhere that has an emission test for the citizen while the Military and Corporations have unrestrained polution rights. "TUCSON...NOT TUCSAN" you bunch of yo yo's.

Try moving to Detroit, a democrat run city now in bankruptcy. Only cities and states run by conservative republicans will survive. You cannot continue to pay for all the freeloaders like Tucson has done. Thats why we phoenicians always refer to it as Nogales junction. NEVER

has Tucson been run by Conservative Republicans.

And further more... They spelled it TUSCAN, NOT TUCSAN you flipping idiot. So maybe the next time you wish to prove a point, maybe make sure you spell check yourself first? Just saying. I mean since you obviously have nothing better to do than get on the MVD website to talk a bunch of political non-sense and whine about what the state is like, which has absolutely no relevance to the purpose of this site anyway... May I please suggest that you get a Facebook or Twitter account (no one has Myspace anymore) to do your mindless complaining on, so that way, people like myself who are actually on this site for something other than complaining about how crappy the state is, can do their business without this nonsense? Even though it was quite entertaining to read... Thank you for that. And also, thank you for moving. The state is better off without "yo-yo's" like you in it anyway I'm sure. Have a nice day.

where did you move to get away from all of this crazyness??I would like to stay in the u.s.

If you bothered to look at the About Us page, you'd know this web site is operated by a Canadian company. It's not even a US company.

This site isn't run by Arizona anyway.

Die, everyone, Die!!

(Full on internet rage attack)

hoo, that was fun don't live here ..but you just come to the emissions website for fun??..really nothing better to do than spell check this site..??..sounds like you might need a hobby!

First off, the republicans politicians in the state are not the one's who "moved in to run it" they are the 3rd, 4th, 5th and even 7th generation Arizonans. The democrat politicians in AZ are they ones who "moved in" from California or other backwards states who can't even keep their own houses in order, and some of our liberal legislators are anchor babies, whose parents came here illegally. THEY are the ones who are bankrupting our state and keeping us from enforcing our laws to protect the law abiding citizens.

Knew we were missing something, it was you! Couldn't cut it so you left, eh? Just one more loser gone. Maybe a 1070 issue with you. We gained by you leaving and wherever you went will now suffers by your smallness. Bye forever. Maybe you can talk your friend(s) to follow ya.

Hey...don't be so hard on those at the DMV...after all, "ENGLISH" is probably NOT their FIRST LANGUAGE!!!! I'm with you though, someone should have spell checked this is embarrassing!

It was probably spell checking that automatically changed "Tucson" to "Tuscan." As a word around the world the Italian "Tuscany" region would be better known by automatic dictionaries than our single city.

Still some local oversite of the mvd information page would have easily clarified this because everyone in Arizona and most all people in the Southwest US would spell Tucson correctly.

Tuscany according to Wikipedia has about the same land area as Pima County and has four times the population of the Tucson area. Florence, Italy in Tuscany is one of the most visited cities in the world.
