No-Contact Limited Emissions Test — Valid for One Year

To provide customers with an alternate choice, ADEQ can provide a No-Contact Limited Emissions Test for non-diesel vehicles, which is valid for one year, as opposed to two years with the standard On Board Diaganostic (OBD) emissions test.  To use the no-contact option, first read the following instructions and then click the pre-payment portal link at the bottom of the page. 

Pre-Payment Required: 

You will need to pre-pay the cost of this emissions test prior to arriving at the station per the following:

  • For payments made on or after 11:30 p.m., get your vehicle tested two days after today or thereafter*

Testing Fee:

  • In Phoenix,* the fee is $16
  • In Tucson,* the fee is $12.25

When You Arrive at the Station:

Step 1 - Proceed to a full-service testing lane and turn on your hazard lights.

Step 2 - Display the pre-payment confirmation email sent to you at the time you made payment, either printed out or on a mobile device, through the window to the inspector. Note: You don't need to roll down your window.

Step 3 - Follow the emissions inspector's directions to receive your No-Contact Limited Emissions Test. (This test is only valid for one year vs the standard two year OBD test.)
