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 gasoline 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.
