Officially, the Arizona Department of Transportation does not administer vehicle emissions tests – those are performed and governed by the Arizona Department of Environmental Quality.
But because vehicle emissions tests can be required to register and renew registration with the Motor Vehicle Division
, we thought it’d be a good idea to pass along some tips to make your next trip to an emissions testing station a quick one.
First, know if you need a vehicle emissions test to renew your registration. This information will be on the renewal notice.
Next, find the nearest station
and pick a time when stations have the fewest customers. Typically, wait times are shortest during the middle of the month; middle of the week and after 5 p.m. on weekdays; and Saturday afternoons. Can’t plan that far ahead? No problem, ADEQ provides up-to-the-minute wait times for its stations here
, indicating if waits are less than 10 minutes, between 11 to 20 minutes and more than 20 minutes.
