Well, getting the notice that you can't renew your car registration until you get an emission's test is never fun. However, at least ADEQ makes it as seamless as possible! You pull up, grab a number and wait in your car in line until it's your turn. Once it's your turn, they have you get out of your car for a quick minute while they check the car, then you pay, you (hopefully) get approved and you're on your way! I like this location because it just a couple minutes away from the DMV so after my emissions test, I stopped by the DMV and used their automated system to renew my registration without having to wait in line. The emission's test process took no more than 10 minutes and I think it was considered a busy day. Emission's tests cost $28. Yes, even the emission's testing deserves a Yelp review!
