If you have had your emissions test fail at least two times, you may qualify for a waiver.
You’ll need to demonstrate that sufficient effort and costs were incurred in an effort to repair your vehicle. See the price table here. There is a $15 fee for the waiver. Save all of your repair receipts. Once a waiver has been granted that vehicle may never receive another. Therefore, you’ll probably need to eventually get it repaired.
Waiver facilities are open 8:00 am to 4:30 pm, Monday through Friday, except for all major state holidays. There are two locations in Arizona, and they are:
600 North 40th Street
Phoenix, Arizona 85008
4040 East 29th Street
Tucson, Arizona 85711
Good luck on your vehicle inspection!
