Step-by-step explanation:

All motor vehicles in Tucson and Phoenix must have had emissions tests with a model year of 2008 and newer every other year. This requirement is based on the updates made to the Federal Testing Procedure in December 2006, which were implemented with the model year 2008 vehicles.
