Talked with k9groomer8157 last night and he told me that 3 weeks ago Arizona reopened its HOV Clean Air plate program back up to the public. He had just gotten his new plate at that time through the program but wasn't sure how long they would keep it open. If you own a Prius, Inisght or HCH you can get a special clean air plate that allows you to drive in the car pool lane.
I immediately jumped on the DMV website but to my dismay they had once again closed the program to new plate holders....... BUT! IF.... you already had the Clean Air plate from the original program intro 5-6 years ago it is now transferable to a different vehicle as long as it was one of the 3 mentioned above. I had this plate on my Prius until it was totaled last year. At the time it was considered "NON-TRANSFERABLE" and I got stuck with a normal AZ plate on my Insight replacement.
So, today went to DMV and got my old Prius plate transfered no issue to my G1 Insight. I can now once again drive in the car pool lane!!!
If you have the plate but had trouble transfering to your new car they changed the rules.
