AZ is the only state to inspect & test scoots for smog related items and I believe it might only be in certain counties, but I'm not positive about that, maybe some AZ scooter owner might chime in here.
As of last year or the year before, we no longer have inspections of any kind on scoots! I think we were the last state. Probably payback for the whole MLKJ fiasco. Or maybe cuz we don't do daylight savings.
