I know this is a old post but i noticed it wasnt answered
phoenix metro area including [hoenix glendale tempe mesa chandler and countless other cities in this hell hole and the tucson metro area do have tight emission laws
there not as tight as say L.A. but being that you are moving to a city of like 4 million people or close to it you will have a culture shock
people laws everything is different
oh and I hope you like pizza ovens cause thats what summers are like
anyways I suggest you look into the arizona department of motor vehicals and check out the laws casue there are tons and tons of loopholes too
get the number and ask lots of questions but other than that youll be aight
when you get here hit me up and ill tell you the areas to stay out of and who not to talk to

BTW welcome to hell lol
