Ordinarily the notices sent from Arizona actually state whether or not the mailing is effective as service. If the mailed notice is not service it would ordinarily say something to the extent of if you do not respond to the notice and you are personally served that you will be responsible for the costs of service. Also, in Arizona you can ordinarily attend traffic school (online schools and programs are available) and attendance at traffic school will result in the dismissal of the citation. There are some exceptions depending on the severity of the offense, but most speeding citations would allow traffic school. Traffic school would not result in a conviction or finding of responsibility, thus in Arizona no points would go against your record. Good luck.
