Here is a LINK to the AZ law. It says that the state needs to personally serve a violation of this nature within 90 days. And so while you do not need to pay it now, you can wait to see if you are personally served. Though being out of state, the State can seek alternative service and the court court allow it to be mailed certified with a return receipt requested. If that happens Then in addition to any fine for the ticket you also will be assessed $35 to $50 to cover service.
