I got a camera ticket in Arizona. By law they had to actually serve you within 30 days. What usually happened was you would get a nasty threatening letter telling you to sign and give up your right to that 30 day notice RFN otherwise the state WILL send a scary sheriff’s deputy TO YOUR HOME and you WILL be served IN PERSON.
I got the letter, refused to sign, never got served and later confirmed the ticket was wiped out of the system. BTW, I never heard of anyone that refused to give up their right that eventually got served.
My roommate got one a few months later and I told him what to do, but he was scared of what would happen (read what I wrote as to what exactly would happen) and he just wrote the check.
