I got a fix-it ticket, got the offending car thingy fixed then found a local peace officer who kindly signed my ticket. Then I put the ticket in the mail to the local court that tracks these things, thinking all was now well.
A couple of months later, I get a bill for $520 for failing to fix it and failing to appear in court to contest it. I call the court, they claim they never received my signed off ticket. I have never lost anything in the mail in my entire life, so you can imagine my suspicion already, especially since the failure of this delivery is so profitable to the recipient, who is running a steep deficit.
When I heard someone else tell me the very same story, I realized that this needs to be shared. When you turn in a fix-it ticket, it might behoove you to make a copy for your records, then carry it in and get a receipt.
