Expired license tabs. Stupid...stupid thing.
I've gotten a few speeding tickets in the past, usually in places where I was going the same pace as the rest of traffic, but happened to be at the end or easily accessible. Didn't bother contesting it since I knew I was speeding, but still thought it was annoying.
