I got a speeding ticket in Texas this year (11 mph over also in a rental car) and when I paid it they told me that since I was from out of state, for an extra $80 and assuming I didn't get another ticket within 90 days, they would not send notification to AZ. No class required. That was a bargain. An attorney will either get you out of it or tell you how to minimize the damage.

What about your insurance? Can, and will, they access the record?
