If I appealed during the 30 day period, perhaps I would have had a case, and stood a chance at getting it reversed, but you are right, my 30 days are up, and its too late.
At the time, I was not even aware of the appeal process, and that it was 30 days. I have had a handful of accidents over the last 15 years, and I was only deemed at fault on one of them before the last accident, which was about 12 years ago, and it was a fender bender, that I accepted blame for, and I did not appeal. All the other accidents other than my last accident, I was never judged at fault, so I was not even aware of an appeals process, since I never had to deal with it. I guess I know better now. Hard lesson learned.
