#1 rule! Always fight the ticket. You are never guilty until proven in a court of law. Nolo is the same as saying I am guilty.
Dave's rules,
It seems like a good idea, and I was going to do it once ...
I went to court and sat while the judge called person after person forward, and if they just pled guilty, he gave them "traffic school." Traffic School was an option that would expunge the ticket from your record with certainty. And it only required that you come to a one night class, taught by an old Army Vet, whose goal was to scare the bejesus out of you, pointing out that you had to be careful on the road, and that speeding was not being careful.
So I pled guilty, took the traffic school, and the ticket was erased.
The night of the traffic school, the Army Vet had a date, so we met for 10 minutes, he showed a short film, he told us that we were all going to die if we kept speeding, and he let us go after about 20 minutes. I went out and had a great steak dinner myself.
I had two other chances at Traffic School over the last 50 years. Both in a speed trap county where they were using speeding ticket donations to help with the local budget ... but traffic school tuition was just as good as a speeding ticket donation at inflating their coffers, so they would let you do traffic school instead, and the ticket would be expunged from your record.
The first of these was similar to the story above... relatively short and painless, with the focus on admonishing the wayward on the evils of speeding, except we were excused early so that we could go get free brats and beverages at a municipal celebration that was taking place that evening on the square.
The second was at Christmas time one year. They made no pretense about even telling us not to speed. We showed up, they checked us off the list, and they sent us out to the courthouse steps to join in a Christmas Carol sing.... I like Christmas, but I slipped out the back and headed for parts unknown.
