I used to just pay up, first few. Got insurance hikes, then finally started to get it after hitting an obvious speed trap, 4 lane wide open highway with 25 MPH limit, everybody was waived to stop and given a ticket 6 cars at a time. That's the one in PA, where I took it to court, having my friend as witness, the judge did not even give me or my friend chance to speak, officer was not there, no prosecutor either, found me guilty 29 in 25
So, I would only count after that. 2 dismissed with lawyer, 2 on my own, 1 guilty (only because I could not come back from MA to NJ, and chose that instead of rescheduling the trial, cop was not there), 1 still in appeal.
Every one of those a speed trap (ha, making excuses, sure). So, all in all 4 to 2 if you count the one appealed as lost. This happened over the course of 12 years, never mind calling me irresponsible driver. Of course, no guarantees you win, but at least you have a fair shot if you know what you do.
