When I was in Maryland I did it all the time. There were far more than a few times that I walked away clean. I never paid the full fine or took all the points.
The best trick that I found out from a black buddy at work. Send in the card to postpone the trial as close to the last day as you can. That pushes out your court date a couple months. With a little luck you will hit a day the cop is off. If he is awake, he will postpone you back. If not it is a slam dunk, you show up and he doesn't, case dismissed. If he postpones, you postpone him back. That can ping pong a couple times or he might just let it slide once and you get dismissed. If you do end up in court 8 months later, there is a good chance you are not in the notebook the cop brought so you can ask him questions about the arrest he can't answer, Case dismissed.
OK worst case, you take the conviction. Maryland still cut it to one point and that point will not actually process through the bureaucracy for another month but by then, other points have, may have aged off. When it does post it is accrued from the date of the infraction, not the date of conviction so it ages off in 15 months instead of 24.
Those are just a few of the maryland court tricks
I moved to Florida and it is a whole different thing. The judge opened the court by saying "I see I have a bunch of traffic tickets cluttering up my docket. Be aware the maximum fine here is $1000 and I use that as a guideline. If anyone just wants to pay their ticket now, the clerk is over there". Then he called a case (fairly egregious) and threw the book at the guy.
There was a line at the clerk desk..
I saw my cop, I really didn't have a case and I got in line.
