I suggest that you call the court clerk for the jurisdiction and simply ask informally what you can expect based on how the judge normally handles similar situations.
Uhm, yeah, I took that advice once. Didn't work out well at all.
I called because the cop who wrote the ticket said anything over 15 over was a mandatory court appearance... (FWIW I was going 52 in a 35 on a back country road I've driven for 10 years and never under 50. That's just how traffic rolls there, so this was a new revenue opportunity for them).
I called the clerk, she said, well, yeah, you're supposed to come in, but if you want to pay it out it will be $135.00. She then went on to say, since this is your first ticket in our jurisdiction, if you do come in, you'll likely get a lesser fine. I can't quote you for sure, but the judge generally goes easy on first timers, so I'd think you'd be looking around $50 plus court costs and maybe no points, sometime he does that. In other words, worth it to show up.
So I took 1/2 a day off work, showed up dressed appropriately and waited my turn.
One of the guys in front of me took is 50,000 LB 18 wheeler over a bridge rated for 4 tons, and the judge reduced him to an equipment violation as to not affect is Commercial License Status.
So I *thought*, hell yeah this will be good.
Not so, I plead no contest, agreeing to the facts but not admitting guilt.
Blam $150 fine ($15 more than if I'd paid it out), plus $35 in court costs. = $185 and still got the points. Yipppeeee....
If you're really worried about the points, get a lawyer. They seem to know how to get things reduced, but then the cost ya something. There is no free lunch, points or $$...
Since you were not 20 over 84-65 = 19... Isn't that just 2 points? Or are those 2 points critical to you at this moment in time?
