I've been through this twice. I got two tickets in a 3 month span. In the end, I had 0 charges on my record and nothing on me. Here's what I did.
First ticket - I got a differed deposition. It's basically like baby probation. It's not real probation, all it means is that you can't get another ticket for the probation period. (Usually 3 months) if you don't get another ticket, then all you do is pay a court cost, and the ticket gets dismissed.
Second ticket- I got it during my probation period, so naturally, I was like Oh, F**K. I'm screwed. I went and talked to the school attorney. (As a University student, I have access to a free lawyer #studentperks) She told me that all I had to do was delay the court date on the second ticket until the probation for the first ticket was up. It was pretty easy, just called and asked for a new date. The first tickets probation ends, I go to court, pay and it's done. No charges on my record, nothing. Next I go to the second ticket, and do defensive driving as an option (Since it was cheaper than another deferred deposition) Paid $25 for a 6 hour class (that only took me 1 hour XD) Turned it in, second ticket got dismissed as well.
Deferred depositions vary in cost from county to county, their typically $150-$300. If you don't mine paying, and you can stagger court dates every 3 months (which isn't that hard) than you can pretty much get as many tickets as you want, and nothing will ever go to your insurance and nothing will ever go on your record.
The moral of the story is that in the end, you can always get a ticket off your record, if you know exactly how to work the system.
