I've had 9:
2 - Failure to reduce speed to avoid an accident (these are bs mandatory)
1 - Improper lane usage (wrong way on a one way street)
1 - Disobeying a traffic signal (not coming to a complete stop turning right on red)
5 - Speeding (all were the lesser offense, <25mph above the speed limit or whatever, one was about 30 over but the officer dropped it down)
That being said, I've never been given a "warning" and let off without a ticket, but I don't care, the police are doing a job.
It's a pain, but all you have to do is get a lawyer to drop the charges down to "non-moving violations" or go on court supervision and they stay off your record. I've done that for every one (paid for by myself!) and my driving record is as clean as a whistle.
