Where I live, and maybe elsewhere in the USA, they have this rule that you can get a speeding ticket dismissed if you take a 'defensive driving' course. Its about an 8 hour course you can take in a classroom or even online now. You're supposed to be able to get rid of 1 ticket every two years this way. Any more tickets than this and you just have to deal with it, e.g., usually pay a fine.
But, I found out that they don't really have a way to check and see if you've already had your 1 ticket (per two years) dismissed or not. This is especially true if you get your tickets in two different counties or towns.
In other words, every time you get a ticket, you can just keep telling them you want to take defensive driving, and they just keep dismissing the new tickets you get.
So, theoretically, you could get dozens of tickets and your record could stay clean. However, I think its probably better if you use this technique only at most once or twice a year.
