I have actually got two tips, now I am not totally sure on either one, so may want to check it out for yourself in your town.
1) in a small town, cops are not allowed to run radar, and if caught, the ticket is no good, and that can be fought.
2) when you get a ticket, there are points taken off of your license, pay that ticket with a check, write the check for $1 or 2 over what the fine is, then walk away, they have to write you a refund check, do not cash it, tear it up, if you do not cash it, the transaction is not finished, there for, they can't take the points off your license.
