What to do if caught.
Firstly, not enough people who are caught fight it in court, they simply accept it, get the points and pay the fine. If more than 10% fought the ticket I think the judicial system dealing with this would be overwhelmed and brought down on its knees. If in doubt, fight it. The worst thing that can happen is that you will be convicted of you original offence. You can get a heftier fine and more points in court, but unless you were doing silly speeds, its unlikely.
Make the systems life HELL when fighting it. Remember it is going to cost the system a huge amount of money to prosecute you, in the officer's time, court's time, prosecutor's time etc. The best thing you can do is make it worse. Here are some steps you can take.
