1) Don't violate the law. That's the overall BEST way to escape a ticket.
2) Take off any pro/anti-Obamacare stickers, pro/anti-bailout stickers or what have you. You run the risk of catching a cop's eye just because he has totally different political views.
3) Make sure your car doesn't look like you bought it from the junkyard. It tells any policeman you pass that there are probably other problems with your car, such as a broken headlight/windshield.
4) Don't do anything fancy with your vehicle. This includes decorating the outside. If it's attractive, it will also attract a cop's attention.

Also, here's how to make sure you don't get caught in the first place:
5) Always be on the lookout for a policecar. When you come across a curb or underpass, look over your shoulder. Oftentimes, police cars like to hide in those places because there they are more likely to catch speeders because people speed past them without noticing them.

6) At night, if you see a car in front of you flashing its headlights, slow down. This is "Morse code" for "Speed Device Coming Up."

I'm just sharing ideas from a book I read (and yes, I'm still not old enough to drive) from a guy named Alex Carroll, who has a book dedicated to this. Now, most of the techniques he has (all of them except these) involve lying to the officer, which I do NOT condone.
