I have one

Other than that my record is crystal clean.
I always follow this steps when I get pulled over and few cops thanked me for doing this.
1. When you see a cop car in your rearview mirror with it's disco lights on, pull over to the side immediately.
2. Turn off the engine, pull the ebrake and turn on your hazards lights.
3. Roll down all windows down (At night turn on your interior lights)
4. Put my wallet/license with the registration on the dashboard. I also put my keys and cellphone there too.
5. If your state allows you to carry a gun and you have one in the car let him know about it.
6. Keep my hands on the wheel 9-3.
7. Answer his questions politely and keep an eye contact witht the LEO.
If you plan to argue with them and start talking about your rights then guess what? Things will go south very quickly. Remember, you can always go to court and fight for it.
Most people these days don't like the officers of the law until they need one.
