pretty much all the things my dad ever told me. but i think its important to add that this is mostly for when you are brought into the station for some sort of reason.. not for a speeding ticket... if you do not talk ( and talking doesn't mean good evening officer, yes sir or no ma'am) you can and be held without being put under arrest ..
so in short.. if you are ONLY SPEEDING or pulled over for some sort of traffic violation.. you should recognize the officer that pulled you over.. you dont have to admit guilt.. just keep your hands in sight.. get your information while he/she is watching you...say hello! you can even say.. why officer.. your shirt looks extra starchy today ;-)... then when they ask if you knew that you "ran the red light" just say.. no sir i did not. when they give you the ticket.. say THANK YOOOOU! and drive away.
oh.. if it is a really rainy day.. dont say you are sorry for the officer being out in the storm. any "sorry" is an admission.. you are admitting 2 things.. one.. you might be god and causing the rain.. 2. that it was your fault for causing the officer to stop you.
oh.. and apparently in some states you can get pulled over for wearing a bikini or being shirtless. never did the shirtless thing but just letting the muscle dudes in here in on a lil secret.
