Grew up with 3 cops in the family. Rule 1 - always keep your hands where they can be seen...on top of the steering wheel. 2. never reach into the glove compartment to prepare your papers (insurance/proof of registration). 3. don't go diggin in your purse for your driver's license. 4. never ever make a move to get out of the car - it'll get you killed (especially in California). 5. Keep eyes straight ahead -- no eyes darting to and fro like your making sure your drugs are not in plain sight (LOL). 6. Don't start smoking a ciggie -- don't care how nervous U are. 7. don't offer up any information other than what's asked of you. Yes sir, no sir (or maam) are good answers.
Anyway, that's what I was taught
