Thankfully once I saw it was Chris Rock I knew to stop drinking that soda.
Thanks for the much needed laugh.
As to the original topic, this is what my CHL class instructor suggested with his additional comments:
1. Pull over in a safe location, off the road if possible or as far to the side.
2. Turn the engine off.
3. Hazard lights on.
4. Interior lights on if the inside of the car is dark (night or whatever).
5. Hands on the steering wheel with the window all the way down.
6. If you are armed, inform. (Ohio requires CHL holders to inform only if armed, but if it is your car they know from running the plates.)
Of course there's the polite interactions, and following all lawful requests/orders.
I think common sense is a good rule of thumb, and knowing what is required for any state you may be driving in.
My first rule of thumb, though, is if at all possible not to attract that kind of attention in the first place.
