I wouldn't answer any question other than "Is this address on your license current?" Assuming he tells you immediately why he pulled you over, any question related to that is an attempt to get you to confess. Any question unrelated to that is a fishing expedition. You can't help yourself by helping him with either.

If he pulled me over for speeding, any question unrelated to that I'd answer with, "What does that have to do with the reason for this stop?" or "Officer, everything you need to know is on the documents I just handed you. Am I free to go or are you detaining me?"

Never give a yes or no. Ask him the questions. Let him know you're not going to talk your way into a search or an arrest. If you can't think of anything else, just say, "I don't have to answer any questions and am not going to. Am I free to go or are you detaining me?"
