You're riding shotgun on a traffic stop. Do you have to talk? Absolutely not. You don't have to say anything and you shouldn't say anything. But let's break that down a little bit more. Can the police officer require you to give your ID to him? Not normally. If he doesn't have reasonable, articulable suspicion of a crime, he can't even ask you for your ID. So, the bottom line is this. If you're riding shotgun during a traffic stop, if you say anything, let it be seven words. I don't answer questions without a lawyer.
