General advice in any sort of interaction with law enforcement in a traffic stop is polite, be short, consent to nothing. You don’t have to answer any questions. If the law enforcement officer starts questioning you, you can ask, “Am I detained?” If the officer says you’re not detained, say, “I don’t feel like answering any of your questions, then.” If the officer says, “I want to search your vehicle,” just say, “Thanks, but no.”
