The first 30 seconds on a traffic stop determines everything. The only thing you should say to a police officer who pulls you over and asks you a question is, "I don't answer questions without a lawyer." If you will invoke your right to remain silent early and often, then you won't make the mistake of giving evidence against yourself. You talking to this police officer about your day and where you've been and where you're going is a huge mistake. Not only is it important for you to say, "I don't answer questions without a lawyer."
