If it's just a routine traffic stop, are the police allowed to ask personal questions? So, here's Dr. Judge's opinion on that. Any question by a police officer is a personal question. The first question they're going to ask you when they walk up to your window is, "Where are you coming from? Where are you going to? Are you taking any medication? Have you had anything to drink today?" Those are all personal questions that are none of his business. Play it safe. Answer the same thing every time. I don't answer questions without a lawyer.
