If you're pulled over for speeding just give them your licence, tell them there's no emergency and shut up. what are you going to do talk to them about the weather? If they start asking what's in your car, what have you had to drink to night, where were you tonight...(they may already be trying to peg you for the robbery down the street) then say you want your attorney.
I don't think so either. We were driving home from a concert last year, everyone in the car stoned out of their mind and probably a little drunk still from earlier in the day. Got pulled over because the car engine was smoking (out of motor oil) and we were too blitzed to even notice. The cop pulled us over and immediately started asking: Did any of you guys drink or do any drugs? Did you come back from the concert?
Option A. Would be to freak out and say: "Sorry officer, I'm going to remain silent until I speak to my lawyer." Essentially resigning to the fact that we were probably busted and then get taken to jail and processed.
Or go with option B, which is what my buddy did?
"Where did you guys come from?"
-"Coachella concert, it ended a few hours ago."
"Have you been drinking? Using drugs"
-"No officer. We drank last night but not today and we don't do drugs."
"Did you notice that your car was smoking."
-"Yeah I'm actually shocked, but it's really dark. This is an old car so it happens from time to time."
He kinda nodded and asked us if the concert was fun and then let us off telling us to get to the nearest gas station.
That kinda beats going to jail, which is exactly what would have happened if you instantly pulled the lawyer card.
