When you have been pulled-over when operating a vehicle on public property (i.e. a highway), do you have to communicate with the officer in English in (Arizona) United States of America?
I understand that you must give them driver's license, proof of insurance, and registration, and I vaguely remember reading in the Arizona's driver's handbook that there are a set of questions you must be prepared to answer in English. However, I am not sure if this is correct.
There are generally two theories on being the best way to deal with traffic stops: 1. is to be nice and comply with the officer, nicely answering any questions; 2. is to be nice and comply only to orders they are legally obligated to follow, answering only questions they are legally obligated to answer, and speaking to the officer as minimal as possible.
But I would like to test a third theory: speaking a language the officer does not understand, and making it appear that I either barely understand the officer, or barely can speak to the officer in their language (presumably English or Spanish, most likely, in the United States).
I am thinking I will start speaking in German to the officer, and hope the officer doesn't speak German. This will frustrate the officer (and make them feel sorry for me), and make the officer want to ask as few questions as possible, without getting frustrated that I refuse to answer them. Thus, reducing the self-incriminating evidence, while reaping the benefits of not being the "I won't speak to you" jerk.
So if I spoke and listened perfectly in English, would it be obstruction of justice (or otherwise legally a lie) to intentionally construe myself as (or pretend to be) a German speaker, and not an English speaker, to the officer?
