Several years ago I was a resident of Switzerland and attempted to trade my European but non-EU driver's license for a Swiss one. To do that, I had to take a road test which I unfortunately ended up failing -- you get only one shot at it -- resulting in an automatic driving ban and a fine (they charge you about 250 francs to put a sticker that says "Not valid in Switzerland" on your license).
In the meantime I moved to Germany, which allows driver's license exchanges for people from my country without any extra hassle. Consequently, I now have a German driver's license.
My question is: I get in my car and drive to Switzerland. The police stop me for whatever reason. Am I in trouble?
