the german federal president's license plate is 0-1, the chancellor's 0-2, the foreign secretary's 0-3. the plate of the president of the bundestag is an exception: it shows 1-1. this is to show that the bundestag's president is not part of the government but still ranks higher in importance than the chancellor. these vehicles are tax-exempt and need not to be insured since the german government acts as insurer.
