I am moving to Germany in a month. I have a Mass. DL now. What will I have to do in Germany to drive? Thanks. Each German state has it's own rules for each US state. Check the government web site below to find the rules. If you have to take a written test, don't worry. It can be done in English.
Also, before you leave the US, I recommend that you go to your local DMV and request a replacement DL. Tell them you lost your license and need a new one. In Germany they'll take your US license and never give it back.
