If you are living in Germany on a perminant basis, then you would have to put in to take your driver's test again. If you are only staying for a few months then it would be best to apply for an EU license using your american one as proof of your identity and ability to drive. You would have to update or change this within 6 months of getting it. I hope this helps

I am living in Germany for over 12 months now and have not yet changed my US drivers license to a German one. Am I still legally driving here? Thanks

"As of January 1, 1999, U.S. driver's license holders must be in possession of a German license six months after entering the country, if they wish to continue driving. U.S. citizens planning to stay less than a year, however, may legally drive in Germany for up to 364 days in Germany on their U.S. driver's licenses. However, they must go to their local driver's registration office (Führerscheinstelle) prior to expiration of the six-month period after arrival and notify that office that they want to continue to drive on their U.S. license until their departure (up to 364 days, as stated above). Note that an official translation of the U.S. driver's license must be brought to the Führerscheinstelle, as well as proof that you are leaving Germany before a year has passed. Proof could be in the form of a return ticket to the U.S., a work contract with an expiration date before a year, etc. A U.S. license holder requiring a German license must contact a local German driving school which will provide information on the necessary paperwork and register the applicant for testing. Applicants do not need to take theoretical or behind-the-wheel lessons. However, driving schools recommend that applicants take one or two driving lessons in order to become acquainted with the skills to be tested. Total costs (without driving lessons) may average as much as EUR 425 for license holders from states with no reciprocal agreement with Germany. The U. S. Embassy, supported by the American Chamber of Commerce in Germany, continues to actively press all U.S. states to reach an agreement on the reciprocal recognition of driver's licenses with Germany, essentially a waiver of testing requirements. Reciprocal Agreements The German Ministry of Transport in conjunction with the German Länder has approved exemptions to the practical (road) and theoretical (written) tests for license holders from: ALABAMA ARIZONA ARKANSAS COLORADO DELAWARE IDAHO INDIANA IOWA KANSAS KENTUCKY LOUISIANA MASSACHUSETTS MICHIGAN NEW MEXICO OHIO OKLAHOMA PENNSYLVANIA SOUTH CAROLINA SOUTH DAKOTA UTAH, VIRGINIA WEST VIRGINIA WASHINGTON STATE WISCONSIN WYOMING PUERTO RICO" "Partial reciprocity agreements (exemption from the road test) have been approved for: CONNECTICUT FLORIDA ILLINOIS MINNESOTA MISSISSIPPI MISSOURI NEBRASKA NORTH CAROLINA OREGON TENNESSEE DISTRICT OF COLUMBIA" Source and further information: http://germany.usembassy.gov/acs/drivers_license.html
