If you obtained your driving licence in a country that is not a member of the EU or the EEA, it loses its validity after six months. You can therefore only use your driving licence for a short-term stay in Germany.
To be allowed to drive a motor vehicle in Germany after six months, you need a German driving licence. The requirements for obtaining a German driving licence depend on the country in which your foreign driving licence was issued. For example, additional driving lessons or taking an examination may be necessary to convert the foreign driving licence into a German driving licence. Sometimes, additional documents have to be presented, such as a sight test certificate or proof of first aid skills.
You should apply for the transfer of your driving licence as soon as possible, at least three months before the deadline.
In exceptional cases, the driving licence authority may extend the deadline by up to six months on application, if you can credibly demonstrate that you will not have your normal place of residence in the Federal Republic of Germany for more than 12 months.
