Hey Viktoriya,
If you have a valid driving licence, you are permitted in Germany to drive vehicles of the class for which your driving licence is issued. If you have an international driving licence, there is no need to carry a translation with you; if you have a national, Ukrainian driving licence, you need a translation of it. Caution! Your driving licence is valid only for the first six months when you register an apartment in Germany.
Essentially, on expiry of the 6-month period, a driving licence issued in Germany is required. In general, in the case of a driving licence obtained in Ukraine, transfer of your foreign driving licence is conditional upon you passing the theoretical and practical driving test. From the driving licence authority responsible in the place where you live, you can find out which other supporting documents may be required for the application.
Have fun and drive carefully ! I wish you all the best.
