I am an Indian national and since I was working in UK as a resident, I obtained an UK driving license. After that I moved to India, that means that now I am no longer a resident of UK.

After 6 months I am planning to move to Germany. My question is can I use my UK driving license here without exchanging with German license until the validity of UK license? And if I do have to exchange, then do I have to attend theory and practical test?
