As far as I know the answer is Yes, however, to pass a driving test here you need to take a prescribed drivers course which is of a set number of hours, then a written test followed by a driving test.
It appears that all this can be done in English, including the written test, if you can find an instructor who understands English. Only registered instructors are allowed.
Don't worry about understanding the road sign, ( not even Bulgarians understand them
), they are pretty standard through out the EU.
My only concern is that the standard of driving here is appalling, so I would be seriously concerned about anyone driving a motorbike here.
