Italian driver’s license newcomer in Germany

Hello everyone, my daughter passed the B-leaving certificate about 4 weeks ago. In Italy there is a completely nonsensical law, after you can only drive a car with max 70KW and max 55kW/t in the first year after obtaining the driver’s license. This leads to the fact that most newcomers pause for a year, since there is no corresponding car in the family and then almost start again at 0. Well, we have fortunately still our Ka … My daughter is planning now, in winter in Munich There she would have the opportunity to drive with cars of relatives, but all of them do not fit into the above-mentioned scheme. Now my question, can she do so? According to my common sense yes, since she moves a dt car into D… but unfortunately – as above is evident – often have nothing to do with common sense… Can someone give you any information? Or who (which authority) could you ask in D? Thank you Greetings from South Tyrol Sascha
