hello, a friend of mine is master of some hektar land. now I wanted to ask if it is legal to drive there with an old off-road vehicle WITHOUT Tüv and WITHOUT insurance. Tüv never gets the car again and therefore also an insurance does not bring anything. My question arises because I have heard that this private country must be fenced off, otherwise it would count as black driving. Can you please help me with this problem? TIA Jan
