Key legal question
Whether the driveway to the Ambassadorenhof was a public road within the meaning of the road traffic rules.
Extracted holding
The area was not a public road because it served only a defined circle of users and was not open to general traffic.
Extracted reasoning
Public character depends on use by an indeterminate public, not on ownership. The signage restricting access and the purpose of the area showed it was reserved for a determinate group.
