Parkmarking, recommendation or obligation?

In fact, I trust in the V+S Hello together, I found a question and nothing in the search. Is just out of interest. With us around the area all park always totally stupid (2m apart, etc.) Now there is a place with marked parking area, for that and behind is a stop ban. In the middle is a driveway. But the parking area stops already 3m before the entrance again. This morning at the side of the exit was still half a car length parking area free. Plus just the 3m to the entrance rt. I parked there and asked the resident, who just drove out of the driveway, if that’s okay. She said that was not a problem, because after all I am not standing in front of the driveway and I don’t block the view either. Now, however, in the road is often checked, so the question, purely out of interest (yes, I will try to avoid such situations…). May I park like this? Because if not, a stop ban sign would have to be picked up there. And I’m not standing in front of the driveway either. With a caricature to understand
