What ends here?

This sign indicates the end of a no-waiting zone (a zone where you are not allowed to wait or park your vehicle temporarily). In German traffic rules, when you see this sign, it means the restriction on waiting ends here, and you may once again wait or park where it is otherwise allowed.

It does not end a no-stopping zone (where stopping is completely prohibited, even temporarily) nor all previous zonal prohibitions, only the no-waiting area restriction. This distinction is important because no-stopping zones have different signs and rules, involving stricter limitations.

Remember, a no-waiting zone means you cannot stop or park your vehicle except for the immediate boarding or alighting of passengers, but it's less strict than a no-stopping zone, which prohibits any stopping. This sign removes the no-waiting limitation from that point onward.
