What do these traffic signs indicate?

The traffic signs indicate a no-parking zone for all vehicles, including those using the hard shoulder. The top sign, a red circle with a crossed-out blue interior, signals that parking is prohibited entirely in that area. The accompanying sign further reinforces that vehicles are not allowed to stop or park on the marked roadway or hard shoulder.

According to German traffic regulations, these signs aim to ensure safety and prevent obstructions that could hinder traffic flow or emergency services. Therefore, both signs must be heeded to ensure compliance with the law and to maintain clear roads.
