What do these traffic signs indicate?

These traffic signs together indicate a no stopping zone on both the roadway and the hard shoulder. The blue circular sign with a red border and a red cross means no stopping at any time. The additional white plate underneath shows a car with a crossed-out image positioned on a black line that represents the roadway plus a hard shoulder.

In German traffic rules, this combination signifies that stopping or parking is prohibited not only on the main lanes but also on the hard shoulder (emergency lane). The restriction applies to the entire area covered by the sign, ensuring traffic flow and emergency access are maintained.

So, the rule to remember is that such signs prohibit stopping everywhere in the indicated area, both on the roadway and the hard shoulder. This helps avoid any misunderstandings about where stopping is allowed.
