Which prohibitions cease to apply when you see this sign?

The sign you provided indicates the end of prohibitions, specifically related to no overtaking and speed restrictions. According to German traffic regulations, when you see this sign, it means that the previous restrictions (such as no overtaking and specified speed limits) no longer apply.

It's important to understand that speed limits reinstated by other signs further along the road may still need to be observed. The cessation of these prohibitions allows for more flexible driving, but drivers should remain attentive to their surroundings and any new traffic signs that may indicate changes again. The prohibition against parking, however, is not affected by this sign and would still need to be considered based on other regulations or signs present.
