What does this traffic sign indicate?

This traffic sign indicates the end of a 30 km/h speed zone. In German traffic rules, speed limit zones are marked by signs showing the maximum permitted speed. When you see this sign with diagonal black stripes, it means that the special speed zone (in this case, 30 km/h) no longer applies from this point onward.

After passing this sign, the general speed limits for the type of road and area apply again, unless another speed limit sign appears. This sign does not indicate a minimum or recommended speed; it only signals the end of a previously set speed restriction zone.

Understanding this helps you adapt your speed correctly and ensures you follow the applicable speed limits safely and legally.
