What does this traffic sign indicate?

This sign indicates the end of a 30 km/h speed zone. It means that the speed restriction of 30 km/h no longer applies beyond this point. In German traffic rules, speed limit zones are marked with clear start and end signs; the "end" sign has diagonal black stripes across the original speed limit sign. After passing this sign, you may drive according to the general speed limits or any new posted limits. Understanding these signs helps you know when specific speed restrictions begin and end.
