What does this traffic sign indicate?

This sign indicates the end of a clearway (Sonderfahrstreifen) that was reserved only for motor vehicles. A clearway is a section of road where stopping or parking is prohibited to ensure smooth traffic flow, specifically for motor vehicles. When you see this sign, it means that the special traffic rule for motor vehicles only no longer applies beyond this point. After this sign, normal parking and stopping rules resume, and the road is no longer restricted to motor vehicles only.

Understanding this helps you recognize where special driving or parking restrictions start and end, which is important to avoid fines or obstructing traffic.
