What does this traffic sign indicate?

This traffic sign indicates the end of a clearway (Sonderweg) for motor vehicles only. A clearway means that parking and stopping are not allowed for motor vehicles to ensure smooth traffic flow.

When you see this sign, it means that the special rules for the clearway no longer apply past this point. Stopping or parking restrictions connected to that clearway zone are no longer in effect.

Understanding this is important because clearways improve safety and traffic flow on busy roads, so paying attention to where they begin and end helps you follow the traffic rules correctly.
