What is the maximum speed a vehicle may drive in a zone with this sign?

The sign shown indicates a bicycle zone, where only bicycles are allowed to use the road freely. The supplementary sign "Anlieger frei" means that residents or people with a valid reason (such as deliveries or property access) are also allowed to enter the zone with motor vehicles.

In a bicycle zone, the general speed limit is 30 km/h. This rule helps ensure safety for cyclists, as the area is designed to prioritize them and reduce the risk of accidents. Motor vehicles must adapt their speed accordingly and be very cautious, giving cyclists priority.

So, understanding this sign means recognizing that the maximum speed allowed is 30 km/h to protect the cyclists, while only residents or authorized vehicles may enter this zone by car. This helps you answer similar questions about speed limits in bicycle zones in Germany.
