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

The sign indicates a bicycle zone in Germany, which means that motor vehicles must generally reduce their speed and be cautious. The top sign, marked "ZONE," signifies that this is a designated area for bicycles, while the bottom sign "Anlieger frei" indicates that access is permitted for residents or local traffic.

In such zones, while cyclists have priority, vehicles are typically subject to a maximum speed limit (often 30 km/h) to ensure the safety of all road users. Drivers should be particularly vigilant for cyclists and pedestrians, as these areas can be busier than regular streets.
