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

This sign indicates a bicycle zone, where bicycles have priority and motor vehicles are only allowed if they are residents or have specific access ("Anlieger frei" means "residents excepted"). In such zones, the maximum speed for any vehicle is limited to 30 km/h. This speed limit helps ensure safety for cyclists by reducing the risk of accidents and allowing a safer coexistence of bicycles and motor vehicles. When you see this sign, always drive slowly and carefully, giving priority to cyclists and respecting the 30 km/h speed limit.
