The "End of the highway" sign (zeichen 390) indicates the end of the highway or motorway. This means that after this point, the road you are driving on is no longer classified as a highway. You should be prepared for changes in road conditions, speed limits, and traffic regulations. Generally, once you pass this sign, the following rules apply:

1. The speed limits may change from the highway regulations, which typically allow higher speeds.
2. There may be upcoming intersections, traffic signals, or pedestrian crossings.
3. Be aware of more entrances and exits, as the road will likely connect to local roads or streets.

Drivers should remain attentive and adjust their driving behavior accordingly after passing this sign. If you have additional questions about driving rules or specifics about what to expect after this sign, feel free to ask!
