The sign "End of all route-related speed limits and overtaking bans" signifies that drivers have reached the point where all previously imposed speed limits and overtaking restrictions are no longer in effect.

According to German traffic laws, once you see this sign, you can resume normal driving speeds as defined by the general speed limits for the type of road you are on: up to 50 km/h in urban areas, 100 km/h on open roads, and up to 130 km/h on highways unless other restrictions are indicated by different signs. This sign serves as a clear indication that you can now drive faster, and you may also overtake other vehicles without any specific restrictions that were in place before this sign. Always ensure to drive safely and consider road conditions and traffic around you.
