Vertical **traffic signs** are important for indicating the end of certain restrictions or recommendations on the road. Among these signs, there is one that marks the **end of the recommended maximum speed**. This means that, upon seeing this sign, drivers can stop following the previously indicated speed recommendation.

- Signs that indicate the end of a restriction or recommendation are part of the **regulatory signs**. These signs inform about obligations, limitations, and prohibitions on the road.

- In the list of signs that end prohibitions or obligations, the **end of speed limit** sign is included. This sign allows drivers to increase their speed once they pass it.


Therefore, there is indeed a vertical sign that indicates the end of the recommended maximum speed, and it is not limited to expressways.
