**Orientation signs** are a type of indication signs that provide information about directions, exits, and distances on roads, highways, and expressways. These signs help drivers find their way and plan their route.

- **Location**: These signs indicate the names of towns and cities on a road or highway, as well as the distance to them. For example, signs **S-300** and **S-301** show this information on roads and highways, respectively.

- **Identification on roads**: These signs provide information about the road number, the destination it leads to, and the name of the town or city at the next exit. Signs **S-360** and **S-368** are examples of this type of signage.

**Pre-identification**, on the other hand, is not mentioned as a type of orientation sign within the indication signs. Therefore, it is not part of the categories of orientation signs as location and identification on roads are.
