**Road markings** are signals painted on the roadway that guide and regulate traffic. There are different types of road markings, and it is important to know them to understand their function.

- **Transverse road marking**: This type of marking is placed perpendicular to the direction of traffic. A clear example of a transverse road marking is the **pedestrian crossing**. These are the wide lines painted on the roadway to indicate to drivers that they must stop and yield to pedestrians.


- **Longitudinal road marking**: These markings are placed in the same direction as the traffic and usually divide lanes or indicate the edge of the roadway. They are not applicable to pedestrian crossings.

- **Horizontal road marking**: This term is more general and refers to any marking painted on the road surface, without specifying its orientation.

Therefore, the **pedestrian crossing** is a **transverse road marking** because it is painted perpendicular to the flow of traffic, indicating to drivers that they must stop to allow pedestrians to cross safely.
