Warning signs for level crossing with barriers and their advance warning

The **P-7 sign** indicates *danger due to the proximity of a level crossing equipped with barriers or half-barriers*. That is, it warns that the carriageway crosses a railway line and that this crossing is protected by physical elements (bars that go up and down).

The **P-9a and P-10a marker posts** indicate the **advance warning** of a:

- **Level crossing**
- **Movable bridge**
- **Quay**

These marker posts indicate that this feature is located at a **distance of 200 metres**.

In addition, these marker posts are **always accompanied** by a main warning sign, such as:

- **P-5** (level crossing without barriers)
- **P-7** (level crossing with barriers or half-barriers)
- **P-8** (level crossing with half-barriers)
- **P-27** (advance warning of a quay or similar)

Taken together, these signs warn the driver of the **existence** and **proximity** of a level crossing or other infrastructures where there may be a risk due to the crossing of trains, the movement of the roadway (movable bridge), or the presence of a dangerous edge (quay).
