Discontinuous line with closer strokes: warning of risk

When the spaces between the strokes of a **longitudinal discontinuous line** are **shorter than usual**, they act as a **warning signal**: indicating the **proximity of a section with special risk**.

What it means in practice:
- Indicates that a **dangerous area** is approaching (sharp curves, crests, narrowings, frequent accesses).
- May anticipate an **upcoming continuous line**, where **overtaking will be prohibited**.
- Encourages to **increase attention** and **adapt speed**.

General function and exception:
- Generally, the discontinuous line **delimits lanes** and allows lane changes and overtaking.
- With **closer strokes**, its function is reinforced as a **preventive warning** of upcoming danger.
