To overtake a **pedestrian** on **interurban roads**, it is mandatory to leave a minimum lateral separation of **1.50 meters**. This is because on these roads, which are outside towns or cities, traffic conditions are usually faster and more dangerous, requiring greater caution to ensure the safety of pedestrians.

- On **interurban roads**, drivers must be especially careful when overtaking people, animals, motorcycles, and stationary vehicles, always maintaining a distance of at least 1.50 meters.
- This safety measure is crucial to protect pedestrians walking on the shoulder, as sidewalks are not always available on these roads.

In contrast, in **urban areas** or within towns, traffic conditions are different, and the specific lateral separation regulations may vary. Therefore, the obligation to maintain a distance of 1.50 meters when overtaking pedestrians applies exclusively on interurban roads.
