To understand why it is prohibited to change the direction of travel on road sections where overtaking is not allowed, it is important to consider road safety regulations.

- **Visibility and safety:** Changing the direction of travel in places where overtaking is prohibited usually implies that visibility is reduced or that road conditions are not safe. This may include sharp curves, changes in gradient, or adverse weather conditions such as fog or heavy rain. In these situations, limited visibility increases the risk of accidents.

- **Specific regulations:** Traffic regulations establish that the direction of travel should not be changed in places where overtaking is prohibited, unless there is a specific sign that allows it. This is because these areas are designed to minimize risks and ensure the safety of all road users.

- **Compliance with signs:** Traffic signs are essential for maintaining order and safety on the roads. All drivers must obey these signs, which are designed to indicate safe conditions for maneuvers such as changing direction.

In summary, the prohibition of changing the direction of travel on sections where overtaking is not allowed is based on the need to maintain road safety and avoid risky situations due to lack of visibility or dangerous road conditions.
