May a pedestrian install an information panel that provides supplemental information on a traffic sign?
Signage: Vertical signs
Explanation
**Traffic signs** are essential elements on the roads to provide information and ensure the safety of all users, both drivers and pedestrians. These signs can be of different types, such as **vertical signs** that offer information of interest or **variable message signs** that adapt to traffic conditions.
- **Only the competent authority** has the ability to install and modify these signs. This ensures that the information provided is accurate, uniform, and complies with road safety regulations.
- **Variable message signs** are an example of how information can vary according to traffic circumstances, but always under the control of the authorities. These signs are crucial for warning about dangers and giving clear instructions to drivers.

- Allowing anyone, such as a pedestrian, to install an indicative sign could lead to confusion and jeopardize road safety. Therefore, it is essential that only the authorities have this responsibility.
In summary, the installation of traffic signs is an exclusive task of the authorities to ensure that all information on the roads is clear, accurate, and safe for everyone.
