The **road signage** has the main objective of **warning, informing, ordering, or regulating** the behavior of road users. This is achieved through different types of signs that fulfill specific functions:

- **Delineation signs**: These signs, such as provisional directional panels and lights, indicate the direction to follow and warn about obstacles on the road. For example, a **steady red light** indicates that the road is closed to traffic, while **permanent directional panels** warn about the level of danger in an area.


- **Vertical indication signs**: These signs provide information of interest to both drivers and pedestrians, helping to make informed decisions on the road.

- **Panels with changing messages**: These panels adapt to traffic circumstances to offer updated information, danger warnings, and recommendations that should be followed.


In summary, signage is essential to **warn about dangers**, **inform about road conditions**, and **order the flow of traffic**, thus ensuring safety and efficiency on the roads.
