All **road users**, both **drivers** and **pedestrians**, are required to obey **traffic signals**. This is because signals are designed to regulate traffic and ensure the safety of everyone on the road.

- Traffic signals must be followed across the entire width of the street or road, and they cannot be changed without a justified cause. This ensures that all road users have the same indications and can act in a predictable and safe manner.

- At intersections, it is essential to follow the instructions of the signals to avoid accidents and facilitate the flow of traffic. For example, you should not enter an intersection if there is a risk of getting trapped and obstructing the passage of other vehicles or pedestrians.

- There are different types of signals that have priority in their obedience. First, the **signals and orders from traffic officers** must be followed. Then, temporary signals and those warning of curves and obstacles, followed by **traffic lights** and, finally, **vertical traffic signs**.


In summary, all road users must obey traffic signals to maintain safety and order on the roads.
