The **work zone signage** primarily aims to **regulate traffic in the affected area**. This is crucial to ensure the safety of drivers and pedestrians when there are roadworks.

- **Vertical danger signs**: These signs, with a yellow background, inform about the rules to be followed in the work zone. They help drivers understand how they should proceed to avoid accidents.

- **Delineation signs**: These include lights, panels, and devices that highlight the works and guide drivers on the correct direction to follow. For example, a **temporary directional panel** prohibits passage in certain directions and guides where to drive.


- **Flags and cones**: These elements prohibit passage through and between them, ensuring that vehicles do not enter dangerous areas.

- **Red and yellow lights**: A fixed red light indicates that the road is closed to traffic, while yellow lights prohibit passage between them, helping to direct traffic flow safely.


In summary, work zone signage is designed to **regulate and guide traffic** safely around construction areas, avoiding confusion and accidents.
