What does a steady red light used as a barrier device on a carriageway indicate?
Signage: General rules
Explanation
The **steady red light** as a barrier device on a roadway indicates that the **road is completely closed to traffic**. This means that vehicles are not allowed to pass in that area.
- **Delineation signals**, such as the steady red light, are used to highlight works and obstacles on the road, and their main function is to close the passage to traffic.

- Unlike other signals, such as flashing red lights that temporarily prohibit passage, the steady red light indicates a complete and permanent closure of traffic at that moment.
Therefore, when you see a steady red light on the road, you must stop and not attempt to pass, as the road is closed.
