Which of the following is a reflective delineator sign used to indicate roadworks?
Signage: Beacons and temporary signage
Explanation
Reflective delineation in roadworks: directional panels
Temporary directional panels are elements of reflective delineation used in construction areas. Their main purpose is:
- **Prohibit passage** towards the area occupied by the construction.
- **Guide the direction of safe circulation** in detours or narrowings.
- **Delimit and warn** of the presence of **construction works**, with **high reflectivity** to be visible at night or in low visibility conditions.
Thus, directional panels are used in roadworks to channel traffic and protect the construction area.
