These signs are used for temporary traffic arrangements to ensure a safe and clearly organized traffic environment during roadworks, construction activities, and other work taking place in or near road areas.

The purpose of the signs is to inform, warn, and guide road users through or around a work zone. By correctly placing traffic signs and barriers, traffic can be directed safely while allowing work to be carried out without unnecessary risks.

The signs can be used to:
- Warn about ongoing work
- Display temporary speed limits
- Guide traffic around obstacles or closed areas
- Inform about restricted access or limited road space
- Prevent unauthorized traffic within the work zone

Properly placed signs help create a clear traffic environment, reduce the risk of accidents, and improve safety for both road users and workers in the area.
