Where:
On any road, particularly near areas where road works, lane closures, or temporary traffic diversions are in place.
These signs are often positioned before the start of the work zone to alert drivers in advance.

Purpose:
To warn drivers that road works are ahead, which may include lane closures, construction equipment, or workers on or near the road.
The advance warning helps prevent accidents and ensures the safety of both drivers and road workers.

Action:
Reduce your speed as you approach the work area.
Look out for additional warning signs indicating lane changes, speed limits, or temporary road markings.
Follow instructions from workmen or traffic controllers if present.
Be alert for obstacles, uneven surfaces, or construction equipment on the roadway.
Maintain a safe following distance from vehicles ahead, as sudden stops or slow-moving traffic are common in work zones.
Proceed cautiously until you have passed the work area and the road returns to normal conditions.
