Where:
On any road, especially near industrial areas, quarries, construction sites, mines, loading zones, or agricultural regions where heavy vehicles frequently enter, cross, or exit the roadway.

Purpose:
To warn drivers that large, slow-moving trucks or other heavy vehicles regularly cross or join the road from side roads or entrances.
These vehicles may take longer to accelerate, decelerate, or maneuver, creating potential hazards for other road users.
The sign alerts drivers to exercise caution and be prepared for possible delays or obstacles.

Action:
Reduce your speed and remain alert for trucks entering or crossing the road ahead.
Be prepared to slow down or stop, as heavy vehicles often need more time and space to complete their movements.
Maintain a safe following distance, especially behind large trucks with limited rear visibility.
Avoid overtaking near the crossing point unless you have a clear view and it is absolutely safe to do so.
Be cautious of debris, gravel, or materials that may have fallen from trucks onto the roadway.
Use headlights when visibility is poor (e.g., during dust, rain, or at dawn/dusk) so truck drivers can see you clearly.
