Where:
On any road, especially in urban areas, near intersections, toll plazas, construction zones, or areas with high traffic volumes.
This sign is placed where traffic may slow down or stop unexpectedly due to congestion ahead.

Purpose:
To warn drivers that there is a possibility of heavy traffic or traffic jams ahead.
Congestion increases the risk of rear-end collisions, sudden braking, and other traffic hazards, so advance warning helps drivers prepare and reduce risk.

Action:
Reduce your speed and be prepared for sudden stops or slow-moving traffic.
Maintain a safe following distance from the vehicle in front to allow enough reaction time.
Stay alert for lane changes, merging vehicles, or vehicles entering and exiting the road.
Be patient and avoid aggressive driving, such as overtaking unnecessarily, as this can increase the risk of accidents.
Use signals early when changing lanes or turning to alert other drivers of your intentions.
