Where:
On any road approaching a railway line, especially in areas where there is limited visibility, multiple tracks, or frequent train traffic.
This sign is typically placed in advance of the crossing to give drivers sufficient warning to slow down and prepare to stop if necessary.

Purpose:
To alert drivers that they are approaching a railway crossing and that one or more train tracks intersect the road.
The sign warns of the potential danger of trains passing through and emphasizes the need for caution to prevent collisions, which can be severe due to the size and speed of trains.

Action:
Reduce your speed as you approach the railway crossing and carefully observe the area for trains or warning signals such as flashing lights, gates, or bells.
If a train is approaching, stop safely and wait for it to pass completely before proceeding.
If there is no stop line or regulatory sign, stop at least 3 meters from the nearest track, ensuring your vehicle does not block the crossing or encroach on the railway reserve.
Always check both directions for trains before crossing and proceed only when it is safe.
Be especially cautious at crossings with limited visibility, multiple tracks, or in poor weather conditions.
