It is not safe to move forward into the level crossing if there is congestion just beyond it. Drivers should never enter a level crossing unless there is enough space on the other side to clear the crossing completely without stopping. Stopping on the tracks or entering when congested can be extremely dangerous as it risks the vehicle being stranded on the tracks when a train approaches, which can lead to collisions and severe consequences.

Trains always have the right of way at level crossings. Drivers must wait until the crossing is clear and ensure they can fully cross before proceeding. Entering a crossing when traffic ahead is jammed is against safety guidelines and could result in being trapped on the tracks.

Therefore, the safest action is to wait before the level crossing until the congestion beyond it clears enough to allow unimpeded passage.
