Definition of 156-21

German road sign 156-21, officially designated "Bahnübergang mit dreistreifiger Bake mit Entfernungsangabe - Aufstellung links", belongs to the danger warning signs group. It warns that vulnerable road users, animals, or crossing movements may appear suddenly, so recognition and early speed reduction are essential.

Any left reference should be read as part of the direction, road side, lane arrangement, or placement shown by the sign. The practical meaning is not just the symbol itself, but the driving decision it triggers: adjust speed, position, priority, route choice, stopping behaviour, or attention before the situation becomes urgent. For learners, the key skill is anticipating what could go wrong before the hazard is visible.
