What do you do when you see this traffic sign?

This traffic sign indicates a level crossing with no barriers. When you see this sign, it's important to reduce speed and be ready to brake. This is crucial because trains may be approaching, and visibility can be limited. You should also be aware of traffic coming from the right, as there may be additional vehicles or pedestrians that you need to yield to.

The combination of reducing speed and being prepared to stop ensures that you can react quickly and safely. Observing traffic from the right is necessary to navigate the intersection safely and avoid potential collisions. Following these guidelines aligns with German traffic regulations, which prioritize safety at level crossings.
