What do you do when you see this traffic sign?

This traffic sign is a warning sign indicating a level crossing without barriers. The combination of responses you selected—reducing speed and being ready to brake—is crucial for safety.

When approaching such a sign, you must reduce your speed to effectively assess the situation and the presence of any trains. Additionally, being ready to brake is essential since a train could approach unexpectedly, and you need to be prepared to stop.

Observing traffic from the right only is not relevant here, as the main focus is on the risk posed by the train tracks. Following these precautions aligns with German traffic laws designed to ensure the safety of all road users.
