What do you have to be aware of when you see this traffic sign combination?

This traffic sign combination consists of a warning sign indicating a railway crossing ahead, along with a distance marker below it. In German traffic rules:

1. The triangular sign with the train symbol warns you of a railway crossing ahead.
2. The white rectangular plate with three red slashes shows the remaining distance to the crossing, with each slash representing 80 meters. Three slashes mean the crossing is 240 meters away.
3. If there is an additional sign prohibiting overtaking (not shown here but mentioned as correct in your quiz), it means you are not allowed to overtake other vehicles before reaching the railway crossing.

Together, these signs instruct you to be cautious because a railway crossing is coming up in 240 meters and that overtaking is prohibited in this area to increase safety. Understanding these distance markers and overtaking restrictions is essential to prepare for stopping if a train approaches and to avoid accidents near railway crossings.
