You are approaching a level crossing where the barriers are open. What do you do?

The combination of answers you selected is correct because approaching a level crossing where the barriers are open requires caution and preparation for possible train traffic.

1. Approaching at moderate speed ensures that you can stop safely if necessary, maintaining control of your vehicle. This aligns with the principle of ensuring safety first when it comes to railway crossings, as trains can appear unexpectedly.

2. Waiting in front of the level crossing if traffic congestion might lead you to stop on the tracks is essential. This avoids a potentially dangerous situation where your vehicle could be stranded on the tracks, increasing the risk of an accident.

According to German traffic rules, always prioritize safety around railway crossings. It's crucial to be vigilant and ready to react, even when the barriers are open, as trains can approach quickly and may not always be visible in time.
