What does this traffic sign combination indicate?

You selected the correct answer. This combination of sign and panel warns of a railway crossing ahead, and the panel with three red stripes indicates the crossing is about 240 meters away. In Germany, these stripe panels give an approximate distance: three stripes mean around 240 meters, two stripes mean 160 meters, and one stripe means 80 meters. This helps drivers gauge how far they are from the crossing and prepare to slow down if necessary. Remember this rule for future questions about railway crossing distance markers.
