Question 449 in the bank

What is the meaning of the following traffic sign?

Two upright white rectangular plates with black borders. Each plate has three diagonal red stripes, and the stripes on the two plates slant in opposite directions. Meaning: Approx. 300 meters to railway crossing.
  1. Approx. 100 meters to railway crossing.
  2. Correct answer: Approx. 300 meters to railway crossing.
  3. Approx. 30 meters to railway crossing.
  4. Approx. 150 meters to railway crossing.

Why this is the answer

The correct answer in the official bank: Approx. 300 meters to railway crossing.

The three diagonal red stripes on the white plate mark the farthest plate, about 300 meters before a railway crossing. The closer you get to the crossing, the fewer stripes the plates show, so counting the stripes tells you how much distance is left to the track.
