Which of the following signs means: Barrier before a level crossing?

- Correct answer: 404
- 403
- 113
- 511
Why this is the answer
The correct answer in the official bank: 404
Sign 404 is a red-and-white barrier placed before a level crossing, so it is the correct sign. When the barrier is lowered or starts to lower, stop before it and do not cross the level crossing. Sign 403 is similar in its colors, but its stripes are diagonal, and it is not the sign that means a barrier before a level crossing.
