Why this is the answer
The correct answer in the official bank: A marking of a narrow part of the road or for an obstacle.
Boards with diagonal black and white stripes are placed to mark a place where the road is narrow or has an obstacle. They do not mark a wide bridge or a road that is widening, and they are not direction posts that indicate the end of the road.
