What is the meaning of the following traffic sign?

- No overtaking for buses
- No overtaking of private vehicles.
- No overtaking for commercial vehicles.
- Correct answer: End of road section with an overtaking restriction.
Why this is the answer
The correct answer in the official bank: End of road section with an overtaking restriction.
A black diagonal stripe on a round sign marks the end of a restriction that was placed earlier. Here it marks the end of the road section with an overtaking restriction, so the overtaking restriction placed earlier ends at this spot. The other answers (no overtaking for buses, no overtaking of private vehicles, no overtaking for commercial vehicles) describe a restriction on a particular type of vehicle, whereas the sign marks the end of a restriction.
