What is the meaning of the following traffic sign?

- The sign indicates the speed limit ahead, and it applies to all vehicles.
- Correct answer: End of special speed limit.
- Special speed limit for restricted vehicles only.
- It is prohibited to drive slower (in k.p.h) than indicated in the sign.
Why this is the answer
The correct answer in the official bank: End of special speed limit.
A black diagonal stripe across a sign usually marks the end of the restriction that sign imposed. Here, the section with the special speed limit shown is over, and the normal maximum speed for that type of road and vehicle applies again. It does not allow driving at any speed, and it is not a minimum speed sign.
