Is it permitted to make a right U-turn where the following road sign is placed?

- It is permitted, even when a “no U-turn” sign is placed.
- Yes, in daylight only.
Why this is the answer
The correct answer in the official bank: Yes, when no other sign is placed to prohibit it.
This sign requires turning right only, and a right U-turn is a turn in the same direction the arrow shows. So it is allowed, as long as no other sign prohibits U-turns at that spot. A no U-turn sign always takes priority, and the rule has nothing to do with daylight hours.
