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

- It is permitted in an intersection with traffic lights, and prohibited in an intersection without traffic lights.
- Correct answer: Yes, unless another sign is placed to restrict this.
- It is always permitted, even when a “no U-turn” sign is placed.
- It is always forbidden.
Why this is the answer
The correct answer in the official bank: Yes, unless another sign is placed to restrict this.
The sign directs you to drive to the left, and it does not prohibit a U-turn. So a U-turn to the left is permitted where it is placed, as long as no other sign prohibits it. Such a sign takes precedence, so you cannot say the turn is permitted even when it is expressly prohibited. It also does not depend on whether the intersection has traffic lights.
