The following traffic sign is the only sign posted at an intersection. Is it permitted to turn left?

- Yes, only during the day.
- Correct answer: No.
- Yes, only in the intersection.
- Yes, in an intersection with traffic lights.
Why this is the answer
The correct answer in the official bank: No.
A round blue sign with a white upward arrow is a mandatory sign that requires driving straight ahead only. At an intersection with no other sign allowing a turn, turning left, or right, is not allowed. The instruction applies at all hours, and the presence of traffic lights does not cancel it.
