It is allowed to make a U-turn:
- Only when there is an unbroken white line.
- Correct answer: From every lane, unless it is prohibited by a specific road sign.
- Only in an intersection with traffic lights, where a left turn is permitted.
- Only in an intersection without traffic lights where a left turn is permitted.
Why this is the answer
The correct answer in the official bank: From every lane, unless it is prohibited by a specific road sign.
A U-turn is not limited to a particular type of intersection. As a general rule it is allowed unless a specific road sign prohibits it. It must be made only when safe, without obstructing or endangering other road users. An unbroken white line does not permit a U-turn; it forbids crossing it.
