Why this is the answer
The correct answer in the official bank: From all lanes, unless prohibited by a road sign.
A U-turn is permitted from any lane, unless a road sign prohibits it. It is not limited to a junction with traffic lights or to a junction without them. It must be done safely, without endangering or obstructing traffic, so you must make sure the road is clear.
