It is prohibited to make a U-turn:
- When he drives a vehicle longer than eight meters.
- Correct answer: When the turn cannot be seen by a driver from any other direction.
- When he is in a two-way roadway.
- If a road sign prohibiting left turn is placed.
Why this is the answer
The correct answer in the official bank: When the turn cannot be seen by a driver from any other direction.
A U-turn briefly blocks the whole width of the road. So it is prohibited when the vehicle cannot be seen by drivers approaching from any direction, because they will not notice it and slow down in time. For example, on a bend, at the crest of a hill, or in poor visibility. The length of the vehicle, or driving in a two-way roadway, is not the reason for the prohibition.
