Can you perform a U-turn manoeuvre at this intersection from the outermost right traffic lane?

In the video you are approaching a junction with traffic lights in a city in the right lane, which has a straight-on arrow painted on it, while the left lane has a left-turn arrow; the traffic lights show green. You cannot make a U-turn from the far right lane - this lane allows only going straight on, and you make a U-turn from the left lane. The answer is: no.

The Regulation on road signs and signals states that lane direction arrows mean that driving from the lane in which they are placed is allowed only in the direction shown by the arrow, and an arrow allowing a left turn in the far left lane also means permission to make a U-turn; the Road Traffic Act requires you to move towards the middle of the roadway before turning left. A U-turn from the right lane would mean crossing the path of vehicles in the left lane that are turning left or going straight on - this is one of the most dangerous situations at a junction, because the driver in the left lane does not expect a car turning in front of them from the right. You may make a U-turn only from the far left lane, unless this is prohibited by sign B-23 or directional traffic lights S-3 do not provide for this direction.

Legal basis: § 87 para. 1 and 2 of the Regulation on road signs and signals; Art. 22 para. 2 point 2 of the Road Traffic Act (Prawo o ruchu drogowym)
