Can you make a U-turn from the lane marked in this way?

In the photo, you have stopped in the far left lane before a junction with traffic lights, where an arrow allowing you to go straight on and turn left is painted; traffic lights S-1 show green, and there is no sign B-23 and no directional traffic lights S-3. You are allowed to make a U-turn here. The answer is: yes.

The Regulation on road signs and signals states that a lane direction arrow allowing a left turn, placed in the far left lane, also means permission to make a U-turn, unless this is prohibited by sign B-23 or traffic is controlled by directional traffic lights S-3. An ordinary green signal does not guarantee a conflict-free manoeuvre, so when making a U-turn you give way to oncoming vehicles, to a tram travelling on the tram tracks on the left and to pedestrians on the crossings over which you will drive.

Legal basis: § 87 para. 2 of the Regulation on road signs and signals; Art. 25 para. 1 and 2 of the Road Traffic Act (Prawo o ruchu drogowym)
