Does this road marking allow you to make a U-turn?

In the video you are driving along a wide street in town and approaching a junction; in the far left lane a lane direction arrow for turning left is painted, and next to the roadway, on a traffic island, there is sign C-9 "keep right of the sign". This road marking allows you to make a U-turn. 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 vertical sign B-23 or traffic is controlled by directional traffic lights S-3. In the video there is no sign B-23 and no directional traffic lights, so from this lane you can either turn left or make a U-turn. When making a U-turn, you give way to oncoming vehicles going straight on and turning right, and you check whether your turning radius lets you fit within the side roadway.

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