Are you allowed at this intersection to make a U-turn from the traffic lane you are in?

You are driving in the far left lane, which has a lane direction arrow painted on it allowing a left turn and going straight on. The junction is marked with sign D-1 "priority road", and there is no sign B-23 "no U-turns" and no directional traffic lights. In these conditions, the left-turn arrow in the far left lane also allows you to make a U-turn.

The Regulation on road signs and signals says that a lane direction arrow allowing a left turn, painted 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. When making a U-turn, you signal the manoeuvre with the left indicator, give way to oncoming vehicles and to pedestrians, and make sure that you will not endanger safety.

Legal basis: § 87 para. 2 of the Regulation on road signs and signals; Art. 22 para. 5 and para. 6 point 4 of the Road Traffic Act (Prawo o ruchu drogowym)
