Are you allowed in this place to turn right from the lane you are taking?

Why?

No, you can no longer take the right-hand branch from your current lane. A solid line and a hatched area marked P-21 separate it from your lane, and you must not enter that area. You needed to move into the correct lane before this marking began.

§ 90 ust. 5 rozporządzenia w sprawie znaków i sygnałów drogowych, znak P-21 „powierzchnia wyłączona”
