Can you turn left at the intersection from this lane?

Why?

Your lane has a P-8a straight-ahead arrow, which permits travel straight ahead only. The sign above the lane confirms that direction, so turning left from this lane is prohibited. A green light does not permit additional directions of travel.

§ 87 ust. 1 rozporządzenia w sprawie znaków i sygnałów drogowych; znak P-8a „strzałka kierunkowa na wprost”
