In the presented situation are you allowed to turn right without stopping before the traffic lights?

On the traffic lights on the right, a red light is on together with a green arrow pointing right. This green filter arrow (signal S-2) allows you to turn right despite the red light, but under two conditions: first you must stop before the traffic lights, and then you may move off only if you do not obstruct other road users - here, for example, pedestrians on the crossing. Turning without stopping is prohibited.

The green filter arrow is a conditional signal, not an ordinary green light. The Regulation on road signs and signals says that a red signal with the arrow allows you to turn into the nearest roadway only if the driver stops before the traffic lights and does not obstruct other road users. Driving through "without stopping" at the green filter arrow is one of the most common mistakes, and you can fail the practical exam for it.
