Does the light signal displayed prohibit you from going beyond the traffic lights in this situation?

In the video you are approaching a junction with traffic lights; directional traffic lights S-3 at the left edge show a red arrow to the left, and the traffic lights above the lanes show a red light. The signal shown prohibits you from driving beyond the traffic lights. The answer is: yes.

The Regulation on road signs and signals states that the signals of directional traffic lights S-3 apply to drivers travelling in the directions shown by the arrow, and the signals have the same meaning as for traffic lights S-1: a red signal means a ban on driving beyond the traffic lights. So the red arrow to the left prohibits turning left, and the red light above the other lanes prohibits driving in the other directions. The Road Traffic Act requires you to obey light signals. You stop before the stop line or, if there is none, before the traffic lights, and wait for the green signal.

Legal basis: § 97 para. 1 and 2, § 95 para. 1 point 3 and § 99 para. 1 of the Regulation on road signs and signals; Art. 5 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
