In this situation, do you have the right to drive behind the signalling device?

In the video you are waiting behind a motorcyclist with a passenger before a pedestrian crossing at a junction with traffic lights on a wide street in town; the traffic lights above the roadway and a second set on a post on the right show first a red signal, then red with amber, and finally green - the motorcyclist moves off. When the light is green, you are allowed to drive beyond the traffic lights. The answer is: yes.

The Regulation on road signs and signals states that a green signal given by traffic lights S-1 means permission to drive beyond the traffic lights, while a red signal and red and amber signals given at the same time mean a ban on entry - the red-and-amber phase only announces green, and you must not move off during it. The permission is not unconditional: the Road Traffic Act prohibits entering a junction if there is no room on it or beyond it to continue driving, and requires particular caution when approaching a junction and a pedestrian crossing. The motorcyclist moves off first - you let him ride away, because when moving off he may wobble or stall. You enter on green when the junction is clear, watching the crossing and vehicles that may come in from the side on red.

Legal basis: § 95 para. 1 point 1, 3 and 4 of the Regulation on road signs and signals; Art. 25 para. 1 and 4 point 1 and Art. 26 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
