Are you allowed to go past the traffic lights in this situation?

In the video you are driving along a street next to an estate of blocks of flats towards a pedestrian crossing with traffic lights; the traffic lights above and beside the roadway show a flashing amber signal, there is sign D-6 next to them, and people are standing on the pavement by the bus stop. You are allowed to drive beyond the traffic lights - flashing amber does not prohibit entry, it only requires particular caution. The answer is: yes.

The Regulation on road signs and signals states that a flashing amber signal shown by traffic lights warns of an existing danger or traffic disruption and requires particular caution. Traffic lights in flashing amber mode do not control traffic, so right of way is decided by signs and general rules: the Road Traffic Act requires you to reduce speed before a pedestrian crossing and give way to pedestrians who are on it or stepping onto it. You slow down, watch the people at the crossing and drive through when nobody is stepping onto the roadway.

Legal basis: § 98 para. 6 of the Regulation on road signs and signals; Art. 26 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
