On a road marked this way, are you obliged to give the right of way to the pedestrian in all circumstances?

In the photo, there is a residential street between blocks of flats; at its entrance there is sign D-52 "traffic zone" (strefa ruchu) and sign B-33, which limits speed to 30 km/h; cars are parked nearby. On this road, you are not obliged to always give way to pedestrians. The answer is: no.

The Regulation on road signs and signals states that sign D-52 marks the entrance to an internal road located in a traffic zone, and the Road Traffic Act sets out the traffic rules on public roads, in residential areas and in traffic zones - so the ordinary rules apply in a traffic zone, with no special privileges for pedestrians. Here a pedestrian has right of way only where the Act gives it to them - on a pedestrian crossing, when they step onto it, or when you are crossing a pavement; otherwise they should use the pavement. It is different in a residential area with sign D-40, where pedestrians use the whole road and always have right of way. However, you watch out for pedestrians between the blocks of flats, because on a housing estate they walk everywhere.

Legal basis: § 60c of the Regulation on road signs and signals; Art. 1 para. 1 point 1, Art. 2 point 16a, Art. 11 para. 5 and Art. 26 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
