In this situation, can you use the horn?

In the video, you are turning right into an internal road on a housing estate between blocks of flats, marked at the entrance with sign D-40 "residential area" and further on with sign A-11a "speed bump"; a person in a wheelchair is moving along the right edge of the roadway in front of you. In this situation, you are not allowed to use the horn. The answer is: no.

The Road Traffic Act prohibits the use of the horn in a built-up area, unless it is necessary because of immediate danger, and it prohibits misuse of the horn. In a residential area, a pedestrian - and a person in a wheelchair is a pedestrian - uses the full width of the road and has right of way over vehicles, so this person does not create any danger here; it is you who must adapt to them. You slow down, follow them, keeping well back, or go around them in a wide arc when there is room, without honking.

Legal basis: Art. 29 para. 2 point 1 and 2, Art. 11 para. 5 and Art. 2 point 18 of the Road Traffic Act (Prawo o ruchu drogowym); § 58 para. 1 of the Regulation on road signs and signals
