Is the conduct of the diver, who left the parked car, correct?

In the video a silver car is parked with its wheels on the pavement next to the street, and its driver's door has been left wide open towards the roadway; a yellow van passes right next to it. The driver's behaviour is not correct - the open door sticks out into the roadway and creates a danger for passing vehicles. The answer is: no.

The Road Traffic Act prohibits opening the door of a vehicle, leaving the door open or getting out without making sure that this will not create a danger to road safety or obstruct traffic, and requires you to take the precautions needed to avoid an accident while parked. A door open on the roadway side may be torn off by a passing car, and a cyclist or motorcyclist may hit it. When you get out on the roadway side, you look in the mirror and over your shoulder, open the door only for a moment and close it straight away.

Legal basis: Art. 45 para. 1 point 3 and Art. 46 para. 5 of the Road Traffic Act (Prawo o ruchu drogowym)
