In the situation that you see here, while you park a broken-down car on the road outside a built-up area, are you obliged to place a warning triangle behind it at a distance of 150 m?

In the photo, a white car with its hazard warning lights on is standing on the shoulder of a two-way road outside a built-up area, beyond a broken edge line; further on, you can see sign B-33 "50" and other vehicles. On such a road, the triangle is placed 30-50 m behind the vehicle, not 150 m - 150 m is too far, and besides, there is no such requirement in the rules. The answer is: no.

The Road Traffic Act requires you, on roads other than motorways and expressways, outside a built-up area, to signal a broken-down vehicle that is stationary by placing a reflective warning triangle 30-50 m behind the vehicle and switching on the hazard warning lights, or, if the car does not have them, the sidelights (position lights). The obligation arises when the vehicle is parked on the roadway in a place where parking is prohibited, or on the shoulder when the vehicle cannot be seen from a sufficient distance. The distance of 100 m applies only to motorways and expressways.

Legal basis: Art. 50 para. 1 point 2 letter a and para. 2 point 2 letter a of the Road Traffic Act (Prawo o ruchu drogowym)
