In the presented situation, are you obliged to signal the fact that you have parked a broken-down car on a road which is not an express road, if the car may be seen from a sufficient distance?

In the photo, a white car with its hazard warning lights on is standing on the shoulder of a straight two-way road outside a built-up area, beyond the broken edge line; cars are coming from the opposite direction, and further on there is sign B-33 "50". The road is not an expressway, the vehicle is on the shoulder and is clearly visible from far away - in this situation the Road Traffic Act does not require you to signal that it is stationary. The answer is: no.

On roads other than motorways and expressways, the Road Traffic Act requires you to signal that a broken-down vehicle is stationary only in specific cases: outside a built-up area - when it is stationary on the roadway in a place where this is prohibited, and on the shoulder - if the vehicle is not visible from a sufficient distance. Since the car is on the shoulder and can be seen from far away, signalling is voluntary. Even so, switching on the hazard warning lights and putting out the warning triangle is a good habit - it costs nothing and increases safety, especially after dark.

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