Is it correct to place a warning triangle at a distance of 30-50 m behind the car, if the car breaks down on an express road?

In the photo, you can see an expressway with noise barriers; a white car with its bonnet raised is standing in the right lane, and a dozen or so metres behind it, on the roadway, a reflective warning triangle has been placed. A distance of 30-50 m is the requirement for ordinary roads outside a built-up area; on an expressway, the triangle must be 100 m behind the vehicle. The answer is: no.

The Road Traffic Act requires you, on a motorway or an expressway, to signal a broken-down vehicle that is stationary by switching on the hazard warning lights and placing a reflective warning triangle 100 m behind the vehicle, on the roadway or on the shoulder, depending on where the car has come to a standstill. The distance of 30-50 m applies on other roads outside a built-up area. At speeds of 120-140 km/h, a driver needs a few seconds to react and change lanes, so the triangle must warn them much earlier.

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