Is switching on the emergency lights and placing a warning triangle at the distance of 50-70 m behind the vehicle the right way to indicate that it has broken-down on a motorway?

In the video you are driving on a motorway along noise barriers and passing a reflective warning triangle placed on the emergency lane (hard shoulder), beyond which, in the distance, a person is standing on the emergency lane next to a stationary vehicle. Switching on the hazard warning lights and placing the triangle 50-70 m behind the vehicle is not the correct way to signal a breakdown on a motorway - the triangle must be placed 100 m behind the car. The answer is: no.

The Road Traffic Act requires you to signal that a vehicle has stopped because of a breakdown or an accident on a motorway or expressway, in every case, by switching on the hazard warning lights (and, if the vehicle does not have them, the sidelights) and by placing a reflective warning triangle 100 m behind the vehicle, on the roadway or on the shoulder, depending on where the vehicle has come to a standstill. The distance of 30-50 m applies on ordinary roads outside built-up areas. At 140 km/h a car covers 70 m in less than 2 seconds, which is why the triangle must warn from a greater distance.
