In this situation, is it permitted to stop at the right edge of the roadway?

In the video, you are entering a dual carriageway via a slip road; the one-way roadway of the slip road bends to the right between barriers, the right-hand edge is marked by a solid line, and at the end of the slip road there is sign A-7 and an acceleration lane. Stopping at the right-hand edge of the roadway is not allowed here. The answer is: no.

The Road Traffic Act states that stopping and parking a vehicle are allowed only in a place and in conditions where the vehicle is visible to other drivers from a sufficient distance and does not endanger road safety or impede traffic; it also prohibits stopping on the roadway next to a solid line marking the edge of the roadway, and on a motorway and an expressway - outside places designated for this purpose. The slip road is narrow, has one lane and runs in a curve between barriers: a car standing at its edge would be visible only from round the bend, and a driver entering behind you would have nowhere to go around it. If your car breaks down on the slip road, you switch on your hazard warning lights and, if possible, roll on to the emergency lane (hard shoulder) beyond the end of the slip road, where you place the warning triangle 100 m behind the vehicle; for any other reason you stop only at the nearest car park.
