This is an old question that is no longer in use.
Images may be missing and the information may be dated.
You are sitting in the car from which the picture is taken and you intend to drive into lane B on the priority road. How do the right of way rules work?
It is indicated in the question that the road you are entering is a priority road. “A driver entering a priority road from another road [...] is obliged to give way to vehicles on the road they are entering.” (Swedish Road Traffic Ordinance)
The obligation to give way applies to the entire road:
“Obligation to give way [...] obliged to yield to all vehicles on the intersecting road, regardless of the direction from which they are coming.” (Du och jag i trafiken, körkortsbok / teoribok [You and me in traffic], 28th Edition, page 143).
A car in lane A may be about to overtake and is therefore crossing into lane B with two wheels. It would then be quite inappropriate for the rules to allow you to drive out onto the road.
