When approaching an intersection regulated by this warning sign, which priority rule must you apply?

Question

DentroTest · Accepted Answer

Sign P-1b warns of danger due to the proximity of an intersection with a side road on the left, whose users must yield. Therefore, anyone traveling on the signed main road keeps the right of way over vehicles that enter or approach from that left side. Being required to stop, or to yield even if only by slowing down, to the vehicles on the left wrongly attributes the duty to yield to those traveling on the priority roadway: those who must yield are the ones on the side road.
