In this situation, are you approaching a crossroads, where the right of way is determined by road signs?

The warning sign A-5 'intersection of roads' (yellow triangle with a black cross) visible in the video sequence warns of an intersection of roads of equal rank. According to § 5 para. 1 of the Regulation on road signs and signals, priority at such an intersection is not determined by signs, but results from general road traffic regulations (the so-called right-hand rule). Therefore, the answer that priority is established by signs is incorrect.
