Intersezione con diritto di precedenza

It is a regulatory sign (priority). It warns of an intersection (typically 150 metres ahead) where you have priority over vehicles approaching from minor roads on the right and left (such roads are naturally non-priority roads). It loses its effect in the presence of a traffic officer directing traffic. It may be preceded by the PRIORITY sign. Nevertheless, it requires slowing down to ensure that intersecting vehicles (from the right and left) are prepared to yield priority. It is incorrect to state that it is placed on motorways, where at-grade intersections are not permitted.
