Intersection in traffic

In most of Continental Europe, the traffic rule is to give priority to the right, but this may be altered by signs or road markings, and does not apply at T-shaped junctions in some of these countries, such as France. There, priority was initially given according to the social rank of each traveler, but back in the days in the life of the automobile this rule was deemed impractical and substituted with the priorité à droite (priority to the right) rule, which still applies. At a traffic circle where priorité à droite is not overridden, traffic on what would otherwise be a roundabout paves way to traffic entering the circle. Most French round-abouts now have pave-way signs for traffic entering the circle, but there remain some notable exceptions that operate on the outdated rule, such as the Place de l'Étoile around the Arc de Triomphe. Traffic at this intersection is so disordered that French insurance companies deem any accident on the round-about to be equal liability.[1] Priority to the right where used in continental Europe may be altered by an ascending hierarchy of markings, signs, signals, and authorized persons.
