Le Droit ou Le Gauche... UNIQUELY DUAL-ING Á LA FRANCAISE
It's not a giggling matter if you are a French motorist caught up in an anarchic traffic argument between two mayors of adjacent towns, who both think they have sole rights to your right of way.
Both mayors decreed a particular street one-way for traffic, but in opposite directions. The panoply of the French State has had to intervene. The State has designated the street for two-way traffic!
All's well that's ends well......peut etre (Perhaps).
