when did france change to driving on the right
Left- and right-hand traffic In France, traditionally foot traffic had kept right, while carriage traffic kept left. Following the French Revolution, all traffic kept right.[9] Following the Napoleonic Wars, the French imposed RHT on parts of Europe.[citation needed] During the colonial period, RHT was introduced by the French in New France, French West Africa, the Maghreb, French Indochina, the West Indies, French Guiana and the Réunion, among others.
Dagen H Dagen H (H day), today usually called "Högertrafikomläggningen" ("The right-hand traffic diversion"), was the day on 3 September 1967, in which the traffic in Sweden switched from driving on the left-hand side of the road to the right.[1] The "H" stands for "Högertrafik", the Swedish word for "right traffic". It was by far the largest logistical event in Sweden's history.[2]
