when did sweden stop driving on the left
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]
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.
