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.
Left- and right-hand traffic Historically there was less consistency in the relationship of the position of the driver to the handedness of traffic. Most American cars produced before 1910 were RHD.[7] In 1908 Henry Ford standardised the Model T as LHD in RHT America,[7] arguing that with RHD and RHT, the passenger was obliged to "get out on the street side and walk around the car" and that with steering from the left, the driver "is able to see even the wheels of the other car and easily avoids danger."[47] By 1915 other manufacturers followed Ford's lead, due to the popularity of the Model T.[7]
