the day sweden changed from left to right
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–right political spectrum The spectrum is distinguished by position with regard to a social order present in a particular culture, with the left favoring transformation or dissolution of such structures as part of a general transformation of that culture and the right resisting such transformation, the speed with which it takes place, or advocating rollback of change that has taken place. In Europe, left and right reflect mainly class-issues, with the Left seeking more redistributive policies. In the US, social policies are also important, with the Left promoting social reform and the Right defending conservative Christian values.
