swedish traffic stop

On Sept. 3, 1967, every car in Sweden came to a stop at 4:50 a.m., carefully switched from the left side of the road to the right, and proceeded at 5 a.m. The whole nation switched to right-hand traffic overnight. And to the planners’ immense credit, no fatal accidents were associated with the change, and accident rates went down in the year that followed.
