The world’s first electric traffic signal is put into place on the corner of Euclid Avenue and East 105th Street in Cleveland, Ohio, on August 5, 1914.
In the earliest days of the automobile, navigating America’s roads was a chaotic experience, with pedestrians, bicycles, horses and streetcars all competing with motor vehicles for right of way. The problem was alleviated somewhat with the gradual disappearance of horse-drawn carriages, but even before World War I it had become clear that a system of regulations was necessary to keep traffic moving and reduce the number of accidents on the roads. As Christopher Finch writes in his “Highways to Heaven: The AUTO Biography of America” (1992), the first traffic island was put into use in San Francisco, California in 1907; left-hand drive became standard in American cars in 1908; the first center painted dividing line appeared in 1911, in Michigan; and the first “No Left Turn” sign would debut in Buffalo, New York, in 1916.
