What year was the first traffic light used in the USA?
1920
Here's a little trivia for you:
When motorcars were introduced to the US in the late 1890s, Police Officer William Potts used railroad signals for street traffic, adding the amber light. His electric traffic lights were installed in 1920 in Detroit, Michigan, USA. They were manually controlled. The first automatic traffic light was invented later in 1920 by Garrett Morgan and first used in Cleveland, Ohio, USA.
