Garrett Morgan invented the traffic light in the early 1920s while he was living in Cleveland, Ohio. His design aimed to improve road safety by introducing a system to control the flow of traffic at intersections. Morgan's innovation came as a response to the increasing number of vehicles on the road and the need for better traffic management. His traffic signal featured a three-position system, which included a warning signal, an innovation that significantly contributed to road safety.
