Garrett Morgan was in his early thirties when he patented his version of the three-position traffic signal in 1923. He modified the existing traffic signal design to include a warning position, improving safety and efficiency on the roads.
Garrett Morgan invented the traffic light in 1923. The exact month and date of the invention was not documented.
The three-way traffic light was invented by Garrett Morgan in 1923. He patented the design for the T-shaped traffic signal that included a mechanism to control traffic flow at intersections.
JP Knight invented the traffic light in 1868
Most sources say he invented it around 1922, and applied for a patent in late 1923.
Garrett Augustus Morgan invented the traffic light after witnessing a traffic accident, which inspired him to create a device to regulate traffic flow and reduce accidents at intersections. His idea was to develop a signaling system that would provide clear instructions to both drivers and pedestrians, thus improving safety on the roads.

Garrett Augustus Morgan was the African American who invented the three way automatic traffic light.
Garrett A. Morgan invented the three-position traffic signal in 1923. This device was an early version of the modern traffic light, which helped regulate traffic flow and increase road safety.
The four-way traffic light, also known as the modern traffic signal, was invented by Garrett Morgan in 1923. Morgan was an African American inventor and entrepreneur who patented his design to help improve road safety and reduce traffic accidents.
In early 1922, inventor Garrett Augustus Morgan designed a cross shaped traffic signal, for which he submitted a patent application on February 27 of that year. The patent was granted on November 20, 1923.
