Traffic lights change their colors in the same order every time. In most English-speaking countries, traffic lights usually change in this order:
Red light on: This tells drivers to stop.Green light on: This means the driver can start driving or keep driving.Yellow light on: This tells drivers to stop when it is safe to, because the light is about to turn red.
Garrett Morgan, an African-American inventor, invented one of the first traffic lights. He was one of the first people to get a patent for a traffic light.
William Potts, a police officer, invented the first traffic light with three colors.
