Who invented the traffic light?
The traffic light, as we know it today, actually went through a few phases of invention.1868 - JP Knight created a signal based on red and green gas lamps. It took an officer to operate it. It exploded about one month later and injured the officer on duty.1912 - Lester Wire invented the first electric traffic light. It was also based off of the red and green system.1914 - James Hoge improved upon the system by adding a buzzer to notify drivers that the light would soon be changing colors.1920 - William Potts made a four way signal. Potts replaced the buzzer with a yellow light.1923 - Garrett Morgan added a mechanical linkage to allow officers to operate the signal from a distance.
Did Garrett Morgan invented the traffic light?
Yes, Garrett Morgan is credited with inventing the three-position traffic signal in 1923. His design included the "stop" and "go" signals, which later evolved into the modern traffic light systems we use today.
Who invented the first traffic light?
Police Officer William L. Potts of Detroit, Michigan, decided to do something about the problem caused by the ever increasing number of automobiles on the streets. What he had in mind was figuring out a way to adapt railroad signals for street use. Potts used red, amber, and green railroad lights and about thirty-seven dollars worth of wire and electrical controls to make the world's first 4-way three color traffic light. It was installed in 1920 on the corner of Woodward and Michigan Avenues in Detroit. Within a year, Detroit had installed a total of fifteen of the new automatic lights. ---- The world's first traffic light was operating in London, England, even before the first car was invented. Installed at a London intersection in 1868, it was a revolving gas-lit lantern with red and green signals. However, on 2 January 1869, the light exploded, injuring the policeman who was operating it. Obviously, a safer, more reliable system was required. In the early 1900s, Garrett Morgan of Cleveland, Ohio, developed the electric automatic traffic light. Originally based on a semaphore-system, it was William Potts (see above information) who developed the traffic lights become the red-amber-green lights they are today.
When was the 3 way traffic light invented?

Who invented the three way light switch?
William J. Newton is credited with inventing the three-way light switch in 1916. The design allows for a light fixture to be controlled from two different locations.
A flashing red traffic light at an intersection means?
Traffic approaching the light is to stop. If the way is clear, traffic can then proceed through the intersection.
Can you turn left on a one-way street when the traffic light is red?
No, you cannot turn left on a one-way street when the traffic light is red.

What can a three-way switch be compared to?
A three-way switch can be compared to a traffic intersection where multiple roads meet. Just as a three-way switch allows control of a light fixture from three separate locations, a traffic intersection allows vehicles to be directed from multiple directions. Both systems involve managing the flow of traffic or electricity from various entry points.
