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.
How long is red light traffic?
There is no specific length of time for a red light. Traffic engineers make that determination according to the flow of traffic.
Why did Garrett Morgan make the traffic light?
Because he kept getting into traffic accidents.
What makes the traffic light so important?
Traffic lights are important because they regulate traffic safely and make movement of traffic smoother and faster at intersections.
What do the holes on the curved board of the traffic light support?
to make it lighter
How do you make a turn at an intersection?
Answer about left turnsCarefully, unless you are in China. The person turning left must yield to oncoming traffic. At a regular traffic light, you should enter the intersection. When the oncoming traffic stops for the red light you Amy proceed in order to clear the intersection.
Is it illegal to accelerate through a yellow traffic light?
It is generally not illegal to accelerate through a yellow traffic light as long as you are able to safely make it through the intersection before the light turns red. However, you should always exercise caution and be prepared to stop if the light changes.

When is it legal for all traffic to make left hand turns when traffic light is red?
It is legal for all traffic to make left-hand turns when the traffic light is red if it is a designated "permissive turn" intersection that allows left turns on red after stopping and yielding to oncoming traffic. These intersections are rare and typically have signs indicating this permission. Otherwise, making a left turn on a red light is generally illegal unless otherwise specified by local traffic laws.
Was the inventor of the traffic light an African-American?
Debatable as to who is the inventor. Two men are credited. You decide. 1. The very first traffic light was a revolving gas lantern with red and green lights installed in a London intersection in 1868, before the advent of automobiles. A later version of the traffic light based on railroad signals was installed in Detroit, Michigan, in 1920. But we have Garrett Augustus Morgan to thank for the modern version and first patent of this traffic-stopping invention. The son of former slaves, Morgan was born in 1877 in Kentucky. He later moved to Cincinnati and then Cleveland, where he owned and operated a sewing-machine repair business and earned quite a reputation as a technician. A multi-talented businessman, Morgan went on to establish the newspaper The Cleveland Call. In early 20th century Cleveland, as in other major U.S. cities, the roads were clogged with pedestrians, bicycles, animal-drawn wagons, and those newfangled automobiles. There were no traffic laws to speak of, and chaos ruled the streets. Accidents were frequent. After witnessing one such traffic accident, Morgan felt compelled to improve the situation. The result? The precursor to the modern traffic signal, patented on November 23, 1923. Not quite your contemporary street light, "The Morgan traffic signal was a T-shaped pole unit that featured three positions: Stop, Go and an all-directional stop position. This 'third position' halted traffic in all directions to allow pedestrians to cross streets more safely." His light was used throughout North America before being replaced by today's familiar red/yellow/green traffic lights. Morgan eventually sold the rights to his invention to General Electric. He also received a government citation for his invaluable invention. 2. The world's first traffic light came into being before the automobile was in use, and traffic consisted only of pedestrians, buggies, and wagons. Installed at an intersection in London in 1868, it was a revolving lantern with red and green signals. Red meant "stop" and green meant "caution." The lantern, illuminated by gas, was turned by means of a lever at its base so that the appropriate light faced traffic. On January 2, 1869, this crude traffic light exploded, injuring the policeman who was operating it. 3. 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.
