Traffic Lights and Signals

When a traffic light blinks red it means 'yield,' so proceed as if it were a four way stop sign.

I've never heard of one blinking only yellow.

A green arrow showing same time as a red light proceed carefully in the direction of the arrow after yielding the right-of-way to other vehicles and perdestrians

It is a website that monitors the roadways for traffic!

For color blind people the traffic light would be upright and from top it would be.

Red

Yellow

Green.

An amber light is an amber-coloured traffic light, found in the UK, indicating that vehicles should stop unless it's unsafe to do so. The equivalent in the United States is the yellow light.

i do not have a clue what your talking about! why not define what you mean?

treat it like a 4way stopp

It changed history because it kept people from getting into car crashes

LED light source stability and energy saving

Yellow light

Yes, it was. The traffic light was first invented and used on December 10th 1868, this light unlike modern lights was hand operated by a police officer, which made it far less practical than that of the modern light. Eventually in 1912, the first known modern electric traffic light was used, this light used the red green light system. However these lights were rather simplistic using a two color red green system and as a substitute for yellow, a buzzer that alerted drivers of a color change. The first four way tri-color traffic light was created in 1920 police officer William Potts. And in 1922 another innovation came into play, in Houston Texas, the first interconnected automatic street light was deployed. However, generally from this time on their has been little more than style change, the shape, locations and computing systems have been updated, but the general concept has remained the same.

If a traffic light breaks most cities will assign a traffic cop to regulate traffic until the light can be fixed.

Well, the first one that was used was in 1912 in Salt Lake City by Lester Wire, but the first one permanently installed was probably one in Cleveland, Ohio, in 1914. It was installed by the American Traffic Signal Company. These first ones only had red and green lights (like previous ones that used gas lighting in England). The three color ones were developed in 1920.

On December 10, 1868, the first traffic lights were installed outside the British Houses of Parliament in London,

To find the acceleration, use Newton's second law: F = ma, where F is the net force, m is the mass, and a is the acceleration. Rearranging the formula to solve for acceleration gives a = F/m. Plugging in the values F = 4000 N and m = 1000 kg, the acceleration of the car is 4 m/s^2.

Unless the lane is specifically marked as "Right turn permitted without stopping", yes. In any case you would still be required to yield.

it means slow down or jail. that's all get it?

If you are approaching it and have time to apply your brakes before it turns red, apply your brakes and come to a stop. If it changes as you are too close to it to avoid slamming on youir brakes, for safety's sake pass through it - - but DON'T go through if it's going to turn red as you arrive at the intersection.

your not so bright

The traffic light became popular in the early 20th century as urbanization and automobile usage increased, leading to more complex traffic situations. The first electric traffic light was installed in 1914 in Salt Lake City, Utah, which offered a more efficient way to manage traffic flow compared to earlier mechanical signals. Its widespread adoption was driven by the need to enhance road safety and reduce accidents at busy intersections. By the 1920s, traffic lights had become a standard feature in cities around the world.

Yes; Traffic lights change colour on average every three to five minutes. Just stand at any traffic junction!
