Today it is very difficult to imagine traffic rules without the main tool for streamlining traffic, which is a traffic light. It is designed to adjust and facilitate both vehicular and pedestrian traffic. There are different traffic light signals, depending on their functions. Although they are similar to each other, they have certain nuances that must be remembered.
A traffic light is an optical signaling device that is designed to regulate the movement of cars, bicycles and other Vehicle as well as pedestrians. It is used in all world states without exception.
Interesting! Previously, there was no green light in traffic lights in Japan. It was replaced by blue. But scientists have proven that green is more acceptable to human eyes.
The most common are three-color traffic lights with round signals: red, yellow and green. Traffic rules in some countries require the use of orange traffic lights instead of yellow ones. Signals can be placed both vertically and horizontally. If no other special traffic lights or additional sections are provided, then they regulate the movement of all types of transport, as well as pedestrians. Next, we will consider different kinds traffic lights, from everyday to special ones.
Such a traffic light has, as a rule, three colors, arranged in order: red, yellow, green - from top to bottom or from left to right. Such traffic lights are installed at intersections. They are designed for the simultaneous passage of all types of transport in all directions permitted by traffic rules. They are also installed at regulated pedestrian crossings located between intersections. It is allowed to install such a traffic light on railway crossing in settlements, at the intersection of the road with tram lines, in front of the cycle path and the carriageway. They can also be seen where the roadway narrows to allow oncoming traffic to pass alternately.
Interesting fact!The first three-section traffic light was installed in Detroit in 1920.
Traffic lights with two sections are used to regulate the flow of traffic in the territories of industrial enterprises and organizations, as well as during the narrowing of the roadway to organize a single-lane reverse traffic flow.
Such a one-color traffic light is found at unregulated intersections and pedestrian crossings.
Traffic lights can also be equipped with additional sectional sections with arrows or arrow contours. They regulate the movement of traffic in one direction or another. Such traffic lights work, according to traffic rules, in the following way: the contours of the arrows on all signals of a conventional three-color traffic light mean that its action extends only in one specified direction.
An additional section of a traffic light with a green arrow on a black background allows traffic according to the traffic rules, but does not provide advantages during the siding. Sometimes you can find an always burning green signal, which is made in the form of a plate with a solid green arrow. This means according to the traffic rules that the turn is allowed, despite the prohibitory traffic lights.
Such traffic lights are installed in those places where it is necessary to organize conflict-free traffic at intersections. If one of these traffic lights turns green, then when crossing the intersection, you can not give way. In order not to arise emergencies, personal traffic lights are placed above each lane, which show the direction of movement that is allowed from a particular lane.
Reversing traffic lights are used to regulate traffic along the lanes of the carriageway. These are dedicated band control knobs. At such traffic lights, from two to three signals can be placed: a red signal in the form of the letter "X" prohibits movement in a particular lane. The green arrow, which is directed down, on the contrary, allows movement. The yellow diagonal arrow indicates that the lane mode has been changed and indicates in which direction you need to leave it.
Typically, such traffic lights have only two types of signals: The first one allows, the second one forbids. As a rule, they correspond to green and red colors. The signals themselves can be different shapes. Often they are depicted as a stylized silhouette of a person: standing red and walking green. For example, in America, the prohibition signal is made in the form of a red raised palm, meaning "stop." Sometimes inscriptions are used: red “stop” and green “walk”. In other countries, respectively, in other languages.
Traffic lights with automatic switching are installed on highways with busy traffic. But there are times when you can switch the traffic light by pressing a special button, which allows you to cross the road for a certain time. Modern traffic lights for convenience are equipped with a digital countdown display. For blind people, sound devices are mounted in traffic lights.
A traffic light for a tram, as a rule, is placed in front of areas with limited visibility, long ascents and descents, at a tram depot and in front of arrows. There are two types of traffic lights for the tram: green and red. They are installed either to the right of the tracks, or hung in the center above the contact wire. Basically, such traffic lights notify tram drivers about whether the path is busy further or not. They do not regulate the movement of other vehicles and are purely individual. Their work is built automatically.
Round lights mean the following: a static green signal allows the movement of vehicles or pedestrians, and a flashing green traffic light means that a prohibition signal will light up soon, but traffic is still allowed.
Interesting fact!In general, residents of large cities spend about six months of their lives waiting for a traffic signal to pass.
What does a yellow traffic light mean? It warns that the prohibiting signal will be replaced by an enabling one or vice versa, and for the duration of its action prohibits movement. A flashing yellow traffic light means that the section of the road on which this traffic light is located is not regulated. If it is located at an intersection and operates in this mode, then the intersection is unregulated. Drivers are guided by those articles of the traffic rules, which stipulate the passage of unregulated intersections. A static and flashing red signal prohibits movement in any direction.
Red and yellow traffic lights burning at the same time indicate that it is forbidden to move further, and the green light will soon turn on. The white-moon signal of the traffic light informs that the alarm is working, and you can continue driving. Such traffic lights are installed on tram and railway tracks.
Traffic lights that look like arrows mean the following: red, yellow and green arrows mean the same as round signals, only they act in a certain direction. An arrow that points to the left also allows a U-turn, unless this is prohibited by the corresponding traffic sign next in priority.
The green arrow of the additional section has a similar meaning. If this signal is turned off, or the red outline is on, then movement in this direction is prohibited. If the main green signal has a black outline arrow, then this means that there are other directions of movement than those indicated by the additional section.
rules traffic have the following priority: the main one is the traffic controller, then the traffic light, then the sign and then the markings. The signals of the traffic controller have priority over traffic signals and traffic signs. They are mandatory. All traffic signals, except for flashing yellow, are more significant than road signs. All road users are obliged to follow the instructions of the traffic controller, even if they contradict traffic lights, signs and markings.
The capital of Germany has a traffic light with thirteen signals. It is not so easy to understand his testimony right away.

As you know, you can only cross the road in the places provided for this and only at the green traffic light. But traffic lights appeared at our intersections not so long ago, before traffic controllers were involved in coordinating traffic. Who owns the palm? Today, on the Birthday of the Traffic Light, we will deal with this issue.
The first who thought to install a traffic light at an intersection to adjust traffic, was John Peak Knight, a Londoner and specialist in railway semaphores. The first traffic light designed by him was installed in the British capital on December 10, 1868 near the Houses of Parliament.
Switching signals was carried out manually using two semaphore arrows. IN horizontal position they signaled "stop", and lowered at an angle of 45 ° - movement with caution. So that at night it was possible to identify the signal given by the arrows, a rotating gas lamp was used, which shone red or green.
In 1910, Ernst Sirrin of Chicago developed and patented the world's first automatic system switching traffic lights. His traffic lights had two inscriptions Stop and Proceed without illumination.
Just a couple of years later, in 1912, a resident of Salt Lake City, Utah, whose name was Lester Wire, created the world's first electric traffic light, with two round signal lights of red and green. For unknown reasons, Vayr did not patent his invention.
The next name in traffic light history is James Hogue. On August 5, 1914, the American Traffic Light Company installed four electric traffic lights designed by Hog at the intersection of 105th Street and Euclid Avenue in Cleveland.
Traffic lights were equipped with two light signals - red and green, and when switching they gave a sound signal. The whole system was controlled by a policeman who sat in a specially equipped glass box at the crossroads.
Six years later - in 1920 - traffic lights were installed in Detroit and New York, on which a yellow signal appeared. The people who developed them did not know each other: William Potts from Detroit and John F. Harris from New York.
Similar traffic lights were installed in 1922 in Paris at the intersection of Rivoli Street and Sevastopol Boulevard, as well as in Hamburg at Stephansplatz Square. In 1927, the same traffic lights appeared in Wolverhampton, England.
Often, the American inventor Garrett Morgan, who received a patent for a traffic light in 1923, is often mentioned as the first inventor. original design. The first countdown traffic lights appeared in France in 1998.
Concerning Soviet Union, the first traffic lights were installed here in the early 1930s. First, the traffic light appeared at the intersection of avenues on October 25 and the Volodarsky city of Leningrad (modern Nevsky and Liteiny avenues in St. Petersburg) on January 15, 1930. In Moscow, the first traffic light began work on December 30 of the same year at the corner of Petrovka and Kuznetsky Most.
The most widely used street and road traffic lights. Among them, automobile and traffic lights for pedestrians stand out - these varieties are most often found on the roads of the whole world.
Automobile traffic lights. As a rule, there are traffic lights with round signals of three generally accepted colors: red, yellow and green. The order of colors is strictly regulated. If the signals are arranged vertically, then red is always on top, and green is on the bottom. If the traffic light is horizontal, then the red signal will be located on the left, and the green one on the right. Additional sections with arrows are often hung on car traffic lights.
A yellow signal almost everywhere means this: it is allowed to pass the stop line, but it is necessary to slow down when entering a section protected by a traffic light, ready for the traffic light to switch to red. This signal can also be orange.
Traffic lights for pedestrians installed in the immediate vicinity of the established transitions. There are usually only two signals on them - forbidding and allowing. Appearance they may differ. The most common signals are in the form of a silhouette of a person - standing or walking.
In some countries, in the USA for example, the red signal is made in the form of a raised palm. Sometimes, instead of men and palms, the inscriptions "Go" and "Do not go" are used. In Oslo, two standing red human figures are used as a traffic signal forbidding pedestrians.
Why such difficulties? This is done for the convenience of people with poor eyesight, as well as for those who have difficulty with color discrimination (color blindness). In addition, traffic lights different countries equipped with an audible signal.
What are traffic lights made of? There are several possible designs traffic lights. The first option is traffic lights on incandescent lamps or halogen lamps. Their design includes:
In Russia there is a monument to a traffic light.
It was installed in Novosibirsk in 2006.
At first glance, traffic lights are all very simple, and we all know them from childhood. Red - stop, yellow - get ready, green - go. This is a very simple rule. In this article, we'll take a deeper look at this rule within the .
6.1. Traffic lights use green, yellow, red and white-lunar light signals.
Depending on the purpose, traffic light signals can be round, in the form of an arrow (arrows), a silhouette of a pedestrian or a bicycle, and X-shaped.
Traffic lights with round signals may have one or two additional sections with signals in the form of a green arrow (arrows), which are located at the level of the green round signal.
Traffic signals of white-moon color, in the form of a silhouette of a pedestrian or a bicycle and X-shaped, we will not consider in this article.
6.2. Round traffic lights have the following meanings:
- Green signal allows movement;
- A green flashing signal allows movement and informs that its time expires and a prohibition signal will soon be turned on (digital displays can be used to inform drivers about the time in seconds remaining until the end of the green signal);
- The yellow signal prohibits movement, except for the cases provided for in paragraph 6.14 of the Rules, and warns of the upcoming change of signals;
- A yellow flashing signal allows movement and informs about the presence of an unregulated intersection or pedestrian crossing, warns of danger;
- A red signal, including flashing, prohibits movement.
The combination of red and yellow signals prohibits movement and informs about the upcoming green signal.
This paragraph of the SDA describes round traffic lights. The most common traffic light, which is most often found on the roads.
6.3. Traffic light signals made in the form of arrows of red, yellow and green colors have the same meaning as round signals of the corresponding color, but their effect extends only to the direction (directions) indicated by the arrows. At the same time, the arrow that allows a left turn also allows a U-turn, unless this is prohibited by the corresponding road sign.
The green arrow in the additional section has the same meaning. The switched off signal of the additional section means the prohibition of movement in the direction regulated by this section.
The first thing you should pay attention to is that the signals are made in the form of arrows, i.e. the arrow is the signal. The signal is not round. Traffic lights with a contour arrow do not fit this definition, and clause 6.3 of the SDA is not applicable to them.
Second important point, traffic light signals made in the form of arrows regulate only indicated directions. For example, if the red arrow to the right is on, then movement is prohibited only to the right, movement straight ahead, turning left and turning around are not regulated by this signal.
Similarly with the green arrow signal, but only on condition that the arrow is in the main section of the traffic light. It is very simple to determine, for example, at night, whether this is the main section of the traffic light or the additional one - if the section is additional, then some signal must be on in the main section of the traffic light, if there are no other signals besides the arrow, then this means that the arrow is in the main sections.
6.4. If a black contour arrow (arrows) is applied to the main green signal of the traffic light, then it informs drivers about the presence of an additional section of the traffic light and indicates other permitted directions of movement than the signal of the additional section.
This paragraph describes the purpose of the outline arrow of a traffic light signal. We see that the contour arrow can only be applied in the main section, and only on the green traffic light, and unlike the signal in the form of an arrow, the contour arrow allows movement only in the indicated directions. Movement in other directions is prohibited.
On this we could finish our material, if not for one very common situation in practice. We often come across a traffic light with such a signal:
Before us is a traffic light with an additional section and a round signal. It would seem that, according to paragraph 6.3, it is forbidden to move in the direction regulated by this section.
But let's take a look:
Thus, at this traffic light signal, according to clause 6.2, movement is allowed in all directions, unless otherwise prohibited by signs or markings.
Answer of the Ministry of Internal AffairsLet's summarize briefly:
And this is how the TV program “Main Road” on NTV sees the situation.
Road to you without obstacles!
This lesson is prepared for first-graders as part of general education on road safety. General education classes are held according to the additional educational program “Competent Pedestrian” once a week for 45 minutes.

Introduction to the topic of the lesson:
Teacher: Hello guys! Today we will start our lesson by solving a rebus.
Children solve the rebus "Traffic light"
Teacher: That's right, traffic light. Can you solve the riddle?
- Yermoshka stands
On one leg
blinking eyes,
Pedestrians and transport
That stops
That allows you to move.
(Traffic lights)
The children solve the riddle.
Conversation "What is a traffic light?"
Teacher: And this is also a traffic light, right! What does the word "traffic light" mean, what do you think? (children's answers). A traffic light is a "bearer of light".
What is a traffic light for? (children's answers). A traffic light is needed to regulate the movement of pedestrians and vehicles.
I wonder how the first traffic lights appeared ... It happened a long time ago, when there were not even cars yet. Horse-drawn carts and carriages drove along the streets of cities and roads. And then there were accidents. Pedestrians walked wherever they please, because there were no traffic rules yet!
There was a need to restore order on the streets and roads so that there were no accidents and the lives of pedestrians were not endangered. It was then that they came up with the first traffic light. He was very simple (the layout of the first traffic light is demonstrated), in the form of a disk with two colors - red and green, and an arrow. A person controlled the traffic light, he simply moved the arrow from one color to another, and road users knew to move it or stand still.
But the traffic light with two colors was not convenient, because. people did not have time to understand at what point they can already start moving. There was often confusion. Then there was a traffic light with three colors. The third color - yellow, became intermediate, it meant - “prepare to move. Such a traffic light stood on a “leg”, that is, on a rack (demonstration of a traffic light model and the principle of its operation). For it to work, a person was also needed who, with the help of chains, lifted a disk with either red, or yellow, or green.
Teacher: And now, guys, we will get acquainted with modern traffic lights. Today, traffic lights are electric.
Traffic lights are transport, bicycle and pedestrian (shows the types of traffic lights on the stand, explains their purpose). Please note that the traffic and bicycle traffic lights have three signals, while the pedestrian one has only two.
What is on a bicycle traffic light? On a pedestrian? (children's answers).
What is a man doing at a red traffic light? And on green? (children's answers).
What does each color of the traffic light tell us? (children's answers).
- Well done, you know the language of traffic lights! (a poster is shown “What do the colors of the traffic light mean?”,<рисунок 2>):
Teacher: Guys, let's think together why these three colors are at the traffic light? After all, they were probably not chosen by chance ...
Why does the red color tell us that we need to stand? (children's answers).
Right. Red is the color of danger. What is red (blood, pain, fire ...).
And what does green mean? (children's answers). Well done! This is the color of calm. Green grass, foliage, we relax in the summer among the greenery in nature and feel relaxed, calm and safe.
Well, what does yellow mean, what do you think? (children's answers). Yellow is the color of attention, it is a signal, a warning. Get ready! Attention! For example, a yellow, bright sun. It can be kind, warm, affectionate. But if you stay in the bright sun for too long, you can get burned. So, you need to be careful, be ready. Or dandelions - because they are very bright, they immediately attract attention in the green grass. That's how it is yellow traffic light tells us “Attention! Be ready!".
Game "Red, yellow, green"
Teacher: Guys, now we will play a game. It will help us remember what the colors of the traffic lights mean and learn to act in accordance with them.
I will show you cards with traffic light colors, and you will do the exercises:
- on red - take a step back,
- on yellow - squat,
- on green - marching in place.
Teacher: Sometimes, in special situations, traffic is not controlled by a traffic light, but by a person in uniform. This is a traffic police inspector.
He makes movements with his hands using a rod. These signals correspond to traffic signals. See what the traffic controller's baton looks like (a model of a wand is demonstrated).
Here it is on the pavement
Tall, slender guard.
Turns, turns his head
To all passers-by he says:
-The way is now open for you!
All gone? Now – Attention!
The sign is different and the path is closed!”
(teacher demonstrates the signal of the traffic controller using the model of the baton.)
Solving practical problems (situations)
Now we will approach the layout of the city and see how the traffic light and traffic controller work (explanation and solution of practical problems on a desktop magnetic stand).
Practical task “Color the traffic light”
Teacher: I will give you cards with the image of three traffic lights. , < figure 3 >. But these traffic lights are not painted. You need to color them so that the first is red, the second is yellow, the third is green. Then you need to color the men so that the color of the men matches the color of each traffic light (children perform the task individually, after completion of the work, the task is discussed and checked, the teacher demonstrates a correctly colored card,<рисунок 4>).
Summary of the lesson
Teacher: So, guys, let's summarize our lesson, remember everything we talked about today and answer the questions:
What are traffic lights?
What are the colors of traffic lights?
What are the colors of a pedestrian traffic light?
What do the colors of traffic lights mean?
What is the name of the person who regulates traffic instead of a traffic light?
What is in the hands of the regulator? (children answer, the teacher summarizes and underlines the correct answers).
Well done boys! We have done a good job today. I hope that all of you will observe the Rules of the Road, and most importantly, cross the street correctly at traffic lights. Remember, traffic lights are our best friend!
February 5, 1952 on one of the streets of New York was installed the first traffic light for pedestrians. After all, before that, only cars were considered road users. It was a real breakthrough in the organization of traffic, but far from the final point in the development of regulatory infrastructure. And today we will talk about the history of traffic lights from their introduction in 1868 to the most recent and promising developments of our time.
This traffic light was controlled manually - a street policeman regulated the appearance on the scoreboard of a horizontal (stop) and an arrow inclined at an angle of 45 degrees (move) that regulate the movement of horse-drawn vehicles and pedestrians. At night, when visibility did not allow to see the arrows from afar, they were replaced by gas lamp with red and green lenses.
