From childhood, we are familiar with traffic lights, but in detail the features of their work are studied only by drivers. They know what a flashing green traffic light means and what pitfalls are hidden behind these artificial traffic controllers. In paragraph 6 of the SDA (except for paragraphs 6.10-6.12) talks about how to navigate by traffic lights, and what types of these devices exist.
Traffic lights use red, green, yellow (orange) and white signals. They themselves can be in the form of arrows, round, in the form of a silhouette of a cyclist or a pedestrian, x-shaped.
Round types of road traffic lights can be equipped with additional sections with a luminous green arrow. As a rule, they are located at the level of the round element of the corresponding color at the main traffic light.
Each color of a traffic light, according to the rules, has a certain meaning. Color designations are as follows:
- Green - you can go. And what does the flashing green traffic light mean, what should the driver do? This version of the signal informs road users that the red light will turn on in the near future. On some devices, flashing is accompanied by a countdown.
- Yellow is the forbidden color. With it, movement is prohibited, except for the situations provided for in paragraph 6.14.
- Blinking yellow allows participants to start moving and indicates that the established traffic signs are currently operating at this intersection.
- Red color prohibits movement.
- Red and yellow signals turned on at the same time indicate that the green signal will soon turn on and it will be possible to start moving.
Some traffic lights have green, red, yellow arrows. They have the same meanings as the round variants, but their effect only extends in the direction indicated by the arrows. The arrow indicates the direction of movement, in this case it allows a left turn, it also allows you to turn around, provided that there are no signs prohibiting this action.
And what does the flashing of a green traffic light with an arrow mean? Flashing indicates that the red light will soon turn on and the movement will need to be stopped.
Traffic lights with arrows are often equipped withadditional section. If the signal of this part of the traffic controller is turned off or on, but a red outline is visible, then it is forbidden to move in the direction where the section points.
Items 6.4 and 6.5
The meaning of a traffic light changes if it has a black arrow. It informs about the additional section and indicates in which directions it is allowed to move.
Some traffic lights depict a pedestrian. It only applies to cyclists and pedestrians. Red prohibits movement, green permits.
Cyclists are controlled by a smaller traffic light and an additional sign indicating that this traffic light is for cyclists.
Items 6.6 and 6.7
Sometimes traffic lights are set so that drivers get into blind spots. In these cases, they are supplemented with a special sound signal.
X-shaped traffic lights are used to regulate reverse traffic. When a signal is prohibited, a red “X” symbol is displayed. In those moments when traffic is allowed, the traffic light shows a green arrow pointing down. According to traffic rules, reverse type traffic signals act on the lane above which they are installed.
In addition to the main signals, reversing devices can be supplemented with yellow. When turned on, drivers are informed that there will soon be a signal change or that they need to change lanes to the lane indicated by the yellow arrow.
Items 6.8and 6.9
To regulate the movement of trams and other route vehicles moving along a special, dedicated lane, one-color traffic lights with four round white elements are used. Such devices are shaped like the letter "T".
Each combination of switching signals has its own designation. So, when you turn on all sections at the same time, you can continue to move in any direction. If only the top three sections are lit, then movement is prohibited.
White-moon signal, located at the railway crossing, regulates traffic through it. So, when the traffic light is flashing, the transport cannot pass through the crossing. When the signal is turned off, it is allowed to pass through the railway.
Knowing what a flashing green traffic light means, drivers should not start moving, as this indicates that the red light is about to turn on.
On the prohibition signal, vehicles must stop moving, stopping at the stop line. If it is not there, then the stop is performed:
- just before the intersection;
- before traffic lights, without obstructing other road users;
- before the railway crossing.
Stopping at a pedestrian crossing is prohibited.
There are situations when drivers start a maneuver and cannot stop without sudden braking, they can continue driving. If at this time there are pedestrians on the roadway, they are obliged to clear the roadway by stopping on the line dividing the vehicle flows.
Items 6.15 and 6.16
Drivers are required to comply with all requirements of road signs, traffic lights and the traffic controller. If the requirements of road signs and traffic lights contradict each other, then drivers must navigate by traffic lights. In case of violation of traffic rules, drivers will be punished in the form of an administrative pen alty (fine), and in some cases, deprivation of a driver's license.
