8.7.3. Traffic light signals have the following meanings:
A signal in the form of an arrow that allows a left turn also allows a U-turn if it is not prohibited by road signs.
A signal in the form of a green arrow(s) in the additional section(s), switched on together with the green traffic light signal, informs the driver that he has priority in the direction(s) of movement indicated by the arrow(s) over vehicles moving from other directions;
f) a red signal, including a flashing one, or two red flashing signals prohibit movement.
A signal in the form of a green arrow(s) in the additional section(s), together with a yellow or red traffic light signal, informs the driver that movement is permitted in the indicated direction, subject to the unhindered passage of vehicles moving from other directions.
A green arrow on a sign installed at the level of a red traffic light with a vertical arrangement of signals allows movement in the indicated direction when the red traffic light is on from the rightmost lane (or the leftmost lane on one-way roads), subject to the provision of priority in traffic to its other participants moving from other directions to a traffic light signal allowing movement;

16.9. While driving in the direction of the arrow turned on in the additional section simultaneously with a yellow or red traffic light, the driver must give way to vehicles moving from other directions.
When driving in the direction of the green arrow on the table installed at the level of the red traffic light with vertical signals, the driver must take the extreme right (left) lane and give way to vehicles and pedestrians moving from other directions.
When engaging in cycling and driving on roads for cars, mounting rear-view mirrors on a bike will significantly increase safety. When cycling exclusively on pedestrian roads, this accessory is not necessary.
Installing rear-view mirrors on a bicycle was not used immediately. This idea of enlargement came to an American racer at the beginning of the 20th century, when he saw a device on a cart.
Serial production of rear mirrors began in 24 of the 20th century. This technology has become widespread due to its convenience.
Installing the device allows you to ensure the safety of the maneuver, for example. This measure allows you to determine the number of cars and bicycles behind before reducing the speed or stopping the bike completely.
Most mirrors have a fish-eye effect, which significantly increases viewing angles. The disadvantage of the device is that it distorts the true distance between objects, but the cycling enthusiast quickly adapts to this type.
The reverse side of the mirror has a streamlined shape, which improves.
Important! A rearview mirror may be useless if its use is neglected.
Bicycles and scooters
Accessory requirements
Each bicycle owner should adjust the mirror in accordance with the following requirements.
- The device should make it possible to view horizontal roads up to the horizon line.
- The shape of the accessory and the method of its installation should ensure high clarity of the displayed information with slight vibrations and jumps in the steering wheel.
- Distortion of color shades, as well as the shape and distance of objects is unacceptable for rear-view mirrors. It is recommended to avoid such models.
- The closer the accessory is to the rider’s face, the wider the view. It is recommended to purchase models with a long bracket.
You should also pay attention to safety.
- There should be no sharp pointed edges on the rear view mirror; sharp edges are not allowed on the mount or body of the fixture.
- The housings of the accessory must be folded, this will avoid serious consequences if it comes into contact with the wall, vehicle or a pedestrian. Also, rear view mirrors should not protrude more than 20 centimeters.
- If a bicycle rear view mirror falls, the formation of fragments is unacceptable; in the event of a traffic accident, this jeopardizes the health of the cyclist.
What does it consist of?
Most models of rear view mirrors include the following elements.
- Housing and mounting of the device.
- Optical element.
- Design that allows you to adjust the position of the mirror.
Simple types of accessories are characterized by the immobility of the optical element relative to the bicycle. Position correction is carried out using one hinge.
Complex types of rear-view mirrors involve moving the device relative to the bike using several adjustment elements.
After testing for compliance with the above requirements, the accessory receives an indelible inscription or image indicating approval of the quality of the product.
The sign contains information about the class of the rear view mirror, the country that issued the approval, as well as an identification number. On the body there is a factory mark of the manufacturer of the device.
How it is fixed and types
Devices for mounting and securing mirrors lose reliability as they are used and gradually become loose. It is recommended to use devices that have a standard type of rear view mirror mounting.
There is a type of device that has an additional “fish eye” glued on.
However, based on most reviews, this feature is more of a hindrance than a help. The visibility of the standard reflective element is reduced. While driving, double reflection of objects only interferes with the process of recognizing cars and other vehicles.
Varieties are also distinguished based on the type of spraying of the reflective element. It is presented in two types, external and internal.
With the first type, applying a match to the surface of the mirror, the reflection will come into contact with the object. With internal spraying, a visible gap of 3 millimeters remains.
When choosing a rear view mirror, you should pay attention to the following features.
- The reflective element and other parts of the device must be free of any, for example, chips or cracks.
- High-quality seals are characterized by softness to palpation.
- The fastening elements are treated with zinc coating or other protective layer.
- The ends of the rear view mirror are covered with a special varnish material. In the absence of varnish, corrosion pockets will form when using the device.
The rigidity of the fastening can be checked by pressing the fastening against wood or any other dense surface. After this, you should hit the table with your fist, which will create a slight vibration of the furniture.
If there is interference in the reflection while driving on an uneven road, the image will also vibrate. It is not recommended to check the degree of rigidity of the bracket on mirror surfaces.
To determine the quality of the hinge, you need to turn the control knobs. The reflective element must rotate gradually; jamming or jerking during movement is unacceptable.
Holding the accessory mount, lightly press on the edge of the mirror. Glass in a high-quality device moves under a load of 2 kilograms or more. With weaker indicators, the mirror settings will change as the vehicle moves.
To get rid of dirt you should. The use of rags is unacceptable; this will damage the reflective surface of the device.
When riding a bike along the road in the same direction, you often have to turn your head back. Especially before performing a maneuver. It is very uncomfortable.
Therefore, mirrors on a bicycle are a really convenient thing.
But it should be noted that not all mirrors. For example, those sold on Aliexpress are complete crap, for the simple reason that they are not spherical, not panoramic. At least the ones I ordered were ordinary mirrors. This is the first thing.
Secondly, some of the mirrors offered on Aliexpress are not only not spherical, but also very small.
Today I’ll tell you how to make a really “working” mirror, and cheaply. It will look something like this:
It is put on the edge of the grip:
For this we need:
The mirror itself is an additional viewing mirror that is attached with double-sided tape to the side mirrors of gazelles. You can buy it at any auto store. Today I bought one of these for 90 rubles. But it's expensive. In the previous year, 2015, I bought a pair, apparently for 30 rubles.
Fastening from a catafot. My previous bike came with standard reflectors: red and white.
Something like this, photo not mine.
They were on a removable mount.
Also - left photo.
If you don’t have such a reflector, you can buy a reflector with an adjustable bolt-on mount. I bought this for 50 rubles. All we need from him is the fastening.
This riveting is worse. Firstly, the extra knot is a bolt. Secondly, it is heavier.
An important point - before gluing, you should decide for which side this mirror will be intended. Since you need to glue the mirror not in the center, but slightly offset to the side. In this case I will make a mirror for right side. Therefore, I will move the mirror more to the right. If this is not done, the mirror will move less to the side and take up more space on the grip. The second photo shows that the mirror is slightly offset to the left.
So let's clean it up.
Apply glue in a thin layer.
We wait 10-15 minutes and press firmly.
It looks terrible, but there are options: either glue it more carefully, or find colorless glue, or clean it and paint it black. Personally, I'll most likely do the latter.
After the mirror dries, it is simply placed on the edge of the crips.
There is no point in screwing it there. The mirror is held quite firmly. By the way, another drawback of some mirrors from Aliexpress that are attached to the grip is shaking. Because They are attached using a rubber mount; when they move, they shake, which, of course, makes the whole picture shake.
In such a mirror everything is clearly visible. And it’s so good that you can see the left side of the road through the right mirror.
This is my old left mirror.
It's the same.
It is believed that rear-view mirrors were installed on horse-drawn carts. However, the name of the cab driver who came up with this idea was not preserved in history. For the first time such an accessory appeared on the car of racer R. Herraun in 1904. And bicycle manufacturers began to install mirrors en masse since 1924.
For a long time, bikes were equipped with viewing aids by default. But last years Manufacturers leave the installation of the mirror at the discretion of the user. Let's try to figure out whether a modern cyclist needs this accessory?
Why do you need a mirror on a bicycle?
A mirror makes riding safer because it makes it possible to assess the road situation behind the cyclist. If it is not there, you need to turn your head from time to time, but this method has serious disadvantages:
When you turn your head, you are distracted from your forward view.
When a cyclist looks back, his center of gravity shifts, because of this, the trajectory of movement even professional athlete deviates slightly in the other direction. In heavy traffic conditions this can lead to an accident.
You can only turn your head for a few seconds while driving; this is not always enough to assess the situation.
Most of the time you won't know what's going on behind you.
Because looking back is not always convenient, most cyclists install mirrors. This makes the trip safer. Experienced cyclists recommend combining the capabilities of the mirror and turning your head.
10 situations when a mirror is simply necessary
If you often drive on roads, then your safety depends on the ability to see what is happening behind you. A mirror is simply necessary for those who are in another country with an unusual direction of movement or where traffic rules are poorly observed.
If you have poor eyesight and you wear glasses rather than contact lenses, then it is worth installing a mirror. Those who wear glasses have limited peripheral vision because... There is no correction glass in this area. This means that you will see the situation worse from the side, and when you turn your head, you may not notice the car.
If you have hearing impairment. Those who drive without a mirror get Additional information about the approach of a car due to noise. If your hearing is impaired, the likelihood of not noticing the car increases.
For older people and those for whom turning the head is difficult for physiological reasons.
In case of fatigue during long trip. Of course, it is better not to ride if you are feeling unwell. But if you have not calculated your strength, then driving with a mirror will be safer. After all, a tired person is less attentive and less likely to look around to assess the situation on the road.
At night, a mirror is indispensable, because car headlights are clearly reflected in it and moving vehicles can be seen at a considerable distance.
While traveling with company. If you are riding with friends, family or a group of like-minded people, then the mirror will become a great assistant not only on the road, but also on rough terrain. It will help those who are driving ahead to make sure that no one is left behind.
For beginner cyclists and those who are just getting used to riding on the road. People who have little experience are more likely to lose their balance while driving and may find it difficult to look behind them without turning the steering wheel. In addition, it is psychologically difficult for a beginner to turn away from the road ahead and assess the situation behind in just a few seconds.
If you are riding with a child, a mirror will help make sure that everything is fine with the baby.
When driving on a bad road, uphill, etc., it can be important to control what is happening in front, which means turning your head in such a situation can disrupt the movement.
Features of cycling with a mirror
If you've never used a mirror, you'll need to get used to your new viewing aid before heading out on the road. It is better to first drive along park alleys and other safe places, looking in the mirror. This way you will learn to correctly determine the distance to an object, its speed and other details. This is especially important if you choose a fisheye model, which produces a slightly distorted image but covers a larger area.
Also, do not forget that mirrors on bicycles are small and have “dead spots”. These areas need to be identified and not forgotten. In addition, a beginner will need to get used to the presence of a mirror and try not to be distracted by it unnecessarily.
The quality of the mirror is the key to safety
To ensure safe skiing, you need to choose a high-quality mirror from good manufacturer. We will explain below how these models differ.
Image quality. A good mirror should not distort the color and shape of the object. Even a small defect can affect the correct perception of the road situation. When looking at an image in a regular mirror, curved lines or other artifacts should not appear; it is important that in spherical models all arcs are smooth, without flaws or waves. When vibrating, the image on a high-quality mirror must remain distinguishable, otherwise visibility will be difficult under rough road conditions.
The mirror position adjustment mechanism must be securely fixed to prevent changes in position during movement or jerking. Good design moves smoothly, without jerking or jamming. Otherwise, you won't be able to set up the most convenient overview.
The high-quality rubber gasket between the mirror and the body is elastic, which ensures an optimal fit. If this part is made of a hard material, over time the mirror will begin to become loose.
The product must be manufactured so that if broken, the fragments will not fly apart.
All these nuances are not always taken into account by manufacturers of inexpensive products, so we recommend choosing mirrors from specialized sports stores who monitor the quality of the products offered.
