Why you need to wear a seat belt physics. Seat belts: rules of use, whether it is necessary for passengers in the back seat to buckle up, when it is possible not to buckle up, etc.

1. All vehicles must be driven with dipped headlights or daytime running lights on. Even during the day.

Our Rules are gradually moving towards European rules. In particular, people in the Old World have long been accustomed to moving with the dipped beam constantly on and giving way at the entrance to the circle. Indeed, the included headlights make it possible to recognize an approaching car from a greater distance. True, judging by the number of cars moving with their headlights off in the month before the change was adopted, many people will have to change their habits.

2. All drivers and passengers are required to wear seat belts.

Comments website

This item does not apply to ordinary motorists: we were required to wear seat belts before. The exceptions were driving instructors and drivers of special services vehicles. But since even “driving instructors” and traffic police inspectors get into accidents, the legislative initiative to oblige everyone to use seat belts can be considered useful.

New cars will help to comply with the rules: in a significant part of new foreign cars, buzzers are installed to remind the driver that he left without wearing his seat belt. Drivers of domestic cars and used foreign cars (on which an impressive part of instructors teach driving) will have to control themselves.

3. The driver must give way to the pedestrian even if he has just entered the carriageway.

Comments website

Pedestrians must be allowed to pass. Giving way only to those who stepped on the "zebra" also makes sense. Thus, it will be easier for the traffic police to identify violators: previously, pedestrians who “did not let through” could justify themselves by the fact that a person did not walk, but stood on the roadway, and supposedly was not going to walk. Pedestrians themselves will not need to run across cars at the risk of their lives, but just step onto the roadway and be able to cross the road. True, it will be much more difficult for motorists to recognize whether a person is still on the sidewalk or already on the “zebra”: they will have, for one hundred percent certainty, to noticeably slow down in advance. It might save someone's life...

4. The "No Overtaking" sign now allows overtaking of slow moving vehicles and horse-drawn carts, as well as mopeds and two-wheeled motorcycles without a sidecar (PLEASE NOTE: if the road markings prohibit overtaking, it is IMPOSSIBLE to overtake the above vehicles and occupy their lane).

Comments website

With overtaking sluggish movers the situation is ambiguous. As strongly explained in the traffic safety department, you can only overtake vehicles marked with the appropriate sign and only when other sections of the rules (in particular, markings) do not prohibit this. Thus, it is impossible to get ahead of a slow-moving car without a reason, or a tractor without a slow-moving sign. But will legislators be able to force a tractor driver or wagon driver to mark his vehicle?

5. In the case when the sign "Roundabout" is installed before the intersection, the drivers who are on the circle have priority.

Driving a car can be dangerous not only because of a direct collision with other vehicles. Injury can also occur due to sudden braking and even standing still due to a rear impact. To avoid damage or minimize it in vehicles, passive protection of the driver and passengers is provided - seat belts, which will be discussed in the article.

Seat belt in traffic rules For passengers For children In the rear seats When you can not fasten your seat belt Penalty for not wearing a seat belt var index=document.getElementsByClassName ("index-post");if (index.length>0) (var contents=index .getElementsByClassName ("contents" );if (contents.length>0) (contents=contents ; if (localStorage.getItem ("hide-contents") === "1") (contents.className+=" hide-text")))

Seat belt in traffic rules The passive protection device looks like a belt encircling the body in the form of the English letter "V". This design dampens the energy of the body in a collision, evenly distributing the braking force, and does not hinder movement in the cabin. The seat belt straps (hereinafter referred to as RB) are made of synthetic, very durable material.

A system for fastening the straps to the vehicle frame is made of a hard alloy capable of withstanding a large load. The RB belt tension system, thanks to a sensitive mechanism, allows you to smoothly tension it and hold back the tension during a sharp jerk.

For passengers

The driver is responsible for the safety of passengers, therefore, before moving off, he must make sure that the restraining devices in the entire cabin are in good condition. He also controls the implementation of the safety rule - the belt should not be thrown on, but fastened.

Possible danger in an accident for the passenger in the front seat:

impact on the side pillar; head injury from the windshield; impact on the dashboard with the chest; contusion of the spine, neck from hitting the seat; departure onto the road through the windshield.

Important! All of the above can bring more than just scratches, cuts and bruises. Such injuries can cause disability or death, so it's worth taking a few seconds to buckle up before riding.

For children

According to the amendments to the traffic rules for 2019 for children under 12 years old, a child's passive protection system must be present in the car. The restraining design takes into account the height and weight of the child in order to be as effective as possible.

Depending on age, the following means of protection are used:

Up to 6 months - infant carrier with fixation straps, located perpendicular to the direction of movement of the vehicle. The baby in the cradle is in a horizontal position. From 6 months to 7 years - car seat for children. For babies up to a year, soft rollers are additionally included in the kit. The back of the chair is fixed at an inclination of 35-40 degrees. Children from 7 to 11 years old - being passengers in the back seat, can be transported with the help of children's structures, as well as without them, but using standard RB.

Important! A passenger under 12 years old can be transported in the seat and in front, but at the same time, a specialized seat is required for him, other options are not allowed.

In the back seats

According to the rules of traffic rules pp. 2.1.2 the driver of a car equipped with RB, must be fastened and make sure that all passengers, including those in the rear seats, comply with the rule.

Unfortunately, not all vehicle models are equipped with restraints in the rear of the cabin. However, where they are present, they are necessarily used, otherwise the traffic police sanctions come into force (more on this below).

In the event of a possible collision, an unbelted person sitting in the rear not only runs the risk of injury, but can also inadvertently harm other passengers. It can be thrown onto people sitting in front and to the side with very deplorable consequences for everyone in the cabin.

When you can not buckle up

Today, after the revision of the SDA in December 2018, there are no exceptions for citizens in the issue of the use of the Republic of Belarus. Everyone is required to buckle up in a car, even drivers of special vehicles.

A situation where a fine for breaking the rules can be challenged is a malfunction of the restraining device was discovered on the way, and the driver moves to the nearest car service to fix the problem. A penalty for a violation of the rules by a rear seat passenger is not eligible if the design of the car does not provide for this measure of protection.

Did you know? The world's first safety harness was invented for a coach driver in 1885 by an American, Edward Claghorn.

Fine for not wearing a seat belt

According to the legislation of the Russian Federation, penalties are provided for non-compliance with the requirements of traffic rules.

Monetary fines are imposed for the following violations:

lack of a belt for the driver, passenger - 1 thousand rubles. ; absence of a child protection system - 3 thousand rubles, while for legal entities the amount increases to 100 thousand rubles, for officials - up to 25.

To buckle up in a car means to ensure your own safety, to show awareness in relation to other passengers. A seemingly simple protection system, according to world statistics, saves lives in 80 cases out of 100.

According to paragraph 2.1.2 of the traffic rules, the driver of the vehicle, as well as its passengers, must be compulsorily fastened with safety belts. This requirement is dictated by security conditions, and is mandatory for execution. Let's try to figure out what role these belts play?

To answer this question, we need to turn to the law of inertia. It says that any body can move uniformly until it is affected by another body. During an accident, there is a sharp change in the speed of the car and the trajectory of its movement. At the same time, all objects in his cabin, including passengers and the driver, continue to move at the same speed and in the same direction. This will continue until they collide with the windshield. Most often, such a blow falls on the head. Even with a minimum speed of 60 km / h, its strength will be 3000 kilograms. It is unlikely that the passenger's forehead will remain intact. But if it remains, then the cervical vertebrae will certainly not do well. At higher speeds, a blow to the windshield will be fatal. To prevent this from happening, be sure to fasten your seat belts.

It is clear that a person wearing a seat belt will also suffer in an accident. But in this case, the load on his body will not exceed the permissible limits. The person will remain in place, and will not fly out through the windshield. In extreme cases, bruises and abrasions will appear on his body, and nothing more. The main thing is that he stays alive. In addition, together with seat belts, pillows will also work, which minimize the load on the cervical vertebrae. The belt will stop the movement of the body, and the pillow will stop the movement of the head. If the passenger is not fastened, then his head will rest against the airbag, and the body will continue to move forward. As a result, a whiplash injury to the spine will be obtained, which will lead to death.

Some drivers do not fasten their seat belts, explaining this by the fact that in an accident a fire may start, and it will not be possible to quickly unfasten the belt. Accordingly, you can simply not have time to leave the flaming car. But in reality, everything looks different. Even if we assume that the car caught fire, the fire can penetrate into the cabin only after 2-3 minutes. This time is enough to unfasten the belt and get out. You can burn alive only if you are squeezed inside the car with pieces of twisted iron. But then you won't care if you're wearing your seatbelt or not.

According to statistics, out of a hundred accidents, only two end in a fire. So think about how justified your fear is, and what is the reality of burning in a car? The probability of this is negligible, but the risk of breaking the spine, being not fastened, is quite real. So no need to rely on chance. The safety rules are written in blood and should therefore be followed. Even if you are absolutely sure of yourself, this does not mean that an accident will not happen. The road is full of inexperienced drivers who can lose control and become the culprits of an accident. And if you are not wearing a seatbelt, you can get seriously injured. If you hit the rear of the car, you can seriously damage your face on the steering wheel, and even lose your teeth. To correct the situation, you will then have to pay a tidy sum at the dentist. And all you had to do was fasten your seatbelt. So it turns out that the requirements of traffic police officers regarding clause 2.1.2 of the traffic rules are quite fair. So, if you didn't buckle up and you got a ticket, pray to God that this is how it ended.

Remember your first day at driving school? Clumsy attempts to start on a flyover and not stall, to drive into your pocket and not knock down the cones ... While you are studying, it seems that the most difficult thing is to pass the exam in the traffic police. But having received the coveted driver's license and driving into the city for the first time on your own, you understand: the difficulties are just beginning.

Every year, more than a million novice drivers set off for free-floating on Russian roads. For those who are taking their first steps into the automotive world, we have collected useful tips from more experienced steering wheel and pedal comrades.

Do's and Don'ts for New Drivers

Let's start with legal nuances: there are special requirements and restrictions for drivers with little experience on the roads. And we are not talking about the cost of insurance increased by 70–80% - you will learn about increasing coefficients when you first apply for an OSAGO policy. There are surprises for beginners in the Rules of the Road themselves.

Sign "Beginner driver"

“The Kettle should be visible from afar,” the legislators reasoned, obliging all drivers with less than 2 years of experience to place a special sticker on their car. And this is by no means the letter “U” in a triangle, known from the training machines of driving schools and the song “Spleen”. Beginners must mark their personal transport with the “Beginner Driver” sign - a yellow square 15 × 15 cm with a black exclamation point in the middle. The fine for his absence from the car is 500 rubles.

It is not worth considering such mandatory “labeling” offensive or shameful. The sticker works in the interests of the novice driver himself: the people around him become more indulgent towards his inept actions on the road, which means that there will be less irritated horn signals in the back.

Towing

A bunch of two cars looks spectacular (professionalism, mutual assistance on the road and other beautiful associations), but do not rush to get the cable if you see a broken car. According to the traffic rules, with a driving experience of less than 2 years, you cannot tow a car, since this requires certain skills and experience. So, with little experience, you will not be able to help out a friend who is left without gasoline by dragging his car to a gas station. However, there is an easier way: take a canister and bring fuel from a gas station.

But a novice driver can drive a towed car quite legally. Which is a little strange, because it's much more difficult than towing someone. But the correct towing technique is the topic of a separate article.

Transportation of people

Many pass the exam for several categories at once: the passenger "B" is often combined with the cargo "C" or the motorcycle "A". The latter for beginners has a restriction on the transportation of people: you cannot put a passenger on a motorcycle without having two years of driving experience on two-wheeled vehicles. This also applies to mopeds, although 2 years of experience in any driver category is suitable for them.


Driving schools often teach you how to pass an exam, not how to drive. Driving in busy traffic has little to do with cutting circles on a race track or a predetermined test route. Having got into real traffic after greenhouse conditions, it is not surprising to get confused. Here are 5 tips to make your life easier:

1. Call on a friend for help. Ask an experienced driver you know to ride with you as a passenger, pay attention to mistakes and give advice from the outside. In many countries, this is a prerequisite for beginners behind the wheel: in the first months, you can only drive with an assistant. In Russia, there is no such requirement, but this is a reasonable practice that should be adopted. The main thing is to take as a companion the most phlegmatic friend who will not emotionally react to your mistakes. A good driver and a good teacher are different roles.

2. Avoid traffic. Driving in heavy traffic at low speed only seems harmless. In fact, it is very exhausting for drivers and often leads to minor but annoying accidents. While you have little experience, plan your route and departure time so that you move on free roads. Yandex service. Cork to help you.

3. Forget your smartphone. Driving a mobile phone is no less dangerous than alcohol: being distracted for just a couple of seconds, you can completely “fall out” of the traffic situation. By the way, traffic rules forbid the driver not to talk by phone and enjoy them - including writing messages, scrolling through social networks and taking pictures (selfies while driving will have to be taken in the parking lot). It is just possible to talk on the phone while driving, but only using a wireless hands free system.

Modern smartphones have a Do Not Disturb function with automatic activation when driving a car - set up and use it so that calls and notifications do not distract from driving.


4. Always follow traffic rules. With the words that the Rules are written in blood, classes begin in every driving school. And it's not just a boring stamp. An average of 45 people die on Russian roads every day; neglect of traffic rules is one of the reasons for this.

Do not exceed the speed limit, do not try to pass through a yellow traffic light, do not make dangerous overtaking and do not make turns in areas with poor visibility. Let in the stream you can be a white crow - but a whole white crow that has safely reached its nest.

5. Learn theory. Do not listen to fairy tales that you can learn to drive only by practice - long experience is far from a synonym for good driving skills. The basis of confident control of the machine is the understanding of its operation, the forces acting on it and the consideration of external factors. Any extreme driving lessons begin with theory, and only then it is worked out in practice. Be interested, collect and analyze information - this will significantly speed up your driving progress.

Materiel. Vehicle device

The times when the car owner was also a mechanic are long gone. Today, many drivers can safely be called operators: they have a vague idea of ​​\u200b\u200bthe operation of the machine. But it is necessary to know at least in general terms how everything works in a car. You can compare this with knowing about your own body: you don’t have to be a doctor, but knowing the basic things about the role of internal organs is very useful.


Get into the habit of giving your car a quick look before you leave. Moreover, it is directly prescribed by the traffic rules:

2.3. The driver of the vehicle must:

2.3.1. Before leaving, check and ensure that the vehicle is in good technical condition on the way.

Pay attention to the condition of the wheels and tire pressure - learn how to measure and adjust it correctly. Watch carefully

Good afternoon. In today's post I will tell you why you need to fasten your seat belts when driving a car. On video examples, I will show what will happen in an accident with those in the car in the case of fastened seat belts, without seat belts, and separately consider the option why the airbags do not work if the seat belt is not fastened.

Short answer.

If, during an accident, you are in the car without being fastened with a seat belt, you, by inertia, will continue to move until you hit the glass or the seat. In a collision at a speed of 60 km / h, a passenger weighing 75 kg will receive a blow with a force of about 3000 kg. Whether the head and neck will withstand it is a big question.

A little physics.

From the point of view of Newtonian physics, one of the main characteristics of any body is its mass.

Mass mainly determines inertia, or how quickly an object under the influence of a force will accelerate or slow down.

By the way, it is inertia that explains our article about the safest car.

What happens in an accident?

The car, having received a blow, changes the speed and direction of movement, and all unsecured objects in the cabin, whether they are unfastened passengers or a fire extinguisher on the rear shelf, tend to continue moving along the original trajectory. They do this until something stops them….

Here is an example of how salon utensils behave in an accident:

Why is it important to wear a seat belt every time you drive?

This is best understood by watching this video:

As you saw, the mannequins, not wearing seat belts, went on a free flight around the cabin, smashed the windshield with their heads, and according to the readings of the sensors, they experienced overloads incompatible with life. If there were living people in the car, at best they would go to intensive care.

Note that the standard crash test is carried out at a speed of 64 km / h, and in life, many accidents occur at high speeds.

Now consider the same car, but mannequins fastened with standard seat belts:

As you can see, after the accident, the dummies remained in their places, and the load did not exceed the maximum allowable. Obviously, if there were people in the cabin for the mannequins, they would get bruises from the belt and abrasions from small objects, but in general, they would not suffer much.

The third video is the same car (Priora is the same VAZ 2110), but equipped with airbags:

As you can see, the load on the mannequins. Decreased even more.

This happens, for the reason that the moment of opening the pillows is selected according to the impact force in such a way as to minimize the load on the neck and spine, i.e. the belt has already rested against the chest, and the head is still moving forward, at this very moment you will receive a blow from the pillow in the face.

Why does the airbag not deploy if the seat belt is not fastened?

The reason is simple. Studies have been carried out and it has been found that passengers who are not wearing a seat belt, deployed airbags, injure more than flying with their head into the windshield.

There is a so-called. whiplash injury of the spine. In the extreme case of a whiplash injury, death occurs instantly and it is impossible to help a person with any resuscitation measures - the spine is broken in the cervical region. It is interesting that in this case visually a person may not have damage.

Popular misconceptions about the seat belt.

I do not fasten my seat belt, because in a fire accident, I will not be able to unfasten it and I will burn alive.

That's bullshit! Even if the car's fuel pump continues to work (although in 95 percent of cases after the engine is turned off, it turns off), until the burning starts in the cabin, you will have 1.5-2 minutes.

During this time, you can unfasten the belt and even throw it over your head and get out.

As a rule, they burn alive when they are pinched in a mangled car, in which case it doesn’t matter if you were wearing a seat belt or not.

According to statistics, fire accidents account for less than 2 percent. Those. in just 2 cases out of 100, your fear is justified, and in 98 cases, if you do not fasten your seat belt, you risk death or serious injury.

Here is a video of an accident with a driver burned alive (the driver, if he had not been pinched, had about a minute and a half to get out of the passenger compartment, believe me, he would have had time to unfasten his belt). The attention of the video is shocking:

I don't wear a seat belt because if the car rolls over, I can be thrown out of the passenger compartment and get less injuries.

According to statistics, rollover accidents account for about 6 percent of the total number of accidents, and accidents with multiple rollovers are even less - 2 percent.

The probability of flying out of the cabin and not getting injured is minimal! In 2008, my classmate died in such an accident - she flew out of the passenger compartment, and she was crushed by the car in which she was. This way it will be more likely than to fly out and remain without injuries.

Here is a video example of a crash test with an SUV rollover with unbelted passengers:

Here is a shocking video about the consequences of “flying out” of the passenger compartment, even without tipping over (no one in the VAZ 2110 was wearing seat belts):

I do not fasten my seat belt, because I am confident in my abilities and I will not have an accident. Or I have confidence in the driver and I don't fasten my seatbelt because I want to show that I respect him….

This is complete nonsense. Now the situation on the roads is like this - you are not so into you.

My friend, standing in a traffic jam on the ring road, got in the ass from a truck, and after a collision with a bump stop, he left his teeth! If he had been wearing a seat belt, there would have been no consequences for his health in that accident. It's not about respect, it's about your safety!

Conclusion.

I hope that after reading my article, viewing my examples, you understand why you need to fasten seat belts when driving a car. And you will agree that the requirement of traffic rules for the mandatory use of belts and the fine for ignoring this rule are very reasonable.

Do not drive, think with your head and May you never experience the deployment of seat belts and airbags.
