Alcohol intoxication is one of the most common causes An accident in Russia, so every driver should know what the permissible norm of alcohol in exhaled air and in the blood of a person driving a vehicle was established in 2018-2019.
Why do we say that there is an acceptable minimum threshold if we know " Golden Rule» – planning to drive, do not drink a gram of alcohol! It's simple - 0.16 mg / l is the standard error of the instruments used today by traffic police officers of Russia. When recalculated for the content of alcohol in the blood, we just get an indicator of 0.35 ppm.
The concept of "allowable amount of alcohol drunk" does not exist!
Each organism is individual and reacts to products that contain alcohol in its own way. For someone, 50 grams or even less is enough for the well-known sensation of light dizziness to appear. But, even the absence of obvious symptoms does not mean that a person is sober.
Inhibition of reactions of the central nervous system and dullness of attention under the influence of small doses of alcohol occurs much earlier than the obvious symptoms of intoxication appear.
That is why you should never be guided by the correspondence tables posted on the net, stating that the breathalyzer will not feel if you drink 40 grams of vodka or 300 grams of beer. Moreover, such a state can occur not only with the use of alcoholic beverages, but also with the ingestion of a number of other substances used in pharmacology and medicine.
Therefore, it is important for every novice motorist to know in which case serious troubles await him, how to avoid them, and, most importantly, how to act when a charge has already been filed.
Officially, in 2018-2019, the permissible norm of alcohol in exhaled air or in blood is checked.
Option 1 - the driver is tested for the presence of alcohol in the body using a breathalyzer ( special device, which determines the percentage of alcohol vapor in the exhaled air).
Option 2 - the driver is offered to take a blood test (from a vein) at the nearest medical facility. As a rule, blood is taken for analysis in cases where the driver is physically unable to pass faster test described in the first version.
To date, the minimum threshold is set at:
Important! Refusal to undergo an alcohol testing procedure, according to the norm of the law, is equated to the fact that you are in a state of intoxication.
Now you know what the permissible blood alcohol level is set for drivers of all vehicles in 2018-2019 and what it depends on. Therefore, the first thing to do if traffic police officers require passing the test is:
Moreover, the driver has the right to see that the tip for the device is disposable and new. Ideally, a traffic police officer should not touch the unpacked tip of the breathalyzer.
A result of 0.16 ppm means the driver is sober!
The Kolesa.ru website has an excellent memo for the driver, following which you will not find yourself in a difficult situation.
If, despite your complete confidence in your sobriety, the device showed more than 0.16 ppm, the main thing is not to sign consent with the results obtained, state your disagreement in detail on paper and go to the nearest medical facility where you can undergo an examination as soon as possible. The blood test will more weight during the trial.
Among the drivers there are a lot of the most different stories about how the breathalyzer showed more than 0.16 ppm, although the person did not touch alcohol at all that day. Is it possible?
Experts who have studied this issue unanimously declare that a variety of products can give an excess of the norm:
But, it's all very individual. We offer you to watch one of the videos, which tests whether the permissible norm of alcohol in the exhaled air is exceeded after consuming a number of the products listed above, and also tells why in 2018-2019 they will believe more in the indicators of ppm in the driver's blood.
No matter what caused increased rates(especially if they are confirmed by a blood test), the driver, as well as the owner of the car, who transferred control to a person in a state of intoxication, are responsible:
When discussing how many ppm is allowed in a driver's blood in 2018 and 2019, few people think that this letter of the law is the result of numerous accidents that claimed many lives.
Of course, it’s unpleasant if you are accused of drunkenness when stopping at a traffic police post, but everything is much more serious if an accident occurs due to the fault of a drunk driver. There are completely different articles of the Criminal Code of the Russian Federation and the punishment can be much more serious, namely:
It is still possible to regain the right to drive a vehicle after the court finds guilty under this article.
At the end of the period of deprivation of rights, the convicted person must:
We also suggest listening to the advice of lawyers who will tell you how to behave if you were stopped at a traffic police post and what to do if the breathalyzer gave a positive result:
Every year in Russian Federation an increase in the number of motorists driving in a state of alcohol intoxication. Unfortunately, most of these violators do not even think about the public danger their actions carry at such a moment.
Every driver knows that driving after drinking alcohol is prohibited. However, in some cases, the temptation to break such a law and drive a car while intoxicated is very strong.
Even if a motorist drank a little on a holiday and is not afraid to drive, he should know what is the permissible rate of alcohol when driving.
After the zero ppm law was lifted, many motorists relaxed. They felt that it was now permissible to drink alcohol in small quantities. In fact, such a law was withdrawn due to the inability to provide all drivers with unique body properties with certificates about this. In addition, the legislator considered it inappropriate to fine a motorist for drinking kefir or drinking some juice.
However, this does not mean at all that it is now possible to consume alcohol-containing drinks uncontrollably and then drive.
Before you start driving vehicle, the motorist must independently learn about the permissible ppm. After all we are talking not only about the possibility of receiving a large fine and deprivation of a driver's license. Often, drunk driving ends in the death of innocent people who just happened to be in the wrong place at the wrong time.
Many drivers, when stopped for checking by the traffic police, decide to deceive the breathalyzer. In fact, the breathalyzer is precision instrument which can neither be deceived nor outmaneuvered.
Therefore, it is best not to tempt fate, because for this additional measures of responsibility can be applied to the violator.
Two methods are used to determine the amount of alcohol in a person's blood:
In both of these options, studies are measured per mille.
Ppm is a specific quantitative parameter that indicates the content of ethyl alcohol in a liquid medium (in this case, in human blood). This indicator is designed to determine the stage of intoxication.
During the analysis, specialists or traffic police officers find out how many milligrams of alcohol are contained in one hundred milliliters of the blood of the person being tested. When using a breathalyzer, 1 ppm is 0.045 milligrams of ethyl alcohol in human blood.
This value is recognized as the base value in all methods for determining the amount of ethyl alcohol in the human body. The more ppm the device shows, the stronger the intoxication of the tested person.
Previously, the law “on zero ppm” was in force in the Russian Federation, according to which every motorist was held liable if the device found at least 0.01 ppm in the analysis of whose exhalation.
After several years of research, this normative legal act was declared invalid, since such a norm does not correspond to the state of the human body. In addition, one cannot exclude the possibility of an error in the instrument, which measures the amount of ethyl alcohol in human blood.
After conducting research, it was found that the content of alcohol in human blood may be due to the intake medicines, which include this ingredient (corvalol, motherwort).
In addition, ppm will be detected in the driver's blood, even if he consumed drinks containing fermentation products, such as kvass or kefir. In some human diseases, the breathalyzer can also detect an excess of the permissible ppm rate.
A motorist who wants to drive after drinking alcohol should remember that ethyl alcohol vapors disappear from all human bodies over a different period of time.
Therefore, you should not be guided only by generally accepted medical indicators, which are averaged. As a result, a motorist who drank alcohol a few hours ago can be prosecuted for drunk driving.
After all changes were made to the legislation, the allowable ppm rate was increased. When checking with a breathalyzer, it is 0.16 ppm, and during a medical examination (blood is checked, not exhaled air) - 0.35.
The traffic police officer, who established the fact of exceeding the permissible norm per mille, brings the motorist to administrative responsibility.
If a motorist refuses to undergo a medical examination, the traffic police officer has the right to hold him accountable as for the primary violation of the law on driving while intoxicated.
Car owners should also be aware that if they entrusted the management of transport to a person in a state of intoxication, a fine of 30 thousand rubles will also be taken from him and rights for up to 2 years will be taken away. You cannot trust another person to drive your car, especially someone who is intoxicated.
A motorist who wants to relax in the evening with a bottle of beer or other alcoholic drink should be aware of how many ppm are contained in a particular alcohol-containing drink. The most popular alcohol consumed outside holidays- beer.
The permissibility of drinking beer before driving directly depends on the degrees of this drink. To get acquainted with this information, just read the information on the bottle label.
Of particular importance is the weight of a person. For example, a motorist weighing 60 kilograms, who drank half a liter of 6 percent beer and got behind the wheel, will be held liable, as the breathalyzer will show a value of 1.07 ppm.
Over time, the amount of alcohol in a person's blood gradually decreases. Therefore, every motorist who has drunk an alcoholic drink should know how long it will take him to get behind the wheel.
Average medical statistics shows that within one hour from the blood of a woman leaves from 0.085 to 0.1 ppm. During the same period of time, from 0.1 to 0.15 ppm of alcohol leaves the blood of a man.
In practice, the rate of removal of ethyl alcohol vapor from the human body depends on many other factors, in particular, on the individual characteristics of a person. On average, one bottle of beer vanishes within 6 hours.
Even though a person may feel clear and sober, this condition does not indicate that the vapors of ethyl alcohol have completely disappeared from his body and the amount per mille has begun to correspond to the permissible minimum.
If a motorist drank an alcoholic drink, and then he had to drive his car, he must adhere to certain rules of conduct. To avoid maximum liability for such an offense, the driver must comply with the following rules:
There are several conditions under which ethyl alcohol vapor disappears from alcohol much faster than usual:
The legislator advocates that the responsibility for driving while intoxicated will only become tougher. This is due to the constant increase in the number of accidents caused by drunk drivers. Unfortunately, most of these accidents end in death.
Therefore, in the near future we should expect harsher penalties for driving while intoxicated.
Don't risk your driver's license and drive drunk. It is always possible to find a sober driver or use public transport.
Perhaps the greatest interest among drivers is kvass. Like any other fermentation product, this drink contains a small amount of alcohol. However, even such an amount of alcohol will be enough for the breathalyzer to give an indicator of 0.4 ppm after one bottle, which is already a violation of the rules. traffic.
Therefore, even after drinking such a drink as kvass, you can’t drive.
If a motorist really wants to drink beer, he can limit himself to non-alcoholic beer. This drink gives only 0.2 ppm, so you can drink it in small quantities.
With weak beer, vodka and wine, you should be careful. These alcoholic drinks give a very high ppm.
So, for example, a driver weighing 80 kilograms can safely drink in the evening (provided that he sets off on the road only the next morning):
A woman can drink 20 percent less of such alcohol.
The number of drinks is much less than everyone is usually used to drinking. Therefore, if the road is expected the next day, it is best to completely abandon the use of alcoholic beverages.
Permissible rate alcohol driving in ppm 2017, law 0.16. How to avoid exceeding the norm, what it threatens and what affects the alcohol content.
Alcohol affects the human brain. In order to reduce the number of deaths on the roads due to drunk drivers, a law on “zero ppm” was passed.
But due to the errors of breathalyzers and physiological characteristics organism, in 2013 increased the rate from zero ppm to 0.16 in exhaled air and 0.35 in blood. These rules apply to drivers of all motor vehicles, including mopeds and scooters.
A ppm is one thousandth of something. The percentage is one hundredth. The phrase “blood alcohol content of 0.2 ppm” means that 0.02% of the blood taken for analysis is alcohol. This is 0.09 mg per 1 liter of blood.
The same applies to the exhaled air. The breathalyzer measures the volume of gas and what part of it is alcohol vapor, and expresses the value in ppm.
The higher this value, the more ethyl alcohol has entered the human body, the stronger the consequences. For driving, the effect of ethanol on the brain is important. Driving while drinking alcohol is dangerous.
Initially in adopted law was the number 0. But ethanol itself produces human body, in some diseases, the proportion of alcohol in the exhaled air or in the blood may be higher.
This feature does not affect the ability to think clearly and evaluate the traffic situation. Meters are also failing. Therefore, we decided to increase the value for the breathalyzer to 0.16.
The permissible alcohol limit for driving in ppm in 2016 is identical to 2015 and 2017.
If the breathalyzer recorded an amount of alcohol of 0.17 or more, then, according to the law, problems await you:
If you took alcohol the day before, residues that exceed the norm may be found in the blood and exhaled air the next morning.
Excretion of alcohol from the body depends on age, sex, weight, general condition health, the amount drunk, the condition of the liver and kidneys. To find out if you can drive, buy a household breathalyzer.
True, if it is not of high quality or its batteries are dead or its service life has expired, then the results will differ from the professional ones used by inspectors.
There is a list of foods that briefly increase the amount of alcohol in the blood. If you breathe into the breathalyzer immediately after or within 5-10 minutes after their use, it will record the excess of the permissible norm:
The permissible rate of alcohol while driving in ppm 2017 is law 0.16. If you ate or drank something from the list above, then most likely you will meet the norm. In any case, after 20-30 minutes the breathalyzer will show 0.
Therefore, if you are sure that you are right, insist on a re-examination after a while. Also, a medical examination can confirm that you did not drink alcohol.
If you are sure that you did not drink alcohol-containing drinks, and the breathalyzer shows an excess of the norm, require a medical examination.
The inspectors can insist on this if they see external signs intoxication, while the instruments show the norm. In this case, your refusal will mean an admission of guilt and will entail punishment.
Listen carefully to what the inspector says and read what you sign. You can refuse to be examined by the traffic police, but you cannot refuse a medical one.
Some inspectors deliberately confuse drivers who are under stress from an unpleasant situation, and “bring” them to a fine and.
If you hear or see the word "medical", in no case refuse. Ask for clarification and clarification of what is meant.
Important points to keep in mind:
The permissible rate of alcohol while driving in ppm 2017, the law is 0.16. If, upon arrival at the medical center, the breathalyzer shows a value less, then these readings will be entered into the protocol, the inspector will take you back.
In any case, you will be required to take a urine test. This takes place in the toilet, which is always standing next to the mobile honey station. examinations.
Doctors must check urine temperature and ph. If it is established that this is someone else's analysis or it is diluted with water, this will be equated with a refusal.
If a sufficient amount is not collected for analysis within 30 minutes, then a blood test is taken.
An important point: when treating the skin, doctors are required to use an alcohol-free solution! The test tubes are sent to the laboratory, after 10-13 days the answer will come. Until this moment, it is forbidden to drive a vehicle.
The adoption of the law on "zero ppm" has reduced the number of accidents with drunk drivers. Statistics for 2016 says that a total of 13,100 people died due to the fault of car drivers.
Of this number, 3789 died due to the fault of drivers who were in a state of intoxication. This is 17% more than in 2015, although total"alcoholic" accidents and decreased by 1%. The problem is very acute and does not seem to be solved by severe fines and punishments.
Per mille is a specific measure of magnitude, denoting 1/1000 share and 1/10 percent. Many have come across such indicators when it comes to measuring alcohol in the blood. But few people know that officially the value is used to measure the salinity level of the water or the slope of the railway tracks. As it may seem at first glance, the presence of 1 ppm of alcohol in the blood is mere trifles. As practice shows, this value is quite enough to determine that the driver is under the influence of alcohol. What ppm is allowed in 2018? Find out these details and more in this article.
Alcohol while driving is one of the most pressing problems in Russia, so law enforcement officers are trying to fight this vice as hard as possible. The tightening of sanctions, the introduction of fines, criminal punishment are just a few methods of dealing with persistent violators of the order. But Russian people it is difficult to scare something, which leads to the fact that there are more and more accidents on the roads due to the fault of drunk drivers.
To begin with, today there are two ways to measure the level of alcohol in the blood:
1) Determination of alcohol in the air, which the driver exhales into a special tube. The amount of alcohol should not exceed 0.16 ml per liter = 0.16 ppm;
2) Determining the amount of alcohol in the blood of the driver. For analysis, the driver, who is suspected of driving while intoxicated, is taken to a medical facility. Blood for analysis is taken from a vein. The allowable limit is 0.35 ml per liter = 0.35 ppm.
The second method is more objective, since it is this indicator that is recorded in the protocol and will serve as evidence of the charge in the future. It should be remembered that even for such an accurate analysis, there is an error that is 0.05 ppm. Current legal regulations take into account the permissible error of the device used, as well as the use of products containing alcohol. Also in the presence of diseases, for example, diabetes or pathologies digestive system, endogenous alcohols can accumulate in the body, which affect the indicators of the presence of ppm in the blood.
The permissible ppm rate for drivers in 2017-2018 is significantly different from the one that was established from 2010 to 2015. During this period, Russian legislation provided for only 100% zero. Thus, the amount of alcohol in the blood and exhaled air was strictly not allowed. To date, such a law has become invalid due to several circumstances.
First of all, certain foods and drinks that at first glance do not contain alcohol or alcohol impurities were called into question. In fact, numerous tests carried out on various products have shown the presence of a hundredth of a ppm of special devices. These products include:
- nonalcoholic beer
- chocolate candies
- kvass
- dairy products
- unrefrigerated juices
- black bread with some types of cereals
- tobacco products
– oranges
- refreshing mouthwash
- Overripe bananas.
It may seem strange, but all of the above products contain a minimum amount of alcohol, which disappears after a certain time. For example, a driver who drank a glass of kefir, curdled milk or kvass in the morning had hundredths or tenths of a ppm in his blood. Such situations were not isolated, and often led not only to fines, but also to deprivation driving license for up to two years. This fact provoked controversy among Russians, leading to the adoption of a new law to abolish zero ppm in July 2013.
Considering the data Common European System traffic rules, the permissible rate of alcohol in the blood is not more than 0.5 ppm. But this rule is followed in all countries, where in some of them the allowable rates range from 0.00% to 0.8%. For example, in Moldova, the Czech Republic, Hungary, Armenia and Slovakia, the permissible level of ppm in the blood is 0%. In these countries, for exceeding the permissible levels of alcohol in the blood, you can say goodbye to a driver's license for a period of 3 to 5 years. In Romania, for example, a driver with the presence of alcohol in the blood can be imprisoned for up to 5 years.
More “modern” countries believe that if you drink a glass of beer or red wine before a trip, this will not affect your driving skills in any way. Nevertheless, the permissible rate of alcohol in the blood is up to 0.8% ppm. Such laws apply in the UK, Malta and Liechtenstein. However, according to the statistics of fines in these countries, such loyalty of the representatives of the law to drivers shows the opposite effect. For example, in the UK, if a driver exceeds the legal limit for alcohol in the blood, a driver can receive a fine of 5,000 euros, lose their driver's license for one year, or even end up in jail for up to 1 year. Such penalties apply if driving under the influence of alcohol did not provoke serious violations on the road. If, due to the fault of a drunk driver, an accident occurred with injuries or deaths, the culprit will face imprisonment for up to 14 years and huge fines.
The zero ppm rule is in effect in Japan, Equatorial Guinea, the United United Arab Emirates, Libya, Cuba, Iran, Brazil and a number of other countries. A fine for alcohol while driving in Japan is provided not only for drunk drivers, but also for their passengers, who face about $ 3,000. The driver will have to pay a minimum of $8,700, and you can also go to jail for 5 years. A bar that sells alcohol to a driver, knowing that he is driving, may lose his license.
On this moment It became known that the Ministry of Internal Affairs of Russia is considering a new bill, according to which it will be possible to increase the possible concentration of alcohol in the blood of a driver of a vehicle to 0.3 grams or more.
The introduction of the maximum amount of alcohol in the blood while driving is one of the main means of regulating road safety by the state.
The unit of measure for alcohol intoxication is ppm.- the ratio of a gram of alcohol per liter of blood.
The maximum ppm threshold while driving differs in different countries. For example, in Canada, ppm is 0.8, which allows you to drink a glass of beer before the trip..
What is the legal limit for alcohol while driving in Russia? And what happens if it is violated? Let's figure it out.
For three years, from 2010 to 2013, the allowable rate was “zero” ppm, which completely excluded the possibility of a dispute with traffic police inspectors. However, this rule had many shortcomings. Eating many foods shifts the blood alcohol level above zero - chocolate and bakery products, kefir and kvass, juices, yogurts and too ripe bananas. Not to mention non-alcoholic beer or many medicines.
In 2013, the effect of "zero" ppm was canceled. Now driving a car is allowed if the breathalyzer showed when exhaling no more than 0.16 mg per liter of air. This is the new measurable threshold of intoxication. But ppm is a value that calculates the alcohol content in the blood, and not in the air.
0.1 ppm, contrary to popular belief, is not equal to 1 mg / l. To calculate it, a formula is used in which there are exactly 0.045 mg / l of alcohol in 0.1 ppm. After calculations, we find that the allowable maximum ppm in the current year is approximately 0.35.
The new norm minimized the measurement error of the breathalyzer. How to determine the approximate content of ppm in the blood after drinking alcoholic beverages?
It is not difficult to exceed the permissible norm of alcohol while driving. 1 ppm is already a serious intoxication, which is achieved after drinking a whole bottle of 0.5 liter vodka strong man weighing 70-75 kg. The maximum allowable rate is 5 or 6 ppm units. This is already a lethal dose.
100 grams of vodka in theory give 0.55 ppm, and a bottle of beer with a capacity of 0.5 liters - 0.32. In practice, when checking on a breathalyzer, there may be a completely different result. The device can overestimate ppm (for example, with alcohol vapor in the lungs after sobering up) or reduce it. To avoid this ambiguity in the definition of intoxication, the critical value ppm and has been increased to 0.35.
It is difficult to calculate the content per mille in the body on your own. For this, there are ready-made tables in which a drunk glass of vodka with a capacity of 100 grams is taken as one dose. The results are also quite arbitrary, but sometimes they can be useful.
We offer 2 tables with ready-made calculations - separately for men and women.
Weight, kg | Number of doses taken | ||||
1 | 2 | 3 | 4 | 5 | |
45 | 0,43 | 0,87 | 1,30 | 1,74 | 2,17 |

110 | 0,20 | 0,41 | 0,61 | 0,82 | 1,01 |
To determine the time during which it is better not to get caught by traffic police inspectors after drinking alcohol, it is necessary to take into account many factors, including the rate of absorption of alcohol, the time of its removal from the body and body weight. The highest blood alcohol content is reached 30 minutes to 2 hours after consumption, depending on the type of drink and the availability of a quality snack.
Many drivers are interested in knowing how long it takes alcohol to completely disappear from the body. General rule here it is - it is absolutely impossible to drink alcohol before an imminent planned trip. If there is still a whole day left before driving the car, you can drink freely. The rules are not ironclad, but quite effective.
We propose to consider a table that shows how long various alcoholic beverages are excreted from the human body. It should only be borne in mind that these data are seriously affected by a person's weight, gender and state of health.
Type of drink, alcohol content in % |
Quantity (ml) |
Time during which alcohol vapor can be detected in exhaled air (hour) |
Vodka (40) | 50 | 1,0-1,5 |
Vodka (40) | 100 | 3,0-3,5 |

Beer (6) | 500 | 20-45 minutes |
AT general case for a healthy male weighing 80 kg, the weathering time for alcohol will be as follows:
The alcohol withdrawal time for people with a different weight is easily calculated using a proportion. But do not forget that the error of devices for checking the state of intoxication is from 0.1 to 0.16 ppm. For reinsurance, it is better to add at least an hour to the given data.
In 2019, the punishment for drunk driving is quite severe:
AT State Duma there is constant talk of tougher penalties for drunk driving. It is possible that in the future the amount of fines will increase significantly. By the way, the transfer of the right to drive a vehicle to a drunk person is punished in the same way as self-driving while drunk.
In addition to the fact that drinking alcohol and driving a car should be as far apart as possible, less obvious rules should be followed:
How to increase the rate of alcohol withdrawal from the body? good decision there will be a contrast shower, a strong and long sleep, hot baths. Correct, healthy food and long walks in fresh, clean air. Recall that when exhaling air, no more than 0.35 ppm is permissible.
