On this page, you can take an alcohol test online and find out if you can drive, and if not, how long should it take for your blood alcohol level to be normal.
The test is based on a person's physiological data - gender and weight, types of alcoholic beverages and the time that has passed since drinking.
The program automatically calculates the amount of alcohol in drinks, how much a man or woman with a certain weight needs to ensure that the body can cope with alcohol, and according to the time that has passed since drinking - is it possible to drive already, or how much more time is needed, what If the breathalyzer showed the alcohol content is normal.
Why do you need to know the alcohol content before leaving?
It is difficult for a person after drinking strong drinks to determine whether he is really sober or not.
In addition, it is difficult to predict the readings of a breathalyzer, and most likely there will not be such a device at home. Depending on the amount and tolerance of alcohol by a particular person, his condition may be outwardly indistinguishable from sober.
If we do not take into account the state when intoxication is noticeable to the naked eye and the person looks sober, even a small amount of alcohol affects the ability to perceive information - the driver begins to lose measure, he overestimates himself and underestimates the traffic situation.
In addition, the reaction speed slows down in case of unforeseen situations. For example, 100 grams of pure alcohol slows down the reaction rate by 2-4 times. Therefore, even a small amount of alcohol makes the driver dangerous to others.
While driving, the following signs can give out a drunk person behind the wheel: sudden braking, overly self-confident or overly cautious movement, ignoring prohibitory signals, leaving traffic lights late, unnatural trajectories of movement - a combination of such signs can cause the car to stop for a subsequent check of the driver for sobriety.
During communication with the inspector - the smell of alcohol from the mouth, it is difficult for a person to express himself, the pupils do not react to light, a red face, or vice versa - pallor, inadequate condition, difficulty in movement and impaired coordination. One of the listed conditions is enough to receive an offer to be tested for alcohol content in the body.
Passing an alcohol test with breathalyzers
Alcohol testing can be done on site, with mobile devices and in the laboratory.
For a quick test that will allow you to immediately decide on the likelihood of the presence of alcohol in the blood, a breathalyzer is a device that determines the concentration of alcohol in a person's exhaled air.
Breathalyzers are:
- household, for individual self-control;
- special, for more frequent use than household;
- professional, designed for a large number of measurements per day.
Household ones can rarely be used in small businesses to make sure that an employee can be put behind the wheel. This tester is designed for infrequent use. Special ones are more often used at enterprises before the release of drivers on a flight or route, as well as at enterprises where work is carried out with increased danger.
Special testers in some countries are used by the traffic police, may have a certificate that they are a medical product. Such devices are designed for an average of 30-50 applications per day.
Professional breathalyzers are designed for multiple use throughout the day. These tests are most often used by the traffic police to determine the content of ppm in the body, they can be connected to a printer to print out the results of the analysis.
Special and professional testers are periodically verified and calibrated for accuracy
If the inspector offers you to take a test on a breathalyzer, you need to remember that you must first show the device itself and advise on how to pass the test correctly. Everyone can demand to show the license and certificate of the device.
Examination for alcohol content must take place at the place where the vehicle stops, the presence of two witnesses is a prerequisite. If the alcohol level is less than 0.2 ppm, then the driver is no longer detained. If more, then a protocol is drawn up where the test indicators are indicated.
Upon agreement with the indicators, the driver is released, and the protocol and other related documents are submitted to the court. If the person who was tested does not agree with the results, a second test is carried out in the laboratory (first-aid post).
The driver has the right to refuse to undergo a breathalyzer test, in which case the examination will take place in the laboratory.
Only a qualified doctor has the right to conduct an examination in a medical institution
The examination includes checking the pulse, pressure, pupil reaction to light, psychophysiological check. It is carried out twice, the second time - after 20 minutes after the first.
Biological samples are collected - blood, urine and saliva are taken in two copies - one is used immediately for research, the second sample is stored for 90 days in case the driver during the trial wants to re-examine. The results of the survey are issued in triplicate - one for the driver, one for the inspector and one for the doctor.
If today you need to be driving, and the day before you drank alcohol, then you need to make sure that there is no alcohol left in the body. If the number of ppm cannot be checked with a breathalyzer before departure, we suggest using an online test. It does not require a store purchase, periodic calibrations and expiration dates.
Specify the minimum required parameters in the test, and the program will calculate the amount of ppm and how much more time alcohol needs to make your indicators in order.
Holidays are coming soon, which means that most of our country will drink alcohol. Light: - beer, champagne, wine or heavy: - vodka, whiskey, brandy. But it often happens that you have to drive in the morning, well, or even on this day - in the evening! But this question torments me - have these strong drinks disappeared from the body? And how long before they do this? You know, the situation here is not unambiguous, you need to take into account gender, weight, height and, of course, physique. However, in this article I tried to collect all the useful information, there will be both tables and a calculator by which you can easily and quickly calculate the complete “weathering” ...
Today, almost no event or celebration is complete without alcohol. When alcohol enters the body, it is quickly absorbed into the bloodstream and thus spreads throughout the body.
The level of its maximum concentration in the body is observed an hour after ingestion, and then the alcohol begins to gradually disappear.
In general, its excretion is a rather complex process in which most of the internal organs are involved.
Moreover, even after the withdrawal of alcohol from the blood, a high level of its concentration continues to remain in the urine and cerebrospinal fluid. The specific weathering time of alcohol depends on a number of circumstances that must be considered when consuming alcohol.

How long does it take for alcohol to leave the body?
The best way to find out the duration of alcohol withdrawal is the alcohol weathering table. In order to accurately calculate the necessary data, first of all, it is necessary to determine the volume and type of alcohol consumed.
When drinking beer, you need to keep in mind that immediately after taking even one glass, the result of the breathalyzer is higher than after wine. At the same time, the beer is quickly removed from the blood, but it still takes at least eight hours for the final weathering.
Wine with a strength of 12 percent in the amount of seven hundred and fifty grams in most cases contributes to the appearance of severe intoxication.
Complete withdrawal of alcohol from the blood occurs only after twelve hours.
As for vodka, the consumption of three glasses most often leads to severe intoxication.
At the same time, being strong alcohol, vodka first reacts in the stomach, and only then is absorbed into the blood. Therefore, immediately after the adoption, the result obtained using the breathalyzer may not be too high. 
The total time for weathering is twelve hours.
In addition to these data, it is also necessary to take into account the individual characteristics of each organism, in particular, gender, height, weight, health status, etc.
In any case, the later a person who has drunk on the eve of alcohol gets behind the wheel, the safer it will be for himself and the people around him.

What factors affect the time of withdrawal of alcohol from the body
The time for the withdrawal of alcohol from human blood is determined by the following factors:
- Liver condition , since it is through it that most of the ethanol is removed from the body. Accordingly, the performance of an organ directly depends on its health.
- Features of drinking alcohol . If you consume a large amount of strong alcoholic beverages for a short time, then severe intoxication cannot be avoided. Whereas the consumption of alcohol in relatively small portions, which alternate with a snack, will provide a moderate level of ethanol in the blood.
- Availability of snacks , due to which the process of absorption of alcohol is much slower. While drinking alcohol on an empty stomach will ensure the rapid onset of severe intoxication.
- Physical parameters and a person's attitude to alcohol . In a tall and large person, intoxication occurs much more slowly than in a skinny and short one. For women and the elderly, strong drinks act much faster and stronger than for men and young people. And if a person abuses alcohol, then even a small dose can cause him severe intoxication.
- Emotional condition . It all depends on the specific circumstances. If a person is excited and in a state of excitement, then his nervous system will respond much faster to alcohol than in a balanced state. On the other hand, strong arousal can completely or partially neutralize the effect of alcohol.
- Physical condition and environment . The time of withdrawal of alcohol is also influenced by the presence of chronic diseases in a person, the use of medicines by him, as well as the conditions surrounding him. In a hot room, weathering takes much longer than in a cool and well-ventilated room.
Methods by which you can speed up the time of removing alcohol from the human body
It should be noted right away that there is no miraculous method that allows you to speed up the process of removing alcohol from the body.
The only significant factor in this regard is time. But there are a number of recommendations on how to speed up the removal of alcohol from the body.
First of all, it must be taken into account that a significant part of alcohol is excreted through the bronchi and lungs.
Therefore, at the first signs of intoxication, it is recommended to take a walk for some time in the fresh air. In addition, an abundant intake of table water will increase urination, which will ensure the rapid elimination of alcohol. 
Tea with lemon also has a good effect, since vitamin C contributes to the weathering of ethanol.
Cool water will help you recover faster after a heavy drink. In the warm season, it is best to take a contrast shower, and in winter - to massage your feet with fresh snow.
If the surrounding conditions do not allow any of the above, then you can simply wash with cool water.
It must be borne in mind that these measures will not change the level of ethanol concentration in the blood. They will only help to hide the external manifestations of intoxication. Therefore, driving in this state is strongly discouraged.
Firstly, it is extremely dangerous for the driver himself and casual pedestrians.
And thirdly, laboratory tests unequivocally diagnose the presence of a state of intoxication.
The topic of drunk drivers is now very common in the media, and the state introduces a lot. What to do if you have been drinking and need to drive soon? How to determine if there is alcohol in the blood? For this purpose, it was developed alcohol calculator online. He quite accurately calculates the time for removing alcohol from the blood, after which you can drive a car. It is worth remembering that even if you have or, this will not save you from disaster if you drive drunk. To obtain accurate calculation results, Widmark and Seidl formulas are used, which are used by forensic scientists. This alcohol calculator can be considered one of the most accurate. Be sure that our calculator will calculate as accurately as possible after what time after drinking alcoholic beverages you can drive.
Think about whether you need such consequences?
Remember that the driver is responsible not only for himself, but for the life and health of passengers.
ppm calculator
Studies have shown that approximately 30% of accidents occur because the drivers were in a state of intoxication. In order not to put yourself in danger, never get behind the wheel drunk, even a little. Use alcohol calculator online and determine when you can drive. Now you can easily lose your license if there is even a little alcohol in your blood. Therefore, use the calculator's capabilities at 100%.
Remember that the results of calculations on a calculator are not evidence in court or a replacement for a breathalyzer. The time for the elimination of alcohol and blood is individual for each person, so for the calculation we took the average data. Developers disclaim all responsibility associated with its use.
The degree of intoxication of a person
There are several degrees of intoxication of a person, in which in no case should you drive, even if you need to get to the nearest corner. It doesn't even guarantee you a successful journey.
Mild degree (0.5 - 1.5 ppm) - a person becomes more courageous, sociable, active, feels comfortable, muscles relax. This degree manifests itself immediately after drinking alcoholic beverages.
The average degree (1.5 - 2.5 ppm) - the tongue begins to weave, it is difficult to understand a person, coordination of movements is impaired, partial memory loss is possible. Just in this degree of intoxication, people often quarrel or start a fight.
Strong degree (2.5 - 3 ppm) - slurred speech, loss of coordination, memory loss, loss of consciousness or spontaneous urination is possible.
Alcohol poisoning occurs at 3-5 ppm of alcohol in the blood. Such a binge can even end fatally. If there are more than 5 ppm in the blood, it is almost impossible to save a drunk without special drugs and skills.
How many ppm is allowed
In accordance with the most recent regulations, the following levels of alcohol in the driver's body are allowed:
- 0.16 ppm in exhaled air;
- 0.35 ppm in blood;
We have taken these laws into account, so our calculator provides answers in accordance with the new amendments to the rules.
In general, it is better to play sports. Then you are not afraid of any breathalyzer.
The driver often becomes the cause of accidents, which often end in death. To prevent this, a law was passed in Russia that clearly indicates what the permissible rate of alcohol is while driving, and devices have been developed that measure the level of ethanol in the inhaled air. In addition, special alcohol tables were created for motorists, allowing you to find out the approximate time after which a person will be able to drive.
According to studies, even fifty grams of vodka, which is equal to seven to nine grams of ethanol in the blood, have a negative effect on the psyche, impair reaction, attention, reduce intelligence, and logical thinking. It is especially dangerous that in such a situation, under the influence of ethanol, a person ceases to adequately evaluate his actions. For example, the driver may feel that he is driving a car much better than before, carefully watching the road. This situation is extremely dangerous for a motorist and other people whose activities require maximum concentration, accuracy and ingenuity: any mistake can cost a life.
Such a dose of intoxication is usually invisible to others, and often to the driver himself, and therefore is often ignored: the first visible symptoms appear after drinking 20-30 g of ethanol (100-200 g of vodka). Also, many people forget about the residual alcohol content in the blood, when it seems to a person that he is absolutely sober: even a small dose of alcohol is excreted very slowly. Therefore, until the ethanol is completely out, you can not drive a car.
This should be especially taken into account after drinking, because after heavy drinking it often happens that you can’t drive not only today, but also during the day and even more. It depends not only on the dose of alcohol, but also on the following factors:
- Human gender - ethanol is excreted from the female body twenty percent longer.
- Weight - the lighter the person, the longer the time needed for.
- The strength of the drink - the lower the proportion of ethanol in the drink, the faster it will be removed from the body.
- The quality of alcohol - carbon dioxide accelerates the absorption of ethanol into the blood. Therefore, the speed and degree of intoxication in this case will be faster.
- Health of internal organs, especially the liver, excretory system, lungs: about 90% of alcohol is processed in the liver, the remaining ten are excreted in a series of sweat, urine, breath (therefore, breathalyzers are able to determine the level of alcohol by exhaled air).
- Whether the person drank alcohol on an empty stomach, or had a heavy meal.
- The amount of food a person ate after drinking alcohol.
- Snack quality.
All these factors must be taken into account when calculating the amount of ethanol in the blood. It is also advisable to use not only the table, but also to buy a breathalyzer: when calculating the level of alcohol, errors are possible, which the device, by showing the amount of ethanol of exhaled vapors in ppm, will help to avoid.
measure
The level of alcohol in the exhaled air is usually measured in ppm. So called one thousandth of a share or one tenth of a percent. Therefore, if the device showed values of 1.5‰, this means that one liter of blood contains one and a half milliliters of ethanol.
Currently, according to Russian legislation, the permissible rate of alcohol while driving should not exceed 0.34 ppm or 0.16 mg per liter of exhaled air. Such an amount of ethanol is acceptable given that breathalyzers may show an error, and also because a slight increase in ethanol in the blood is possible in the following situations:
- the person drank some juices, kvass, kefir;
- used medicines that contain alcohol;
- with diseases of the upper respiratory tract;
- diseases of the oral cavity;
- toothpaste.
The level of ethanol, although in these cases, rises, but slightly and not for long, so after a few minutes the device will show that the amount of ppm has fallen. Because of this, any excess of the norm in the driver’s blood is unacceptable, and if the traffic police device detects a state of intoxication during the check, there will be a fine. Ideally, the amount of ethanol in the air exhaled by a motorist should be zero, since alcohol affects the response of a motorist even in very small quantities.
For example, if the device shows that the ethanol content ranges from 0.2 to 0.5 ppm, this means that it is difficult for the driver to assess the speed at which the light sources are moving, as well as their size, due to a decrease in concentration and attention. With a higher amount of alcohol, from 0.5 to 0.8 ppm (this dose is equal to 1 liter of beer or 150 g of vodka), he begins to judge distance poorly, his eyes switch to different light sources worse, react poorly to red, there is a loss balance.
If the device for determining alcohol in the blood shows that the number of ppm ranges from 0.8 to 1.2, this means that the person has a narrowed angle of vision.
With this degree of intoxication, the driver's peripheral vision deteriorates, due to which he significantly loses the ability to see with peripheral vision, and is unable to assess the situation. If the dose that the breathalyzer showed is 1.2 ppm (1.5 liters of beer or 500 g of vodka), this indicates a high degree of intoxication, when the driver is no longer able to drive the car. When the determination of the amount of alcohol in the blood showed 4 ppm, the person may die.
How to calculate the withdrawal of ethanol from the body
You can find out the approximate time when alcohol is completely out of the body, if a man drank 100 grams of alcohol, you can from the following table (for women, these figures must be multiplied by 20%):
| Human weight | 60 kg | 70 kg | 80 kg | 90 kg | 100 kg |
| Beer 4% | 0 h 34 | 0 h 31 | 0 h 27 | 0 h 25 | 0 h 20 |
| Beer 6% | 0 h 51 | 0 h 46 | 0 h 40 | 0 h 36 | 0 h 30 |
| Gin tonic 9% | 1 h 19 | 1 h 08 | 1 hour | 0 h 50 | 0 h 50 |
| Champagne 11% | 1 hour 35 | 1 hour 23 | 1 hour 15 | 1 h 05 | 1 hour |
| Port wine 18% | 2 hours 38 | 2 hours 15 | 2 hours | 1 hour 45 | 1 hour 35 |
| Tincture 24% | 3 hours 28 | 3 h | 2 hours 40 | 2 hours 20 | 2 h 06 |
| Liquor 30% | 4 hours 20 | 3 hours 45 | 3 hours 15 | 2 hours 55 | 2 hours 40 |
| Vodka 40% | 5 hours 50 | 5 o'clock | 4 hours 20 | 3 hours 55 | 3 hours 30 |
| Cognac 42% | 6 o'clock 07 | 5 hours 15 | 4 hours 35 | 4 hours | 3 hours 40 |
Leaving the table, it is obvious that beer is not such a harmless drink as many believe it to be. It takes more than half an hour for a man weighing 60 kg to remove half a glass of a drink from the body, and even more for a woman. This is explained by the fact that in a liter of drunk beer there is the same amount of ethanol as in 100 g of vodka or 400 g of wine.
If a person drank 500 g of alcohol, much more will be required. In this case, you can make an approximate calculation of the time when it is allowed to drive, from the table below. It is worth noting that time is kept from the last dose of alcohol taken, so if a person has been drinking for some time, the period may be less:
| Human weight | 60 kg | 70 kg | 80 kg | 90 kg | 100 kg |
| Beer 4% | 2 hours 55 | 2 hours 30 | 2 hours 10 | 2 h | 1 hour 45 |
| Beer 6% | 4 hours 20 | 3 hours 45 | 3 hours 17. | 2 hours 55 | 2 hours 40 |
| Gin tonic 9% | 6 h 30 | 5 hours 40 | 4 hours 55 | 4 hours 20 | 4 hours |
| Champagne 11% | 8 o'clock | 6 h 52 | 6 o'clock | 5 o'clock 20 | 4 hours 50 |
| Port wine 18% | 14 o'clock | 11 o'clock 10 | 9 h. 50 | 8 hours 45 | 7 hours 55 |
| Tincture 24% | 5:30 p.m. | 14h57 | 13 o'clock | 11:40 a.m. | 10:30 |
| Liquor 30% | 21h 46 | 18h40 | 4 pm 20 | 14h35 | 13 o'clock |
| Vodka 40% | 29 hours | 24 h 55 | 21 h. 46. | 19:25 | 5:25 p.m. |
| Cognac 42% | 30 h. 30. | 26h05 | 22 h 51 | 20 hours 20 | 18h20 |
If a person drank more than one hundred grams, but less than five hundred, you can make calculations by calculating the average value. For example, if 300 g of vodka was drunk, then in a person whose weight is 60 kg, alcohol will come out of the blood after 17 hours and 24 minutes. For a fatter man, weighing 100 kg, the calculation shows a shorter period: 10 hours 26 minutes. In any case, such a calculation means that it is better not to drive today.
It should be noted that the submitted data are conditional, since much depends on the individual characteristics of the organism. Therefore, to be sure, in order not to be fined by the traffic police, and also not to provoke an accident, putting your life and other people at unnecessary risk, when making a calculation, it is better to throw in two or three hours. A more correct option to determine the degree of intoxication would be to purchase a breathalyzer, and after the time indicated in the table, take a test. If the device shows that everything is in order, you can go without fear of being fined by the traffic police.
Why You Shouldn't Shorten Your Waiting Time
When calculating, it should be borne in mind that if strong alcohol is diluted with water or juice, this does not reduce the effect of ethanol on the body, since the amount of alcohol drunk has not changed. It is impossible to avoid alcohol intoxication if you eat well before drinking. A full stomach will only mitigate the negative impact of alcohol on the body, reducing the load on the liver, and intoxication will come later.
Also, do not think that a cold shower, strong coffee, a walk in the fresh air will affect the rate of ethanol excretion from the body and reduce the degree (although they can relieve hangover symptoms). Even if a person feels normal, you need to get behind the wheel no earlier than the time indicated in the table that has passed since the last time you took alcohol. If the traffic police during the inspection finds that there is no permissible level of alcohol in the blood, the fine for violating the law of Russia is 30 thousand rubles, and the offender loses his license for a period of one and a half to two years.
