Can a bottle of beer detect drunk driving?

Drinking a beer is also drunk driving.

It is understood that for an adult, the blood content is about 8% of the body weight. That is to say, a person weighing 50 kilograms has a blood content of about 4000ml, and a person weighing 75 kilograms has a blood content of about 6000ml. In this way, a person weighing 75 kg who drinks more than 1200mg but less than 4800mg is drunk driving, and drinks more than 4800mg is drunk driving.

The standard of drunk driving means that the alcohol content in the driver's blood is greater than or equal to 20 mg per 100 ml. Beer is a kind of wine with very low alcohol content, and a can of beer is only about 330-500 ml. Normal adults can generally metabolize to less than 20 mg after drinking for four hours, so a can of beer for four hours will not be detected as drunk driving. When the blood alcohol content of a vehicle driver is greater than or equal to 20mg/ 100ml and less than 80mg/ 100ml, it is regarded as driving after drinking; When the alcohol content in blood is more than or equal to 80mg/ 100ml, it is drunk driving. Even if there is no traffic accident, drunk drivers violate traffic rules, so for the safety of themselves and others, they don't drive after drinking. Some drivers have good physical fitness, good fitness habits and drink on an empty stomach, so their metabolism is fast, so the speed of eliminating alcohol in the blood is faster. But if you eat a snack that you should eat, the speed of eliminating alcohol from your blood vessels will be slower, because you need to digest the food. If the alcohol content is high, the waiting time for digestion will be longer.

You can't detect drunk driving after drinking a bottle of beer for hours.

After drinking a bottle of beer for about three hours, the alcohol concentration in the body is lower than the standard of drunk driving, which is also related to people's weight, beer consumption and alcohol concentration. The half-life of alcohol in human body is 3 hours (related to personal physique), that is, it can be halved to 18mg/ 100ml after 3 hours. According to this calculation, it should be below the drunk driving level of 20mg/ 100ml after three hours, and it is not a drunk driving state. But at this time, although it has not yet constituted a drunk driving standard, the traffic police said that this situation is often the most dangerous. If you are found driving, you will not be punished, but you will still be allowed to stop and rest until the alcohol content is zero before you can continue on the road.
