If you want to know how long it takes to drive, the first thing you need to know is the current drunk driving standard in China. According to the relevant regulations issued by the General Administration of Quality Supervision, Inspection and Quarantine, if it is determined to be drunk driving, it means that the alcohol content in the blood of the vehicle driver is ≥20mg/ 100ml, which is lower than 80mg/ml, while drunk driving means that the alcohol content in the blood of the vehicle driver is ≥80mg/ 100ml.
Then, in a more popular way, to achieve drunk driving, in fact, only two bottles of beer or even one bottle of beer are needed. Therefore, even if you only drink a little beer, you'd better not drive in the street easily. Generally speaking, the speed at which adults decompose alcohol is 10~ 15 ml per hour, which means that after drinking a bottle of beer, you need to wait another 2~3 hours before driving, and after drinking two bottles, you need to wait another 4~8 hours before driving.
Then some car owners will ask, can I drink at noon and drive at night? In fact, you have almost answered this question just now. If you drink two bottles of beer at noon, you may not be able to drive at seven or eight in the evening. This is your guess that the decomposition rate of alcohol is within the normal range. If you absorb alcohol slowly and decompose it slowly, you will probably have to wait longer.
Having said that, it's still the same sentence: don't drive after drinking, don't drive, drunk driving will not only threaten the integrity of your own family, but also threaten the integrity of others' families. Therefore, not driving after drinking is a responsible behavior for yourself and others.
