The blood alcohol content in the blood is less than a certain standard, in order not to be considered a DUI. Not to see how long to drive, but to see the blood alcohol content, the driver's blood alcohol content is greater than or equal to 20mg/100ml, less than 80mg/100ml of driving behavior can be recognized as DUI. So you need to wait until the alcohol content is less than 20mg/100ml before you can drive. Because everyone's metabolic rate is different.

Alcohol can be found in human blood in 5 minutes after drinking, and more than two hours later alcohol will be fully absorbed by the body. The body, on the other hand, metabolizes alcohol much more slowly than it absorbs it.

Everyone's alcohol metabolism rate is different again, and the same person's alcohol metabolism rate is different at different times or in different environments.

①Drinking a bottle of beer or a glass of wine

The metabolism of alcohol in the human body has a limit, and generally can only metabolize 10 grams to 15 grams of alcohol per hour. If you drink only one beer or one glass of red wine, it will take at least 6 to 10 hours of metabolism before you can drive again.

②Drinking 2 bottles of beer or 3 pairs of low-grade liquor

It's best to drive after 20 to 24 hours, or longer if you're drinking a higher alcohol content and a larger amount of alcohol.

In general, the degradation half-life of alcohol in the body is greater than six hours. Depending on individual differences, the metabolism time may be longer than 10 hours or even 24 hours. So according to general calculations, the general dissipation time of alcohol in the body is 10 to 24 hours. Sometimes the night after drinking a sleep the next morning nothing, but a go out to be checked, physiological is nothing to reflect, but the alcohol is still in the body is not clean, so after drinking 10 ~ 24 hours before driving is more scientific.

Legal basis: "Vehicle Driver Blood, Breath Alcohol Content Thresholds and Tests" Article 4

"Vehicle Driver Blood, Breath Alcohol Content Thresholds and Tests" Article 4

The first

Vehicle Driver Blood Alcohol Content Greater than or Equal to 20 milligrams per 100 milligrams. milliliter is less than 80 milligrams per 100 milliliters, is drinking and driving. If it is greater than or equal to 80 milligrams per 100 milliliters, it is drunk driving.

Second paragraph

The vehicle driver's breath alcohol content by 1:

2200 ratio relationship converted to blood alcohol content, that is, the breath alcohol content value multiplied by 2200 is equal to the value of blood alcohol content.
