How soon after drinking a glass of wine can you drive?


It’s a rare weekend to have a dinner with three or five friends. Among the bustle and bustle, my friends actually brought a few bottles of wine, but they drank a few glasses despite the hospitality. It’s over, I drove the car out today, and after the party ended, I had to call the driver in desperation. picture

I believe that everyone has had such an experience. Many times, I can’t help but drink a few glasses.

At this time, I will definitely think, if I know how long it takes for the alcohol to “dissipate” after drinking, then I can drive home by myself.

This idea is creative but dangerous, my friend, let me break it down for you:

1. Drunk driving standard

As early as the beginning of learning to drive, we repeatedly learned the criteria for judging drunk driving:

A blood alcohol content of 20-80mg/100mL belongs to drunk driving; a blood alcohol content higher than 80mg/100mL belongs to drunk driving.

This means that as long as you drink one glass of low-alcohol alcohol, it is basically considered drunk driving, and drinking more than two drinks is mostly considered drunk driving.

2. How long after drinking alcohol can I drive?

Although there are differences in alcohol and people’s metabolic abilities are also different, it is difficult to have a uniform standard for how long it takes to drive after drinking. But under normal circumstances, the human body can metabolize 10-15g of alcohol per hour.

For example, at a gathering of old friends, the greedy Lao Xia drinks 1 catty (500g) of liquor. The alcohol content of the liquor is about 200g. Calculated by metabolizing 10g per hour, it will take about 20 hours to completely metabolize 1 catty of liquor.

After drinking a lot at night, the alcohol content in the body is still high after getting up the next day. For some drivers with slow metabolism, it is possible to be found out for drunk driving even within 24 hours.

Therefore, if you drink a small amount of alcohol, such as half a glass of beer or a glass of wine, it is best to wait until 6 hours before driving; half a catty of liquor is not driving for 12 hours; one catty of liquor is not driving for 24 hours.

3. Food and drugs that have been “drunk and driven”

In addition to drinking, there are also drivers who have experienced even more bizarre “drunk driving”-clearly not drinking, but still being found to be drunk and driving.

In fact, this is all because of accidentally eating food and drugs that contain alcohol.

Food examples: Beer duck, fermented bean curd, drunk crab/shrimp, fermented glutinous rice balls, bad chicken/meat, egg yolk pie; lychees, apples, bananas, etc. with high sugar content will also produce alcohol if not stored properly.

Drug category: Huoxiangzhengqi water, cough syrup, various injections, edible mouth fresheners, mouthwash, etc.

In fact, you don’t have to worry too much if you really eat these, because they have very low alcohol content and can dissipate quickly. As long as we finish eating about three hours, we can basically drive.

In daily life, we should not be lucky, and try our best to “do not drink and drive, and do not drink while driving”.

If there is an emergency, we can wait until we are fully awake and the alcohol has completely dissipated, or it is very convenient to call a substitute driver.
