How many hours after drinking can you drive?

If you drink one bottle of beer or half a tael of liquor, it is recommended to wait 6 to 10 hours before driving; if you drink 2 bottles of beer or 3 taels of low-alcohol liquor, it is advised to wait 10 to 24 hours before driving; if the alcohol content is higher or the amount consumed is larger, you should wait at least 24 hours before driving. Drunk driving refers to the act of driving when the blood alcohol concentration of the driver is equal to or greater than 20 milligrams per 100 milliliters but less than 80 milligrams per 100 milliliters; driving under severe intoxication refers to the act of driving when the blood alcohol concentration of the driver is equal to or greater than 80 milligrams per 100 milliliters.
I remember a party last summer where a friend tried to drive home 6 hours after drinking several bottles of beer, only to crash into a guardrail on the way. Alcohol breaks down slowly in the body, heavily influenced by body weight and the amount consumed. It's generally recommended to wait at least 8 to 12 hours or more, as the concentration may halve in 2 hours after one beer, but more drinks require longer waits. Metabolism slows further with lighter body weight or drinking on an empty stomach. To be safe, it's best not to risk driving; use a designated driver or taxi, and retrieve your car the next day. That incident taught me that zero-alcohol driving is the most reliable way to protect both yourself and others.
Alcohol metabolism is a scientific process primarily carried out by the liver, which processes approximately 10 to 15 milliliters of alcohol per hour. This means if you consume three glasses of wine, each containing 14 grams of alcohol, totaling 42 grams, dividing by 10 gives 4 hours to halve the amount, but complete elimination may take up to 8 hours. However, this time varies from person to person; a 60kg woman metabolizes alcohol slower than an 80kg man, and food intake also affects absorption speed. The safe method is to wait until the blood alcohol concentration drops below 20mg/100ml, typically at least 8 hours. I recommend using a free app or online tool for estimation, such as inputting your weight and alcohol consumption, which can help calculate the safe time. Never rely on feeling to drive.
