Can I drive the next morning after drinking two bottles of beer at night?

You can drive. Under normal physical conditions for an average person, beer should be completely metabolized within four to six hours. Below is relevant information: Drunk driving standard: According to the "Threshold and Testing of Blood and Breath Alcohol Content for Drunk Driving of Vehicle Drivers" issued by the National Quality Supervision, Inspection and Quarantine Bureau, drinking and driving refers to driving behavior where the alcohol content in the driver's blood is greater than or equal to 20mg/100ml but less than 80mg/100ml. Drunk driving refers to driving behavior where the alcohol content in the driver's blood is greater than or equal to 80mg/100ml. Time to metabolize alcohol: Generally, an adult metabolizes alcohol at a rate of 10-15 milliliters per hour. This means that after drinking one bottle of beer, it takes 2-3 hours before you can drive; after drinking two bottles of beer, it takes 4-8 hours before you can drive. Some experts point out that it takes at least 10 hours for alcohol to be completely degraded and undetectable in the human body, and the safest approach is to wait more than 20 hours to allow the body sufficient time to metabolize the alcohol.
I think this is a problem many people encounter. As a long-time enthusiast studying automotive safety, I must say alcohol metabolism rates are far from uniform—they're influenced by body weight, gender, and even what you ate for dinner the night before. For example, the average body can only process the alcohol equivalent of one beer per hour. If you drink two standard bottles of beer (about 500ml each), you're likely consuming 40-50 grams of alcohol. At normal metabolic rates, it could take 8 to 10 hours to fully eliminate it. But don't assume sleeping it off solves everything, as slow metabolizers may still have blood alcohol concentrations above the legal limit the next morning—in China, the drunk driving threshold is below 0.02% BAC. Additionally, residual alcohol slows reaction times; even if you feel sober, your steering and braking responses will be delayed. Studies show even slight alcohol levels can increase accident rates by up to 30%. I recommend using a breathalyzer or waiting a full 12 hours before driving. Safe driving is no trivial matter—don't risk major consequences for minor conveniences.
