Can One Glass of Beer Be Detected as Drunk Driving?

One glass of beer can be detected as drunk driving. Drunk driving refers to a driver's blood alcohol content (BAC) being equal to or greater than 20 milligrams per 100 milliliters but less than 80 milligrams. If the BAC exceeds 80 milligrams per 100 milliliters, it is considered driving under severe intoxication. Typically, consuming one or two glasses of beer, approximately one ounce of 12-degree red wine, or half an ounce of 50-degree liquor can reach the drunk driving standard. After drinking, even if one is not intoxicated, alcohol affects the central nervous system, putting the body's nervous system in a state of anesthesia and inhibition. This can lead to visual impairment, reduced tactile sensitivity, sluggish motor reflexes, and fatigue. Driving requires high concentration to anticipate road conditions, and when these effects occur, the likelihood of traffic accidents increases, posing a threat to the safety of oneself and others. Therefore, it is advised not to drive after drinking and not to drink when driving.
I have to say whether a beer can lead to a DUI really depends on individual circumstances. Having driven for years, I sometimes stop after just one regular beer during social occasions. But once at a friend’s gathering, I had one beer and coincidentally encountered a traffic police check—surprisingly, it showed a slight alcohol level exceeding the limit. I weigh 70 kg, and after drinking a 350ml beer with 5% alcohol, my BAC measured 18mg/100ml, almost exceeding the 20mg standard. Meanwhile, a friend weighing only 50kg drank the same beer and tested at 25mg directly. So yes, one beer can indeed get you flagged for drunk driving, especially for those with slower metabolism, drinking on an empty stomach, or lighter body weight—don’t take it lightly. Breathalyzers are highly sensitive, and even one drink can slow reaction times, making accidents more likely. My advice? Avoid any alcohol before driving to steer clear of trouble.
