In all 50 states, the legal limit for drunk driving is a blood alcohol concentration (BAC) level of. 08. A 120-pound woman can reach a. 08 BAC level after only two drinks and a 180-pound man can be at.
According to the NHTSA calculator, he can legally consume a third beer and still drive under the. 08 legal limit.
According to conventional wisdom, your BAC level will remain within safe limits if you consume only one standard drink per hour. As defined by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), a standard drink is half an ounce of alcohol.
As a rule of thumb, two pints of regular-strength lager or two small glasses of wine would put you over the limit. But this isn’t a catch-all rule. Factors like your weight, sex, metabolism and how much you’ve eaten all contribute to how your body processes alcohol, so everyone has different limits.
The truth is that even one glass of wine can make you legally drunk. Many factors affect a person’s tolerance for alcohol. The number of drinks consumed is only one of them. One glass of chardonnay could be all it takes to cause a deadly drunk driving crash.
Therefore, the faster you drink, the higher your blood alcohol level will be.. 08 -. 10 blood alcohol level is considered legally drunk.
Because alcohol metabolism is different for everyone, there is no single answer as to how long a breathalyzer can detect alcohol in a person’s system, but in general, a breathalyzer can first detect alcohol in a person’s system about 15 minutes after it has been consumed and up to 24 hours later.

The average adult takes about an hour to process one unit of alcohol. And there is nothing you can do to speed this up or eliminate the alcohol in your body. 2 pints of lager and 2 pints of cider would take 172 hours from when you’ve stopped drinking before driving.
One hour between beers is insufficient to maintain a balance in your BAC — you’re still consuming it faster than your body is burning it off. If you cut that in half, however ( one beer every two hours), then you’re probably going to maintain a near-zero BAC — depending on your gender, age, weight, and tolerance.
It may take an hour to metabolize a drink, but it takes approximately thirty minutes before you feel alcohol’s effects. This is a good gauge for pacing yourself. Drinking more than one drink every 30 minutes means you are probably drinking too much, too fast.
Unless you weigh 250 lbs or more, two glasses of wine in an hour makes you legally drunk. In order to achieve the same effect with beer, you’d have to consume 3 to 4 of them in an hour. You only have so much time in an hour, and you really need to concentrate on your drinking to get that much beer down.
