"How many drinks does it take to become legally drunk?"
That’s the wrong question to ask because it presupposes that there are a fixed number of drinks that are acceptable before you get behind the wheel. That’s not the case. For example, if you are taking medication, one drink could put you into the "DUI" category. For some people, it often takes very little alcohol to become legally drunk and certain physical characteristics such as weight, gender and body fat percentage can all be factors in the equation. Eating can also affect your outcome – you are more likely to fail a blood alcohol test if you do not eat. So, practically, if you’re wondering how many drinks you can have before driving, the best answer is ‘None.’ Legally, in all states you should not be operating a motor vehicle with a .08 percent blood alcohol concentration (BAC). In other words, whether or not you consider yourself "drunk," the law considers you to be an offender if your BAC is above .08%.
