DWI Fact #3: How much is too much? That’s the wrong question to ask because it assumes that there are a fixed number of drinks that are acceptable before you get behind the wheel. That is not the case. For example, if you are taking medication, one drink could put you at risk. 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.”
