What's the big deal about driving after you've had a few drinks, anyway? Just in case you missed all the commercials, public safety announcements, and were never taught this is in school, here is a brief refresher.
Drinking alcohol affects your judgment, reflexes, depth perception, and other cognitive functions that are necessary to drive safely. People that drink and drive are far more likely to get in a serious auto accident than sober drivers. Whenever you drink, alcohol is absorbed into your bloodstream through the lining of your stomach and small intestine. The alcohol in your bloodstream directly affects your brain, with the amount of impairment increasing as the level of alcohol in your blood increases. By the time you reach Texas' legal limit of .08, your muscle control is poor, your judgment is impaired, and your ability to detect danger is reduced significantly. In other words, you are in no condition to drive!
How do you know when you've had too much? Well, everyone's tolerance for alcohol is different, and your BAC can be affected by factors like weight, gender, and how much you've had to eat. The general rule is to consume no more than 1 drink per hour, with one drink being 12 oz of beer, 5 oz of wine, or 1 single shot of liquor. However, this is not foolproof, due the factors mentioned above and also to the fact that if you have a low tolerance for alcohol you could become impaired at a BAC below the legal limit of .08. So, the best defense against a DWI is not to drink and drive at all.
