Since alcoholis carried in body water, this means that a woman generally will reach a higher BAC level than a man of her samebody weight when each has the same number of drinks. The law in many U.S. states setsthe legal limit at a BAC of 0.10 percent. In a growing number of U.S. states, and throughout Canada, the limitis 0.08 percent. In some other countries,it's even lower. The BAC limit for all commercial driversin the United States is 0.04 percent. The BAC will be over 0.10 percent after three tosix drinks (in one hour). Of course, as we've seen, it depends on how much alcohol is in the drinks, and how quickly the person drinks them. But the ability to drive is affected well below a BAC of 0.10 percent. Research shows that the driving skills of many people are impaired at a BAC approaching 0.05 percent, and that the effects are worse at night. All drivers are impaired at BAC levels above 0.05 percent. Statistics show that the chance of being in a collision increases sharply for drivers who have a BAC of 0.05 percent or above. A driver with a BAC levelof 0.06 percent has doubled hisor her chance of having a collision. At a BAC levelof 0.10 percent, the chance of this driver having a collision is 12 times greater; at a level of 0.15 percent, the chanceis 25 times greater! It's the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour, the person's BAC would be close to 0.12 percent. A person who consumes food just before or during drinking will have a somewhat lower BAC level. There is a gender difference, too. Women generally have a lower relative percentage of body water than men. 4-3
