Since alcohol is carried in body water, this means that a woman generally will reach a higher BAC level than a man of hersame body weight wheneach has the same number of drinks. The law in manyU.S. states sets the legal limit at a BAC of 0.10 percent. In agrowing number of U.S. states, and throughout Canada, the limit is 0.08 percent. In some other countries, it's even lower. The BAC limit for all commercial drivers in the United States 0.04 percent. is The BAC will be over 0.10 percent after three to six drinks (in one hour). Of course, as we've seen, it depends on how much alcohol is inthe drinks, and how quickly the persondrinks them. But the abilityto drive is affected well belowa BAC of 0.10 percent. Research shows that the driving skills of many people are impaired at aBAC approaching 0.05 percent, and that theeffects are worse at night. All drivers are impaired at BAClevels above 0.05 percent. Statistics show that thechance of being in a collision increases sharply for drivers who have a BAC of 0.05 percent or above. A driver with a BAC level of 0.06 percent has doubledhis or her chance of having a collision. At a BAC level of0.10 percent, the chance of this driver having a collision is12 times greater; at a level of 0.15 percent, the chance is 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.
