BAC by drinking three &ounce ( 1 20 ml) glasses of wine or three mixed drinks if each had 1-1/2 ounces (45 mlj of a liquor like whiskey, gin or vodka. It's the amount of alcohol that counts. For example,if the same person drank three double martinis (3 ounces or 90 m l of liquor each) within an hour, the person's BAC would be close to 0.12percent. A person who consumes foodjust 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. Since alcohol is carried in body water, this means that a woman generally will reach a higher BAC level than a man of her same body weight when each has the same number of drinks. The law in many U.S. states sets the legal limit at a BAC of 0.10 percent. In a growing number of U.S. states, and throughout Canada, the limit is 0.08 percent. In some other countriesit's even lower. The BAC limit for all commercial drivers in the U.S. is 0.04 percent. The BAC will be over 0.10percent after three to six drinks (in one hour). Of course, as we've seen, it dependson 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 0.f 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 0.05percent. Statistics show that the chance of being in a collision increasessharply for drivers who have a BAC of 0.05 percent or above. A driver with a BAC level of 0.06 percent has doubled his or her chance of having a collision.At a BAC level of 0.10 percent, the chance of this driver having a collision is twelve times greater; at a level of 0.15 percent, the chance is twenty-five times greater! The body takes about an hour to rid itself of the alcohol in one drink. No amount of coffee or number of cold showers will speed that up. "I'll be 4-3
