As People Are Out This Holiday Weekend, Drinking Alcoholic Beverages Is Probably Going To Be Involved. But For Some That Means Only A Few Drinks. Some people avoid hard liquor because they think it has more alcohol than other choices but does it? Todays question on the Texas Drivers Quiz: True or False? A 12-ounce bottle of beer, a 5- ounce glass of wine and a mixed drink with an ounce and a half of 80-proof liquor generally have the same alcohol content? The answer is True. All three of these have relatively the same amount of alcohol, but many factors determine how alcohol will affect you. State law says youre legally intoxicated when your blood or breath alcohol concentration is .08 or more. For some people, that can be as few as two to three beers in one hour. At this recent law enforcement training session, volunteers were carefully monitored as they drank alcohol. Factors such as body size, gender, metabolism - even how much food had been eaten - had a direct impact or breath alcohol levels. Thats why experts say to never assume you can avoid becoming intoxicated by avoiding the hard stuff. Even a little alcohol can greatly impair your ability to drive safely.
