Drinking and driving is not a good idea, regardless of how much alcohol you consumed. You do not have to be rolling drunk to have slower reflexes and impaired judgment, a deadly recipe when behind the wheel. There is a very simple calculator for how much alcohol you should drink before driving: zero. But, we do not always do the smart thing. Figuring out your blood alcohol level using a blood alcohol calculator can save your life, or at least your driving license.
In all U.S. states, a legal blood alcohol limit is 0.08 percents or 0.08 grams of alcohol per 100 milliliters of blood, or 210 liters of breath. You will reach this limit after only three drinks of half ounce of alcohol. Anything over that will bring you a large fine, license suspension, house arrest, community service, alcohol treatment programs, DUI school, car forfeiture or jail time, depending on the amount of alcohol found in your blood or breath and if you were caught doing it if before.
In many states the legal blood alcohol limit is even lower for young, inexperienced and professional drivers.
The most commonly used blood alcohol calculator takes into account your weight in pounds, a number of drinks of 12 oz. of beer or equivalent, your gender, and over how many hours you consumed all that alcohol.
A blood alcohol calculator will give you an estimate of the amount of alcohol in your blood, nothing more. This can be affected by many other factors, such as the food you ate before or while you were drinking, your metabolism, the time elapsed since your last drink, medications you are taking, your general health and many others.
Good bars now have installed their own breathalyzer. You can check if you overdid it, if you do not feel it already, and call a taxi or a friend to drive you home. You can also buy a breathalyzer for as little as $50.
Above legal limit or not, do not drink and drive. Keep in mind that every 48 minutes one American dies in alcohol-related car crash. In 2009, 11000 people and 1,300 children died in drunken driving accidents. Don”t become a statistic.
