The chart below is a
guideline to how Alcohol affects the human body. Many people don't
realize that just because they feel fine - they could easily be
legally impaired and not aware of the side effects of alcohol. This
diagram includes males and females but is only a guideline
since there are many other factors that may contribute to how
intoxicated a person may become. One of the biggest myths is
establishments serving alcohol have perfect measurements of what is
considered a "drink" by this guide. For example, a "tall order" or
stronger version of your favorite beverage could be considered two
to three drinks using this table.

To estimate your blood
alcohol content (BAC) - first locate your body weight on the left side
and then add one square to the right for each drink you have taken.
Remember that a
'drink' here is considered the equivalent of: (1) 12 oz. regular beer, (1)
7-8 oz. strong beer, (1) 5-6 oz. glass of wine, or (1) shot (1-2 oz.)
of hard liquor.
Your body burns off
alcohol at the approximate rate of .015% BAC each hour. Multiply .015%
times the number of hours since you had your first drink. Subtract
that percentage from the first BAC reading you figured out - this will
give you an approximate idea of your BAC.
As you can see above - it
doesn't take much to impair someone. At a .04 BAC you are considered
'somewhat impaired' to where your motor functions and logical
reasoning are decreased. Commercial Vehicle Operators can be arrested
for DWI at a .04%.
At a .08 BAC, you are considered 'legally
impaired' by Minnesota State Law and scientific evidence has
proven your vision, reflexes, and
concentration are significantly decreased.
Anyone at a .04-.07 BAC
level is taking a huge risk if they get behind the wheel of a car and
drive - their own life, their ability to drive safely, and the lives
of others they might not be aware of are now in danger. A higher BAC
only multiplies that risk even more. You can still be arrested below
the legal limit but anyone at .08% BAC or higher is
automatically processed for DWI.
The general rule - Don't
Drink if your going to be operating a motor vehicle.
