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.
Since alcohol is carried in body water, this means that a
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 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
of
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 0.05 percent.
Statistics show that the chance 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 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 12 times greater; at a
level of 0.15 percent, the chance is 25 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
