The obvious way to solve the leading highway safety
problem is for people never to drink alcohol and then
drive. But what if people do? How much is "too much"
if the driver plans to drive? It's a lot less than many
might think. Although it depends on each person and
situation, here is some general information on
the problem.
The Blood Alcohol Concentration (BAC) of someone
who is drinking depends upon four things:
D
The amount of alcohol consumed
D
The drinker's body weight
D
The amount of food that is consumed before and
during drinking
D
The length of time it has taken the drinker to
consume the alcohol.
According to the American Medical Association, a
-
180 lb. (82 kg) person who drinks three 12
(355 ml) bottles of beer in an hour will end up with a
BAC of about 0.06 percent. The person would reach the
same BAC by drinking three 4
of wine or three mixed drinks if each had 1
(45 ml) of a liquor like whiskey, gin or vodka.
-
ounce
-
ounce (120 ml) glasses
-
1/2 ounces
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.
