victims every year. Alcohol takes away three things that anyone needs to
drive a vehicle.

Police records show that half of all motor vehicle-related deaths involve
alcohol-a driver, a passenger or someone else, such as a pedestrian, had
been drinking. In most cases, these deaths are the result of someone who
was drinking and driving. Over 25,000 motor vehicle-related deaths occur
each year because of alcohol, and thousands of people are injured.
Just how much alcohol is
too much if a person plans
to drive? Ideally, no
one should drink alcohol and then drive. But if one does, then what's "too
much"? It can be 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 Content (BAC) of someone who is drinking depends upon
four things:
*
How much alcohol is in the drink.
Q
The drinker's body weight.
Q
The amount of food that is consumed before and during drinking.
*
The length of time it has taken the drinker to consume the alcohol.
