Assume that pedestrians or other drivers are going to be careless and make
mistakes. Anticipate what they might do. Be ready for their mistakes.
Rear-end collisions are about the most preventable of accidents. Yet they
are common. Allow enough following distance. It's the best defensive
driving maneuver, in both city and rural driving. You never know when the
vehicle in front of you is going to brake or turn suddenly.
Drunken Driving
Death and injury associated with drinking and driving is a national tragedy.
It's the number one contributor to the highway death toll, claiming
thousands of victims every year.
Alcohol affects four things that anyone needs to drive a vehicle:
Judgment

Muscular Coordination
Vision
Attentiveness
Police records show that almost half of all motor vehicle-related deaths
involve alcohol. In most cases, these deaths are the result of someone who
was drinking and driving. In recent years, some

vehicle-related deaths have been associated with the use of alcohol, with
more than 300,000 people injured.

persons under 2 1, it's against the law in every U.S. state to drink alcohol.
There are good medical, psychological and developmental reasons for these
laws.
The obvious way to solve this 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:
How much alcohol consumed
The drinker's body weight
The amount of food that is consumed before and during drinking
The length of time it has taken the drinker to consume the alcohol
According to the American Medical Association, a 180-pound (82 kg)
person who drinks three 12-ounce (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
