Session 2 – Detection and General Deterrence
Standardized Field Sobriety Test Course
How much can a person drink before
becoming impaired?
Depends…
• Time?
• Sex?
• Size?
• Drinking
on empty stomach?
…A couple of beers can do it!

Dose Response Relationships
People
sometimes ask, "how 'high' is 'drunk'?" What is the "legal
limit" for "drunk
driving"?
How much can a person drink before becoming "impaired"?
There
is no simple answer to these or similar questions, except to say that any
amount
of
alcohol will affect a person's ability to drive to some degree. It is true that
the laws of
nearly
all States establish a BAC limit at which it is explicitly unlawful to operate
a
vehicle.
In those cases, that "limit" is 0.08 BAC. But every State also makes
it unlawful
to
drive when "under the influence" of alcohol, and the law admits the
possibility that a
particular
person may be under the influence at much lower BACs.

• 175

• Drinking
on an Empty Stomach
How Much Alcohol to Reach a BAC
of 0.08
2-54
How
much alcohol does someone have to drink to reach these kinds of BACs?
Obviously,
as we've already seen, it depends on how much time the person spends
drinking,
on whether the person is a man or a woman, on how large the person is, on
whether
the drinking takes place on an empty stomach, and on certain other factors.
But
let's take as an example a 175 pound man. If he drinks two beers, or two shots
of
whiskey,
in quick succession on an empty stomach, his BAC will climb to slightly above
0.04.
Two more beers will boost him above 0.08. One more will push him over 0.10. In
one
respect, then, it doesn't take very much alcohol to impair someone: "a
couple of
beers"
can do it.
