Blood Alcohol Content (BAC)
Blood Alcohol Content (BAC) is the level of alcohol in the bloodstream
of a person arrested for driving under the influence of alcohol (DUI/DWI).
It is used in court as evidence of DUI. The most common method of determining
BAC is through a breath test (Breathalyzer), although blood and urine testing
is also done. In the state of California, if a driver’s Blood Alcohol
Content is found to be 0.08% or more, the breath test results can establish
a presumption of drunk driving. Blood Alcohol Content is also referred
to as a Blood Alcohol Level.
