Blood/Breath Alcohol Concentration (BAC) is the amount of
alcohol in the bloodstream or on one's breath. BAC is expressed as
the weight of ethanol, measured in grams, in 100 milliliters of
blood, or 210 liters of breath. BAC can be measured by breath,
blood, or urine tests.
- Louisiana defines legal intoxication for purposes of driving
as having a BAC of 0.08 or greater, in most cases. But alcohol
may affect driving skills at BACs of 0.05 or even lower.
- Driving skills, especially judgment, are impaired in most
people long before they show signs of drunkenness. The public
usually associates BAC with "drunk driving." But it's
more accurate to refer to "alcohol-impaired" driving
because you do not have to be "drunk" to be impaired
in your ability to safely drive a car.
Use this calculator to instantly compute your estimated
blood/breath alcohol concentration.
