c.n.

Definizione

The amount of alcohol in the blood expressed as a percent: grams of ethanol per 100 milliliters (deciliter) of blood.

Nota

BAC refers to the amount of alcohol contained in a person's blood. It is measured as weight per unit of volume. Typically this measurement is converted to a percentage such as 0.10%, which indicates that one-tenth of a percent of a person's blood is alcohol.

Contesto

In 2011, nearly 10,000 people were killed nationally in motor vehicle traffic crashes that involved at least one driver or motorcycle rider with a blood alcohol concentration of .08 or higher.
