The acronym DUI stand for driving while intoxicated and driving under the influence. These terms describe the crime of operating a motor vehicle while under the influence of alcohol or drugs.
A driver’s intoxication level is determined by his or her blood alcohol content (BAC), which is a measure of the concentration of alcohol in the bloodstream. It is normally measured as mass per volume. Someone with a BAC of 0.02% has 0.02 grams of alcohol per 100 grams of blood. Each county and state in the United States has its own legal blood alcohol limit for driving. The legal percentages range from as low as 0.02% to as high as 0.08%. Everywhere in the United States it is illegal to drive with a BAC of 0.08% or higher.

In 2006, approximately 17, 600 people died in traffic crashes involving alcohol. In that same year, over 1.46 million drivers were arrested for driving under the influence of alcohol or drugs.
