Blood alcohol content (BAC), also called blood alcohol concentration or blood alcohol level, is a measurement of alcohol intoxication used for legal or medical purposes. [1] BAC is expressed as mass of alcohol per volume of blood. In US and many international publications, BAC levels are written as a percentage such as 0.08%, i.e. there is 0.8 ...
Under conditions of moderate alcohol consumption where blood alcohol levels average 0.06–0.08 percent and decrease 0.01–0.02 percent per hour, an alcohol clearance rate of 4–5 hours would coincide with disruptions in sleep maintenance in the second half of an 8-hour sleep episode.
Drunk driving is the act of operating a motor vehicle with the operator's ability to do so impaired as a result of alcohol consumption, or with a blood alcohol level in excess of the legal limit. [1] For drivers 21 years or older, driving with a blood alcohol concentration (BAC) of 0.08% or higher is illegal.
In contrast, only 16 percent of those involved in fatal wrecks have BAC levels under 0.08 (and the number is even lower for those specifically in the .05 to .07 range who would presumably be ...

The ratio of venous blood alcohol content to breath alcohol content may vary significantly, from 1300:1 to 3100:1. Assuming a blood-alcohol concentration of 0.07%, for example, a person could have a partition ratio of 1500:1 and a breath test reading of 0.10 g/2100 mL, over the legal limit in some jurisdictions.

The breath alcohol limit for such a person is 0.02%, and any measurable level of alcohol by a breathalyzer is an automatic DUI and driver's license revocation. This crime is punishable by a fine of up $1,000 US dollars and up to 1 year imprisonment after being evaluated by a person certified by the Department of Mental Health and Substance Abuse .
