Step-by-step explanation:
The subject of this question is Health as it pertains to the legal intoxication level for DUI (Driving Under the Influence) for individuals over the age of 21.
To determine if someone is legally intoxicated, their Blood Alcohol Concentration (BAC) is measured. In most countries, including the US, the legal limit is a BAC of 0.08% by volume. This can be measured through blood or breath testing, such as using a portable device called a Breathalyzer.
The BAC level determines the level of alcohol intoxication, with higher levels causing more severe impairment, even leading to unconsciousness or death. To achieve sobriety after reaching the legal intoxication level, it typically takes at least five hours for the liver to metabolize the alcohol fully.
