Step-by-step explanation:
In most US states, it is illegal for individuals over the age of 21 to drive with a blood alcohol content (BAC) level of 0.08% or higher.
At this BAC level, an individual is considered legally intoxicated and impaired, which greatly increases the risk of accidents and harm to oneself and others on the road.
It's important to drink responsibly and find alternative transportation options if you plan on consuming alcohol.
