Sample question from test 3
alcohol
According to the Louisiana guide, about how long does the body take to remove one normal drink from circulation?
- About one hour
- About fifteen minutes
- About three hours
- Only after a full night's sleep
Answer: About one hour. The guide says the body takes about an hour to get rid of one normal drink from the circulatory system. That is an approximate processing statement, not a promise that a person will be safe or unimpaired after waiting exactly one hour. The shorter fifteen-minute choice understates the time, while three hours and a full night's sleep are not the guide's stated interval for one drink. Alcohol affects judgment and skill, and individual effects vary. The reliable driving cue is to arrange a sober ride instead of trying to calculate a safe departure time from drink count alone.
