Intoxication SignsQuestion 44 of 100
What is the relationship between BAC and observable signs of intoxication?
a.Observable signs always appear before a patron reaches 0.08% BAC
b.Observable signs are perfectly correlated with BAC for every person
c.BAC must be measured chemically — observation is unreliable
d.Observable signs vary by individual due to tolerance, body composition, and food, but trained observation is the legal standard under §25602
Explanation
BAC and observable impairment correlate broadly but imperfectly; tolerant drinkers may hide signs at 0.10%, while sensitive drinkers show signs at 0.04%. California law (§25602) does not require chemical proof — observation by a trained server is the lawful and practical standard. Servers must therefore err on the side of refusal when SCAN signs appear, regardless of the count of drinks the patron has consumed at your bar.
