Under Zero Tolerance, the threshold BAC for minors is…

• A. .00
• B. .01
• C. .02
• D. .04

Answer: (C)

Zero tolerance for minors means that driving with any alcohol is illegal, but the limit is set very low to deter underage drinking and driving. The commonly used threshold is 0.02% BAC because even small amounts of alcohol can affect a young driver’s abilities, and test results have some variability. Setting the limit at 0.02% provides a practical balance between enforceability and safety. A level of 0.04% would resemble typical adult DUI limits and isn’t aligned with the zero-tolerance approach for underage drivers. Levels like 0.00% or 0.01% would be too strict or impractical to enforce consistently, whereas 0.02% is the standard threshold in many jurisdictions.
