What is the legal blood alcohol concentration (BAC) limit for drivers under 21 in Indiana?

Answer: B — 0.02%

In Indiana, the legal Blood Alcohol Concentration (BAC) limit for drivers under 21 years of age is set at 0.02%. This limit reflects a zero-tolerance approach toward underage drinking and driving. It is significantly lower than the standard limit of 0.08% that applies to drivers who are 21 and older. This regulation is designed to discourage underage individuals from consuming any measurable amount of alcohol and operating a vehicle, thus promoting safety on the roads and reducing the risks associated with impaired driving. The other potential limits above 0.00% would allow for some alcohol presence, which contradicts the intent of the law aimed at protecting young, inexperienced drivers. Setting a BAC limit for this age group ensures that even trace amounts of alcohol, which could impair judgement and reaction times, are not tolerated. This reinforces the message that driving and drinking do not mix, especially for those who are not legally allowed to consume alcohol.
