Which statement correctly describes the under-21 BAC rule?

• A. There is no BAC threshold for under-21 drivers.
• B. A BAC of 0.08 or more may lead to a DWI.
• C. Only a BAC of exactly 0.02 leads to a DWI.
• D. A BAC of 0.02 or more may lead to a DWI.

Answer: (D)

Under-21 drivers face zero tolerance for alcohol, meaning any detectable amount can lead to a DWI. In New Hampshire, a BAC of 0.02 or higher may result in an underage DWI, which is why that option is the correct description of the rule. The 0.08 limit is the adult threshold, not the under-21 threshold. Saying only exactly 0.02 leads to a DWI is incorrect because higher BAC levels also count underage DWI. And there is indeed a BAC threshold for under-21 drivers; there isn’t a no-threshold rule.
