What BAC level results in an under 21 individual being charged with DWI?

An under 21 individual can be charged with Driving While Impaired (DWI) at any measurable Blood Alcohol Concentration (BAC) level because many jurisdictions enforce a zero-tolerance policy for underage drinking and driving. This means that any detectable amount of alcohol can lead to legal penalties, as the law recognizes that individuals under the legal drinking age should not be consuming alcohol at all. This policy aims to reduce alcohol-related incidents among youth and promote public safety.

The other options suggest different BAC thresholds for underage individuals, but policies typically do not allow for any level of consumption for this age group. Therefore, the notion that an under 21 driver can be charged at any BAC effectively supports the zero-tolerance approach toward underage drinking and driving laws.
