Final answer:
Underage individuals with a BAC of .01 or more often face penalties such as license suspension, fines, and mandatory education or community service. These penalties are due to strict zero-tolerance laws influenced by the National Minimum Drinking Age Act of 1984.
Step-by-step explanation:
The mandatory penalty for an underage individual caught with a Blood Alcohol Concentration (BAC) of .01 or more can vary depending on the state. However, many states enforce strict zero-tolerance laws due to the National Minimum Drinking Age Act of 1984, which require states to set the minimum legal drinking age to 21 or risk losing a significant amount of federal highway funds.
Under these laws, underage offenders may face penalties such as driver's license suspension or revocation, fines, and mandatory alcohol education, counseling, or community service. The exact consequences depend on the individual state's legislation and the circumstances of the violation.
