What is Massachusetts' law regarding drivers under 21 and BAC?

In Massachusetts, the law established a 'zero-tolerance' policy for drivers under the age of 21. This means that any driver within this age group found to have a Blood Alcohol Concentration (BAC) of 0.02 or higher will face legal consequences. The rationale behind this stringent regulation is to deter underage drinking and driving, thereby enhancing road safety for all users.

Consequently, even a small amount of alcohol in the system can lead to penalties, which focus on preventing impaired driving among younger, less experienced drivers. This strict enforcement aligns with the overall goal of protecting public safety and promoting responsible driving behaviors among youth.
