What is the maximum allowable BAC for drivers over 21 in Massachusetts?

In Massachusetts, the maximum allowable blood alcohol concentration (BAC) for drivers over the age of 21 is set at 0.08%. This standard aligns with the national legal limit for driving under the influence, which is recognized across many states. A BAC of 0.08% indicates a level of impairment that significantly affects a person's ability to operate a vehicle safely, as it can lead to reduced coordination, slower reaction times, and impaired judgment.

Maintaining a BAC at or below this limit is crucial for ensuring road safety and minimizing the risks of accidents. States enforce strict penalties for those caught driving with a BAC above this limit, reflecting the seriousness with which authorities treat impaired driving. The other options reflect BAC levels that are either too low or not applicable to the legal limits established for adult drivers in Massachusetts.
