What are the legal blood alcohol concentration (BAC) limits for drivers over 21 in Massachusetts?

In Massachusetts, the legal blood alcohol concentration (BAC) limit for drivers over 21 years of age is set at 0.08% BAC. This standard aligns with regulations in many other states across the United States, where 0.08% is commonly recognized as the threshold for driving under the influence (DUI) offenses.

At a BAC of 0.08%, there is significant impairment in a person's ability to operate a vehicle safely, leading to increased risks of accidents and injuries on the road. This legal limit is important for enforcing safe driving practices and holding individuals accountable for impaired driving. Understanding this limit is crucial for both compliance with the law and promoting public safety on the roads.
