What is the Legal Limit for Alcohol Consumption in MA?

In Massachusetts, the legal limit for alcohol is .08 Blood Alcohol Content (BAC) for those over 21, and .02 for those under 21 (aka zero tolerance).

You are generally better off not taking the breathalyzer if asked to do so by the police. The fact that you refuse the breath test/breathalyzer test cannot be noted or used against you in court. If you've been charged with driving while over the legal limit, you need to consult with a lawyer.

If you've been arrested and did take and fail the breathalyzer test, there are a number of things we can do to fight your OUI charge. Even the police will acknowledge that a breathalyzer is only accurate to +/- .02 BAC.

BAC Analysis

BAC vs. BrAC

Most BAC is levels are calculated by a breath test machine, commonly known as a breathalyzer. The breathalyzer calculates breath alcohol content (BrAC) which is translated into an approximately equivalent blood alcohol level (BAC). There are often problems with these calculations, since they are based on average lung capacity and biology, and not everyone is "average".
