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

In Massachusetts, the legal blood alcohol concentration (BAC) limit for drivers who are 21 years of age or older is set at 0.08%. This threshold is established to help ensure road safety by prohibiting drivers from operating a vehicle while impaired by alcohol. At or above this limit, individuals are considered legally impaired, and operating a vehicle can result in severe penalties, including fines, license suspension, and even imprisonment.

Understanding this limit is crucial for responsible drinking and driving behavior, as it provides a clear benchmark to evaluate whether a person’s BAC is within the legal limits. This standard applies not only to Massachusetts but is also common among many states in the United States, reflecting a national effort to combat drunk driving.
