What Is the Legal Limit for Alcohol Consumption in Massachusetts?
In Massachusetts, it is illegal to operate a motor vehicle with a Blood Alcohol Content (BAC) of .08% or greater. For individuals under the age of 21, the Massachusetts RMV will suspend your license for operating a motor vehicle with a .02% BAC or higher. Operators of a commercial driver’s license (CDL) face a CDL suspension for operating a motor vehicle with a BAC of at least .04%.”
How to Calculate Blood Alcohol Content?
The most commonly used formula to calculate Blood Alcohol Content is:
%BAC = (A x 5.14/W x r) – .015 x H, where
- “A” is the number of liquid ounces of alcohol consumed. For example, the standard 5% beer would be .60 (12 x 0.05)
- “W” is the person’s weight in pounds
- “r” is the distribution ratio (.66 for women, and .73 for men)
- “H” is the number of hours in which the alcohol was consumed
However, this formula is not 100% accurate when used to calculate Blood Alcohol Content. Several complex factors must be taken into consideration to accurately calculate Blood Alcohol Content, such as physical and emotional health, as well as the consumption of food.
