Blood alcohol concentration (also known as BAC) is a measurement of the amount of alcohol in the blood stream and is typically used to convict a person of driving under the influence of alcohol. Blood alcohol concentration is typically measured by a breathalyzer test, but can also be measured by a direct blood test administered at a hospital.


While it is possible to have a drink or two before driving and still be under the legal 0.08% BAC limit in Mississippi, it largely depends on how quickly you drank, how long you have been drinking, whether or not you ate before you drank, whether you are male or female and how much you weigh.


For example, a 150 pound female who consumes 1 drink within a 1 hour time frame will have a BAC of 0.013% – well under the legal limit. However, if that same person were to have 2 drinks within a 1 hour time frame, her BAC would be 0.044%, and 3 drinks within the hour would raise her BAC close enough to the legal limit that she should not drive. A 190 pound man can consume 4 drinks within an hour and have a BAC of 0.069%, still under the legal limit.


If you think you may be too impaired to drive, don’t chance it. Have someone else drive you or call a cab. If you have been pulled over or arrested on the suspicion of driving under the influence, you need to contact a qualified DUI attorney as soon as possible.
