Your Body Weight and Your BAC (Part A)

If you are pulled over under the suspicion of a Virginia DUI, then one of the things that an officer will do is test your blood alcohol content (BAC) level. They may do this by breathalyzer test at the scene of the incident, or by blood test once you have been arrested. If your BAC level is measured at .08 or above, you will be charged with a Virginia DUI. However, with the help of a Virginia DUI attorney, you may fight your DUI charge.

One way you can fight your DUI charge is by challenging the evidence that the state has against you. There are factors in BAC readings that might affect the results of a test, such as your body weight, and the rate that alcohol is absorbed into your body's bloodstream. By raising the question of whether or not your BAC test was accurate, an attorney may convince a judge to dismiss your DUI charges.

 

How does my body weight affect a BAC reading?


Generally, the less you weigh, the more you will be affected by the consumption of alcohol. In other words, a lower body weight makes for a higher concentration of alcohol in the body. This is because the BAC in your body is measured as the total amount of alcohol divided by your total amount of body water. Therefore, someone who weighs less will generally have a lower amount of body water, which will have less of a dilutive effect on the alcohol in your system.

One of the other factors in BAC readings is a person's body fat percentage. If two people weigh the same, but one has more body fat while the other has more lean muscle tissue, then the person with more body fat will maintain a higher concentration of alcohol. This is because fatty tissue does not contain as much water as lean muscle tissue, which means the alcohol will affect a person with a higher concentration of body fat more than the same amount of alcohol might affect a person with more muscle. This may also ultimately result in a higher BAC reading for a person with more body fat.

To know more about the determining factors in BAC readings, you can contact a Virginia DUI attorney. An expert attorney can explain the debatable factors in BAC readings.
