Virginia Blood Alcohol Content
If you have ever read any information about driving under the influence (DUI) or driving while intoxicated (DWI), then you have more than likely seen the acronym BAC. This stands for “blood alcohol content” or “blood alcohol concentration.”
Scientifically speaking, BAC is the concentration of alcohol in the blood. It is usually measured as mass per volume. For example, a BAC of .01 percent means 0.01 grams of alcohol per 100 grams of blood, or 0.1 grams per 1000 grams of blood. Blood alcohol content is measured in many different units across the globe.
In Virginia, .07 percent is the maximum allowable BAC a person may have when operating a motor vehicle or boat. At .08 BAC, a driver is presumed to be guilty of DUI.
There are two tests used to determine a driver’s BAC. The breath test is used unless it is not available or the driver is physically unable to submit a breath sample. Breath testing is performed using an Intox EC/IR II machine. Blood testing is done at a hospital.
If you have taken a breath test that resulted in a BAC of .08 percent or higher, you need to immediately hire an attorney to begin fighting the charges. Michael C. Tillotson is here to help. Our attorneys have years of experience of successfully handling DUI cases.
