Blood Alcohol Content (BAC)

The central issue in almost every DWI or DUI case is whether your blood alcohol content (BAC) is equal to or greater than the statutory minimum. In other words, if your blood alcohol content is above this minimum, you are presumed to be legally intoxicated and subject to being charged with DUI / DWI. In the United States, every state of which I am aware has a DUI / DWI statute that sets the legal BAC threshold at .08 percent.

What exactly is your BAC? Simply put, it is the amount of alcohol in your blood. A BAC test actually measures the weight of alcohol in a certain volume of your blood, expressed as a percentage. Generally, the greater the level of alcohol in your blood, the more your driving will be impaired. In fact, although most state DWI / DUI laws provide that a blood alcohol content of .08 percent is the level at which you are considered legally intoxicated, some studies conclude that a blood alcohol content as low as .02 affects your ability to drive and increases the likelihood of an accident. The probability of a crash begins to increase significantly at a blood alcohol content of .05 percent and climbs rapidly above .08 percent.
