BAC Basics

Everyone has probably heard of a DWI, but not everyone is aware of how “intoxication” is legally defined.  Basically, it comes down to your BAC, or blood alcohol content level.  Your BAC is what law enforcement officials use to determine your level of intoxication and determine if you need to be issued a DWI.  By understanding what your BAC is and how BAC is measured, you may be able to better identify instances in which you may have been wrongly accused of drunk driving.

What is my BAC?

Your blood alcohol content level measures the amount of alcohol that is in your body.  The most common type of sobriety test that law enforcement officials administer to determine BAC is the breathalyzer test, but there is also:

  • blood sample test – 100 milligrams
  • urine test – 67 milliliters
If your BAC is measured at over 0.08%, you are considered legally “intoxicated” and may pose a danger to yourself or others.  If you happen to be operating a vehicle at the time of a blood alcohol test and your BAC is registered above .08%, you may be charged with DWI and face legal consequences.  The state of Texas handles DWI convictions very harshly, and those convicted may face heavy monetary fines, in addition to serving probation or even jail time.
