What is Blood Alcohol Content (BAC)?

Blood Alcohol Content, or Blood Alcohol Concentration, refers to the amount of alcohol per volume of blood in a person’s body. BAC is typically expressed as a percentage of total blood volume. For example, the legal BAC limit in North Carolina is .08%. If you are pulled over on suspicion of drunk driving, an officer may ask you to take a blood or Breathalyzer test to measure your BAC. Unfortunately these tests sometimes yield inaccurate results which may cause you to be wrongly arrested for DWI.

If you have been charged with DWI because of the results of a breath or blood test, contact Raleigh DWI defense lawyer Jim Black today at 919-600-4609 to discuss your legal options.


"Jim, I just wanted to thank you again for everything you did for me. I am very happy about the outcome and would recommend you to anyone and everyone who has a DUI case. Two things that stuck out the most is your patience and honesty, you wanted the best for me and that was obvious."
