What do the results mean?
Blood alcohol level results may be given in different ways, including percentage of blood alcohol content (BAC). Typical results are below.
Sober: 0.0 percent BAC
Legally intoxicated: .08 percent BAC
Very impaired: .08–0.40 percent BAC. At this blood alcohol level, you may have difficulty walking and speaking. Other symptoms may include confusion, nausea, and drowsiness.
At risk for serious complications: Above .40 percent BAC. At this blood alcohol level, you may be at risk for coma or death.
The timing of this test can affect the accuracy of the results. A blood alcohol test is only accurate within 6–12 hours after your last drink. If you have questions or concerns about your results, you may want to talk to a health care provider and/or a lawyer.
