What does a "brAC" reading signify?

A "brAC" reading signifies Breath Alcohol Concentration. This term refers specifically to the measurement of the amount of alcohol present in a person's breath. The Intoxilyzer 9000, which is commonly used in the field for breath analysis, calculates this concentration to assist law enforcement in determining an individual's blood alcohol level, which is critical for assessing impairment under legal standards.

The brAC is derived from the principle that the amount of alcohol in the breath can be correlated to the amount in the blood. Since breath testing devices are non-invasive and provide immediate results, they are an integral part of DUI enforcement and contribute significantly to road safety measures.

Understanding brAC is crucial for those involved in breath testing, as it provides a clear indication of alcohol impairment and is foundational to many legal proceedings related to driving under the influence.
