alcohol breath testing

Alcohol breath testing measures the amount of alcohol in a person's breath to estimate blood alcohol concentration (BAC). When you drink, alcohol enters your bloodstream and is eventually expelled through your lungs. A breathalyzer device collects a sample of your breath and analyzes it to determine how much alcohol is present. This measurement provides a legal estimate of your BAC, which can indicate if you're over the legal limit for activities like driving. The process is quick, non-invasive, and widely used by law enforcement to assess sobriety.
