As many know, a breathalyzer is a machine that police officers and prosecutors often use to measure a person's blood alcohol level (BAC), when they feel a person is driving under the influence. How a breathalyzer works is, it takes a small sample of a person's breath and estimates how much alcohol is in the sample. Then the officers and prosecutors use these results to estimate how much alcohol is in a person's blood. In the state of Arizona, the legal limit of a person 21 years and older is a BAC of 0.08%. If a person is asked to perform a breath analysis test and the machine records the person's BAC as over the legal limit, then they will be arrested and prosecuted for DUI, and the breathalyzer results could become central to the prosecution's case.
In Arizona, there is only one approved breath alcohol testing device for DUI suspects - the Intoxilyzer 8000. This breath test machine works by utilizing an infrared light as its primary detection mechanism for breath alcohol concentration (BAC). As a result, it is important that there is not any radio frequency devices anywhere near the breath test machine while it is testing someone's breath for alcohol. If the device encounters radio frequencies, they could interfere with the test and drastically inflate the reported breath alcohol results!
