When it comes down to it, DUI law centers around a driver's blood alcohol concentration. Blood alcohol concentration refers to the amount of ethyl alcohol in the bloodstream. When the concentration of alcohol gets too high, it hinders a driver's physical coordination, mental alertness, reaction time, critical thinking skills, and more. When this happens, there is a much greater chance of the driver causing a serious or fatal accident.
In California, it is illegal to drive with a blood alcohol concentration of .08% or more. For people under 21, it is a crime to drive with a BAC higher than .01%. Anyone found driving with a BAC level that reaches or exceeds the legal limit will be arrested and charged with DUI. In order to determine a driver's BAC, the arresting officer will conduct a breath or blood test. If the results of the test indicate the driver's BAC is above .08%, then he or she will be arrested on DUI charges. It is also important to note that if a driver is on probation for a DUI, a blood alcohol concentration of .01% can trigger a driver's license loss and a probation violation in court.
Breath Tests: Breath testing is the most common way police officers test BAC levels. To conduct a breath test, the officer, at the scene will instruct the driver to blow into a handheld device called a Preliminary Alcohol Screening device (PAS). This, unless a person is on probation, or under 21 is an optional test. A second breath test is necessary to comply with state law. Breath alcohol testing devices, the ALCOTEST 7110 or 7410 (Drager), calculates the driver's BAC by measuring the amount of breath alcohol in the deep lung region, which is believed to have a direct correlation with the amount of alcohol in the bloodstream.
Blood Tests: Blood testing is done either at the jail or a hospital, where a technician draws blood from the driver's arm for analysis. Although slightly less common than breath testing, blood testing is far more accurate, which can be a good thing if you're absolutely positive that your BAC is under .08%. However, if you aren't sure if you are over the limit, or depending on the time of your last drink you may want to opt for a breath test, as those are less accurate and more prone to error. With blood testing you also have the option of having a sample sent to an independent laboratory for retesting.
