What chemical tests are used to determine blood alcohol concentration through the California DUI implied consent law?
Once a person driving a car in California is lawfully arrested for DUI there are three possible chemical tests that they must utilize. The California DUI implied consent law states that you have agreed to blood alcohol concentration testing through your blood, breath or urine. Blood alcohol testing through urine analysis has been shown to be somewhat inaccurate so urine testing for blood alcohol content is only used if breath alcohol testing and blood alcohol testing measures are not available. When dealing with the California implied consent law, breath alcohol tests are tested using a full sized breathalyzer machine. These full sizes machines are the only breath alcohol testing measure that can be used in California DUI court. The full sized breathalyzer uses a more accurate scientific method than the hand held breathalyzer units called Preliminary Alcohol Screening devices. The third type of blood alcohol testing that applies to the California implied consent law is blood analysis.
