What Chemical Tests Are Used to Determine Blood Alcohol Concentration Under California’s Implied Consent Law
In California, the implied consent law means that a person who drives a car in the state and is lawfully arrested for DUI, is considered to have consented to chemical testing for blood alcohol content (BAC). Once a person is lawfully arrested for an Orange County DUI, there are three possible chemical tests that can be used. The California DUI implied consent law states that you have agreed to blood alcohol concentration testing through your breath, blood, or urine.
- Breath Test: Breath alcohol tests are conducted using a full sized breathalyzer machine. These full sized 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 (PAS) devices. Breath testing is the most common type of chemical test because it is the easiest, cheapest, and most convenient test for the police to perform.
- Blood Test: For this type of chemical test, a sample of blood is taken from a person arrested for DUI in California and the blood is sent to a lab to determine the blood alcohol concentration for that sample. If the officer suspects you were driving under the influence of drugs, you will likely be asked to submit to a blood test.
- Urine Test: 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.
