Blood Alcohol Testing and DUI

Blood alcohol testing is what California law enforcement agencies use to determine the amount of alcohol in your blood, also called your blood alcohol concentration (BAC). In California the legal limit for your BAC is .08%. If your BAC is found to be .08% or higher, then you will be charged with DUI (driving under the influence).

The method and means of blood alcohol testing that was used to determine your DUI charges will likely have a great impact your DUI case. San Diego DUI lawyer James N. Dicks knows what errors to look for in blood testing and can build a successful defense based on this. There are a number of factors which may affect your blood alcohol testing and whether the results are valid in a court of law:

• Operator error
• An improperly calibrated machine
• Test results which are handled improperly
• Mechanical error

In addition, your unique weight, metabolism and body temperature may affect your BAC results. Using this and other information, attorney James Dicks may be able to have your blood alcohol evidence suppressed during your DUI trial.

Types of Blood Alcohol Tests

A person’s blood alcohol level may be determined using blood, breath or urine. Blood and breath are the most common mediums for testing, but urine is used when blood or breath testing is not available. A breathalyzer or breath testing machine will determine the estimated BAC by testing a person’s breath. Blood alcohol testing and urine testing are chemical tests usually performed in a lab to determine the amount of alcohol present.

If you have submitted to blood alcohol testing, we will investigate and review every aspect of the circumstances leading up to and during your actual testing and the test evaluation, to determine whether everything was conducted properly. DUI attorney James Dicks has the experience to recognize an error when he sees it and build a defense.
