Breath & Blood Tests: An Overview
Information from DUI Defense Attorneys in San Diego
When the police pull over a possible suspect driving under the influence, there must be reasonable cause to do so. The officer will likely seek to measure the driver’s level of intoxication through the use of a breath or blood test. If a driver is under 21 years of age, their blood alcohol content (BAC) cannot exceed .01%. If the driver is over 21 years of age, their BAC cannot exceed .08%. Those who hold commercial licenses are restricted to a BAC level of .04%.
Evidence from Breath Tests
To measure the driver’s BAC on the scene, the officer may administer a breath test with a breathalyzer. There have been countless cases in which the breath test has faulty results. There could be an inaccurate reading due to faulty or improperly calibrated equipment, a test incorrectly administered, or a medical condition which alters test results. Our legal team has a full understanding of the science behind the tests, and will review all aspects of your breath or blood test evidence to determine if errors have been made.
Evidence from Blood Tests
A blood test can be taken at the police station or hospital. If you are certain your blood alcohol content is below .08%, the blood test can be more accurate at a hospital, and you also have the option of having a blood sample sent to an independent lab for testing. There have been countless cases of errors in blood testing. Medical doctors are aware that test results can be inaccurate and frequently re-test for illnesses and diseases. There is no testing system that is completely infallible.
