BAC Evidence and DUI

Riverside DUI Attorney

BAC means Blood Alcohol Content or Blood Alcohol Concentration, and it is used to describe the amount of alcohol in the blood. At .08% BAC a person is considered to be legally drunk, and can be arrested for intoxicated driving. The principal ways to check for BAC are the breath test and the blood test. Police must follow procedures exactly for the results to be valid. If you have been arrested for DUI based on a test for BAC, you need to obtain strong and effective representation to defend against charges. DUI conviction can result in such penalties as incarceration, a stiff fine and license suspension.

Determining Blood Alcohol Content

The breath test does not directly measure BAC. Rather it tests of the concentration of alcohol in the breath. This is multiplied by a factor to estimate the BAC. The breath test can be unreliable if the machine has not been calibrated, or if the subject suffers from a physical condition, burps, or vomits. The result is also invalid if the police officer fails to turn off the police radio before administering.

The blood test is more reliable as it directly tests BAC. Still, blood testing must be done according to procedure to be valid. The technician must be properly certified. The technician may not use alcohol to clean the skin before taking the staple. The sample must be properly refrigerated and the chain of custody maintained.
