San Joaquin DUI Lawyer

The legal limit for blood-alcohol content (BAC) level while driving in the state of California is 0.8%. When a person takes a breath test or blood test and sees their BAC come in at that level or higher, it can feel like the walls are closing in on them. The face the potential for losing a driver’s license, steep fines, and, depending on their prior record, perhaps even jail time. But what many people don’t realize is that the BAC test is far from infallible. And an experienced San Joaquin DUI lawyer can do the investigative work into finding out just how accurate the test was.

How to Challenge a DUI Test in California

There are a large number of factors that can impact a BAC test, leading to a falsely high reading. Quite a few of these factors are everyday things that include basic foods, standard medications, and normal human error. 

Challenging the Breath Test

There are protocols to handling breathalyzer equipment. The machines must be recalibrated at the police department on a regular basis, and that recalibration must be documented. Each officer that uses the equipment must have had formal training in the process. And even if you allow, that these two things are in order, the test itself can still be skewed by food ingested or medications taken. 

Bread is something that can trigger a falsely high reading on a breath test. So can sugar. How often, when people may be having a drink or two, do they also eat something that involves bread or sugar? It can be anything from pretzels with beer to cake with champagne. All of which can cause an otherwise responsible drinker to appear intoxicated when they take the breath test. 

Different medications and health conditions can have the same effect. A person who has chronic acid reflux can have that show up in a falsely high BAC level. Even something as basic as mouthwash can make a driver appear more to have consumed more alcohol than they actually did.

Challenging the Blood Test

The problems associated with a blood test are different than those of a breath test, but they are no less real. An obvious one is that the needle used to draw the blood is typically cleaned with alcohol. Suffice it to say, if the cleaning is not done properly, the effects of that alcohol could show up in the test. 

Then the blood sample itself has to be properly handled. Blood that is stored for an inappropriate amount of time can start to ferment, which means that it will show higher BAC levels. As a way of monitoring this and maintain security around the sample, blood tests have strict chain of custody requirements. Every person that handles the sample must be accounted for and every step the sample takes must be documented. Failure to follow chain of custody is a serious violation and can invalidate an otherwise valid test.
