Jacksonville DUI Lawyer

Even if the stop is legal, the decision to call for a BAC-level test may not be. A Jacksonville officer must still have probable cause to issue the test. If a driver is slurring their speech or stumbling, that can qualify. Open containers in the vehicle can make a test legitimate. But, there has to be a reason, and it bears noting that the officer’s burden of proof at this level will be a little bit higher than it was when making the stop.

Perhaps the officer’s probable cause comes from the driver failing a field test—those drills where the police make a person extend their arm and touch their nose and do other activities to test coordination. These tests must be recorded by the officer’s dashboard video and are subject to review by defense counsel.

What if a person had to undertake the test in rainy conditions or on an uneven surface? What if the person simply struggles with their coordination? The decision as to whether someone “failed” this test is highly subjective, and a Jacksonville DUI defense attorney can contest the officer’s basis for probable cause.

Let’s say both the stop and the decision to take the driver’s BAC level were legitimate. There are still options for the defense. The BAC level that the breathalyzer machine may show isn’t as infallible as some people think. There are a lot of reasons a breath test can come back inaccurately high. 

Here are just a few reasons why a breath test may be off: 

• The driver consumed sugar or bread along with their alcohol. Is it really difficult to imagine having cake with a glass of wine? Or pretzels along with a beer? Those food products can result in deceptively high BAC levels. 
• The driver consumes certain types of medication. It can be something as basic as mouthwash that results in a non-intoxicated driver being wrongly charged. 
• The driver has a medical condition that the breathalyzer misreads. Diabetes, acid reflux, and heart problems are all common. They also can lead to deceptively high BAC levels. 

Monroe Law reviews all this and more with our clients so that we can pursue all avenues of defense. Remember, it is only necessary to raise a reasonable doubt in the minds of a judge or jury to get someone acquitted of a DUI charge in Jacksonville. 

A blood sample is no more perfect than a breath test. To begin with, the needle that draws the blood was quite likely sterilized in alcohol. If this wasn’t done properly, it’s not hard to see how this could lead to a false high on the BAC level.

The sample must also be stored according to strictly defined protocols, lest the blood ferment too long and the reading be inaccurate. Everyone who handles the sample must document it. It is the responsibility of the police department to produce the necessary documentation that their testing meets all legal requirements.
