Got A DUI in Paradise Valley? Chemical Testing Can Be Ineffective

Arizona Attorney Certified in Chemical Testing

More often than not, chemical testing has played an important role in the prosecution’s case against you.

There simply isn’t a better option for your defense.

Field Sobriety Testing vs PBT

You’ve surely seen videos, or even heard personal anecdotes from friends or family of an officer attempting to put people through a parade of testing, known as the Field Sobriety Test (FST). As a backup, an officer will often try to employ a Preliminary Breath Test (PBT). The officer has many different tricks at his disposal to persuade a driver to blow into this device; you are almost certainly not the first person they’ve pulled over on suspicion of driving under the influence. In short, they’ve had practice and have sharpened their skills. They will often say things like “This test is inadmissible in court, so it can’t be used against you”, or, “If you just blow into this, we can get you on your way”. These are deceptive half-truths to persuade you to blow.

It’s true: PBTs are so often unreliable that a jury won’t even see them. However, often the judge will see this evidence as presented by the prosecution. These are used to confirm a suspicion of your DUI, but they are not accurate diagnostic tools. Further, drivers can refuse PBTs, so it’s critical to know your rights so you know what tests you do and do not have to take.

Authorities will only rely on diagnostic tools used to analyze breath, blood, and urine when evaluating drug or alcohol levels. You are required to submit to true chemical testing when asked by an officer. Refusal is grounds for a warrant being placed for your arrest, and immediate suspension of your driver’s license.

Blood and Breath

Attorney Craig Rosenstein is certified in both chemical testing and field sobriety tests. He understands protocol, and knows the potential downsides of different methods of analysis. Because he is trained on breathalyzers like the Intoxilyzer 8000, and also has certifications for blood and urine testing, he knows exactly how the tests should be conducted and he knows how to interpret and understand the results. He is also aware of the data not taken into account by the tests, such as:

  • Drinking pattern, if any
  • Health conditions like GERD or diabetes
  • Foods consumed
  • Elevated body temperature
  • Prescription medication interactions
  • Possible sample contaminations
  • And many other variables

Not having an attorney who is trained in chemical testing and analysis means having a less effective defense against your DUI charges . Furthermore, if your attorney does not understand how the tests are performed, what checklists need to be followed, or the opportunities for false-positives and sample contamination, your defense will simply not be as strong as it could (and probably needs) to be.
