Field Sobriety Testing vs PBT

Every time an officer pulls someone over on suspicion of DUI, they will do everything they can to subject you to the non-scientific Field Sobriety Tests (FSTs). However, officers also have an ace up their sleeves to aid their cases against you, called the Preliminary Breath Test (PBT). There are many ways an officer can persuade you to blow into this device; remember, this is probably not their first day on the job, and they've spent time honing their skills to get the results they want. They've had considerable training and they know what works. 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.

While PBTs are so notoriously unreliable that they probably won't be seen by a jury, they will almost certainly be seen by a judge to boost the prosecution's case against you. 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. Remember that chemical testing is not the same as a PBT of FST, and you are required to submit to true chemical testing when asked by an officer. Refusal is grounds for a search warrant, 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

You will have a less effective defense if you choose an attorney who is not trained in the details of chemical testing . 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.
