Challenging DUI Charges in Rhode Island: How Attorney Zarrella Fights Faulty Field Sobriety Tests

When you're charged with driving under the influence (DUI) or refusal to submit to a chemical test in Rhode Island, the outcome of your case can hinge on the field sobriety tests. However, the reliability of Field Sobriety Tests (FSTs) and Drug Recognition Evaluations (DREs) is far from flawless.

Many Problems with Field Sobriety Testing in Rhode Island DUI Arrests

The National Highway Traffic Safety Administration (NHTSA) endorses three standardized tests used by law enforcement to evaluate impairment:

• Horizontal Gaze Nystagmus (HGN)
  
  

• Walk-and-Turn
  
  

• One-Leg Stand
  
  

Although these tests are supposed to follow strict administration protocols, they are often performed incorrectly or under conditions that compromise their reliability. Even with NHTSA-backed studies supporting them, these tests remain susceptible to officer error, environmental influences, misinterpretation, and a host of other issues.

As a top Rhode Island DUI defense attorney, Attorney Zarrella quickly identifies failures in the administration of field sobriety tests and the police's failure to follow established protocols. As a former member of law enforcement, Attorney Zarrella is uniquely equipped to spot these flaws and challenge them in court.

How Attorney Zarrella Uses SFST Certification to Your Advantage

Attorney Zarrella has undergone the same Standardized Field Sobriety Test (SFST) training that police officers receive and has attended numerous seminars on advanced DUI defense. This education, combined with 30 years of experience in DUI law, gives him a detailed understanding of how these tests should be administered—and how often they are not.

This training allows Attorney Zarrella to scrutinize DUI arrests for procedural errors. Whether it's poor administration, improper interpretation, or deviations from official guidelines, identifying these mistakes can lead to reduced charges or even a complete dismissal.

The Power of Cross-Examination in DUI Defense

One of the strongest tools in a DUI defense attorney's arsenal is cross-examination. Attorney Zarrella's in-depth knowledge of field sobriety test protocols allows him to ask precise questions that challenge the arresting officer's understanding and execution of the tests.

In many cases, Zarrella is able to present compelling evidence of officer mistakes before trial, opening the door to more favorable plea negotiations. When prosecutors realize that their evidence may not hold up in court, they are often more willing to reduce or dismiss charges.

Exposing Deviations from Standardized Test Protocols

The credibility of DUI tests relies on strict adherence to NHTSA's standards. Any deviation—such as incorrect positioning of the HGN stimulus or improper timing during administration—can lead to false signs of impairment.

Attorney Zarrella knows exactly what to look for. For instance, if the officer held the HGN stimulus too close or failed to keep it level with the suspect's eyes, the results could be invalid. Through effective cross-examination, Zarrella brings these missteps to light, weakening the prosecution's case.

Environmental Factors That Skew Field Sobriety Results

In Rhode Island, weather and road conditions often create poor environments for field sobriety testing. These tests are supposed to be conducted on flat, well-lit surfaces, but often occur:

• On sloped or uneven pavement
  
  

• In heavy rain or snow
  
  

• In dim lighting or at night
  
  

• Near passing traffic or loud background noise
  
  

• With defendants who are older or overweight
  
  

• With vague or improper instructions
  
  

• Using non-standardized tests
  
  

• Producing inaccurate test results
  
  

All of these conditions can affect balance and coordination, making a sober person appear impaired. Attorney Zarrella uses these facts to cast doubt on the results and argue that the testing environment unfairly impacted your performance.

Questioning the Officer's Training and Instructions

Not all officers in Rhode Island receive extensive training in SFSTs. Even when they do, inconsistent practice and vague instructions can render the tests unreliable.

For example, if an officer gives unclear directions during the One-Leg Stand test, it can confuse a driver—even one who is completely sober. Attorney Zarrella cross-examines officers about their training and the exact instructions they gave to highlight these potential issues.

Today, many DUI arrests are recorded on police body cams. These videos are often invaluable in showing how officers failed to properly administer or score the SFSTs. Attorney Zarrella reviews this footage closely to identify and expose such errors.

Medical Conditions Often Mistaken for Impairment

Field sobriety tests don't account for individuals with medical issues. Conditions such as vertigo, neurological disorders, diabetes or physical injuries can affect a person's balance, coordination, or speech.

If an officer overlooks or misinterprets these symptoms, they may wrongfully conclude that a person is impaired. Attorney Zarrella raises these concerns during testimony and questions whether the officer properly considered a medical explanation.

Even Law Enforcement Acknowledges These Tests Aren't Perfect
