Challenging DUI Evidence: Breathalyzers, Blood Tests, and Field Sobriety Tests

,

Florida DUI defense lawyer

Driving Under the Influence (DUI) cases hinge on the evidence gathered by law enforcement to establish intoxication. Typically, this evidence includes results from breathalyzer tests, blood tests, and field sobriety tests. While these methods are widely used, they are not infallible. At the Law Office of Jeffrey H. Garland, P.A., we believe in a thorough examination of all evidence to ensure justice is served and that your rights are protected.

If you or a loved one is facing DUI charges, understanding how these tests work—and how they can be challenged—is essential. Jeffrey H. Garland, a skilled Port Saint Lucie criminal lawyer, has decades of experience defending clients in Florida DUI cases. Let’s take a closer look at these common methods of determining intoxication and how they can be contested in court.

Breathalyzer Tests: Questioning Accuracy

Breathalyzer tests are a popular tool for law enforcement to measure Blood Alcohol Content (BAC) on the spot. However, their reliability has been questioned time and again.

  1. Calibration Issues: Breathalyzers require regular calibration to ensure accurate readings. If the device isn’t properly maintained or calibrated, the results can be skewed. An experienced attorney can investigate whether the device used in your case met these standards.
  2. External Factors: Breathalyzers can be influenced by factors such as mouth alcohol from recent consumption, certain medications, or medical conditions like acid reflux. These can lead to falsely elevated BAC readings.
  3. Improper Use by Law Enforcement: The effectiveness of a breathalyzer also depends on proper usage. If an officer fails to administer the test correctly, the results may be invalid.

Blood Tests: Not Always the Gold Standard

Blood tests are often considered more accurate than breathalyzers. However, they are not immune to challenges in DUI cases.

  1. Chain of Custody Issues: Blood samples must follow a strict chain of custody to ensure their integrity. Any mishandling, contamination, or improper storage can compromise the evidence, making it inadmissible in court.
  2. Timing Matters: Blood tests are usually conducted after a suspect has been arrested, which means there’s often a delay between the time of driving and the test. This delay can result in misleading BAC levels due to alcohol absorption or elimination rates.
  3. Errors in Testing Procedures: Mistakes during the collection, transportation, or analysis of the blood sample can lead to inaccurate results. An experienced Florida DUI defense lawyer will scrutinize these procedures to uncover any errors.

Field Sobriety Tests: Subjective and Unreliable

Field sobriety tests are physical and cognitive exercises conducted by officers at the scene of a traffic stop. Common tests include the Walk-and-Turn, One-Leg Stand, and Horizontal Gaze Nystagmus (eye movement). However, these tests are highly subjective and can be challenged for several reasons:

  1. Physical or Medical Conditions: Many factors unrelated to intoxication—such as age, injury, fatigue, or certain medical conditions—can affect a person’s ability to perform these tests.
  2. Environmental Factors: Uneven surfaces, poor lighting, or adverse weather conditions can make these tests more difficult and less reliable as evidence of impairment.
  3. Officer Bias: The interpretation of field sobriety tests is subjective and may be influenced by an officer’s preconceived notions or lack of training.
