DUI Testing in Florida: What You Need to Know

Driving under the influence (DUI) charges in Florida are serious offenses that can lead to significant legal and personal consequences. If you’ve been charged with a DUI, the results of your intoxication test will likely play a critical role in your case. However, these tests are not infallible, and their accuracy can be challenged under certain circumstances. At Chang & Pyles, we know DUI defense and know how to scrutinize the methods and results used in DUI cases to protect our clients' rights.


Types of DUI Tests Used in Florida

Law enforcement in Florida typically relies on three types of tests to confirm intoxication:


Breath Tests: Often administered via a breathalyzer, this test measures the amount of alcohol in your breath to estimate your blood alcohol concentration (BAC).


Blood Tests: Used to determine the exact level of alcohol or drugs in your bloodstream. This test is usually conducted in a medical setting.

Field Sobriety Tests: Physical and cognitive exercises, such as walking in a straight line or standing on one leg, are used to assess impairment on the spot.


Each of these methods has its vulnerabilities, and a skilled defense attorney can examine whether they were administered correctly and if the results are reliable.


Common Issues with DUI Testing

While DUI tests are a key element in building a case against a defendant, they are not without flaws. Here are some common issues that can arise:

Probable Cause for Testing: The police must have valid probable cause to initiate a DUI test. If this is not established, your attorney may challenge the legitimacy of the test.


Improper Test Administration: Breathalyzer tests and field sobriety tests must follow strict protocols. Errors in administering these tests can lead to inaccurate results.


Lab Errors and Margin of Error: Blood tests are often seen as the most accurate, but they are not immune to human error. Labs handling blood samples may have prior issues with reliability, or results may fall within the margin of error, raising questions about their validity.


Medical Conditions or External Factors: Conditions such as acid reflux or medications can interfere with breathalyzer results, while environmental factors like poor lighting or uneven surfaces can skew field sobriety test outcomes.
