Challenging the results of an Intoxilyzer test in a Florida DUI case involves scrutinizing the accuracy, administration, and maintenance of the device used. The Intoxilyzer is a common breath testing instrument used to measure blood alcohol concentration (BAC). Here’s how we can challenge the Intoxilyzer results:

​

1. Review Calibration and Maintenance Records

​

Calibration Procedures:

Regular Calibration: Intoxilyzer devices must be calibrated regularly to ensure accuracy. We obtain and review the calibration records for the specific Intoxilyzer used in your case. Calibration should be done according to manufacturer specifications and state regulations.

Calibration Certificate: We check if the device was calibrated within the required time frame before your test. Any lapses or discrepancies in calibration can undermine the reliability of the results.

​

Maintenance Records:

Service History: We review maintenance logs to confirm that the Intoxilyzer was properly serviced and maintained. Inadequate maintenance can lead to inaccuracies in test results.

​

2. Evaluate the Testing Procedure

​

Device Operation:

Officer Training: We will verify that the officer administering the test was properly trained and certified to use the Intoxilyzer. Incorrect operation or procedural errors by an untrained officer can affect the accuracy of the test.

Observation Period: We must ensure that the officer followed the required observation period (typically 20 minutes) before administering the test. This period is crucial to prevent interference from residual mouth alcohol, which can affect results.

​

Testing Protocol:

Test Administration: Confirm that the officer adhered to proper testing protocols, including the sequence of administering the test and ensuring that you did not eat, drink, or smoke shortly before the test.

​

3. Challenge the Accuracy of the Intoxilyzer

​

Device Reliability:

Scientific Accuracy: We review scientific literature and expert opinions regarding the accuracy and reliability of the Intoxilyzer model used. Some models may have known issues or limitations.

Device Model: We will check if the specific model of the Intoxilyzer used in your case has been subject to recalls or known reliability issues.

​

Breath Sample Analysis:

Breath Volume: The Intoxilyzer requires a sufficient volume of breath for an accurate reading. We will ensure that the sample provided was adequate and properly analyzed.

Mouth Alcohol Interference: We assess whether residual mouth alcohol could have affected the test results. Proper observation should mitigate this issue, but if the observation period was not followed, this could be a defense point.

​

4. Examine the Test Data and Documentation

​

Test Results:

Data Accuracy: We analyze the recorded test results for any inconsistencies or anomalies. Forensic experts can help interpret the data and identify any potential issues.

Documentation Errors: We must review all documentation related to the test for any errors or discrepancies in recording or reporting the results.

​

Chain of Custody:

Evidence Handling: Ensure that the chain of custody for the Intoxilyzer device and any related evidence was properly maintained. Any lapses in the chain of custody can affect the credibility of the test results.

​

5. Address Possible Medical Conditions

​

Medical Conditions:

Health Issues: Certain medical conditions, such as GERD (gastroesophageal reflux disease) or diabetes, can affect breath test results. In this situation, we will evidence of any relevant medical conditions that might have influenced the Intoxilyzer results.

​

6. Consult With Experts

​

Forensic Toxicologists:

Expert Analysis: In some cases we will hire a forensic toxicologist or a DUI expert to review the Intoxilyzer’s operation, calibration, and testing procedures. Expert testimony can help identify flaws and provide a credible challenge to the test results.

​

7. Legal and Procedural Challenges

​

Rights and Procedures:

Rights Violations: We are committed to ensuring that your legal rights were not violated during the arrest and testing process. Any procedural errors or violations of your rights can be leveraged in your defense.

​

Compliance with Regulations:

Regulatory Compliance: We will that all regulations and procedures for operating the Intoxilyzer and conducting breath tests were followed. Non-compliance with regulations can be used to challenge the validity of the test results.

 

Conclusion

​

To effectively challenge Intoxilyzer results in a Florida DUI case, we need to meticulously examine calibration and maintenance records, testing procedures, and the accuracy of the test data. Identifying any procedural errors, equipment issues, or medical conditions that could affect the results is crucial. We can help address the complexities of challenging breath test results.
