How to Challenge Breathalyzer Results in North Carolina

If you are one of the many people facing DWI charges after this holiday season, it is essential to understand your legal rights. If you took a breathalyzer test, a criminal defense attorney can help you determine the best legal defense in your case. Breathalyzer machines are not always accurate, and police officers are not always trained in how to use them correctly.

How to Challenge Breathalyzer Results in North Carolina

Driving under the influence (DWI) charges can have serious repercussions, not only impacting your driving record but also your personal and professional life. In North Carolina, if you have been arrested for a DWI, the breathalyzer test results can play a crucial role in your case. However, these results are not always infallible. Here are some ways to challenge breathalyzer results effectively, with insights from Arnold & Smith, PLLC.

Understand How Breathalyzer Tests Work

Before you challenge breathalyzer results, it is essential to grasp how these tests work. Breathalyzers measure the blood alcohol concentration (BAC) by analyzing the amount of alcohol in your breath. However, various factors can influence the accuracy of these tests, including:

• Calibration Errors: Breathalyzers need to be calibrated regularly. If calibration was not up to standard before your test, the results could be invalid.
• Mouth Alcohol: Any residual alcohol in your mouth, either from eating or drinking, can result in inaccurate readings.
• Medical Conditions: Certain medical conditions, like gastroesophageal reflux disease (GERD), can lead to falsely high BAC readings.

Knowing these variables can help you identify potential weaknesses in the evidence against you.

Challenge Officer Procedures

The procedure followed by the arresting officer during your DWI stop can significantly impact the case. Key points to focus on include:

• Probable Cause for Arrest: Did the officer have a reasonable belief that you were impaired? If there was no probable cause, the arrest itself may be unlawful.
• Administration of the Breathalyzer: Officers must follow specific protocols when administering breath tests. Any deviation from these protocols can lead to questions about the test’s validity.
• Observation Period: Officers are supposed to observe the suspect for a specific duration before administering the test to avoid inaccuracies. Failing to do so can be grounds for dismissal.

Seek Expert Testimony

In your defense, having an expert witness can be invaluable. A breathalyzer expert can provide insights into how certain factors may have affected the accuracy of your results. This can include discussions about device calibration, the science of breath alcohol measurement, and the credentials of the administering officer.

Consider Retesting Options

In some cases, you may request a blood test after a breathalyzer result. Blood tests are often considered more reliable. If you have undergone a blood test showing a lower BAC, this evidence can be used to challenge the breathalyzer results.

Look for Legal Defenses

Each DWI case is unique, and your legal team at Arnold & Smith, PLLC, can explore various defenses applicable to your situation. Common defenses include:

• Mistake of fact: Proving you had no intent to drive impaired due to a misunderstanding.
• Issues with the Breathalyzer device: Arguing that the device is faulty or unreliable.
• Constitutional violations: Any illegal stop or search that violates your rights can severely undermine the prosecution’s case.
