Seeing blue lights in the rearview mirror can make anyone’s heart race. If that stop ends in a DUI arrest based on a breath test result, you might feel like the you no longer have any options. While this moment feels overwhelming, you must have a thoughtful look at the procedure before the results are accepted as fact.
Essential components of the observation period
The breath test is a technical process. It serves as the state’s primary evidence, but it requires strict adherence to Maryland protocols. The process of checking these results is not just about the number on the screen, but about the 20 minutes of police conduct that happened before you ever blew into the machine. When you review your stop, the legal analysis centers on these crucial components:
- The 20-minute observation rule: The officer must remain in close proximity for at least 20 minutes before the test. This ensures the machine measures deep lung air rather than mouth alcohol. If the officer’s attention was so diverted, the “observation” may be challenged.
- Interruptions and restarts: The clock must restart if you vomit or regurgitate. These actions bring stomach acid or alcohol back into the mouth, which can create a falsely high reading. A failure to restart the clock can make the results scientifically unreliable.
- Prohibited actions: The officer must ensure you do not smoke, eat or drink anything during the wait. Even a small piece of gum or a sip of water can contaminate the sample and lead to inaccurate data.
Your defense strategy provides the essential clarity needed to move forward confidently.
Securing your future
The legal paperwork and procedural logs in a DUI case lock in the state’s version of events. However, starting with an honest and detailed review of the police conduct builds the foundation for a strong defense. This allows you to focus on protecting your license and your reputation.
