Breath Tests

When a police officer in Clarion suspects someone of driving under the influence (DUI), they will typically request a chemical test to determine the driver’s blood alcohol content (BAC). One of the most commonly used methods involves analyzing a sample of the driver’s breath. Officers may use either a portable or stationary device for this purpose. Before the test is administered, the driver is provided with a DL-26 form—commonly known as the “O’Connell warning”—which acts as an implied consent statement. It’s important to understand that these devices are not infallible and can sometimes produce inaccurate results.

If a driver agrees to the test and their BAC measures at 0.08 or higher, they will face DUI charges. However, errors made by device operators or technical malfunctions can sometimes lead to the dismissal of drunk driving charges. If you’re navigating this situation, working with a knowledgeable Clarion DUI lawyer can make a significant difference in your case outcome.

Pennsylvania Breath Tests and How They Work

Understanding the mechanics of breath testing in Pennsylvania is essential for anyone facing DUI charges in Clarion County. Two primary types of breath tests are commonly used:

Portable or Preliminary Breath Tests (PBT)

These roadside tests are conducted by law enforcement officers on drivers suspected of impairment. Commonly used devices include the Intoxilyzer 500, AlcoCheck, and BACmaster. The driver is asked to blow into the portable device, and the results may serve as probable cause for further testing. Key points to note:

• Results are displayed on an LCD screen and are not printed out
• Drivers have the right to refuse this test
• PBT results are not admissible in court

Evidential or Stationary Breath Tests (EBT)

These tests are conducted using larger machines located at police stations. Refusing to take this test can result in severe penalties. Under PennDOT regulations, multiple breath samples are required to ensure reliability. Unlike PBTs, the results of EBTs are printed out and can be used as evidence in court. Approved machines used in Pennsylvania include the Alco Test, DataMaster, and various Breathalyzer models.

If you’ve been subjected to either type of test, a skilled Clarion traffic ticket attorney at Logue Law Group can help you understand your options and rights.

Errors in Breath Test Machines

While breath test machines are generally considered accurate tools for measuring blood alcohol content, various issues can produce false positive results. Being aware of these potential errors is critical when building a defense. Common problems include:

• Software glitches or bugs within the device’s programming
• Environmental factors that may affect the machine’s accuracy
• Electromagnetic interference (EMI) or radiofrequency interference (RFI)
• Overestimation of BAC due to an assumed blood-breath partition ratio
• Improper maintenance of the testing device
• Inclusion of non-ethyl alcohol substances in the test results, leading to skewed readings

Understanding these flaws is where an experienced Clarion DUI lawyer becomes an invaluable asset—identifying errors that could result in reduced or dismissed charges.

Breath Test Operator Mistakes

Beyond machine-related errors, the accuracy of breath test results depends heavily on the expertise of the person operating the device. Mistakes made during the testing process can render BAC readings inadmissible as evidence, potentially leading to the dismissal of DUI charges. Common operator errors include:

• Breath test administered by a non-certified police officer
• Test conducted during the driver’s peak absorption period
• Significant variation between BAC samples
• Failure to collect breath samples within the required time frame
• Neglecting to conduct the mandatory observation period
• Inadequate calibration of the breath test machine prior to use

When operator errors are identified by a seasoned Clarion traffic ticket attorney, they can significantly strengthen your defense and challenge the validity of the test results.

Breath Test Machines in DUI Cases

In DUI cases across Pennsylvania, three machines are primarily used to assess a driver’s breath for alcohol impairment: the Intoxilyzer 8000, the DataMaster, and the Intoxilyzer 5000. Each device operates differently and carries unique programming, which is why criminal defense attorneys at Logue Law Group maintain a thorough understanding of each machine.

An experienced Clarion DUI lawyer from our team will scrutinize law enforcement officers, state troopers, and machine operators regarding their methods and qualifications. When defending clients against breath test-based DUI charges, our attorneys focus on two main aspects:

Machine Calibration

Questions about calibration are central to any breath test defense. When was the machine last calibrated? Who performed the calibration? Were they adequately trained to do so? The accuracy of machine calibration is of the utmost importance, as any inconsistencies here can cast doubt on the reliability of the results.

Machine Operator Qualifications

The second key consideration is the operator’s credentials. Is their license current or has it expired? Have they kept up with ongoing training on machine advancements? Did they follow proper procedure during the test? Operator error is one of the most powerful tools for getting a DUI case dismissed, and an experienced Clarion traffic ticket attorney knows exactly how to leverage it.

Fortunately for defendants in Pennsylvania, several breath test machines have been found to be defective. A State Supreme Court ruling rendered some of these machines unreliable, making it relatively achievable to have BAC readings suppressed or dismissed entirely. That said, blood tests are more commonly used in DUI cases than breath tests, adding another layer of complexity to these proceedings.
