Breath Tests

When law enforcement officers suspect an individual of driving under the influence, they usually ask for a chemical test to assess the motorist’s blood alcohol content (BAC). A frequent method involves testing a sample of the driver’s breath. Police can utilize either a portable or a stationary machine to accomplish this. Before administering the test, the officer must supply the driver with a DL-26 form, which is also referred to as the “O’Connell warning.” This document acts as an implied consent notification. It is vital to understand that these testing machines possess various flaws. However, if a motorist consents to the procedure and their BAC reads 0.08 or greater, they will face a DUI charge. Operator blunders and technical glitches can occasionally lead to the dropping of drunk driving allegations.

Pennsylvania Breath Tests and How They Work

Let’s delve into how these breath tests operate within Pennsylvania. Typically, there are two distinct categories of breath tests utilized. If you are facing charges, a skilled Mercer DUI attorney can help you understand these mechanisms:

• Portable or preliminary breath tests (PBT): Law enforcement carries out these roadside assessments on motorists suspected of drunk driving. Frequently utilized machines include the BACmaster, AlcoCheck, and Intoxilyzer 500. The driver in question must blow into the handheld device, and the outcome might serve as probable cause for additional evaluations. Although the PBT shows numbers on an LCD monitor and lacks a printed record, the motorist is legally allowed to decline this roadside test. Furthermore, these specific results are not admissible as evidence in a courtroom.
• Evidential or stationary breath tests (EBT): These tests rely on larger, stationary devices situated inside police headquarters. Rejecting this official test can result in harsh penalties. PennDOT rules mandate taking multiple breath samples to guarantee the results are reliable. The data from these machines is printed and can be submitted as evidence during a trial. Authorized devices in Pennsylvania include Breathalyzer, DataMaster, and Alco test models. Consulting with a knowledgeable Mercer criminal lawyer is highly recommended if you are asked to submit to an EBT.

Errors in Breath Test Machines

The stationary breath test devices used to evaluate blood alcohol content are mostly viewed as precise. Still, a variety of complications can trigger inaccurate or false-positive outcomes. A qualified Mercer DUI attorney will often investigate the following frequent issues:

• Bugs or glitches in the software
• Environmental elements
• Radiofrequency interference (RFI) or electromagnetic interference (EMI)
• BAC overestimation caused by an assumed blood-breath partition ratio
• Inadequate or improper device maintenance
• The detection of non-ethyl alcohol compounds affecting the test numbers

Breath Test Operator Mistakes

Moreover, the precision of breath testing equipment depends heavily on the competence of the individuals operating them. Mishaps or negligence during the testing protocol might result in DUI cases being thrown out, as the blood alcohol content readings become inadmissible. A seasoned Mercer criminal lawyer knows to look for these potential blunders committed by law enforcement officials during testing:

• Testing performed by a police officer who lacks proper certification
• The evaluation taking place during the subject’s peak absorption phase
• Substantial discrepancies between the provided BAC samples
• Failing to gather the breath samples within the legally mandated time limit
• Ignoring the required, uninterrupted observation period
• Poor or incorrect calibration of the breath testing instrument

Breath Test Machines in DUI Cases

Throughout DUI cases in the Commonwealth of Pennsylvania, law enforcement primarily uses three machines to measure a person’s breath for alcohol intoxication: the DataMaster, the Intoxilyzer 5000, and the Intoxilyzer 8000. It is essential for a dedicated Mercer DUI attorney managing these cases to possess a deep comprehension of every single device. Each brand and model functions uniquely and features specific programming. Legal professionals must have the skill to cross-examine state troopers, local police, and other equipment operators concerning their qualifications and testing procedures to build an effective defense.

When defending individuals against DUI charges stemming from breath tests, a proficient Mercer criminal lawyer focuses on two primary elements. First, they scrutinize how the specific breath test device was calibrated. Crucial questions are raised regarding the exact date the calibration was finished, the identity of the technician responsible, and the level of training they received for that duty. The absolute accuracy of the machine’s calibration is paramount.

Secondly, an essential factor is the person operating the machine. Do they hold a valid license, or has it lapsed? Have they kept up with mandatory, continuous training on machine updates and proper usage? Did they execute the test on the suspect accurately? This component is incredibly important when forming a defense strategy. Operator mistakes substantially boost the likelihood of a charge being dismissed.

Luckily for individuals accused of a DUI, numerous breath test instruments utilized in Pennsylvania have been shown to be faulty. A State Supreme Court decision a few years back deemed certain readings invalid. Therefore, it is quite possible to have Blood Alcohol Concentration evidence from these machines suppressed or completely thrown out. However, authorities now frequently rely on blood tests rather than breath tests.
