Understanding Breathalyzers and How They Work

Breathalyzers, also known as breath alcohol testers (BATs), are devices used by law enforcement to estimate a person’s blood alcohol concentration (BAC) based on the amount of alcohol present in their breath. The underlying principle relies on Henry’s Law, which states that at a constant temperature, the amount of a gas dissolved in a liquid is proportional to the partial pressure of that gas above the liquid. In this context, the alcohol in your blood equilibrates with the air in your lungs, and the breathalyzer measures the alcohol concentration in your exhaled breath to estimate the BAC.

There are primarily two types of breathalyzers used by law enforcement:

• Infrared (IR) Spectrophotometry: These devices measure the absorption of infrared light by alcohol molecules in the breath sample. Alcohol absorbs infrared light at specific wavelengths, and the amount of absorption is directly proportional to the alcohol concentration.
• Fuel Cell Technology: Fuel cell breathalyzers use a chemical reaction to measure the alcohol in the breath. The alcohol is oxidized at an electrode, producing an electrical current that is proportional to the alcohol concentration.

Both types of breathalyzers are subject to various sources of error, which can lead to inaccurate BAC readings. Understanding these potential errors is the first step in challenging a breathalyzer result.

Common Misconceptions about “Beating” a Breathalyzer

Before delving into potential strategies for challenging breathalyzer results, it’s crucial to dispel some common myths and misconceptions about “beating” the test. Many purported methods circulating online are ineffective, dangerous, or outright illegal. Here’s a breakdown of why these tactics typically fail:

• Penny in the Mouth: The myth that placing a copper penny in your mouth will affect the breathalyzer reading is false. The amount of copper is insufficient to produce any noticeable chemical reaction or interference.
• Breath Mints and Mouthwash: While breath mints and mouthwash might temporarily mask the odor of alcohol, they often contain alcohol themselves. This can actually increase the BAC reading, albeit temporarily. Furthermore, any masking effect is short-lived and easily detectable by law enforcement.
• Eating Food: Eating food might slow the absorption of alcohol into the bloodstream, but it won’t eliminate alcohol already present in your system. Breathalyzers measure the alcohol in your breath, which is a direct result of the alcohol in your blood.
• Hyperventilating: Intentionally hyperventilating in an attempt to lower the breathalyzer reading is generally ineffective and can even backfire. While rapid breathing might temporarily decrease the concentration of alcohol in your breath, the breathalyzer is designed to detect inconsistencies in breathing patterns. Furthermore, hyperventilation can lead to dizziness and other health problems.
• Burping or Vomiting: Burping or vomiting immediately before a breathalyzer test might introduce alcohol from the stomach into the mouth, potentially increasing the BAC reading. However, officers are typically trained to observe individuals for a specific period (usually 15-20 minutes) before administering the test to avoid this issue.

Attempting to manipulate or deceive a breathalyzer can have serious legal consequences, including additional charges and penalties. It’s far more prudent to understand the potential sources of error in breathalyzer tests and to consult with an attorney if you believe the results are inaccurate.

Potential Strategies for Challenging Breathalyzer Results (with Legal Counsel)

Challenging a breathalyzer result requires a thorough understanding of the law, the science behind breathalyzers, and the specific circumstances of your case. It’s essential to work with a qualified DUI attorney who can evaluate the evidence and determine the best course of action. Here are some potential strategies that an attorney might explore:

1. Challenging the Accuracy and Reliability of the Breathalyzer Device

• Calibration and Maintenance Records: Breathalyzers must be regularly calibrated and maintained according to strict standards to ensure accuracy. Your attorney can request the calibration and maintenance records for the specific breathalyzer used in your case. If the records are incomplete, inaccurate, or indicate that the device was not properly maintained, it could cast doubt on the reliability of the results.
• Proper Operation Procedures: Law enforcement officers must be properly trained and certified to operate breathalyzers. Your attorney can investigate whether the officer who administered the test followed the correct procedures, including the observation period, proper breath sample collection, and adherence to manufacturer guidelines. Any deviations from these procedures can be grounds for challenging the results.
• Radio Frequency Interference (RFI): Breathalyzers can be susceptible to interference from radio frequency signals, such as those emitted by police radios, cell phones, and other electronic devices. If RFI was present during the test, it could potentially skew the results.

2. Challenging the Physiological Factors Affecting BAC

Several physiological factors can influence the accuracy of breathalyzer readings. Your attorney can explore whether any of these factors might have contributed to an inaccurate BAC result in your case:

• Body Temperature: Breathalyzers assume a standard body temperature when calculating BAC. If your body temperature was significantly higher or lower than normal at the time of the test, it could affect the accuracy of the reading. Fever, hypothermia, and strenuous exercise can all alter body temperature.
• Breathing Patterns: As mentioned earlier, abnormal breathing patterns can affect the concentration of alcohol in the breath. Hyperventilation, holding your breath, or having a shallow breath can all influence the results.
• Medical Conditions: Certain medical conditions, such as diabetes, acid reflux, and lung diseases, can affect the accuracy of breathalyzer readings. For example, individuals with diabetes may have elevated levels of acetone in their breath, which can be mistaken for alcohol by some breathalyzers.
• Mouth Alcohol: The presence of alcohol in the mouth, due to recent consumption, mouthwash, or other sources, can artificially inflate the BAC reading. This is why officers are required to observe individuals for a specific period before administering the test to ensure that any mouth alcohol has dissipated. However, even with an observation period, residual mouth alcohol can still be a factor.
• Hematocrit Levels: Hematocrit refers to the percentage of red blood cells in your blood. Breathalyzers assume a standard hematocrit level when converting breath alcohol concentration to blood alcohol concentration. Individuals with significantly higher or lower hematocrit levels may have inaccurate BAC readings.
• Gender and Body Composition: Women typically have a higher percentage of body fat and lower water content than men. This can affect the distribution of alcohol in the body and lead to higher BAC readings for women compared to men with the same alcohol consumption.

3. Challenging the Legality of the Stop and Arrest

Even if the breathalyzer test was accurate, the results may be inadmissible in court if the initial traffic stop or arrest was unlawful. Your attorney can investigate whether the officer had a valid legal reason to stop your vehicle and whether there was probable cause to believe that you were driving under the influence. If the stop or arrest was illegal, any evidence obtained as a result, including the breathalyzer results, may be suppressed.

• Reasonable Suspicion: To initiate a traffic stop, an officer must have a reasonable suspicion that a traffic violation has occurred or that criminal activity is afoot. This suspicion must be based on specific and articulable facts, not just a hunch.
• Probable Cause: To arrest you for DUI, the officer must have probable cause to believe that you were driving under the influence. Probable cause is a higher standard than reasonable suspicion and requires more evidence, such as erratic driving, slurred speech, or a failed field sobriety test.
• Field Sobriety Tests: Field sobriety tests (FSTs) are standardized tests used by law enforcement to assess a driver’s impairment. These tests include the Horizontal Gaze Nystagmus (HGN) test, the Walk-and-Turn test, and the One-Leg Stand test. The results of FSTs are subjective and can be influenced by various factors, such as fatigue, medical conditions, and nervousness. Your attorney can challenge the validity of the FST results and argue that they did not provide sufficient probable cause for your arrest.

4. Expert Testimony

In many DUI cases, expert testimony is crucial for challenging breathalyzer results. Your attorney can retain experts in fields such as toxicology, pharmacology, and breathalyzer technology to provide testimony about the potential sources of error in the breathalyzer test, the physiological factors that can affect BAC, and the limitations of field sobriety tests.

Specific Considerations for Different Breathalyzer Models

It’s also important to understand the specific limitations and potential errors associated with the particular breathalyzer model used in your case. Here are some common breathalyzer models and their potential issues:

• Intoxilyzer 5000/8000: These are widely used infrared spectrophotometry breathalyzers. Potential issues include RFI susceptibility, improper calibration, and the assumption of a standard partition ratio (the ratio of alcohol in breath to alcohol in blood). Variations in an individual’s partition ratio can lead to inaccurate BAC readings.
• DataMaster DMT: Another commonly used infrared spectrophotometry breathalyzer. Similar to the Intoxilyzer, the DataMaster DMT can be affected by RFI, improper calibration, and variations in partition ratios.
• AlcoSensor IV/V: These are fuel cell breathalyzers often used for preliminary breath tests (PBTs) at the roadside. PBTs are less accurate than evidentiary breath tests conducted at the police station and are primarily used to establish probable cause for an arrest.

The Importance of Legal Counsel

As emphasized throughout this article, challenging a breathalyzer result is a complex legal and scientific undertaking. It’s essential to consult with a qualified DUI attorney who has experience in challenging breathalyzer evidence and who can thoroughly investigate the facts of your case. An attorney can:

• Evaluate the strengths and weaknesses of the prosecution’s case.
• Identify potential defenses and legal strategies.
• Negotiate with the prosecutor to potentially reduce or dismiss the charges.
• Represent you at trial and present evidence to challenge the breathalyzer results.

Beyond Breathalyzers: Blood Tests and Alternatives

While breathalyzers are the most common method for measuring BAC, blood tests are often considered more accurate. Blood tests are typically administered at a hospital or medical facility and analyzed in a laboratory. Blood tests eliminate some of the potential sources of error associated with breathalyzers, such as variations in breathing patterns and body temperature. However, blood tests also have their own potential issues, such as improper sample collection, storage, and analysis.

In some cases, a urine test may be used to detect the presence of alcohol in the body. However, urine tests are less accurate than breath or blood tests because they measure the concentration of alcohol metabolites, not the actual BAC. Urine tests are also susceptible to contamination and dilution.

If you are unable to take a breathalyzer test due to a medical condition or other reason, you may be required to submit to a blood test. It’s important to understand your rights and obligations regarding chemical testing and to consult with an attorney if you have any questions or concerns.

The 15-Minute Observation Period: Why It Matters

The 15-minute observation period is a crucial aspect of breathalyzer testing. During this time, the officer must continuously observe the individual to ensure that they do not eat, drink, smoke, vomit, or regurgitate anything. The purpose of the observation period is to prevent the presence of mouth alcohol from artificially inflating the BAC reading. If the officer fails to properly observe the individual for the full 15 minutes, the breathalyzer results may be challenged in court.

Some states have specific regulations regarding the observation period, including requirements for documentation and record-keeping. Your attorney can investigate whether the officer complied with these regulations in your case.

Understanding Implied Consent Laws

All states have implied consent laws, which mean that by operating a motor vehicle on public roads, you have impliedly consented to submit to chemical testing if requested by law enforcement. Refusing to submit to a breathalyzer or blood test can result in serious penalties, including license suspension, fines, and even jail time. However, the specific penalties for refusing a chemical test vary by state.

It’s important to understand the implied consent laws in your state and to consult with an attorney if you have any questions about your rights and obligations.

Future of Breathalyzer Technology

Breathalyzer technology is constantly evolving, with new devices and methods being developed to improve accuracy and reliability. Some emerging technologies include:

• Fuel Cell Sensors with Improved Accuracy: Advancements in fuel cell technology are leading to more accurate and reliable breathalyzer devices.
• Spectroscopic Techniques: New spectroscopic techniques are being developed to measure alcohol concentration in the breath with greater precision.
• Wearable Alcohol Sensors: Wearable sensors are being developed to continuously monitor BAC levels in real-time. These sensors could potentially be used to prevent drunk driving and to monitor individuals with alcohol-related conditions.
• Ignition Interlock Devices with Enhanced Features: Ignition interlock devices, which require drivers to pass a breathalyzer test before starting their vehicle, are becoming more sophisticated and incorporating features such as GPS tracking and camera monitoring.

As breathalyzer technology continues to advance, it’s important for legal professionals to stay informed about the latest developments and to understand the potential implications for DUI cases.
