Freudenrich, Ph.D. Table of Contents Introduction to How Breathalyzers Work Why Test? Principle of Testing Types of Devices: Breathalyzer Types of Devices: Intoxilyzer Types of Devices: Alcosensor III or IV Lots More Information Compare Prices for Breathalyzers Types of Devices: Alcosensor III or IV Modern fuel-cell technology (which may power our cars and even our houses some day) has been applied to breath-alcohol detectors. Devices like the Alcosensor III and IV use fuel cells. The fuel cell has two platinum electrodes with a porous acid-electrolyte material sandwiched between them. As the exhaled air from the suspect flows past one side of the fuel cell, the platinum oxidizes any alcohol in the air to produce acetic acid, protons and electrons. Oxidation of Alcohol If you strip off hydrogens from the right carbon of ethanol in the presence of oxygen, you get acetic acid , the main component in vinegar . The molecular structure of acetic acid looks like this: O || H 3 C - C - O - H where C is carbon, H is hydrogen, O is oxygen, the hyphen is a single chemical bond between the atoms and the || symbol is a double bond between the atoms. For clarity, the bonds of the three hydrogen atoms to the left carbon atom are not shown. When ethanol is oxidized to acetic acid, two protons and two electrons are also produced. The electrons flow through a wire from the platinum electrode. The wire is connected to an electrical-current meter and to the platinum electrode on the other side. The protons move through the lower portion of the fuel cell and combine with oxygen and the electrons on the other side to form water. The more alcohol that becomes oxidized, the greater the electrical current . A microprocessor measures the electrical current and calculates the BAC. Operators of any breath alcohol testing device must be trained in the use and calibration of the device, especially if the results are to be used as evidence in DWI trials . Law enforcement officers can carry portable breath testing devices that use the same principle as full-size devices. Court cases can turn on the perceived accuracy of a breath test, however, so prosecutors rely on the results obtained from full-size devices.

Free consultation. 865-546-4292 Testing for Blood Alcohol Content By driving a vehicle in the state you give your "implied consent" to submit to a chemical test for alcohol or drug content if suspected by a police officer of driving under the influence. In this state, the officer will only offer a breath test. If you refuse, you will lose your license. When state law talks about "Alcohol Content" or BAC, it refers to the number of grams of alcohol present per 100 milliliters of blood in the person's system. A BAC of 0.10 would mean that the person has 1/10 of a gram of alcohol per every 100 milliliters of blood. So when it comes to the legal limit of 0.08, we are talking about a small amount of measurable alcohol. Blood Tests Typically, when chemical evidence is admitted for use by the prosecution, there are more ways to attack the accuracy of a breath test than a blood test. Blood testing involves taking a sample of blood and directly measuring the alcohol content. A blood test also measures for the presence of prohibited drugs and their metabolites in your system. If you have been arrested for OUI in the state or already consented to a , breath test, you are permitted to have a second blood test conducted by an independent source, at your expense. While blood tests are the most reliable method of testing for BAC, they are by no means infallible. Typically, blood samples are drawn by hospital staff. (In some jurisdictions, a police officer might have sufficient training as a phlebotomist to draw your blood, but this is less often the case). In any event, the methods taken to draw blood can have a significant impact on test results and the admissibility of this evidence. Medical personnel must have appropriate credentials and follow precise procedures, otherwise, the test results may be subject to challenge. Contaminated samples or flawed procedures can influence and erroneously inflate BAC results. Provided below is a partial list of sources and examples of defense(s) related to blood tests: HIPAA: The Health Insurance Portability and Accountability Act of 1996 is an evolving piece of legislation and area of healthcare law. Basically, any entity that has access to your medical records or produces any patient medical information (such as test results), must adhere to a strict set of complex guidelines in order to protect patient privacy. Noncompliance with HIPAA regulations by a healthcare provider can influence the admissibility of your blood test results and likewise the outcome of your case. Yeast: If introduced into the blood sample, can produce falsely high BAC readings. Yeast consumes blood sugars. The byproduct is alcohol - indistinguishable from alcohol whose source is an alcoholic beverage. Non-sterile tube: The top of the blood test tube has been contaminated or has not been properly sterilized. Administrative Errors: The lab or hospital has incorrectly identified your sample and your test results are from someone else’s blood. This can be definitively verified through a DNA test. Alcohol Swab: If the site of the needle puncture on your arm was first sterilized with any substance containing alcohol, this alcohol can be transferred to the needle and ultimately into the blood sample and generate erroneously high BAC results. Defective Vacuum: Tubes used to collect blood contain a vacuum that helps deposit blood into the tube. If this vacuum is damaged or does not function properly, contaminants can be introduced that could influence test results. Breath Tests A breath test measures only alcohol and is more error prone. Equations are used to gauge the relative amount of alcohol contained in a sample of deep lung (alveolar) air and law enforcement then has to calculate the amount of blood alcohol that should be present. Testing alveolar air has its problems, in that the sample does not necessarily remain constant. Temperature and breath patterns also affect the content of any given breath sample. Also, many common substances can register as alcohol when in fact they are not. There are several different breath test machines (commonly referred to as a breathalyzers) available on the market. They are manufactured by private companies and sold to law enforcement agencies. These different devices come with their own unique characteristics and requirements for proper use and care. The improper use, testing and/or maintenance of these various devices can play a significant role in your defense. Likewise, it is important to select an attorney with a high degree of familiarity with these machines. Even the most advanced breathalyzers, such as the Intoxilyzer, has its problems.The Intoxilyzer uses infrared spectrometry to measure the degree of alcohol in a breath sample. A quartz lamp inside the machine radiates infrared energy through the sample. The amount of energy that makes it through the sample (and is not absorbed by alcohol) is then measured and calculations are made. The greater the amount of alcohol present in the sample being analyzed, the greater the absorption. However, to deliver results admissible in court, the breath testing device must have been properly maintained and operated. Even when functioning properly, it has a modest but inherent margin of error. So, even if you've failed a chemical test, there are ways to challenge the results. A skilled attorney must be engaged to adequately assess how these test results may be successfully defended or thrown out altogether. Field Sobriety Tests Most OUI cases include evidence from field sobriety tests ("FST’s"). These tests, such as the One Leg Stand, Walk and Turn and Horizontal Gaze Nystagmus (Eye Test) are used by law enforcement to establish probable cause and help secure DUI convictions. These roadside tests are completely voluntary. Refusing the submit to field testing will not result in the suspension of your driving privileges (unless you are on probation and/or have another case pending in which a Judge has ordered you are not to refuse to take these tests). The biggest drawback is that, typically, the prosecutor can use your refusal against you in court. It is important to understand that no studies conclusively link the roadside "Field Sobriety Tests", to a persons level of intoxication. Even when conducted under ideal circumstances, the best studies show less than an 80% rate of accuracy. Also, these tests results are influenced by how well the officer conducted the tests and in some instances, his or her own interpretation of your performance. These circumstances can lead to results that are unreliable or inconclusive – results that can be successfully defended more often than most defendants realize. Only three of the tests available to officers have sufficient merit to be recognized by the National Highway Traffic Safety Administration (NHTSA). These tests include Horizontal Gaze Nystagmus Test, the Walk and Turn Test and the One Leg Stand Test. No other tests given in the state have been validated in any official way. Examples include the Finger to Nose Test, the Rhomberg Balance Test, counting or saying the ABCs backwards, counting ones fingers, etc. There is no proven correlation to these test results and ones ability to safely operate a motor vehicle. The Arrest Process This section provides an overview of the process an officer will go through to determine whether to arrest you for driving under the influence of alcohol or drugs. Signs of Impairment People operating a vehicle under the influence typically exhibit some symptoms of impairment. The vehicle might be going extremely fast or extremely slow. Officers look for a willingness to take risks, poor coordination, slowed reactions and impaired vision. Routine traffic violations are also used - violation of a posted control sign, a failure to use a turn signal, inappropriate use of high beams or other cues that alert the officer to a driver that might be influenced by intoxicants. An officer requires a reasonable belief that the driver was operating in an unreasonable manner, or a reasonable suspicion that a law has been broken, to justifying pulling a vehicle over. The National Highway Transportation Safety Administration (NHTSA) has established specific visual cues that indicate a driver’s probability of being legally intoxicated. Officers often rely upon this information to establish a basis for stopping suspected drunk or drugged drivers. When the officer sees more than one cue, the probability rises. The probabilities listed below correspond to the officer observing only one cue: THE OFFICER'S VISUAL CUE CORRESPONDING PROBABILITY OF IMPAIRMENT Headlights off 30% Accelerating or decelerating rapidly 30% Turning abruptly or illegally 35% Stopping inappropriately (other than in the lane of travel) 35% A slow response to traffic signals 40% Driving into or crossing traffic 45% Erratic application of the brakes 45% Driving with tires on center or lane marker 45% Drifting 50% Following too closely 50% Stopping without cause in the lane of traffic 50% Driving slower than 10 miles per hour 50% Swerving 55% Driving on other than the designated highway 55% Weaving 60% Almost striking object or vehicle 60% Appearing to be drunk: (eye fixation; tightly gripping the steering wheel; gesturing erratically or obscenely; face close to the windshield; drinking in the vehicle; driver's head protruding from vehicle) 60% Straddling center or lane marker 65% Turning with wide radius 65% There is also an opportunity for the observation of several more cues of impairment when an officer initiates a traffic stop. These observations can be used to prove the driver was under the influence. Typical observations include a lack of response or a slowed response to flashing lights or sirens, pulling over suddenly or in an inappropriate place, abruptly swerving or attempting to flee, as examples. Prosecutors and officers also use this opportunity to look for signs of "divided attention", invoking a theory frequently used to explain impairment. It is based on the assumption that the ability to execute multiple tasks simultaneously is limited by alcohol or drugs in the system. Flashing lights, sirens and other distractions must be dealt with that a driver under the influence may have trouble handling. However, there could be other reasons why a driver experienced some difficulty in these situations. Making Contact with the Driver Once the stop has been completed, the officer begins the process of making personal contact with the driver. After an officer approaches the vehicle, they observe and interview the driver, usually while the driver remains in the vehicle. The officer typically asks the driver general questions while looking for evidence of impairment, such as an odor of alcohol, bloodshot eyes, flushed face, slurred or impeded speech, etc. The officer will also note if the driver has any trouble retrieving their license and registration from a pocket or glove compartment. The officer will also look around the vehicle for any evidence in plain view, such as beverage containers or drug paraphernalia. The officer may also administer some simple verbal exercises or other preliminary, seated sobriety tests to help determine impairment. Next, the officer decides whether to request that the driver get out of the vehicle. Does the driver trip, stumble or use the door for support? The officer observes how a driver exits the vehicle. Screening Once the driver is out of the vehicle, the officer enters a pre-arrest screening phase of the DUI investigation. First, the officer administers field sobriety tests. These tests attempt to provide a judge (or jury) with clinical symptoms of impairment. They may also serve to reinforce the officers prior observations of the suspect. A skilled defense attorney will thoroughly scrutinize every detail of these tests. For example, the test results might be discredited by successfully asserting that: The officer didn't first properly demonstrate the test; The driver didn't under stand the test well enough to perform it; The lighting was insufficient; The road was uneven or otherwise unsuitable; The weather conditions were poor; That driver had a pre-existing physical condition which affected test performance... Even if an officer does everything possible to minimize these defense arguments, it can be difficult to conduct tests under flawless conditions. The "standardized" field sobriety tests that NHTSA recommends are Walk and Turn , One Leg Stand and Horizontal Gaze Nystagmus . Other, non-NHTSA standardized field sobriety tests include, among others, the Coin Toss Test , Finger To Nose Test and various Balancing Tests . Following the field sobriety tests, the officer's next task in a DUI investigation is typically to administer a preliminary breath test (PBT), which the police use to confirm the chemical basis for impairment. This test is performed with a hand-held device (often an Alcosensor III). This portable device generally does not have an attached printer. A preliminary breath test is for investigatory purposes only and results are not typically admissible in Court. If the officer has evidence of drug impairment, it will be necessary to seek out assistance from an officer who has been trained and certified as a Drug Recognition Expert (DRE). Note that the majority of law enforcement officers do not have DRE status. Likewise, most officers are not certified to administer a standardized drug recognition examination of a suspect. The arrest occurs at the conclusion of the pre-arrest screening process. If the officer decides to arrest the suspect, he must have probable cause that the driver is under the influence of alcohol or drugs. If mistakes or improper procedures by law enforcement occurred at any point along this process, a good OUI defense lawyer will make certain that these facts are appropriately used in your defense. Sobriety Checkpoints Sobriety checkpoints (police roadblocks) used to screen drivers for OUI are legal in the state. At a given location, these checkpoints provide a place where law enforcement can stop vehicles, question drivers and observe them for signs of intoxication. These checkpoints can result in a considerable number of DUI arrests each year. Driving makes you are subject to these DUI checkpoints. If you turn around prior to reaching the checkpoint, there is a good chance that you will be followed. If the officer notices a traffic violation or other driving behavior that provides just cause to pull you over, you will likely be stopped. If you fail to stop for a checkpoint, the police can pursue and pull you over. If you are at a OUI Checkpoint and the officer develops a reasonable suspicion that you are under the influence, you may be detained further. This detention might include requests for you to perform field sobriety tests, or to answer questions about your intake of alcohol or drugs. If the officer develops probable cause, you may be arrested and asked to perform a test of your breath, blood or urine to determine the presence of alcohol or drugs. There are a number of guidelines law enforcement must follow to properly conduct sobriety checkpoints. These exact procedures must conform to state regulations and also to avoid violating your constitutional protections from unreasonable search and seizure. For example, detentions must be brief and only long enough ensure you are not intoxicated, unless some other crime is observed or in progress. To adequately ensure that your rights have not been violated and all of your defenses have been thoroughly explored, consult an experienced drunk driving practitioner if you have been arrested at a sobriety checkpoint.
