DON’T USE A GIMMICK TO TRY TO BEAT THE DUI BREATHALYZER!

Any person who believes he or she can read a website or watch a YouTube video to learn how to beat a breathalyzer test, is an idiot. No one should think that a gimmick like putting pennies in your mouth will work and help the person beat a modern, forensic DUI breathalyzer.

Today’s breathalyzer calculator devices are 6^th or 7^th generation technology, using either infrared spectroscopy or advanced fuel cell systems, or both. Original breath alcohol testing equipment was invented in the 1930s and has gone through dozens of modifications, fail-safe procedures, computerization of results, and reports of malfunctions.

SEEKING TO DETERMINE THE PERSON’S BREATHALYZER LEGAL LIMIT USING IMPLIED CONSENT LAW

DUI-DWI laws around the United States have a type of “special” impaired driving law that was created in the early 1950s, called “implied consent” laws. Georgia DUI laws originally permitted a driver to have a 0.15 BAC level, but pressure from the federal government has pushed the adult BAC level to 0.08 grams percent in 2018.

These implied consent statutes apply ONLY to citizens charged with drunk driving and drugged driving cases. Up until that time, only one kind of driving while intoxicated crime existed, which was called various names in different states:

DUI less safe in Georgia (D.U.I.)

Operating while intoxicated (OWI) in Indiana

Driving while impaired (DWI) in North Carolina

Operating under the influence (OUI) in Maine

Driving while under the influence (DWUI) in Wyoming.

The purpose of an implied consent law ORIGINALLY was to use the threat of taking away a person’s right to drive to convince the driver to consent to a post-arrest sample of blood, breath or urine. When this forensic evidence is collected, it creates a SECOND type of DUI charge: being over the legal limit, which is known by DUI attorneys in most states as DUI “per se” (pronounced PER SAY).

Per Se Meaning: How Is a DUI “Per Se” Different?

Quickly translating this, the already-arrested driver could be convicted of driving under the influence EVEN without any proof of bad driving or the inability to drive safely, due to an intoxicating or impairing substance. This meant that the Prosecutor’s job became easier to secure a conviction, and required much greater DUI defense lawyer knowledge of breathalyzers, field sobriety tests, and alcohol or drugs testing protocols.

The advent of such laws also helped spawn a sub-specialty of criminal defense law, sometimes called “drunk driving defense.” For about 20 years, the National College for DUI Defense has overseen the American Bar Association’s testing and certification of criminal lawyers to become a Board-Certified DUI attorney, which is recognized in most states across America.

REFUSAL MAY NOT BE THE RIGHT ANSWER

While many DUI lawyers post “blanket” legal advice to “refuse” the breathalyzer test, this is not the best advice in many states. These 7 state law examples explain this point:

North Dakota – Prison time or jail time (felony vs misdemeanor) for refusal to blow;
Georgia – a breathalyzer refusal can trigger a ONE YEAR loss of all driving privileges – with no work permit!
Arizona – the national leader in forcible blood draws for those who refuse to blow into a breathalyzer. But now, the police must seek an electronic search warrant.
Nebraska – a refusal to provide a breath alcohol test can mean mandatory installation of an ignition interlock device to be able to drive. Georgia adopted this type of interlock alternative law effective July 1, 2017.
New Jersey is particularly harsh on repeat offenders, taking away the right to drive for 10 years, following by an 11 YEAR interlock requirement, for a 3^rd DUI offender.
Florida – 18-month total loss of all driving privileges. If this is a second “refusal,” he or she can serve up to a year of jail time plus a $1,000 fine.
Michigan – not only a one-year suspension applies, but 6 points are added to your driver’s license record. Plus, you must pay a $2,000 “driver responsibility fee.”

IF I DON’T REFUSE THE BREATHALYZER, WHAT SHOULD I DO?

Because he is only licensed to practice law in Georgia, Atlanta DUI lawyer William C. Head will only give advice in Georgia. His advice (for a typical DUI case not involving death or serious injury or a felony DUI, due to repeat DUI prior offenses) is as follow:

Don’t talk. Do not explain driving conduct. Do not admit drinking alcohol or drug usage (including prescription drugs). Give documents requested by police (driver’s license, proof of insurance, etc.) and then shut up. You are only required to give your name and address.
Do not take any field sobriety test of any type. This includes the portable breathalyzer, verbal exercises like the “ABC” recitation, or any eye test or agility exercises. All field sobriety tests are optional and voluntary, and declining to do these non-scientific exercises has NO BEARING on your right to drive.
If arrested, agree to take the requested implied consent test in Georgia, after the arresting officer has read you the Georgia implied consent advisement. It begins, “Georgia law REQUIRES you to submit….”
Once the officer obtains his or her breathalyzer test on the Intoxilyzer 9000 (or in rare cases, a blood test), you have the RIGHT to an independent test of your choice. Select a hospital or 24-hour clinic of YOUR CHOICE, within a reasonable driving distance, and get a blood test. It need not be in the county where you were arrested. You must pay for this blood collection and testing.

TOP 50 WAYS TO BEAT A BREATHALYZER

Manifestations and actions of Defendant being a drunk driver don’t match test readings (3^rd party witnesses available to testify for the accused). Sometimes called the “disconnect defense.”
Breath test officer untrained or marginally trained and cannot explain to a jury anything about how breath testing works. The officer does not have to be an electrical engineer, but he or she should be able to explain the primary functions and operations of the device that takes in a volume of breath and ultimately reports a “number” (or two numbers) that are used for trying to convict the accused citizen.
Officer fails to follow breath test training manual protocols, such as waiting period (deprivation period) before retesting after an aborted or out-of-parameters test.
Officer fails to adhere to the mandatory steps for assuring that the device is not being affected by possible actions of police near the device that may create false positives. Some ways this can happen is to have any device with an electromagnetic field too close to the testing device, like a cell phone that is the “on” position.
Defendant has a physical problem or health limitation, which the officer did not discover through medical screening or simply failed to ask questions about, so as to possibly switch to a type of test (blood test) that would not raise doubt about the reliability of contamination of the breath test device results.
Testing room circuitry of the power source of the breathalyzer device has a problem (microwave oven or copier sharing the same circuit, causing brownout). The manufacturers of all breath testing devices generally specify in the factory manual that the power source must be a dedicated, “clean” electrical source).
Vapors with hydrocarbons in the breathalyzer test room that can contaminate the sample chamber and cause false positive readings. Examples of possible sources of error: recently painted walls or trim; certain cleaning solutions like Formula 409, smoking in or near the breath instrument, varnishing floors or using polyurethane to seal a desktop or other surface. A drunk driving suspect who has had environmental exposure to volatiles may have a cumulative reading of ethanol (drinking alcohol) and the inhaled or absorbed chemicals. This is “reasonable doubt” for a jury to say, “not guilty.”
Defendant unable to blow enough sample volume due to age, diminished lung capacity or body size, respiratory health or the inability to achieve a leveled-off BAC breath alcohol level (most breathalyzer machines require: adequate TIME blowing, delivering enough PRESSURE to indicate deep lung air, and that the breath machine “see” a leveling off or the slope from the SLOPE detector readings).
Improper or inadequate inspections that do not comport with State regulations and protocols for periodic inspection by State inspectors. (example: no linearity proven, or the difference check was not within specifications)
Use of machine after factory repair but before a new calibration check is conducted by Georgia area supervisor at the police site. Because these are forensic machines that may be damaged during shipment, or which may not perform properly even after coming back from the factory from being serviced, most (if not all states) require a routine calibration and maintenance check before the device is put back into service.
After an auto crash, air bag defenses – “the Tyndall effect” – diffusion and refraction of light; propellant exposure; cut lips; lung and airway irritation & fluid build-up from caustic gas propellant. Only older air bags have talc or baking soda packing materials, so no particulate matter gets propelled into the driver’s lungs with newer air bags (after 2000 model).
Video or audio tape contradicts the high breath reading and supports an argument to a jury that no person twice (or three times) the legal limit can walk and talk like this. An excellent video (from police cars, the new body cams or even an adjacent premises video, showing no impairment at the high BAC level revealed by the breath test device.
Very high breath test result, yet the Defendant never urinates for 3 to 4 hours or more. Using medical expert, point out the physiological impossibility of not having to urinate.
Unintentionally ingesting alcohol, from Nyquil®, Vicks Formula 44®, lip balms, toothache drops, etc. This also can occur from consuming a party punch in which no disclosure of the sweet liquid being laced with alcohol is given.
Something in mouth containing alcohol or a similar hydrocarbon volatile chemical that reports as ethanol (Breath Drops with SD alcohol).
Residue of something in the suspect’s mouth that may contain interfering or contaminating substance (Skoal® snuff – wintergreen; Altoids® curiously strong mints, Wonder® bread, Sprite® soda)
Dentures, gingivitis, bridgework, “pockets” from gingivitis that can retain alcohol within those pockets and then be delivered into the sample chamber of the breath testing machine.
Vomiting, belching (even a silent belch or regurgitation that is not expelled from the mouth cavity) within 20 minutes of test (some states say 15 minutes) without first rinsing the mouth with water or re-starting the breath test with an inadequate deprivation period before retesting.
Insufficient observation period, as per breath test training manual (some states [ex: TN, MI] say any variation or timing error excludes test, others [ex: GA] say, goes to weight and credit)
Actual improper test sequence or out of “agreement” tests, without running follow-up tests to correct [ex: both results must be within 0.020 of each other, in most states]
The officer’s police report supports sobriety (by not enumerating the usual signs of an intoxicated person), or due to a lack of full investigation of alternative causes, like physically manhandling the DUI arrestee.
Where a rising BAC defense can be mounted from the police dispatch call times, and video footage showing time of driving, so as to argue that the blood alcohol content would have been lower than at the time of testing (if available in your state of arrest, such as Texas)
Elevated breath temperature caused by fever, hot tub, sauna, detention in hot sun or back of patrol car in summer, dancing, menstrual cycle, etc. [only Draeger® breath test devices are supposed to catch this and adjust for elevated breath temperature].
Failure to verify that the simulator temperature remained constant during testing and within tolerance; otherwise, results cannot be accurate.
Breath/blood ratio (2100:1) not proven to be Defendant’s ratio. This variance is proven through expert testimony that reveal how a minor error gets multiplied 2100 times; 0.12 = 17/10,000,000^th of an ounce of actual alcohol in the breathalyzer chamber on the Intoxilyzer 5000 devices. As an alternative approach, the DUI lawyer may show Defendant has abnormally LOW blood/breath conversion ratio through testing/experts
If BatMOBILE, wiring issues and electrical configuration exist; a false positive result can be rendered. These mobile BAC testing vans have AC/DC conversion issues; possible low voltage spikes.
No proper periodic testing of quantities of commonly occurring interfering substances likely found in a living subject, to assure machine’s ability to distinguish alcohol from other volatiles. The chemicals naturally produced by a diabetic’s breath during ketoacidosis are not introduced into the breath testing device, during calibration checks.
Improper or incomplete computer data or “function key” tests that do not get recorded during periodic inspections. In Florida, the inspectors were caught unplugging the Intoxilyzer 8000 when a calibration check was failing, so as to make the machines look “perfect.
The computer source code is ordered to be analyzed for proper operation, and the testing device is programmed incorrectly, to not allow a breath test when a person with small or diminished lung capacity gives a sample.
Gastric reflux, slow gastric clearing, or hiatal hernia preferably diagnosed and treated by a gastroenterologist before the DWI arrest occurred
Officer refuses to permit second, independent test sought by Defendant, or at the selected independent test location or physician of his or her choice
Mouthpiece not examined (plastic extrusion blocking tube = refusal)
Simulator solutions not retained for subsequent re-analysis, if challenges to the precision of the standard is made.
Simulator solutions not checked by GC-Mass Spec analysis upon receipt from company that sells them (i.e., RepCo Marketing of NC!!!)
Inherent “sampling variability” or “margin of error” issues (e.g., 0.088 reading in an 0.08 state, and manual acknowledges +/- 0.01 precision problem)
Blowing pattern irregularities (blubbering and crying causing artificially high reading that was triggered by a water vapor problem) and an elevated reading on the breath test instrument.
Denial of blood test—the more reliable target with the more accurate method of analysis – especially if the state (e.g., California) implied consent law allows the DUI detainee to opt for a blood alcohol content test, versus a breathalyzer.
Defendant has been on strict high protein DIET and then introduces carbohydrates, thereby triggering auto-generated isopropyl alcohol production when ketones are converted to isopropyl alcohol
Discovery not provided in a timely or complete manner by the prosecutor prior to trial; results excluded, whether a breath alcohol test or blood alcohol test or DUI drugs.
Failure to give timely, completely or “correctly” give the proper version (e.g., for a CDL driver or an underage driver) of the full state implied consent warning
Defendant has been diagnosed with diabetes, is “borderline” diabetic or is hypoglycemic and consumes alcohol in any amount, causing conversion of high acetone levels into isopropyl alcohol
Officer gives implied consent, but then makes improper, coercive statements to the arrested subject, thereby obtaining the breath test result while violating the law, which generally states that such tactics cannot provide a voluntary consent to breath testing.
Officer obtains first BAC results, which will not support a per se case, then waits a few more minutes and retests the same person, obtaining a reading ABOVE the per se Most state laws require that ALL test cards and computer database results be retained for evidentiary purposes, and that such manipulation is illegal.
Officer gives implied consent, but then goes too far by threatening dire license suspension issues for which there is no factual basis (misstating consequences of what will occur to driving privileges, if not true and consistent with implied consent laws.)
State fails to prove that results were obtained with the statutorily imposed time limit (typically, 2 or 3 hours after driving ended, but other states say 4 hours, or do not give a time limit.)
State fails to prove the alcohol was consumed either DURING driving or BEFORE driving ended (this is the drunk driving law in most states)
Officer fails to get his/her annual or periodic “updates” in training, thereby disqualifying the test operator from administering tests.
The person who collects the breathalyzer tests from the arrested individual types in the operator number of a different breath machine technician because the officer running the tests had either allowed his or her permit to lapse, or never had his or her permit, but can read the “number” of an approved breath test operator off the certificates in the breath testing room.
In handling case, officer commits crime (e.g., obstruction of justice, perjury) to conceal evidence; prosecutor cannot proceed to trial OR (more commonly) the pullover officer makes an illegal, warrantless stop or arrests the person for drunken driving without probable cause. All evidence collected after an illegal, unconstitutional arrest is thrown out by the trial judge, if he or she rules that the DWI-DUI arrest was illegal.
“FIRD” Defense – The breath test officer has been: Fired, Indicted, Retired (and moves away) or Died, and cannot (or WILL not) be in court to lay a proper foundation for the breathalyzer test.
