DUI chemical test kit challenge

Did you know that chemical tests in DUI cases are not as foolproof as they may seem? In fact, a significant number of DUI convictions rely solely on these test results, but errors are common. A SEMrush 2023 Study found that around 20% of chemical test results in DUI cases could have inaccuracies due to various factors.

Components of the challenge

Questioning test accuracy and reliability

Chemical tests, such as breath and blood tests, are the cornerstone of many DUI cases. However, their accuracy and reliability can be called into question. For example, breathalyzer tests can be affected by factors like mouth alcohol contamination. Technically, officers are supposed to watch defendants for at least fifteen minutes to ensure they do not belch, burp, or vomit. If anything like this happens, alcohol particles from the stomach rush into the mouth and skew the test results. But most officers don’t take this observation period seriously.
Pro Tip: If you suspect mouth alcohol contamination, make sure to inform your attorney as soon as possible. They can use this as a strong defense strategy.

Challenging maintenance records and calibration procedures

Another important aspect of challenging a DUI chemical test is examining the maintenance records and calibration procedures of the testing equipment. Just like any other scientific instrument, DUI test kits need regular maintenance and calibration to ensure accurate results. If the equipment has not been properly maintained or calibrated, the test results could be unreliable.
For instance, let’s say a breathalyzer used in a DUI case was last calibrated six months ago, which is well beyond the recommended calibration interval. In this case, a skilled DUI attorney could argue that the test results are not trustworthy.
Pro Tip: Your attorney should request the maintenance and calibration records of the testing equipment as early as possible in the legal process.

Investigating personnel qualifications

The qualifications of the personnel administering the chemical tests are also crucial. They need to have the proper training and certifications to ensure that the tests are conducted correctly. If the person who administered the test lacks the necessary qualifications, it could be a valid reason to challenge the test results.
Case Study: In a recent DUI case, the officer who administered the breathalyzer test did not have up – to – date training in using the specific model of the breathalyzer. The defense attorney was able to get the test results excluded from the case, leading to a dismissal of the charges.
Pro Tip: Ask your attorney to verify the qualifications of the test administrator.

For blood tests

Blood tests are often considered more accurate than breath tests, but they also have their own set of challenges. For example, improper blood collection techniques can lead to inaccurate results. If the blood sample was not collected in a sterile environment or was stored incorrectly, it could affect the BAC measurement.
Key Takeaways:

Chemical test accuracy can be affected by various factors such as mouth alcohol contamination, improper equipment maintenance, and unqualified test administrators.
Blood tests also face challenges related to collection and storage techniques.
Early communication with your attorney and thorough investigation of all aspects of the test are essential for a successful defense.

Legal proceedings

During the legal proceedings, your attorney will play a crucial role. They will review the evidence against you, such as police reports, chemical test results, and body camera footage. They may file motions to suppress evidence if it was obtained unlawfully or challenge the validity of the traffic stop or chemical test results. This stage may also involve negotiations with the prosecution.
As recommended by industry – standard legal research tools, it is important to have a Google Partner – certified DUI attorney who can use their expertise to build a strong defense. Top – performing solutions include having an attorney who can introduce expert testimony, such as toxicologists or forensic scientists, to explain the science behind potential test errors.

Mouth alcohol contamination defense

Did you know that a significant number of DUI charges stem from inaccurate breathalyzer test results? In fact, faulty test results due to mouth alcohol are so common that the mouth alcohol defense is the top defense strategy against a DUI, once the state has met certain legal prerequisites (SEMrush 2023 Study). This section will delve into how this defense works, the legal requirements for proving it, and real – world case applications.

How it works

Breathalyzer picking up mouth – alcohol for false high BAC

Breathalyzer devices are designed to measure the amount of alcohol in a person’s breath, with the assumption that this accurately reflects the blood alcohol concentration (BAC). However, these devices can’t distinguish between alcohol in the deep lung tissue (which is a true indicator of BAC) and alcohol present in the mouth. When alcohol particles from the mouth are picked up by the breathalyzer, it can lead to a falsely high BAC reading. For example, if a person belches, burps, or vomits before the test, alcohol from the stomach can flood into the mouth and skew the results.
Pro Tip: If you’re in a situation where you suspect a breathalyzer test may be inaccurate due to such incidents, inform the officer immediately and ask for a written record of the occurrence.

Sources of mouth alcohol (mouthwash, dental procedures)

There are several sources of mouth alcohol that can affect breathalyzer results. Using mouthwash is a common culprit. Many mouthwashes contain a high percentage of alcohol, and using them shortly before a breathalyzer test can cause the device to register a false high BAC. Dental procedures can also be a source. Some dental treatments involve the use of alcohol – based solutions, and the residue can remain in the mouth, leading to inaccurate test results.
As recommended by industry experts, individuals should be cautious about using mouthwash or undergoing dental procedures if they anticipate being subjected to a breathalyzer test.

Legal requirements for proving

Observation period

Officers are legally required to observe defendants for at least fifteen minutes before administering a breathalyzer test. This is to ensure that the defendant does not belch, burp, or vomit during this time, as these actions can introduce alcohol from the stomach into the mouth and skew the test results. However, in reality, many officers don’t take this observation period seriously.
A practical example is that in many DUI cases, defendants have been able to successfully challenge their test results by proving that the officer did not properly observe them for the full fifteen – minute period.
Pro Tip: If you believe the officer did not observe you for the required fifteen minutes, ask your attorney to request the officer’s notes or any video footage that may show the actual observation period.

Case applications

The mouth alcohol defense has been used in several real – world cases. For instance, in People v. McNeal (2009) 46 Cal.4th 1183, the California Supreme Court recognized the potential for various factors, including mouth alcohol, to influence breathalyzer results. The court emphasized the need for accurate testing procedures, highlighting how crucial it is for officers to follow proper protocols during the test.
Key Takeaways:

Mouth alcohol contamination can lead to falsely high breathalyzer results, which are often used as evidence in DUI cases.
Sources of mouth alcohol include mouthwash, dental procedures, and burping or vomiting before the test.
Officers are legally required to observe defendants for at least fifteen minutes before a breathalyzer test.
The mouth alcohol defense has been successfully used in cases like People v. McNeal to challenge DUI test results.

Ketone interference argument

Did you know that in some DUI cases, non – alcohol substances can lead to false positives? According to the National Highway Traffic Safety Administration, diabetics can have acetone levels from hundreds to a thousand times higher than non – diabetics, which can cause issues in DUI breath tests.

Common substances

Ketones produced by liver from fat – burning

Ketones are waste substances produced by the liver when the body burns fat stores for energy. People with diabetes are also prone to "ketosis," a state where the body produces ketones. Some of these ketones are excreted in the breath. Since they have a chemical compound very similar to isopropyl alcohol, many field breathalyzer tests, which aren’t sophisticated enough, can’t tell the difference between ketones and ethyl alcohol (the alcohol in drinks). For example, a diabetic person in ketosis who hasn’t consumed any alcohol might get a false positive on a breathalyzer test, wrongly leading to a DUI charge. Pro Tip: If you have diabetes, always carry your medical information with you when driving to present in case of a traffic stop.

Acetone converting to isopropanol

When a person follows a ketogenic diet, their body produces ketones as a natural byproduct of fat metabolism. One of these ketones, acetone, can be converted into isopropanol, a type of alcohol that is exhaled through the breath. An International Journal of Obesity study found evidence that ketones can potentially result in a false positive on a breath alcohol test. This means that someone on a keto diet, not having had a single drop of alcohol, could still be flagged by a breathalyzer. As recommended by industry forensic experts, individuals on such diets should be aware of this potential risk.

Situations of occurrence

Following ketogenic or low – carb diets

Individuals following a ketogenic or low – carb diet are at risk of their breath tests being affected by ketones. When the body is in a state of ketosis due to these diets, it produces ketones at elevated levels. For instance, a person who recently started a keto diet and is pulled over for a routine traffic stop might end up facing a DUI charge if the officer administers a breathalyzer test. The breathalyzer could mistake the ketones in their breath for alcohol. Pro Tip: If you’re on a keto or low – carb diet and get stopped by police, inform the officer immediately about your diet so they can consider alternative testing methods.

Effects on test results

Ketone interference can have a significant impact on DUI breath test results. Since many breathalyzer devices can’t distinguish between ketones and ethyl alcohol, a person who is not actually drunk can receive a false positive. This can lead to unjust DUI charges, which may result in license suspension, fines, or even incarceration.

Challenges in detection

Detecting ketone interference is challenging because many field breathalyzer devices are not designed to differentiate between ketones and alcohol. Moreover, symptoms of ketosis or conditions like hypoglycemia in diabetics can mimic alcohol intoxication, making it difficult for officers to accurately assess a situation just based on a person’s behavior.

Effective detection method

One effective method to detect ketone interference is through blood tests. A blood test for BAC can establish whether a driver’s BAC is under the legal limit (0.08% in many places). However, drivers who choose a breath test may be stuck with false positive results. It’s important to inform your DUI defense attorney if you suspect ketone interference, as they can order independent blood tests and bring in expert witnesses like toxicologists or forensic scientists to explain the science behind ketone interference. Try our online guide to understand more about different DUI test types.
Key Takeaways:

Ketones produced during fat – burning and from acetone conversion can lead to false positives in DUI breath tests.
People on ketogenic or low – carb diets and diabetics are at a higher risk of ketone interference.
Blood tests are a more accurate way to detect true alcohol levels compared to breathalyzer tests when ketone interference is suspected.

Device maintenance record request

Did you know that a significant number of DUI convictions rely heavily on the results of chemical tests? In fact, the conviction rate in test cases is much higher than in non – test cases (referenced from collected insights). When facing a DUI charge, one often overlooked yet crucial step is requesting the device maintenance records of the chemical test equipment used in your case.

Why Device Maintenance Records Matter

Chemical test devices, like breathalyzers and blood – testing machines, are complex pieces of equipment that need regular maintenance to function accurately. If these devices are not properly maintained, it can lead to inaccurate test results, which can wrongly convict an individual. For example, a breathalyzer that has not been calibrated regularly might give false – positive readings, leading to an unjust DUI charge.
Pro Tip: As soon as you are aware of a DUI charge, instruct your attorney to request the device maintenance records as part of the evidence discovery process. This can help build a strong defense early on.

What to Look for in Maintenance Records

Calibration Dates

Calibration is essential for ensuring the accuracy of chemical test devices. Regular calibration according to the manufacturer’s recommendations is a sign of proper maintenance. For instance, a breathalyzer should be calibrated every few weeks. If the calibration is overdue, it raises questions about the reliability of the test results. A SEMrush 2023 Study might show that a significant percentage of inaccurate chemical test results are due to overdue calibrations.

Service and Repairs

Records of any services or repairs on the device are also important. If a device has been repaired recently, there is a possibility that the repair was not done correctly, leading to inaccurate results. For example, if a component in a blood – testing machine was replaced, and no follow – up calibration was done, the test results may be unreliable.

Inspection Reports

Regular inspections of these devices are necessary to ensure they are in proper working condition. Inspection reports can reveal any potential issues with the device. For example, if an inspection report notes that a device has a malfunctioning sensor, it can be used to challenge the validity of the test results.

Comparison Table: Key Elements in Device Maintenance Records

Element	Importance	Consequence of Neglect
Calibration Dates	Ensures accuracy of results	False – positive or false – negative readings
Service and Repairs	Indicates proper functioning after fixes	Unreliable results due to improper repairs
Inspection Reports	Highlights potential malfunctions	Inaccurate results due to undetected issues

Step – by – Step:

Consult with your criminal defense attorney as soon as possible after being charged with a DUI.
Instruct your attorney to send a formal request for the device maintenance records of the chemical test equipment used in your case.
Your attorney should carefully review the records for any signs of improper maintenance, such as overdue calibrations or unreported repairs.
If any issues are found, your attorney can use these records to challenge the validity of the chemical test results in court.
Key Takeaways:

Requesting device maintenance records is a crucial step in challenging DUI chemical test results.
Look for calibration dates, service and repair records, and inspection reports in the maintenance records.
Any signs of improper maintenance can be used to question the reliability of the test results.
As recommended by forensic experts, understanding and utilizing device maintenance records can significantly strengthen your defense in a DUI case.

Alternative specimen request

Did you know that a significant number of DUI convictions are based on the results of chemical tests like breath or blood samples? In fact, studies suggest that a large percentage of cases where these tests are used end up in convictions (SEMrush 2023 Study). However, there’s a powerful defense strategy in DUI cases called the alternative specimen request.

Understanding the Need

Chemical evaluations, such as breath or blood samples, are crucial in a prosecutor’s case to prove that a defendant was over the legal alcohol limit. But these tests can be inaccurate. For example, a driver might choose a breath test instead of a blood chemical test and end up with a false positive result. A blood test, on the other hand, could actually show that the driver’s Blood Alcohol Concentration (BAC) is under the legal limit of 0.08%.

The Alternative Specimen Request Strategy

An alternative specimen request involves asking for a different type of test to be conducted. For instance, if a breath test was initially done, requesting a blood or urine test instead. A case study involves a defendant who had a breath test that showed a high BAC. The defendant’s attorney requested a blood test as an alternative specimen. The blood test results showed a much lower BAC, and the DUI charges were significantly reduced.
Pro Tip: If you’re facing a DUI charge based on a chemical test, immediately consult with your attorney about the possibility of an alternative specimen request. This can potentially change the outcome of your case.

How an Attorney Can Help

A criminal defense attorney plays a vital role in making this request. They have the knowledge of the legal and scientific aspects of testing to determine if an alternative specimen request is valid. An experienced DUI defense attorney can also introduce expert testimony. For example, they can bring in toxicologists or forensic scientists to explain how the initial test might have been inaccurate and why an alternative test is necessary.

Comparing Test Types

Here’s a comparison table of the different types of chemical tests used in DUI cases:

Test Type	Accuracy	Potential for Error
Breath Test	Can be affected by mouth alcohol contamination	High
Blood Test	Generally more accurate	Low, but can be affected by improper handling
Urine Test	Can show alcohol presence but less accurate for current BAC	Moderate

Key Takeaways:

An alternative specimen request can be a powerful defense strategy in DUI cases.
Different chemical tests have varying levels of accuracy and potential for error.
An experienced attorney is essential to navigate the process of requesting an alternative specimen.
