Novi Challenging DUI Tests

Police officers have various ways to establish probable cause for and gather evidence in support of DUI arrests. These methods often include the administration of field sobriety tests, as well as breathalyzer and blood tests to measure blood alcohol content (BAC). However, challenging DUI tests in Novi is a common defense practice due to the sometimes-questionable reliability of test results.

No tests are infallible because their administrators may make human errors and fail to follow procedures correctly. When irregularities occur, the test results may be inaccurate and inadmissible in court as evidence against you. A skilled operating while intoxicated (OWI) defense lawyer may be able to utilize compromised test results to build a strong defense to your charges.

Challenging Field Sobriety Tests in Novi

The National Highway Traffic Safety Administration (NHTSA) has a standardized battery of three field sobriety tests for law enforcement officers to administer during traffic stops. The standard battery includes the walk and turn, one-leg stand, and horizontal gaze nystagmus tests. Police officers use these tests to measure impairment in drivers if they suspect OWI.

According to the NHTSA, police officers must follow the exact procedures for properly administering these tests in the correct order. Inadequate training on the administration procedures can easily lead to false test results leading to unlawful arrests. Moreover, the results of these tests are entirely subjective, which can lead to misinterpretation of the results.

Inaccuracies in Breath Test Results

Police officers administer breathalyzer tests to measure a driver’s BAC at the time of the stop. By statute, drivers are operating while intoxicated when they drive with a BAC of .08 percent or higher. However, police officers must receive proper training to operate breath test machines appropriately. These breath alcohol testing machines require routine maintenance and calibration. Failure to adequately take care of the machines could lead to inaccurate results.

Drivers may also have certain medical conditions that could impact the reliability of breath test results. Officers must observe a 15-minute waiting period before administering the test, or the results may be invalid. Additionally, gastroesophageal reflux disease, heartburn, and the use of alcohol-based products like mouthwash could create artificially high BAC readings. With such confounding variables, it may be possible for an attorney to begin challenging a BAC test in a Novi OWI case.

Disputing Blood Test Results in Novi DUI Cases

Police officers often request search warrants from courts to administer a blood test to a driver the suspect was driving under the influence. These tests are usually administered when drivers refuse breath tests at the station. An experienced Novi defense attorney could challenge BAC blood test results in some situations.

If police officers administer a blood test on a driver without a search warrant from a judge or the driver’s informed consent, they may have obtained the blood sample illegally. This practice could make the blood test results being inadmissible in court.

Also, like breath testing, blood testing is prone to human and instrument error. A well-trained DUI defense lawyer can uncover these errors and bring them before the court seeking suppression.

After challenging the OWI blood test results in a Novi DUI case, the prosecution may be unable to meet the burden of proof they need to secure a conviction. Blood test results may also be compromised by other errors and irregularities in testing procedures that could lead to contamination, making the evidence inadmissible.

Novi DUI Test Challenges may Be Crucial at Trial

While field sobriety, breath, and blood test results can be instrumental in DUI prosecutions, they are subject to attack in some circumstances. A lack of adequate training, instrument error, a failure to follow standard procedures, and human error all may contribute to the unreliability of DUI test results. Not only could the test results be inaccurate, the tests may be completely inadmissible in court.

While these issues are not present in every case, they are one method that criminal defense attorneys may be able to use to fight back against DUI charges.

Client Reviews
Patrick Barone is the ONLY choice for DUI defense. He was realistic from the start and made it a point to look at my case before taking my money. As a business owner, when I think of attorneys, I think of the "shark infested waters. Patrick is a shark alright, but his prey is not the client; it's justice for his client. Ten stars Patrick!! Chris F.
Attorney Patrick Barone was very helpful and helped me understand the charge and sentence absolutely clearly. He also guided me through step by step helping me form a statement. His instructions were clear and detailed. It was obvious he cared about me understanding every important detail within my case. I would absolutely recommend this defense firm to anyone in need. Aaron B.
The Barone Defense Firm is the firm I recommend. They are truly concerned about the person, not just the legal issue, but the person as well. They are the most knowledgeable defense firm that I am aware of, having actually written the book on DWI Defense. If you are faced with a DWI you will not find a more professional and skilled law firm. But, most importantly, they care about how the accused individual recovers his or her life when the case is complete. Very remarkable group of lawyers. William H.
