Below, we will explain how Breathalyzer and field sobriety tests can be challenged in court and how we can help you navigate this complex process.
Understanding Breathalyzer Tests
Breathalyzer tests are commonly used by law enforcement officers to measure a driver’s blood alcohol content (BAC). When you are stopped for suspected drunk driving, the officer may ask you to take a breath test to determine whether your BAC is above the legal limit, which is typically 0.08 percent. However, the accuracy of these tests can be questioned in certain circumstances.
One of the main issues with Breathalyzer tests is that they are not always accurate. Several factors can interfere with the results, including the device itself, how it is calibrated, or how it was used by the officer. Breathalyzer machines require regular calibration to ensure their accuracy. If the machine is not properly maintained or calibrated, the results of the test could be incorrect. Additionally, the officer must follow strict procedures when administering the test. If these procedures were not followed, it could result in an inaccurate reading.
Moreover, your medical condition or certain substances in your body, such as mouthwash or medication, can also affect the Breathalyzer reading. These factors could lead to false positives, showing a higher BAC than you actually have. If any of these issues arise, your attorney may be able to challenge the results of the Breathalyzer test in court.
Challenging Breathalyzer Results in Court
There are several ways in which Breathalyzer test results can be challenged in court. One approach is to question the accuracy of the machine itself. If the Breathalyzer was not properly calibrated or maintained, it may not have been functioning correctly at the time of the test. Your attorney may seek to prove that the equipment used was faulty or unreliable.
Another common defense is to argue that the officer did not follow proper procedures when administering the test. For example, officers must ensure that a certain amount of time passes between the moment of the alleged offense and the moment the test is administered. If this timing requirement was not met, it could invalidate the test results. Additionally, if the officer did not observe you for the required period before administering the test, it may be possible to argue that the results are unreliable.
In some cases, your lawyer may also challenge the accuracy of the BAC reading by presenting medical evidence or arguing that external factors, such as medications or mouthwash, could have influenced the test results. If any of these issues are present in your case, it could be grounds for a successful challenge in court.
The Role of Field Sobriety Tests
Field sobriety tests are another tool that law enforcement officers use to assess whether a driver is under the influence of alcohol or drugs. These tests are typically administered at the scene of the stop and involve a series of physical tasks, such as walking in a straight line or standing on one leg. The goal is to evaluate a person’s coordination and balance, which can be impaired when under the influence.
While field sobriety tests are often used as evidence in DUI cases, they are not foolproof. Like Breathalyzer tests, they can be influenced by a number of factors that may not have anything to do with alcohol or drugs. For example, a person may have physical conditions such as vertigo, back problems, or knee pain that could affect their performance on the tests. Additionally, environmental conditions, such as poor lighting or uneven ground, can make it difficult to complete the tests successfully, even for someone who is sober.
If you believe that the field sobriety tests were not administered properly or that your performance was affected by an unrelated condition, it may be possible to challenge the results in court. Your lawyer can look into whether the tests were conducted in a fair manner and whether any factors outside of alcohol or drugs played a role in your performance.
Challenging Field Sobriety Tests in Court
There are several ways that field sobriety test results can be contested in court. One of the first things your lawyer will consider is whether the officer followed the proper procedures when administering the tests. Law enforcement officers are required to follow strict guidelines when conducting these tests. If the officer failed to administer the tests in the proper order or did not use the correct instructions, it could undermine the validity of the test results.
Additionally, your attorney may be able to argue that external factors, such as medical conditions or environmental conditions, played a role in your performance on the field sobriety tests. If you have a medical condition that affects your balance or coordination, this could explain why you failed the tests even if you were not under the influence of alcohol or drugs. Similarly, if the tests were conducted on uneven ground or in poor lighting conditions, this could have made it difficult for you to complete the tasks successfully.
In some cases, your lawyer may argue that the field sobriety tests are inherently unreliable and should not be used as evidence in your case. There is ongoing debate in the legal community about the accuracy and fairness of these tests, and in some jurisdictions, field sobriety tests are not given as much weight in DUI cases. If your attorney is able to challenge the validity of the field sobriety tests, it could weaken the prosecution’s case against you.
