Q: What are common reasons to challenge the accuracy of breathalyzer results?
Common reasons to challenge the accuracy of breathalyzer results include issues related to the calibration and maintenance of the device, improper administration of the test, and physiological factors that may influence the readings. Breathalyzers must be regularly calibrated according to manufacturer specifications to ensure accurate results. If there is evidence that a device was not properly maintained or calibrated, it could be argued that the readings are unreliable.
Additionally, the proper administration of the breath test is crucial. If the test was not conducted following the prescribed procedures, such as not allowing the accused to refrain from consuming food or beverages prior to the test, the results may be questioned. Furthermore, external factors such as the presence of certain medical conditions, medications, or even environmental factors can affect the breathalyzer readings and may serve as grounds for challenging the results.
It is also important to consider the training and qualifications of the officer administering the test. If the officer is not properly trained to operate the breathalyzer or misapplies the operation procedure, the legitimacy of the test results can come into question. All of these factors can contribute to an argument questioning the validity of breathalyzer evidence in DUI cases.
