Q: How can I challenge the accuracy of a breathalyzer device?

A:

To challenge the accuracy of a breathalyzer device in California, several legal avenues may be pursued. One common approach is to question the calibration and maintenance records of the device. Breathalyzers must be regularly calibrated and maintained according to specific protocols to ensure their reliability. If there is evidence showing that the device was not properly calibrated or maintained, it could cast doubt on the accuracy of the test results.

Another factor to consider is the training and certification of the officer administering the breath test. The officer must be adequately trained in the use of the breathalyzer and follow proper procedures during administration to ensure accurate readings. If the officer failed to comply with these requirements, this could also form a basis to challenge the results.

Additionally, the physiological factors affecting an individual’s breath can be relevant. Issues such as the presence of certain medical conditions, the timing of the test, and the consumption of specific substances can all potentially affect breathalyzer accuracy. Presenting expert testimony on these matters can strengthen a defense. It is advisable to consult with a legal professional to navigate these complexities effectively in the context of a DUI case.
