Q: Can I challenge the accuracy of a breathalyzer machine?

A:

Yes, you can challenge the accuracy of a breathalyzer machine in California. The defense may argue that the breathalyzer readings are not reliable due to a variety of factors. For instance, breathalyzer machines require regular calibration and maintenance. If the machine has not been properly maintained or calibrated according to state regulations, this can be a basis for challenging the accuracy of the test results.

Additionally, the accuracy of a breathalyzer can also be affected by a number of physiological factors such as the individual’s breathing patterns, the presence of certain medical conditions, and the time elapsed between driving and testing. If a defendant can demonstrate that these factors may have influenced the results, it may undermine the prosecution’s case.

In the context of DUI offenses, a skilled attorney can utilize expert testimony on the operation of breathalyzer devices and the science behind breath alcohol measurement to build a defense. This may include questioning the qualifications of personnel administering the test and whether proper testing protocols were followed. Therefore, if you believe there are valid concerns regarding the breathalyzer’s accuracy, you should consult with a legal professional for a thorough evaluation of your specific circumstances.
