Why Is Breathalyzer Calibration Important for DUI Defense?


Breathalyzer tests are a common tool used by law enforcement to determine if a driver is under the influence of alcohol. However, these tests are not foolproof and can often produce inaccurate results if the device is not properly calibrated. In this blog post, we will discuss the importance of breathalyzer calibration in DUI defense and provide useful tips for those facing DUI charges.

1. Understanding Breathalyzer Calibration

Breathalyzer calibration refers to the process of ensuring that a breathalyzer device is working properly and accurately measuring the alcohol content in a person's breath. Calibration is essential to ensure that the device is functioning within the manufacturer's specifications and providing accurate results.

2. The Consequences of Inaccurate Results

Inaccurate breathalyzer results can have serious consequences for those facing DUI charges. A falsely high reading can result in a conviction and all the associated penalties, including fines, license suspension, and even jail time. It is important to ensure that the device is properly calibrated to avoid these consequences.

3. How to Challenge Breathalyzer Results in Court

If you have been charged with a DUI based on breathalyzer results, it is important to understand that these results can be challenged in court. One way to challenge the results is to question the calibration of the device. If it can be shown that the device was not properly calibrated, the results may be deemed inadmissible in court.

4. The Role of a DUI Defense Attorney

A DUI defense attorney can play a crucial role in challenging breathalyzer results and ensuring that your rights are protected throughout the legal process. An experienced attorney can review the calibration records of the device and determine if there are any issues that could be used to challenge the results in court.

5. Ensuring Proper Calibration of Breathalyzer Devices

To ensure that breathalyzer devices are properly calibrated, it is important to have them checked regularly by a qualified technician. Law enforcement agencies are required to maintain calibration records for their devices, and these records can be obtained through a public records request.

Breathalyzer calibration is a critical factor in DUI defense. It is important to understand the consequences of inaccurate results and how to challenge these results in court.
