While breathalyzers are frequently used in DUI cases to indicate the intoxication level of the accused driver, they are not completely accurate. If you are facing a drunk driving charge, it’s important to understand when breathalyzers can provide false readings. It could be the difference between having the charges dismissed and spending time behind bars.

What Causes Inaccurate Breathalyzer Results?
A study by the National Motorists Association found a 50 percent margin of error when comparing breathalyzer results to actual blood alcohol content. In fact, a number of contributing factors can cause an inaccurate breathalyzer reading, such as:
- Improper machine calibration
- Operator error
- Breathing rate
- Body temperature
- Certain prescription medications
- Low-carb diets
- Acid reflux
Officers know that breathalyzers are vulnerable to error. Because of this, some will try to obtain a consistent result by taking several readings. However, even multiple readings cannot guarantee accurate results.
When Should You Challenge Breathalyzer Results?
Challenging the accuracy of a breathalyzer test may not help your case if the results were significantly higher than the 0.08% legal blood alcohol limit. But if you blow just slightly over the legal BAC limit, an argument could be made that your results are inaccurate, and your case could get thrown out.
The best way to determine whether your breathalyzer results should be challenged is to discuss your case for free with an experienced DUI lawyer at the Gordon Law Firm, PC. We have the skill, resources, and successful track record you can trust to build your strongest defense.
