Factors that can contribute to false breathalyzer readings

On Behalf of | Mar 29, 2024 | Criminal Defense

Getting behind the wheel while under the influence of alcohol is dangerous. Law enforcement agencies across Texas go to great lengths to combat the drunk driving problem here. When an officer suspects that a driver is under the influence of alcohol, they often use sobriety tests like Breathalyzers to determine the driver’s sobriety. However, Breathalyzers are not always accurate and may give false readings. Here are some factors that may cause false Breathalyzer results.   


Acetone is a type of ketone in the body and is a byproduct of the way the body breaks down food. Acetone has a fruity or sweet odor and may be present in the breath of anyone. Acetone in an individual’s breath can give a false blood alcohol concentration reading in Breathalyzers. That could result in the individual being wrongly charged with driving under the influence. 


A low-carb diet has been shown to increase acetone levels because the body produces more acetone to compensate for reduced glucose levels. The Atkins diet and similar low-carb diets seek ketosis, which causes more fat-burning. Ketones create alcohol and this can turn into high levels of acetone.

Unfortunately, even a Breathalyzer test that gives a false reading can still result in the driver being accused of intoxication. Those in Texas who have been accused of DWI or DUI have the right to secure legal representation to defend against the accusations. A trusted criminal defense attorney experienced with DUI cases can focus on safeguarding the rights of those charged and guide them through this frustrating experience.
