3 common myths about tricking a Breathalyzer test 

On Behalf of | Sep 20, 2021 | Criminal Defense

There are several myths in circulation that commonly lead drivers to the misconception that Breathalyzers can be tricked. The most frequently asserted misapprehensions involve placing a penny under your tongue, rinsing your mouth out with water or mouthwash and holding your breath. 

Crucially, none of these methods work. Therefore, it is vital to explore the common misconceptions regarding Breathalyzers and how the law in Alabama expects you to behave as a road user. 

Sucking on a penny

It is a common misperception that the copper and zinc contained in coins will create a chemical reaction that interferes with Breathalyzer equipment. However, due to the way that Breathalyzers work, this will have no impact at all. Breathalyzer tests measure the concentration of alcohol in a person’s breath. As a result, even if coins did create a chemical reaction, this would not affect test results.  

Using water or mouthwash

Many people believe that rinsing with water or mouthwash before blowing will eliminate alcohol. While this may be the case, it has no bearing on the amount of alcohol that is in your bloodstream. Breathalyzers typically measure the alcohol that diffuses into your lungs. Additionally, many mouthwash products also contain alcohol, which would have a counterproductive effect. 

Holding your breath

Many believe that holding your breath for as long as possible before blowing will reduce alcohol levels. However, the opposite is true. Alcohol passes from your veins to your lungs with every heartbeat, with quantities of it diffusing into your lung cavities. Therefore, alcohol will continue to build in your lungs with each heartbeat until you exhale. 

Understanding the law relating to Breathalyzer tests is in your best interests. Alabama is an “implied consent” state. This means that by merely driving on a public road, you are assumed to have consented to a Breathalyzer test. If you find yourself facing DUI charges, it is vital to know your legal rights and protections.
