As we approach the holiday season, parties and alcohol will be as equally present as the increased law enforcement on the road. While it is always the best choice to have a designated driver to take you to and from your festivities, some people choose to drive after having a drink or two. In many cases, taking the precaution of limiting yourself to minimal alcohol leaves you safely under the legal limit. However, Georgia DUI lawyer Mickey Roberts often explains to his clients that if you are stopped and tested by a breathalyzer, you may be accused of drinking far more. How does this happen, and how can you stop it?

As part of the 4 simple rules to remember when stopped by the police to avoid DUI, remember not to submit to any voluntary roadside field sobriety evaluations—breathalyzers included.

In fact, it is advised not to take any state tests if you are arrested, especially if you believe you might be over the legal limit of .08. Unfortunately, even if you do not believe you are over the limit, a breathalyzer may show a very different, incriminating result.




The problem with breathalyzers is the false reading sometimes caused by mouth alcohol. When a breathalyzer analyzes your breath for blood alcohol concentration (BAC), the internal computer believes it is reading from air exhaled from deep within the lungs, also known as alveolar air. However, if your last sip of alcohol was recent, the sample very well may come from your mouth or throat. Even if a very small amount remains, the breathalyzer will report a very high BAC.




Another reason the breathalyzer may report higher than accurate numbers is if the DUI suspect has recently belched or is affected by acid reflux, causing what could be alcohol-filled liquids and gases of the stomach to rise into the esophagus and mouth’s soft tissue, where it remains until it is dissipated by saliva. The action of saliva rinsing the mouth and tissues of alcohol takes roughly 15-20 minutes. An additional cause of inaccurate breathalyzer reading is the usage of mouthwash or breath freshener, which you may be better off not using if you are attempting to cover up the smell of alcohol after consumption. Also, if you have dental work or removable components such as dentures, you are subject to much longer periods of holding high mouth alcohol.




To elude the mouth alcohol problem, it is best to stop drinking—even at minimal levels—hours before driving. To avoid DUI, it is best to always have a designated driver on hand to exacerbate the risk altogether.  If you need DUI help, please Contact MRGADUI  today.  Be sure to follow MrGaDUI on FacebookTwitter and Google+ for more information on Georgia DUI laws.
