Products that Can Cause False Breathalyzer Results
Drivers who are suspected being under the influence of alcohol are typically required to submit to a breathalyzer test in order to assess their level of inebriation while in the field.. People who have been convicted of a DUI may be legally required to breathe into an ignition interlock device, which will stop their car from starting if they blow above a .02 or 04. These tests are imperfect, however, and certain products consumed or imbibed shortly before breathing into a breathalyzer can produce a false reading, potentially bringing about serious consequences.
If you have been accused of driving while intoxicated, whether due to a false breathalyzer reading or otherwise, Rhode Island drunk driving defense attorney James Powderly can help you to protect your legal rights and interests. Contact him by calling 401-662-9006 to discuss your case.
Sources of False Readings
A breathalyzer works by measuring the concentration of certain chemicals in the condensate produced by his or her breath. Substances which one might imbibe, ingest, or place in the mouth can have a significant influence on a breathalyzer reading, and if they contain the chemicals which a breathalyzer evaluates, a suspect’s BAC may appear to be artificially elevated. Some products that may cause false readings indicating inebriation include:
- Mouthwash, such as Listerine
- Certain medications, such as Nyquil, albuterol, and budesonide
- Certain bread products in dense amounts
