Interfering Substances and DWI

Law enforcement officers have many methods for determining the sobriety of individuals whom they suspect of driving under the influence of alcohol, including field sobriety tests and breathalyzer analysis. Unfortunately, there are certain substances that can interfere with the breathalyzer machine’s readings, making it appear that the person had consumed alcohol when he or she did not.

A false reading on a breathalyzer machine may result in criminal charges of DWI or DUI against the individual and the individual may be forced to deal with serious consequences as a result. If you or someone you love is facing DWI charges, contact Dallas DWI attorney Mark T. Lassiter at (214) 845-7007.

Breathalyzer Testing and Interfering Substances

Studies show that certain substances can interfere with breathalyzer tests, including:

  • Throat lozenges
  • Listerine
  • Throat sprays
  • Paint fumes
  • Ethanol-based products

Persons who have ingested certain products or substances may be falsely accused of being intoxicated during field sobriety testing. Persons who have been falsely accused should be sure to have an experienced DWI lawyer on their side to help defend their rights and protect their livelihood. If your breathalyzer results were affected by an interfering substance, you may be able to show that the charges against you are false.
