I strongly disagree. There are non-alcoholic things that can be consumed or used that will provide false positive readings with a Breathalyzer when talking about a level as low as what AJ blew.

I have heard that most mouthwashes/rinses, because they contain alcohol, can cause a positive low reading. I don't know if this is true or not; maybe someone can provide some documentation one way or the other.

Alcohol in your mouth, that is not in your bloodstream, can result in the machines showing that there is alcohol in the test subject's system when there may not be. This is known as mouth alcohol. The forensic alcohol analysts that I've worked with seem to agree that within 5-6 minutes of ingesting an alcoholic substance the mouth alcohol is gone and any breath alcohol level will correspond to a blood alcohol level.

So yes, the machines CAN be fooled. However, proper testing procedure involves a minimum 15 minute observation period prior to the first blow to make sure that the test subject has not eaten or drank anything, burped, regurgitated, or vomited. The observation/waiting period serves to eliminate any tainted results.

If the proper testing procedures are followed, the machines are accurate. No doubt in my mind.

Not trying to be disrespectful, but how does a tester know if a testee has burped in the last 15 minutes? And, is each randomly chosen driver for these tests observed for 15 minutes prior to testing to make sure they didn't burp?

If you have access to what ever type of Breathalyzer is being used (hand held or tabletop) to test drivers, please access one. Suck on a Certs and then test yourself. I think you might be surprised.
