Breathalyzer tests are the tests used in drunk driving or DUI cases when the officer attempts to collect a breath test sample from you at the police station. Currently the device used is called the Intoxilyzer 5000, which is a rather large boxlike machine.

There are also portable breath testers (also called breathalyzer devices) available for purchase that you can get to test yourself or others. Some people purchase these to prevent themselves from getting a second DUI by testing themselves anytime they have a drink to make sure they are not over the legal limit if they intend to drive. Others just get them as party favors or amusing toys to have around while drinking to see how high their blood alcohol level gets.

Some Breathalyzer Facts

What’s not commonly known is that there is some pretty conclusive evidence that shows that breathalyzer tests vary on average by about 15% from what a person’s actual blood alcohol concentration is. And at least 1 out of every 4 persons tested will show a blood alcohol concentration (BAC) level higher than their actual BAC.

What this means is that when you convict a suspected drunk driver on only the basis of a breathalyzer test then you are convicting an innocent person about 25% of the time. So as you can see breathalyzer tests do not give precise readings they can only give general levels of intoxication with a plus or minus percentage of error. That is the basis for a lot of controversy surrounding DUI cases nationwide as people challenge the results of their breathalyzer test and subsequently their DUI charge.
