DUI Breath Test

Arizona - DUI Breath Test

In Arizona, in some cases breath tests are used to determine the blood alcohol content (BAC) level of drivers suspected of driving drunk. Since alcohol is absorbed into the blood and blood flows through the lungs, alcohol is present in the lung’s air sacs. A breathalyzer works on the assumption that the concentration of alcohol in the breath is a function of the concentration of alcohol in the blood.

Rather than ask drivers to submit to invasive, impractical blood or urine tests in the field, many law enforcement agency's use breath tests as a means for determining the blood alcohol level of drivers suspected of DUI in Arizona.

The Officer Told Me to Blow Harder – Can the Test be Trusted?

Despite what Arizona DUI police officers say, scientific research indicates breath tests are not as accurate or as dependable as claimed. Because they depend on the amount of alcohol in the air sacs of the lungs, variations in breathing can affect the results. For instance, deep breaths will capture air from deep in the lungs where the concentration of alcohol is greater. Likewise, short, quick breaths will capture less air from deep in the lungs, providing air less affected by the concentration of alcohol in the blood.

I Know I Wasn’t Drunk but I Failed the Breathalyzer Anyway

How a person breathes into a breathalyzer can affect the results. More often than not, Arizona police officers ask suspects to take deep breaths and blow hard into a breathalyzer. Doing this may artificially inflate the results, thus leading to an inaccurate indication of one’s blood alcohol level. Secondly, a breathalyzer may not be calibrated correctly. Arizona police departments should have a maintenance record for each of their machines to indicate whether they have been properly checked and kept in good working order.
