The Problems with New York DWI Alchemy: Turning Breath into Blood

You know, New York State is a blood state. That does not mean that NYS is out for blood although with our taxes that is not an unfair statement... Whether the police decide to request your blood or just your breath, in the end it all comes down to a BAC. What I mean is that when it comes to a DWI “per se” charge, driving while intoxicated New York DWI laws that focus upon a measured quantity of alcohol are all based upon Blood Alcohol Concentration. This is true even when a breath test is used to measure your BAC.

Our Vehicle and Traffic Law statute section 1192 gives two BAC based criminal charges. A DWI based upon a .08 BAC or higher or the more serious Aggravated DWI where your blood alcohol concentration level was .18 BAC or higher. These are blood numbers not breath numbers. If they were breath they would be "BrAC" not BAC.

Different DWI Breath Testing Machines but One Methodology

The problem is that depending upon where you are arrested in New York State you might have been tested with one of three types of breathalyzers. In the city, the New York City Police Department has the Intoxilyzer 8000, while the upstate police departments within the cities, towns, and villages have the Datamaster DMT, and lastly our state troopers (around the state highways) all use the newest breath machine, the Draeger Alcotest 9510.

So what do all these breathalyzers all have in common?

They all take a breath sample to measure your body’s alcohol level --not a blood sample. The reading off the unit is in BAC not a BrAC. It doesn’t give your breath alcohol concentration measurement, it gives your BLOOD alcohol measurement.

Which means that for the most part the majority of chemical testing for DWI in New York State is INDIRECT alcohol testing of your blood. The machines take in a breath alcohol sample, and then spits out a blood alcohol measurement.

Changing a Breath Alcohol Measurement to a Blood Alcohol Measurement

The breathalyzers all have software that runs a program to do this calculation of changing breath alcohol into a blood alcohol concentration. The breath testing software, and it’s algorithms are all secret. To do this calculation the machine must assume a great many things about you: like what your ratio of breath to blood is, what your body temperature is, what your elimination rate for alcohol is, etc, etc

The Questions that Arise from Indirect Measurements of Blood

So much doubt resides between what you give the machine as your breath alcohol sample, and what the machine actually calculates as a BAC number. This is where your true guilt or innocence may reside.

Can we trust an indirect number? Can we fully trust the results of a one-time sample? Can a judge or jury decide your fate beyond a reasonable doubt without more than that? Can they? The answer is yes, but should they? the answer is a most definite NO.


In any New York breath test DWI, the importance of looking at everything in the totality of the circumstances is something every defense must highlight. We cannot allow judges or juries decide the fate of a person based upon this type of testing alone. The DWI chemical testing of breath, one time, indirectly calculated to measure blood alcohol concentration, and based upon an average person is not the making of justice.
