Learn What is BAC and How a NJ DWI/DUI Proven
There is a difference between Blood Alcohol Content (BAC) and Breath Alcohol   
Concentration (BrAC). Breath Alcohol Concentration (BrAC) is utilized most often by law  
enforcement to extrapolate or estimate an individual's Blood Alcohol Content (BAC). The best
and most accurate way to determine Blood Alcohol Content (BAC), is through a blood
sample. Since it is very difficult to provide medical personnel to obtain this sample in field
situations (while the officer is determining if an individual is Driving While Intoxicated (DWI) or
Driving Under the Influence (DUI)), breath testing devices are utilized to determine Breath
Alcohol Concentration (BrAC) which typically can be used to equivalate Blood Alcohol
Content (BAC). Breath testing devices rely on an a ratio that equates the parts of alcohol found
in the breath to the correlating amount of alcohol found in blood.  A Blood Alcohol Content
(BAC) of 0.20% means that there is 1 gram of alcohol per every 500 grams of blood.  The
courts of all 50 states have determined that both the Breathalyzer machines and Alcotest
machines are scientifically accurate in determining BAC levels.  The only way to prove the
BAC level taken by the police is inaccurate is by:
1) Proving a BAC test taken within a short period of time after being released by the police
has a substantially different result.
2) Proving that the police operated the machinery incorrectly
3) Proving that the machine used by the police was not operating properly
4) Proving  the machine used to test was operating improperly
5) Proving the machine used was not properly certified
6) Proving the operator of the machine was not properly licensed or had an expired license

If a Breath Test or Blood Test is not given the police may still prove intoxication for a DWI or DUI.  
BAC in this situation can be determined by physical tests.  The most commonly used tests are: The
walk and turn, The one legged stand, Counting numbers or the alphabet, or the HGN Test.  

HGN is the most commonly used test and is commonly known as the  Horizontal Gaze
Nystagmus Test.  The HGN test uses a penlight or a finger which is quickly waved across the
subject’s vision to see that both eyes move in tandem,at about a one foot distant –and the
driver is asked to follow the light or finger with the eyes.   During the HGN Test the police
officer is looking for four indicators of impairment: if the eye cannot follow a moving object
smoothly, if jerking is distinct when the eye is at maximum deviation, is the driver following the
instructions given to hold his head straight without movement, and if the angle of onset of
jerking of the eyeball, instead of smoothly tracking, is within 45 degrees of center.   If, between
the two eyes, four or more clues appear, the suspect likely has a BAC of 0.10 or greater.
