What is BAC and How is a DWI / DUI Proven in New Jersey
A DWI (Driving While Intoxicated) or DUI (Driving While Under the
Influence) charge is proven by your blood alcohol concentration (BAC).
Your BAC can be tested with a simple Breathalyzer, Alcotest, or Blood
test.

In New Jersey, a person with a BAC of 0.08% or greater who operates a motor vehicle or a
boat is considered to be driving under the influence (DUI).   Being convicted of a DUI or DWI
is a serious offense, carrying heavy penalties including:   Fines, fees, surcharges, Jail
time and Community service.

Each persons body absorbs alcohol at a different level and the rate of absorption varies even
in the same individual at different times of the day.  (example most peoples bodies will absorb
alcohol quicker in the mid day and much slower in the late night hours)  Generally, the average
rate of “burn off ” or elimination of alcohol is .015 in an hour which is much less than most
people think and thus the reason why many people are surprised when a police officer asks
them to step out of the car for the DWI tests.

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 evaluate 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.  BAC can
also be determined by physical tests.  In New Jersey 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.
