Proof of Intoxication

Proof of Intoxication in New Jersey DWI Cases

Driving while intoxicated (DWI) offenses in New Jersey are very serious, even if it is a first offense. A DWI conviction can have significant consequences, including license suspension and jail time that can impact several aspects of your life including educational and employment opportunities. If you have been charged with a DWI, you should speak with an experienced attorney as soon as possible to help you navigate the legal process and get you the most desirable result in your case.

Two are also instructors in Standardized Field Sobriety Testing (“SFST”), the alternative basis used by police officers to prove intoxication.

Proof of Intoxication in a New Jersey DWI Case

Police officers can obtain proof of intoxication by several different methods. These include:

I. Breath Test Readings: Alcotest 7110 Breath Testing Device

The most common test used by the police in proving intoxication is the breath test machine, the Alcotest 7110 which is manufactured by Draeger Safety. This test gets breath samples from those suspected of driving while intoxicated and tells the officer what the persons blood-alcohol content is. As mentioned above, one of our attorneys, Travis Tormey, is trained on the device’s analytical system, components, peripherals, and how to operate the machine and perform a New Jersey specific breath test sequence. This allows us to very effectively attack the prosecutions case if there were any problems with the machine or if the tests were faulty in any way.

II. Observation of Officer

A state can also show proof of intoxication based on what the officer observes. These observations can include:

Watery or bloodshot eyes

Slurred speech

Smell of alcohol

Admissions by the suspect

The police officer can also make observations based on how the person performs on any of the field sobriety tests. These tests are approved by the National Highway Traffic Safety Administration (“NHTSA”). The three most common tests are:

Horizontal Gaze Nystagmus (“HGN”) Test

Walk and turn test

One leg stand test

Although these are the three main tests, the HGN test has not been shown to be scientifically reliable in courts. However, it can be used as probable cause for a DWI stop. Other tests that might be administered by the officer are:

Counting backwards and forwards

Head tilt test

Finger to nose test

Reciting the alphabet

Note: Sometimes, the State might not have an admissible breath test reading. However, even if there is a problem with the reading, the prosecution can still prove a DWI by performance on the field test and these observations of police officers.
