Proof of Intoxication in a New Jersey DWI Case

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

1) 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.

2) Observation of Officer

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

  1. Watery or bloodshot eyes
  2. Slurred speech
  3. Smell of alcohol
  4. 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:

  1. Horizontal Gaze Nystagmus (“HGN”) Test
  2. Walk and turn test
  3. 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:

  1. Counting backwards and forwards
  2. Head tilt test
  3. Finger to nose test
  4. 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.
