Standardized Field Sobriety Testing in Mercer County DWI Cases
There are three tests that have been adopted by the NHTSA as the standard in DWI detection in the United States, including all of New Jersey and Mercer County. Each of these tests is discuss in the headings below:
I. Horizontal Gaze Nystagmus Test (“HGN”). The term nystagmus refers to the involuntary movement of the eye, often in the form of a twitch or lack of smooth tracking. When alcohol is introduced into the human body there is a nystagmus that worsens as BAC gets higher. The HGN test forces a subject to hold their head still and observe an object or stimulus horizontally as it passes from left to right or vice verse. In New Jersey, HGN may only be used as a basis for establishing probable cause to make an arrest. The test may not be used at the time of trial to prove intoxication.
II. Walk & Turn Test. The walk and turn test is the one that many reading this article have seen police officers administrating roadside. It involves requiring the motorist to walk a straight line heal-to-toe without losing balance, using arms for balance and following the instructions in terms of stops and count. The combination of requiring the motorist to utilize his or her motor skills in combination with reciting a step count is referred to as a divided attention test.
III. One Leg Stand Test. The one leg stand is another divided attention test. The test requires the motorist to keep his/her arms at his side and lift one foot approximately six inches off the ground for a count of thirty. Failure to keep the foot in position, such as touching the ground, using arms for balance or failing to recite a proper count is a clue that is potential evidence of intoxication.
