Five Factors Courts May Consider in Determining Whether a Driver Was Impaired in a New Jersey DWI Case
A common misconception in driving while intoxicated (DWI) cases involves breath testing and blood alcohol content (BAC). New Jersey’s DWI statute states that a person who operates a vehicle with a BAC of 0.08 percent or higher commits a violation, but this is not the only way the state can prove intoxication or impairment. The statute actually defines the offense in two ways: driving with a BAC above a minimum amount, or driving “under the influence” of alcohol or other drugs. Even without any BAC evidence, prosecutors may still be able to prove that a defendant was “under the influence,” intoxicated, or otherwise impaired. The Appellate Division of the New Jersey Superior Court issued a ruling several months ago in State v. Kessler, which identified various methods of presenting evidence of intoxication or impairment.
A police officer pulled the defendant over at about 1:22 a.m. He had allegedly observed the defendant swerve from the left lane of the highway into the center lane, putting him in the path of a tractor-trailer. He also claimed that the defendant was driving without his headlights on. The officer testified that the defendant’s eyes appeared “bloodshot and watery,” and the officer could smell alcohol. The defendant allegedly refused to submit a breath sample and did not perform well on several field sobriety tests (FSTs).
The defendant was charged with DWI, refusal to submit to breath testing, reckless driving, and other offenses. At trial in the municipal court, the defendant presented testimony from several expert witnesses. One witness testified about difficulties faced by some people on the horizontal gaze nystagmus (HGN) test. Another witness testified about conditions, both congenital and injury-related, affecting the ability to perform FSTs like the walk-and-turn and one-leg-stand tests. The defendant denied drinking any alcohol on the night of his arrest.
