Short answer
Yes. New Jersey can pursue DWI based on evidence that a person operated a vehicle while impaired, even without an admissible breath-test result. Police observations and other admissible evidence may matter, but the State must prove the charge beyond a reasonable doubt. Excluding a test result does not automatically dismiss the whole case.

What are the two different ways alcohol DWI can be proved?
N.J.S.A. 39:4-50 addresses both operation while under the influence and operation with a blood alcohol concentration of 0.08% or more. The numeric route and the impairment route raise different evidence questions. This article concerns the general alcohol-DWI provision, not the separate rules for underage or commercial drivers.
Do not equate the absence of a number with the absence of a case. Equally, an officer's accusation is not itself a finding of guilt.
What observations may be part of the evidence?
The evidence may include testimony about driving, speech, balance, coordination, and performance on roadside tests, together with recordings and other admissible material. A defense review considers the reliability and context of those observations, including whether video supports the description and whether a medical condition or injury supplies another explanation.
These are subjects for investigation, not automatic defenses. The court must assess the evidence as a whole and apply the burden of proof.
What does State v. Kuropchak actually show?
In State v. Kuropchak, the New Jersey Supreme Court examined both breath-test evidence and observational proof. It found problems with the admission of the test and certain police reports and remanded for a new trial. The decision illustrates why challenging one piece of evidence and obtaining a final dismissal are different things.
That 2015 decision is not a promise about a current case or a checklist for every testing instrument. The device, records, testimony and law applicable to your case need their own review.
Does a missing result mean there was a refusal?
Not necessarily. Why no result exists matters. A separate refusal charge has its own legal requirements; it should not be inferred merely from an empty space in the paperwork. Our breath-test refusal guide discusses that separate issue.
If your case involves the Alcotest 9510, read the 9510 guide and have counsel identify the instrument and the records actually used. This article is not advice to refuse testing.
What should a case review examine?
- The complete summonses and the reason a test result is missing or disputed.
- Available body-camera, dashboard-camera and station recordings.
- Reports describing the stop, alleged operation and roadside observations.
- Medical or physical issues relevant to the specific observations, discussed privately with counsel.
- Whether any other testing, witnesses or separate charges are involved.

Frequently asked questions
Is a DWI automatically dismissed if the breath test is excluded?
No. The State may still have an impairment case based on other admissible evidence. The remaining proof must satisfy the beyond-a-reasonable-doubt standard.
Can medical issues matter when reviewing roadside observations?
They can be relevant to a particular observation, but they do not automatically defeat the charge. Discuss the records and facts privately with counsel.
