If you're searching "DUI vs DWI in NJ," you may be surprised to learn that New Jersey only has one impaired driving charge — and it's called DWI. Here's what that means and how it affects your situation.
Short answer: New Jersey has no separate DUI charge. All impaired driving offenses — whether alcohol or drugs — are prosecuted under the same statute: N.J.S.A. 39:4-50, known as the DWI law. When people say "DUI" in New Jersey, they mean DWI. The terms are used interchangeably in everyday conversation, but only "DWI" exists in NJ law.
Most states use both "DUI" (Driving Under the Influence) and "DWI" (Driving While Intoxicated) as separate charges — sometimes at different severity levels or BAC thresholds. New Jersey consolidates everything into one statute. N.J.S.A. 39:4-50 covers:
All of these fall under the single heading of "DWI" in New Jersey. There is no DUI statute, no separate drug-impaired driving charge, and no "DWAI" (Driving While Ability Impaired) category as exists in New York. Everything goes through the same law, the same courts, and the same penalty structure.
| State | Alcohol Charge | Drug Impairment | Lower BAC Offense |
|---|---|---|---|
| New Jersey | DWI (N.J.S.A. 39:4-50) | Same DWI statute | Covered under same statute if impaired |
| New York | DWI (0.08%+) | DWAI-Drugs (separate) | DWAI (0.05–0.07%) |
| Texas | DWI | DWI (same statute) | DUI (minors only) |
| California | DUI (VC 23152(b)) | DUI (VC 23152(f)) | No separate lower offense |
| Florida | DUI | DUI (same statute) | No separate lower offense |
The takeaway: when you read articles from other states about "DUI vs DWI" differences, those distinctions don't apply in New Jersey. If you were charged in NJ, you were charged with DWI — period.
One area where NJ residents often expect a separate "DUI" charge is drug-impaired driving. In many states, drug impairment is a different statute. Not in New Jersey.
If a New Jersey officer suspects you're driving under the influence of marijuana, prescription medication, or any other substance, the charge is still DWI under 39:4-50. The difference is evidentiary: alcohol cases rely primarily on breathalyzer results (Alcotest readings), while drug impairment cases typically involve a Drug Recognition Evaluator (DRE) — an officer trained in 12-step drug impairment assessment — plus blood or urine testing.
The penalties are the same as an alcohol DWI. First offense drug DWI in NJ: up to 30 days jail (rarely imposed), license suspension, fines and surcharges, and ignition interlock in many cases. The conviction appears on your driving abstract the same way as alcohol DWI.
This is one of the most important distinctions in NJ DWI law — and one that directly affects how you should think about your situation.
New Jersey DWI is a traffic offense, not a criminal charge. It is prosecuted under the Motor Vehicle Code, not the Criminal Code. This has several significant practical implications:
This is a meaningful difference from states where DWI/DUI is a misdemeanor or felony criminal charge. In NJ, the consequences are serious — but they're civil/administrative rather than criminal in nature.
Since NJ has one unified DWI charge, the penalty structure applies to all offenses — alcohol and drug alike — with the primary distinction being BAC level for alcohol cases:
| Offense | License Suspension | Fine Range | Ignition Interlock |
|---|---|---|---|
| 1st Offense (BAC 0.08–0.09%) | 3 months | $250–$400 | Required (6 months) |
| 1st Offense (BAC 0.10%+) | 7–12 months | $300–$500 | Required (9–15 months) |
| 2nd Offense | 2 years | $500–$1,000 | Required (2–4 years) |
| 3rd Offense | 10 years | $1,000 | Required (10 years) |
All offenses also carry surcharges of $1,000/year for 3 years (first and second offense) or $1,500/year for 3 years (third+), plus IDRC (Intoxicated Driver Resource Center) program requirements and court costs.
This is one of the most common follow-up questions after a DWI conviction. The answer is no — and the reason ties directly to NJ's classification of DWI as a traffic offense.
New Jersey's expungement statute (N.J.S.A. 2C:52-1 et seq.) applies to criminal convictions. Since DWI in NJ is a traffic offense rather than a criminal charge, it falls outside the scope of expungement law. A DWI conviction remains on your NJ driving abstract permanently. It cannot be sealed, expunged, or removed through any standard legal process.
There is one narrow exception: if your DWI charge was dismissed or you were acquitted, there is no conviction to expunge and the record may be handled differently. But a conviction — guilty plea or trial finding — stays on the abstract.

Request a Free ConsultationNo. New Jersey does not have a separate DUI statute. All impaired driving offenses — alcohol or drugs — are charged under N.J.S.A. 39:4-50 as DWI. If you were stopped for impaired driving in NJ, the charge is DWI regardless of the substance involved.
They mean DWI. Many people use DUI as a generic term for impaired driving regardless of state, and New Jersey residents often say "DUI" when they mean they were charged with DWI under NJ law. The legal charge is always DWI in this state.
Because NJ DWI is a traffic offense — not a criminal conviction — it generally does not appear on standard criminal background checks. It does appear on your NJ motor vehicle driving abstract. Certain employers (transportation, healthcare, financial services) may specifically request driving records, where the DWI would be visible.
Your NJ DWI case is handled in NJ municipal court regardless of where you live. A conviction will be reported to your home state's licensing authority through the Interstate Driver License Compact (which most states participate in), and your home state may impose its own penalties on top of NJ's.
The statutory penalties are the same. However, drug DWI cases often involve more complex evidence (DRE evaluation, blood/urine testing), which can create different defense opportunities. The process and some practical implications may differ even though the charges carry identical penalties.
