Key Factors That Affect Your NJ DWI Case
- BAC thresholds & testing — NJ’s 0.08% per se rule, harsher rules for CDL (0.04%) and under-21 (0.01%).
- Implied Consent Law — In New Jersey, simply driving means you agree to submit to a breath test if suspected of DWI. Refusal carries separate penalties under [N.J.S.A. 39:4-50.4a], including license suspension and surcharges, even if you weren’t intoxicated. See our [Refusal to Submit to a Breathalyzer] page.
- Aggravating factors — A high BAC (≥0.15%), refusing a breath test, causing a crash with injuries, or driving with a minor passenger can all result in increased penalties. Note: New Jersey’s separate “school zone” DWI enhancement was repealed in 2019, though DWIs near schools may still be prosecuted under related statutes (such as assault by auto or child endangerment).

The DUI/DWI Court & Arrest Process in NJ
The legal process always begins with an arrest. Police officers will administer an Alcotest to determine blood alcohol concentration, and if you refuse, you could face separate penalties. The process then continues in municipal court with arraignment, possible motions, and resolution through a bench trial.
Many cases are resolved within 60 days; however, timelines vary depending on the complexity. The process can be significantly extended if a convicted driver’s appeal is successful.

New Jersey DUI & DWI Defense: FAQs
Record & Expungement
How long does a DUI/DWI stay on my record in NJ?
A DWI conviction stays on your driving record permanently. Unlike other offenses, it cannot be erased with time.
Can my DUI/DWI be expunged in NJ?
No. A DWI cannot be expunged under New Jersey law because it’s classified as a traffic offense rather than a criminal conviction.
How does a DUI/DWI affect my insurance rates?
Most drivers see their premiums double or triple after a conviction. In addition, the NJ Motor Vehicle Commission imposes mandatory surcharges of $3,000–$4,500, and some insurers may even drop coverage.
Arrest & Court Process
What happens after a DUI arrest in New Jersey?
You’ll be processed, given a municipal court date, and required to appear before a judge.
Can I still drive while my DUI case is pending?
Yes. In most cases, you can drive until sentencing, when a judge may suspend.
Can I get a jury trial for a DUI/DWI in NJ?
No. DWI cases are heard only in municipal court before a judge; jury trials are unavailable.
BAC, Testing & Refusal
What is the legal BAC limit in New Jersey?
- 0.08% for standard drivers
- 0.04% for CDL drivers
- 0.01% for drivers under 21
What is a per se violation?
It means you are legally intoxicated just by exceeding the BAC limit, even if there’s no evidence of actual impairment.
Should I refuse a breath or field sobriety test in NJ?
- Field sobriety tests are voluntary, but refusal may raise suspicion.
- Breath tests (Alcotest) are mandatory under NJ’s implied consent law. Refusal carries separate penalties equal to or greater than a DWI conviction.
What is an Alcotest, and can it be challenged in court?
The Alcotest is New Jersey’s official breath-testing device. Results may be challenged if it was improperly calibrated, mishandled, or influenced by certain medical conditions.
Penalties & Defenses
Can I avoid jail for a first-time DUI/DWI in NJ?
Often yes. First-time offenders usually face fines, license suspension, ignition interlock, and alcohol education programs — but jail time is rare unless aggravating factors exist.
What is the 10-Year Step-Down Rule?
If 10 or more years pass between convictions, the new charge may be sentenced as if it were one level lower than the original charge.
What defenses can reduce or dismiss a DUI/DWI charge?
Common strategies include:
- Challenging the traffic stop or officer conduct
- Questioning Alcotest accuracy or procedure
- Using medical conditions to explain BAC readings
- Negotiating alternative sentencing or dismissal
Special Categories
What happens if I’m under 21 and charged with DWI in NJ?
Drivers under 21 face zero-tolerance penalties for any BAC ≥0.01%, including license suspension, fines, and alcohol education.
What if I’m a commercial driver with a CDL?
CDL holders face a 1-year CDL suspension for a first offense (0.04% BAC or higher), and a lifetime ban for a second offense.
What if I’m an out-of-state driver charged with DUI/DWI in NJ?
New Jersey reports the conviction to your home state through the Driver’s License Compact, and penalties (including suspension) usually follow you home.
