What You're Facing

A traffic offense with criminal-level consequences

In New Jersey, driving while intoxicated (N.J.S.A. 39:4-50) is a motor vehicle offense, not a crime, and DWI and DUI mean the same thing here. Your case will be decided by a municipal court judge, with no jury. What's on the line is anything but minor: possible jail, an ignition interlock device, license forfeiture at higher tiers, mandatory program time and years of insurance surcharges.

N.J.S.A. 39:4-50 reaches several theories: personally operating while under the influence of alcohol or drugs, operating at a BAC of 0.08% or more, and permitting another person to operate a vehicle in the owner’s custody or control while impaired or at the prohibited BAC. The State must prove the charged theory; a breath number is not required for an observational alcohol or drug theory.

You can also be charged with DWI with no alcohol involved at all, since impairment by prescription medication, over-the-counter drugs or marijuana counts too. And if you declined the breath test, you are likely facing a second charge, refusal, with its own penalties. All of it is defensible, and the defense starts with the details of your stop and arrest.

Alcotest 9510 status: On December 19, 2025, the New Jersey Supreme Court dismissed State v. Cunningham after the defendant withdrew her reliability challenge and lifted the limited statewide stay. That procedural order allows affected prosecutions to proceed; it did not decide that the 9510 is scientifically reliable on the merits. An individual defendant may still raise a reliability challenge supported by the case record.

First Offense

First-offense DWI penalties by BAC tier

Since December 1, 2019, a first alcohol DWI is tiered by blood alcohol concentration or the applicable observational theory. The table states the baseline forfeitures, subject to any pre-conviction credit or temporary post-conviction relief for which the statute makes the person eligible. Every tier also carries fines, court costs, a $1,000-per-year insurance surcharge for three years, Intoxicated Driver Resource Center (IDRC) time and the possibility of up to 30 days in jail.

BAC at arrest	License suspension	Ignition interlock	Fine range
0.08% to under 0.10%, or observational alcohol DWI	Until IID installation; MVC notation and licensing eligibility also required	3 months	$250–$400
0.10% to under 0.15%	Until IID installation; MVC notation and licensing eligibility also required	7–12 months	$300–$500
0.15% or higher	3 months following interlock installation	During the forfeiture plus 12–15 months after restoration	$300–$500

Pre-conviction installation is not enough by itself: the driver must obtain the MVC notation and meet the documentation and timing requirements. The pre-conviction waiver applies only to the statutory fine for the applicable paragraph—not court costs, assessments, program expenses or other obligations—and requires a valid New Jersey driver's license in good standing when the offense occurred and continuously through conviction. Pre-conviction two-IID-days-for-one-forfeiture-day credit is limited to the eligible 0.15-or-higher, second, and third-or-later tiers. P.L.2025, c.41 separately permits eligible people to use an IID after conviction in lieu of forfeiture at the same two-for-one rate for offenses occurring on or after April 3, 2025 and before the law expires January 1, 2029. That temporary option does not erase fines, jail, community service, IDRC, assessments or post-restoration IID obligations. It excludes serious-bodily-injury incidents, drug DWI and commercial-motor-vehicle controlled-substance DWI.

One tier the table doesn't show: drivers under 21 are held to a near-zero 0.01% standard under a separate statute, with its own license and community-service consequences — and at 0.08% or higher the adult tiers above apply in full. The details are in our underage DUI guide.

Second & Third Offense

Repeat offenses: where jail becomes mandatory

Prior convictions change everything. Jail stops being a possibility and becomes a requirement, and license loss returns in force.

Second offense

Jail is 48 consecutive hours to 90 days and may not be suspended or served on probation; the sentence also includes one to two years of forfeiture, IID during forfeiture and two to four years after restoration, a $500–$1,000 fine and 30 days of community service. A court may use the county jail, workhouse, an approved inpatient rehabilitation program, IDRC or another approved facility for a first or second jail term. A second offense occurring more than 10 years after the first is sentenced as a first.

Third or subsequent offense

The sentence is 180 days in county jail or a workhouse, an eight-year forfeiture, IID during forfeiture and for two to four years after restoration, and a $1,000 fine. The court may reduce the jail term one day for each day, up to 90 days, in an IDRC-approved substance-use-disorder inpatient rehabilitation program; the third-offense jail term itself may not be served at an IDRC. A third offense occurring more than 10 years after the second is sentenced as a second.

A conviction for a violation of a substantially similar law in another jurisdiction counts as a prior DWI conviction even if that jurisdiction is not part of the Interstate Driver License Compact. N.J.S.A. 39:4-50(a) supplies an express exception: the foreign conviction does not count if the defendant proves by clear and convincing evidence that it was based exclusively on a law prohibiting operation at a BAC below 0.08%. The judgment and foreign statute therefore must be examined rather than treating every out-of-state alcohol-related event as a New Jersey prior.

DWI Questions

What people ask us the night after the arrest

Is a DWI going to give me a criminal record?

No. DWI (N.J.S.A. 39:4-50) is a motor vehicle offense in New Jersey, not a crime (and DUI and DWI mean the same thing here). It is heard in municipal court by a judge alone; there is no jury. That does not make it minor: a conviction can still mean jail, license loss, an ignition interlock, thousands in fines and surcharges, and a permanent mark on your driving record.

Am I going to lose my license on a first offense?

For a first alcohol DWI at 0.08% to under 0.15%, forfeiture lasts until the ignition interlock is installed; lawful operation also requires the MVC notation and licensing or restoration eligibility. The IID period is 3 months below 0.10% and 7 to 12 months from 0.10% to under 0.15%. At 0.15% or higher, the forfeiture is a fixed 3 months following installation, with the IID required during that period and for 12 to 15 months after restoration. Drug DWI has a different forfeiture rule.

Can I ever get a DWI off my record?

New Jersey treats DWI as a motor-vehicle offense rather than a crime, so criminal expungement under Title 2C is not the mechanism for removing it. The conviction remains relevant on the driver history and to later-offense sentencing. The exact abstract and any prior judgment should be reviewed rather than assuming a criminal-record remedy applies.

I refused the breath test. How much trouble am I in?

Refusal is a separate charge under N.J.S.A. 39:4-50.4a with its own IID, fine, IDRC and forfeiture consequences. Implied consent arises from operating on covered New Jersey roads or quasi-public areas, not simply accepting a license. The State must prove the refusal elements beyond a reasonable doubt, including the request, required warning and refusal.

Can my lawyer just plea bargain this down?

The current framework authorizes a plea agreement in a DWI or refusal matter on the prosecutor’s recommendation and with an appropriate factual basis. That does not require an offer or a particular result. Drug DWI and commercial controlled-substance DWI retain the statute’s minimum-forfeiture limits.

What is the IDRC everyone keeps mentioning?

The Intoxicated Driver Resource Center is a mandatory education and screening program for everyone convicted of DWI or refusal in New Jersey, typically 12 to 48 hours for a first offense, with program fees on top of your fines. The IDRC can also refer you for further treatment, and failing to complete it can lead to further license action or jail.

Where is a DWI charge from Mount Holly handled?

A New Jersey DWI is handled in the municipal court for the town where the charge arose. If your complaint names Mount Holly Municipal Court, see our Mount Holly court guide. Shugar Law Office is based at 69 High Street in Mount Holly and represents people in DWI and related municipal matters throughout New Jersey.

Refusal & Drug DWI

Refused the test? Charged after using drugs?

Breath test refusal — N.J.S.A. 39:4-50.4a

N.J.S.A. 39:4-50.2 deems consent from operation on a covered road or quasi-public area when the statutory grounds exist. Refusal is separate from DWI and must be proved beyond a reasonable doubt. A first refusal lasts until IID installation; a second carries one to two years following installation; a third or later carries eight years following installation, with additional IID periods under 39:4-50.17.

Drug-based DWI

Drug DWI can rest on observations, toxicology and a Drug Recognition Evaluator opinion. State v. Olenowski and the current Judiciary DRE charge limit the opinion to findings “consistent with” identified drug categories. DRE testimony alone is insufficient to prove drug DWI beyond a reasonable doubt; corroboration is required, the State generally must make a reasonable effort to obtain a toxicology sample, and the defense must have a fair opportunity to test the evaluator and the corroborating evidence. A first drug DWI carries seven months to one year of forfeiture and is excluded from IID-based waiver and credit provisions.

Mount Holly & Burlington County

Local office, evidence-first DWI defense

Shugar Law Office is based at 69 High Street in Mount Holly. Its current attorneys represent people charged with DWI and related municipal offenses in Burlington County and municipal courts throughout New Jersey.

Start with the stop

The defense begins with why the vehicle was stopped, what the officer observed and what the video and reports actually show. A lawful stop is the first link in the State's case.

Test the field evidence

Field-sobriety instructions, conditions, officer observations and recorded performance must be evaluated together. The report is not the end of that review.

Audit the Alcotest foundation

Discovery can include operator credentials, calibration and solution records, instrument documents, observation-period evidence and the individual test sequence. We test the foundation; we do not claim an unsupported certification.

If the charge arose locally, our Mount Holly Municipal Court guide explains the court's verified public information. The attorney roster identifies the lawyers currently associated with Shugar Law Office.

How We Fight DWI Cases

Match the evidence to the charged DWI theory

Discovery can show whether the State can prove operation, the alleged impairment or BAC theory, and the foundation required for the evidence it offers. A defect matters when the governing law makes it material; no rule requires a literally perfect investigation.

The stop itself

Police need reasonable suspicion to pull you over. If the stop was bad, the evidence that followed it can be suppressed, and without evidence there is no case.

Field sobriety tests

Roadside balance-and-walk tests are graded subjectively, often at night, on uneven shoulders, by officers looking for failure. Age, weight, injuries and footwear all undermine them.

The Alcotest foundation

Under State v. Chun, the State must produce foundational documents, including calibration, certification and maintenance records, before a breath reading comes into evidence. Missing or flawed paperwork can sink the reading.

The 20-minute observation

Before a breath test, police must continuously observe you for 20 minutes to rule out anything that could distort the result. Interruptions, even brief ones, can render the reading inadmissible.

Companion Charges

The DWI summons may not be the only statute in the case

N.J.S.A. 39:4-50.15 — minor passenger

This section creates an additional penalty when the State proves that the person convicted of DWI was the parent or guardian of a passenger who was 17 or younger. Passenger age alone is not enough: counsel must test both the parent-or-guardian relationship and the underlying DWI conviction rather than treating the allegation as another BAC tier.

N.J.S.A. 39:4-51a — consumption

This is the separate prohibition on consuming an alcoholic beverage or cannabis item while operating a motor vehicle. It is not interchangeable with proof of impairment under the DWI statute.

N.J.S.A. 39:4-51b — open container

This provision addresses an open or unsealed alcoholic-beverage container or cannabis item in the passenger compartment. Location, possession and the statutory exceptions must be reviewed independently from the DWI proofs.

What Else You Should Know

The fine print clients don't hear about until it's too late

Subsection (b) requires screening, evaluation, referral, program and fee compliance and a $100 Alcohol Education, Rehabilitation and Enforcement Fund fee; noncompliance can trigger the specified two-day jail term and continued licensing action. Subsection (f) governs IDRC classification, treatment referral, monitoring and per-diem fees. Subsection (i) adds a $125 court surcharge. These items are separate from the tier fine, other assessments, IID expense and any MVC surcharge. A municipal DWI appeal generally must be filed within 20 days under the court rules.

On plea agreements, the rules changed. For decades New Jersey flatly barred DWI plea bargaining. That ended in early 2024: the Legislature authorized plea agreements in DWI and refusal cases on the prosecutor's recommendation (P.L.2023, c.191), and the Supreme Court withdrew its long-standing guideline that had prohibited them. How much room a prosecutor has still varies case to case and court to court, which makes current, in-the-trenches municipal court experience worth more than ever. The volume is real, too: Mount Laurel Municipal Court alone logged 208 DWI filings in the July 2025–June 2026 court year (NJ Courts statistics), the most of any Burlington County municipal court.

A DWI stop also frequently produces companion tickets: reckless driving, lane violations, open container. We defend the whole event, not just the headline charge. See our traffic violations page for how those companion charges work.
