DUI Laws in New Jersey (DWI)
New Jersey uses the term "DWI" for impaired driving offenses. The standard BAC limit is 0.08%. The lookback period is 10-year step-down. DWI itself is never classified as a felony or indictable offense in New Jersey — it remains a traffic violation regardless of number of offenses. However. Below are the full details of New Jersey's DUI laws and penalties.

Overview
New Jersey classifies impaired driving as DWI (Driving While Intoxicated) and uniquely handles it as a traffic offense rather than a criminal offense — meaning a DWI conviction does not result in a criminal record in the traditional sense. However, penalties are severe and include mandatory license suspension, ignition interlock requirements, and substantial fines and surcharges. New Jersey has no lookback period limitation; all prior DWI convictions count toward enhancement regardless of age. The state's Intoxicated Driver Resource Center (IDRC) program is mandatory for all DWI offenders. New Jersey law was significantly reformed in 2019 (known as 'DWI Reform'), reducing license suspension periods in favor of mandatory IID installation.
Official term: DWI
BAC Limits
| Driver Type | BAC Limit |
|---|---|
| Standard (21+) | 0.08% |
| Commercial (CDL) | 0.04% |
| Under 21 | 0.01% |
| Enhanced Penalty | 0.10% — triggers higher-tier first offense penalties; 0.15% triggers enhanced penalties across all offense levels |
Penalties by Offense
| Offense | Classification | Jail Time | Fines | License Suspension | IID |
|---|---|---|---|---|---|
| 1st Offense | Traffic violation (not a criminal charge). Two tiers: BAC 0.08–0.099% and BAC 0.10%+ | Up to 30 days. No mandatory minimum for BAC 0.08–0.099%. Possible 12–48 hours at IDRC for all first offenders. | BAC 0.08–0.099%: $250–$400. BAC 0.10%+: $300–$500. Plus mandatory surcharges of $1,000/year for 3 years ($3,000 total), IDRC fee ($230 first offender; $280 second offender), $100 drunk driving fund, $100 AERF, $125 court surcharge (39:4-50(i)), $75 Neighborhood Services Fund surcharge. | BAC 0.08–0.099% and BAC 0.10–0.149%: no fixed suspension — the license is forfeited only until an IID is installed (N.J.S.A. 39:4-50(a)(1)(i)-(ii)). BAC 0.15%+: a 3-month suspension that begins once the IID is installed (39:4-50(a)(1)(ii)); drug-DWI first offenders face a 7-month to 1-year suspension with no IID substitution | Mandatory. BAC 0.08–0.099%: 3 months. BAC 0.10–0.149%: 7–12 months. BAC 0.15%+: 12–15 months after restoration (N.J.S.A. 39:4-50.17(a)(2); the 9–15-month range applies to a first breath-test refusal). Voluntarily installing an IID before conviction earns a 1-day credit against any suspension for every 2 days installed |
| 2nd Offense | Traffic violation | Mandatory minimum 2 days; up to 90 days. 30 days mandatory community service possible. | $500–$1,000 plus $1,000/year surcharge for 3 years ($3,000), IDRC fees, and other mandatory assessments. Total financial impact typically $5,000–$10,000+. | 1–2 years license suspension (applies when the prior offense is within 10 years; a second offense more than 10 years after the first is sentenced as a first offense — N.J.S.A. 39:4-50(a)) | Mandatory IID for 2–4 years after license restoration |
| 3rd Offense | Traffic violation (still not criminal, but penalties approach felony-level severity) | Mandatory minimum 180 days; court may order up to 180 days in an inpatient rehabilitation program in lieu of 90 of the 180 days | $1,000 plus $1,500/year surcharge for 3 years ($4,500), IDRC fees, and other assessments. Total financial impact typically $10,000–$15,000+. | 8-year license suspension | Mandatory IID for 2–4 years after license restoration |
| Felony | Not applicable for DWI charges. Vehicular homicide while intoxicated: 2nd-degree crime (indictable offense) | Vehicular homicide while intoxicated: 5–10 years in state prison; mandatory minimum under No Early Release Act (NERA) — must serve 85% of sentence | Up to $150,000 for vehicular homicide | Vehicular homicide: license revocation by MVC; period determined by court | Required after any license restoration following vehicular homicide conviction |
Felony threshold: DWI itself is never classified as a felony or indictable offense in New Jersey — it remains a traffic violation regardless of number of offenses. However, vehicular homicide while intoxicated is a 2nd-degree crime (equivalent to a felony).. Lookback period: 10-year step-down — a second offense occurring more than 10 years after the first is sentenced as a first offense, and a third occurring more than 10 years after the second is sentenced as a second offense (N.J.S.A. 39:4-50(a)).
Additional Penalty Details
| Offense | Community Service | Probation | DUI School |
|---|---|---|---|
| 1st Offense | Court may order up to 30 days community service | No formal probation for traffic offenses, but IDRC compliance is mandatory and monitored | Mandatory 12–48 hour detention and education at an Intoxicated Driver Resource Center (IDRC). Clinical assessment and referral to treatment as needed. |
| 2nd Offense | 30 days mandatory community service | IDRC compliance; potential court-ordered treatment program for up to 2 years | Mandatory 48 hours at IDRC; intensive outpatient treatment often required |
| 3rd Offense | At court's discretion | IDRC compliance; intensive treatment and monitoring for extended period | Mandatory IDRC program; court-ordered inpatient or intensive outpatient treatment |
| Felony | At court's discretion | Parole supervision after prison; extended treatment requirements | Mandatory treatment as condition of parole/supervision |
Implied Consent Law
Under New Jersey's implied consent law (N.J.S.A. 39:4-50.2), any person who operates a motor vehicle on New Jersey roads is deemed to have given consent to the taking of breath samples for testing. Note: New Jersey's implied consent statute specifically references breath testing; blood tests generally require consent or a warrant, except in exigent circumstances.
Refusal penalties: First refusal: $300–$500 fine, license forfeited until an IID is installed, then IID for 9–15 months (N.J.S.A. 39:4-50.4a; 39:4-50.17(a)(2)). Second refusal: $500–$1,000 fine, 1–2 years suspension, then IID for 2–4 years. Third or subsequent refusal: $1,000 fine, 8-year suspension, then IID for 2–4 years. The $1,000/year MVC surcharge applies to refusal as well. Refusal penalties run concurrently or consecutively with any DWI conviction, depending on the court. A refusal charge is separate from and in addition to the DWI charge itself.
Aggravating Factors
| Factor | Impact |
|---|---|
| BAC of 0.10% or higher (first offense tier increase) | Higher fine range ($300–$500 vs $250–$400), longer mandatory IID period (7–12 months vs 3 months) |
| BAC of 0.15% or higher | Adds a 3-month suspension (starting after IID installation) plus the longest IID period, 12–15 months, on a first offense (39:4-50(a)(1)(ii); 39:4-50.17(a)(2)) |
| DWI in a school zone | Mandatory doubling of all penalties: fines, license suspension, community service, and jail time (N.J.S.A. 39:4-50(g)) |
| Minor passenger under age 18 | Additional disorderly persons offense (equivalent to misdemeanor) carrying up to 6 months additional jail; separate license suspension |
| DWI causing serious bodily injury | 3rd-degree assault by auto charge (indictable crime): 3–5 years imprisonment; 4th-degree if injury is non-serious |
| DWI causing death | Vehicular homicide: 2nd-degree crime with 5–10 years imprisonment and mandatory 85% time served under NERA |
DUI with Injury
Classification: 3rd-degree crime — Assault by auto while intoxicated (N.J.S.A. 2C:12-1(c)); 2nd-degree crime — Vehicular homicide (N.J.S.A. 2C:11-5)
Assault by auto (serious bodily injury while DWI): 3rd-degree crime with 3–5 years in state prison and up to $15,000 in fines. Vehicular homicide while DWI: 2nd-degree crime with 5–10 years in state prison, up to $150,000 in fines, and mandatory 85% minimum time served under NERA. DWI-caused death without proven recklessness can also be charged as strict liability vehicular homicide, a 3rd-degree crime (N.J.S.A. 2C:11-5.3). In a school zone, vehicular homicide while DWI is a 1st-degree crime carrying 10–20 years. Restitution mandatory.
Underage DUI
Drivers under 21 with BAC of 0.01% or higher face a 30–90 day license suspension for a first offense and a longer suspension for subsequent offenses. Mandatory 15–30 days community service and participation in an alcohol education and highway safety program (IDRC). If BAC is 0.08% or higher, the underage driver faces the same full adult DWI penalties. Parents/guardians are notified for minors under 18.
Diversion Programs
New Jersey does not currently offer a formal DUI diversion program. New Jersey does not permit pretrial intervention (PTI) or conditional dismissal for DWI offenses. Unlike most other traffic violations and criminal offenses, DWI is specifically excluded from diversion programs by statute (N.J.S.A. 39:4-50). A DWI charge cannot be plea-bargained to a lesser charge in municipal court. However, the mandatory IDRC program and court-ordered treatment function as rehabilitative components of sentencing.
How Long a DUI Stays on Your Record
A DWI conviction permanently remains on your New Jersey driving abstract (driving record) maintained by the MVC. Because DWI is a traffic offense in New Jersey rather than a criminal charge, it does not appear on a traditional criminal background check. However, it remains on your driving record permanently and is always accessible to courts, law enforcement, and insurance companies. There is no expungement for DWI in New Jersey because it is not a criminal conviction — the expungement statute applies only to criminal records.
