New Jersey DWI penalties breakdown: every component, line by line
Our New Jersey DUI costs page gives the state overview. This page does the narrower job: New Jersey prices a first DWI by exact concentration tier under N.J.S.A. 39:4-50, and its heaviest state charge is not the fine at all — so this page prices the fine, the four statutory fees, the Motor Vehicle Commission surcharge, the IDRC requirement and the interlock periods separately, with no added-up total.
The first-offence tiers: the fine moves less than the interlock term
Since the 2019 reform of § 39:4-50, a first DWI is built around the interlock rather than a long license forfeiture. At a concentration of 0.08 to under 0.10, the fine is $250 to $400, the court may impose up to 30 days in jail, and the driver must install an interlock for three months, with no additional period of license forfeiture once the device is installed. At 0.10 to under 0.15, the fine rises to $300 to $500, the same discretionary jail exposure applies, and the interlock term runs from seven months to one year. At 0.15 or higher, the fine remains $300 to $500, but the license is forfeited for four to six months and the interlock must remain during the forfeiture and for nine to fifteen months after restoration. Every first offender must also satisfy the Intoxicated Driver Resource Center requirement — 12 to 48 hours of attendance and evaluation at the county IDRC, with treatment referral where the evaluation requires it — and the IDRC charges its attendance fee under the programme's own schedule.
Four statutory charges attach to the fine in every case and are worth pricing individually, because together they approach the size of the fine itself: a $100 Drunk Driving Enforcement Fund assessment, a $50 Violent Crimes Compensation Board assessment, a $75 Safe Neighborhood Services Fund assessment, and a $100 assessment under § 39:4-50(i) — $325 in statutory fees on top of the fine, before court costs. A second conviction within ten years carries a fine of $500 to $1,000, imprisonment of 48 consecutive hours to 90 days, 30 days of community service, forfeiture of one to two years, and interlock during the forfeiture and for two to four years after restoration. A third conviction within ten years carries a $1,000 fine, 180 days of imprisonment — up to 90 of which may be served in an approved inpatient programme — and an eight-year forfeiture.
The MVC surcharge: a state charge of $1,000 a year for three years
The largest single state charge in a New Jersey DWI is the Motor Vehicle Commission surcharge: $1,000 a year for three years — $3,000 in all — assessed by the MVC under its surcharge schedule on a DWI conviction, and assessed again on a repeat conviction. It is a state surcharge billed by the MVC, not an insurance premium, and it is listed here for exactly that reason: it is published, it is fixed, and unpaid surcharges suspend driving privileges in their own right. A refusal conviction under § 39:4-50a carries the same surcharge structure alongside its own fine of $300 to $500 on a first offence, an IDRC requirement, and an interlock term of nine to fifteen months, with the license suspended until the device is installed.
What New Jersey does not fix by statute is the rest of the stack: municipal court costs vary by court, the IDRC attendance fee is charged under the programme's schedule, and interlock installation and leasing are billed by the MVC-approved vendor. Those are real costs of every New Jersey case, and they are identified here as requirements and local charges rather than folded into the statutory table. Our interlock page, refusal page and programmes page cover those layers.
| DUI component | Published amount |
|---|---|
| First offence — 0.08 to under 0.10 (§ 39:4-50) | Fine $250–$400; up to 30 days discretionary; interlock 3 months; no added forfeiture once installed |
| First offence — 0.10 to under 0.15 (§ 39:4-50) | Fine $300–$500; up to 30 days discretionary; interlock 7 months–1 year |
| First offence — 0.15 or higher (§ 39:4-50) | Fine $300–$500; forfeiture 4–6 months; interlock during forfeiture plus 9–15 months after restoration |
| Statutory fees on a DWI (§ 39:4-50) | $100 Drunk Driving Enforcement Fund + $50 Violent Crimes Compensation + $75 Safe Neighborhood Services Fund + $100 under § 39:4-50(i) = $325, plus court costs |
| MVC surcharge (NJ MVC surcharge schedule) | $1,000 per year for 3 years ($3,000) — a state surcharge billed by the MVC, not an insurance charge |
| IDRC requirement (§ 39:4-50) | 12–48 hours at the county Intoxicated Driver Resource Center on a first offence; attendance fee charged under the programme schedule |
| Second conviction within 10 years | Fine $500–$1,000; 48 consecutive hours–90 days; 30 days community service; forfeiture 1–2 years; interlock during and 2–4 years after |
| Third conviction within 10 years | Fine $1,000; 180 days (up to 90 in approved inpatient treatment); forfeiture 8 years |

Open the DUI cost calculatorWhat this state does not publish as a single figure
The MVC surcharge is the figure most often misreported in New Jersey DWI cost pages — either omitted because it is not part of the court sentence, or confused with an insurance increase. It is neither: it is a fixed state surcharge of $1,000 a year for three years, billed by the Motor Vehicle Commission, and it appears in the table as exactly that. What a New Jersey DWI does to the price of insuring a car is a separate, insurer-set figure that no state source publishes and this site does not estimate.
Municipal court costs, the IDRC attendance fee and interlock vendor charges also sit outside § 39:4-50's numbers. New Jersey DWI is a traffic offence rather than a criminal conviction, which affects how the record is described, but it does not reduce any of the charges priced here.
Common questions
- Why is the fine smaller than the surcharge?
- Because New Jersey splits the money: the municipal court fine on a first offence is $250–$500 by tier, while the MVC bills its own $1,000-a-year surcharge for three years — $3,000, more than any first-offence fine.
- Does a first offender at 0.08 lose the license?
- Under the current § 39:4-50, a first offender in the lowest tier faces no additional forfeiture once the interlock is installed; the device term is three months. At 0.15 or higher, a four-to-six-month forfeiture applies.
- What are the $325 of statutory fees?
- $100 to the Drunk Driving Enforcement Fund, $50 to the Violent Crimes Compensation Board, $75 to the Safe Neighborhood Services Fund and $100 under § 39:4-50(i) — charged on top of the fine in every DWI case.
