Understanding DWI Penalties in New Jersey
Updated on 09/11/2025
A DWI arrest in New Jersey can feel overwhelming. People often wonder, ‘Will I lose my license?’ Will I go to jail? How much will this cost me?
The truth is that New Jersey has some of the harshest DWI penalties in the country. Convictions result in mandatory fines, surcharges, license suspension, and, in some cases, imprisonment. Repeat offenders face escalating punishments, regardless of whether their Blood Alcohol Content (BAC) was high or low at the time of arrest.
This guide explains the penalties for first, second, and third DWI offenses, the real financial impact, aggravating circumstances that increase penalties, and how an attorney can help.
First, Second, and Third Offense DWI Penalties in NJ
First Offense
- BAC 0.08% to under 0.10%: Up to 30 days in jail, 3-month license forfeiture, $250–$400 fine, 12–48 hrs IDRC, 3 months ignition interlock after suspension.
- BAC 0.10% to under 0.15%: Up to 30 days in jail, 7–12 months license forfeiture, $300–$500 fine, 12–48 hrs IDRC, 7–12 months ignition interlock.

Ignition Interlock Requirements and BAC Testing in NJ
Ignition interlock devices (IIDs) are tied directly to BAC levels and repeat offenses:
- Required for all first-time offenders with a BAC of 0.15% or higher.
- Needed for 7–12 months for BAC 0.10%–0.15%.
- Lower BAC levels may be ordered at the judge’s discretion.
- Mandatory for all second and third offenses for 1–3 years after suspension.
Recent Update: In some cases, voluntary early installation of an IID may reduce post-suspension requirements. Consult with an attorney to determine if this applies to your specific case.
The Real Cost of a DWI in New Jersey (Fines, Fees & Surcharges)
The financial impact of a DWI goes far beyond fines. When you add surcharges, fees, and hidden expenses, the actual cost can exceed $10,000 for a first offense and $ 35,000 or more for repeat offenders.
Breakdown of typical costs:
- Court fines: $250–$1,000 (depending on offense).
- The insurance surcharge is $1,000/year for 3 years ($3,000 minimum).
- IDRC program fees.
- Ignition interlock installation and monthly fees.
- Tow and impound fees.
- Possible attorney fees.

The Consequences of a DWI in New Jersey: Employment, CDL & Immigration
Beyond fines and license loss, a DWI conviction can affect nearly every part of your life:
- Employment: Lost job opportunities, particularly for roles requiring driving.
- Commercial Drivers (CDL): CDL holders face a 0.04% BAC threshold. A DWI can suspend personal and commercial licenses, often ending a driving career.
- Under-21 Drivers: Any BAC of 0.01%+ results in penalties including license suspension, fines, IDRC, and possible community service.
- Professional Licenses: Teachers, nurses, lawyers, and others may face disciplinary action.
- Immigration Status: Non-citizens may encounter visa, green card, or citizenship complications.
- Travel: Some countries restrict entry after DWI convictions.
- Insurance: Premiums rise significantly, or policies may be dropped.
Aggravating Factors in NJ DWI Penalties: High BAC, Minors & Refusal to Submit
Not all DWIs are treated equally. Penalties rise if:
- Your BAC was very high (0.15% or higher).
- A minor passenger was in the vehicle.
- You were involved in an accident-causing injury.
- You refused to submit to a DWI breath test.
Review our guide on DWI testing in New Jersey.
Note: New Jersey’s school zone DWI law was repealed in 2019. However, judges may still consider the presence of children or the location of the offense as aggravating factors when deciding penalties.
Some cases may even lead to criminal charges such as Assault by Auto or Vehicular Homicide.
Additional Penalties for Refusal to Submit in NJ
Refusal penalties are separate from DWI penalties. That means you can be punished for both refusal and the underlying DWI.

- First Refusal: $300–$500 fine + $1,000/year (3 years) insurance surcharge, 7–12-month license suspension, 6–12 months ignition interlock, IDRC required.
- Second Refusal: $500–$1,000 fine + $1,000/year (3 years) insurance surcharge, 2-year license suspension, 1–3 years ignition interlock, IDRC required.
- Third Refusal: $1,000 fine + $1,000/year (3 years) insurance surcharge, 10-year license suspension, 1–3 years ignition interlock, IDRC required.
