In 2025, New Jersey amended the DWI (Driving While Intoxicated) penalties under N.J.S.A. 39:4-50, with specific updates regarding ignition interlock devices (IID)and sentencing credits that went into effect in early 2024 and 2025. Penalties are primarily determined by the driver's Blood Alcohol Concentration (BAC) and their history of prior offenses.
First-Offense DWI Penalties
Penalties for a first offense depend on the BAC level at the time of arrest:
· BAC 0.08% to 0.10%
o License Suspension: Forfeiture until an IID is installed; the IID must then remain for 3 months.
o Fines: $250–$400.
o Other: 12–48 hours at an Intoxicated Driver Resource Center (IDRC) and a $1,000 annual insurance surcharge for 3 years.
· BAC 0.10% to 0.15%
o License Suspension: Forfeiture until an IID is installed; the IID must then remain for 7–12 months.
o Fines: $300–$500.
o Other: 12–48 hours at IDRC and a $1,000 annual insurance surcharge for 3 years.
· BAC 0.15% or Higher
o License Suspension: Mandatory 4–6 months.
o IID Requirement: Must use an IID during the suspension and for 9–15 months after restoration.
o Fines: $300–$500.
Repeat Offense Penalties
For offenses occurring within 10 years of a prior conviction:
· Second Offense
o License Suspension: 1–2 years.
o Jail Time: Mandatory 48 hours to 90 days.
o IID Requirement: During suspension and for 2–4 years after restoration.
o Fines & Fees: $500–$1,000 fine and 30 days of community service.
· Third or Subsequent Offense
o License Suspension: 8 years (amended from 10 years in recent 2025 legislation).
o Jail Time: Mandatory 180 days; up to 90 days may be served in an approved inpatient rehabilitation program.
o Fines: $1,000.
o IID Requirement: During suspension and for 2–4 years after restoration.
2025 Key Updates & Credits
· "2-for-1" IID Credit: As of April 2025, certain drivers may earn one day off their license suspension for every two days they have a compliant IID installed before their court date.
· Plea Bargaining: Historically prohibited, a 2024 law now allows prosecutors some discretion to offer plea deals in DWI cases under specific conditions, though judicial approval is required.
· 10-Year Step-Down: If 10 years have passed since your last DWI, the court may sentence a subsequent offense as if it were one tier lower (e.g., a second offense treated as a first).
Additional Mandatory Surcharges (All Offenses)
Beyond fines, every conviction includes:
· Insurance Surcharge: $1,000 to $1,500 per year for 3 years.
· Surcharges: $125 DWI surcharge, $100 Drunk Driving Enforcement Fund, and $75 Safe Neighborhood Services Fund.
