A DUI arrest in Jersey City usually starts a case in municipal court that can affect your license, your insurance, and your finances for years. New Jersey law calls the offense driving while intoxicated (DWI), and its penalties are tied closely to your blood alcohol reading. At The Law Offices of Anthony Carbone, we hear the same questions from almost everyone who calls after a DWI arrest. Will I lose my license? Is this a criminal record? What happens at court? The answers below reflect New Jersey’s current ignition interlock law.
Is a DUI a crime in New Jersey?
No. In New Jersey, DWI is a motor vehicle violation under N.J.S.A. 39:4-50, not a criminal offense. The case is heard in the municipal court where the arrest happened, which here is the Jersey City Municipal Court, and a judge decides it without a jury.
The penalties are still serious. A DWI conviction cannot be expunged and stays on your driving record. It is also not eligible for diversion programs like conditional dismissal.
What are the penalties for a first DUI in New Jersey?
For a first offense, the penalties depend on your blood alcohol concentration (BAC). An ignition interlock device, a breath-testing unit that keeps your car from starting if it detects alcohol, is now required in most first-offense cases.
| BAC | Fine | License | Ignition interlock |
| 0.08% to under 0.10% | $250 to $400 | Forfeited until interlock installed | 3 months |
| 0.10% to under 0.15% | $300 to $500 | Forfeited until interlock installed | 7 months to 1 year |
| 0.15% or higher | $300 to $500 | 4 to 6 months | During forfeiture, then 9 to 15 months |
Every first offender must also complete 12 to 48 hours at an Intoxicated Driver Resource Center (IDRC), an alcohol education and evaluation program. A judge can also impose up to 30 days in jail. A DWI based on drugs instead of alcohol carries a 7-month to 1-year license forfeiture in place of the interlock.
What happens with a second or third DUI?
Penalties increase sharply with each offense. A second offense carries a fine of $500 to $1,000, at least 48 hours in jail, 30 days of community service, and a license forfeiture of one to two years. A third offense carries 180 days in jail, up to 90 of which can be served in inpatient treatment, and an eight-year license forfeiture. If more than 10 years pass between offenses, the court sentences the newer offense as if it were one level lower.
What if you refused the breath test?
Refusing to give a breath sample at the station is a separate violation under N.J.S.A. 39:4-50.4a. For a first refusal, your license is forfeited until you install an interlock, the interlock must stay on for 9 to 15 months, and the fine is $300 to $500. You can be convicted of refusal even if the DWI charge itself fails.
What happens at court after a DUI arrest in Jersey City?
Most DWI cases begin with a summons and a first appearance date in the Jersey City Municipal Court. Your license is generally not suspended until a conviction. The months before trial are spent on discovery, which includes the Alcotest data, police video, and officer certifications.
Since February 2024, New Jersey has allowed some drivers to install an ignition interlock voluntarily after arrest, before any conviction. The time spent with the device can count toward the sentence and may shorten a later license forfeiture.
Can a DUI charge be beaten in New Jersey?
Yes, and many DWI cases have weak points. The stop must have been lawful, and the field sobriety tests must have been given and scored properly. The Alcotest, New Jersey’s breath-testing device, is reliable only when officers follow the procedures the New Jersey Supreme Court approved in State v. Chun (2008). Those procedures include watching the driver for 20 minutes before the test to make sure nothing could skew the result. When police skip a required step, the breath reading can be excluded, even if the rest of the case goes forward.
What does a DUI really cost in New Jersey?
The fine is often the smallest expense. A conviction also brings court surcharges, IDRC fees of $75 per day, the cost of renting an interlock device, and a Motor Vehicle Commission insurance surcharge of $1,000 a year for three years. Car insurance premiums also tend to rise. Driving while your license is forfeited for a DWI can lead to a fourth-degree criminal charge under N.J.S.A. 2C:40-26, which carries mandatory jail time.
