Leaving the scene of an accident in NJ is punished on a sliding scale under N.J.S.A. 39:4-129, running from a $200 fine for a minor property-damage hit-and-run up to $5,000 in fines, 180 days in jail, and a one-year license forfeiture when someone is injured or killed. A separate criminal statute can add three to five years in state prison if the victim suffered serious bodily injury. What you were driving, what you hit, and whether anyone was hurt all change which tier applies.
Penalties When Someone Is Injured or Killed
This is the harshest tier under the traffic code. A conviction under subsection (a) of 39:4-129 carries a fine between $2,500 and $5,000, up to 180 days in jail, and a one-year loss of your driver’s license on a first offense. A second or subsequent conviction brings permanent forfeiture of your New Jersey driving privileges.1Justia. New Jersey Code 39-4-129 – Action in Case of Accident
The $2,500 floor is one of the steepest minimum fines in the traffic code, and a judge has no authority to go below it. The jail term applies only when the injured or killed party was someone other than the convicted driver. Permanent means permanent: the statute writes in no reinstatement period and no hardship exception, so a second conviction effectively ends any career that requires driving.1Justia.

Separate Criminal Charges for Serious Bodily Injury
If the accident caused serious bodily injury, leaving the scene is also a third-degree crime under N.J.S.A. 2C:12-1.1. Third-degree crimes in New Jersey carry three to five years in state prison, and the usual presumption against prison for a first-time offender does not apply to this charge.2Justia. New Jersey Code 2C-12-1.1
Two features of this statute catch defendants off guard. The prosecution does not need to prove you knew the victim was seriously hurt; if the injury qualifies, the charge applies regardless of what you believed. And if you are also charged with aggravated assault or assault by auto, the leaving-the-scene conviction does not merge with those charges. Sentences are imposed separately and run consecutively.2Justia. New Jersey Code 2C-12-1.1
A driver who flees a serious crash can therefore face the traffic-code penalties under 39:4-129(a) and years of prison under the criminal code, stacked on top of each other.
Penalties When Only Property Was Damaged
When no one is hurt and the only harm is to vehicles or other property, subsection (b) sets a lower structure. A first offense carries a fine of $200 to $400, up to 30 days in jail, or both. A subsequent offense carries a fine of $400 to $600 and 30 to 90 days in jail, or both.1Justia. New Jersey Code 39-4-129 – Action in Case of Accident
The jump from first to second offense matters most on the jail side. A first offense can result in no jail time if the judge exercises discretion. A second offense carries a mandatory minimum of 30 days, which removes that discretion.1Justia. New Jersey Code 39-4-129 – Action in Case of Accident
The same rules reach unattended property. If you clip a parked car or knock down a mailbox and no one is around, you still have to stop and make a reasonable effort to find the owner. If you cannot, you must leave a written note in a conspicuous place on the damaged vehicle or property giving your name, address, and registration. Driving off instead exposes you to the same leaving-the-scene charges that apply when another driver is present.1Justia. New Jersey Code 39-4-129 – Action in Case of Accident
License Points, Surcharges, and Insurance
Court penalties are not the end of it. The Motor Vehicle Commission assesses 8 points for leaving the scene of an accident involving personal injury and 2 points when there is no injury. Eight points from a single violation is among the highest assessments on the MVC schedule.3NJ.gov. NJ Points Schedule
Once you have six or more points within a three-year period, the MVC imposes annual insurance surcharges: $100 for the first six points and $25 for each additional point, billed every year as long as you remain at or above six. An 8-point hit-and-run conviction triggers at least $150 per year in surcharges, before your private insurer reacts. Most carriers treat a leaving-the-scene conviction as a major violation, and premium increases of several hundred dollars a year are common.
What You Were Supposed to Do
Three duties attach the moment you know you have been in a collision, no matter who caused it. You must stop at the scene or as close to it as safely possible. You must give your name, home address, driver’s license, and vehicle registration to the other driver, any injured person, any occupants of the other vehicle, and any police officer or witness. And you must provide reasonable assistance to anyone who is hurt, which includes arranging transportation to a hospital or doctor when the need for care is obvious or the person asks for it.1Justia. New Jersey Code 39-4-129 – Action in Case of Accident
These duties apply whether the collision involves another vehicle, a pedestrian, or someone’s property, and whether the damage looks minor or the other party says they are fine.
The “Knowingly Involved” Standard
Every obligation under 39:4-129 hinges on one word: “knowingly.” The state does not have to prove you knew the full extent of the damage or that someone was hurt, only that you were aware you were in an accident at all. Once that awareness exists, the duties to stop, share information, and help the injured attach automatically.1Justia. New Jersey Code 39-4-129 – Action in Case of Accident
Subsection (e) makes “I didn’t realize” harder to argue. If the accident caused injury, death, or at least $250 in property damage, the statute allows a judge or jury to infer from the severity of the impact that you knew you were involved. The worse the damage, the weaker the claim that you felt nothing.4FindLaw. New Jersey Code 39-4-129 – Action in Case of Accident
A Separate Reporting Duty You Can Still Violate
Even if you stop and exchange information correctly, a different statute, N.J.S.A. 39:4-130, requires you to report any accident involving injury, death, or property damage over $500 to local police, county police, or the State Police by the quickest available means. You then have 10 days to file a written SR-1 accident report with the MVC.5Justia. New Jersey Code 39-4-130 – Immediate Notice of Accident
Drivers often assume that trading insurance cards at the scene takes care of everything. It doesn’t. The 10-day written report is a separate obligation, and skipping it is its own violation.6NJ.gov. SR-1 MVC Accident Report Form
