The NJ Leaving-the-Scene Statute
N.J.S.A. 39:4-129, explained.
"Hit and run" covers everything from an unnoticed parking-lot tap to a felony-level injury case, and New Jersey's penalties range just as widely — up to permanent loss of your license. Which tier you're in, and what the state must prove, decide everything.
What the Statute Requires
Your duties at an accident scene
The statute requires a driver knowingly involved in an accident to stop immediately (or as close to the scene as possible), remain there, provide identifying information, and render reasonable aid where anyone is injured. The word doing the heavy lifting is knowingly — the state has to prove you were aware an accident happened. That element is where many defenses live, especially in low-speed, minor-contact cases.
The Two Tiers
Penalties by tier
| Consequence | Property damage (attended) | Injury or death |
|---|---|---|
| Fine | $200–$400 (1st) · $400–$600 (2nd+) | $2,500–$5,000 |
| Jail | Up to 30 days (1st) · 30–90 days (2nd+) | 180 days (required where another person was hurt or killed) |
| License forfeiture | 6 months (1st) · 1 year (2nd+) | 1 year (1st) · permanent (2nd+) |
| MVC points | 2 | 8 |
| Criminal exposure | — | Third-degree crime under 2C:12-1.1 where serious bodily injury results — Superior Court, and the usual presumption against imprisonment for first-time offenders does not apply |
Even the "minor" tier costs a license for six months — a penalty far heavier than the underlying fender-bender would ever have drawn. Which is the point worth absorbing: the accident itself is almost never the serious legal problem. Leaving is.
The Fight
Where these cases get defended
Knowledge
The state must prove you knew an accident occurred. Glancing contact, noise, weather, vehicle size — plenty of real collisions genuinely go unnoticed, and the state's proof of awareness is often assumption.
Identity
Most cases start from a reported plate, not a stopped driver. A plate identifies a car; the state must still prove who was behind the wheel — and statements volunteered to investigators are usually how they do it.
Compliance
Did an exchange of information happen? Did the other party leave first? Was the stop made as close to the scene as safely possible? The statute's duties have edges, and the facts often sit closer to compliance than the ticket suggests.
Every case is different and no outcome is guaranteed. But leaving-the-scene charges are fact-heavy, element-driven cases — precisely the kind where early representation changes what's possible.
Common Questions
39:4-129 questions we hear
I tapped a parked car and panicked. How bad is this?
An attended-property-damage case under 39:4-129(b) carries a $200–$400 fine, up to 30 days of jail exposure, 2 points, and — the part that surprises everyone — a six-month license forfeiture on a first offense. It is serious, but it is the most defensible tier: the state must prove you knew there was an accident, and low-speed contact you genuinely did not notice is a real and recognized defense.
What if someone was hurt?
Leaving the scene of an injury accident is a different universe: a $2,500–$5,000 fine, 180 days in jail where someone other than you was hurt or killed, 8 points, a one-year license forfeiture (permanent for a repeat), and separate exposure to a third-degree criminal charge under 2C:12-1.1 when the injury is serious. Anyone in this position needs a lawyer before speaking to police.
The police contacted me days after an accident. What do I do?
Do not give a statement before talking to a lawyer. These cases are usually built on a plate reported by a witness — the state still has to prove who was driving and that the driver knew an accident had happened. Well-meaning explanations to a detective routinely supply the only proof of both. Call counsel first; it is not evasive, it is how the system is designed to work.
Does my duty at the scene ever end?
Your obligations under the statute are to stop, remain, give your identifying information, and render reasonable aid where someone is hurt. Once those duties are met you may leave. Disputes often turn on whether information was exchanged or whether the other party left first — facts worth documenting at the time if you can.
