New Jersey's Open Container Law: Can a Passenger Be Cited Too?

What Counts as an "Open" Container Under NJ Law

New Jersey's open container statute, N.J.S.A. 39:4-51b, prohibits having an open, unsealed alcoholic beverage container in the passenger area of a motor vehicle on a public highway. "Open" is a broader concept than most people assume: it covers any container whose factory seal has been broken, including a recorked or resealed bottle, a can that's been popped open, and any cup or glass with an alcoholic beverage in it — even if it's a small amount, and even if no one is actively drinking from it at that moment.

The law applies to any beverage above 0.5% alcohol by volume that isn't in its original, sealed packaging. A full, unopened bottle stored in the trunk is a different situation entirely from the same bottle sitting open in a cupholder.

Penalties: First Offense vs. Second and Subsequent Offenses

The open container statute carries its own penalty structure, independent of any DWI charge:

• First offense — a $200 fine
• Second or subsequent offense — a $250 fine, or a court-ordered 10 days of community service

These penalties apply on their own, whether or not there's an accompanying DWI charge. An open container violation doesn't carry MVC driver violation points, which puts it in a similar category to DWI on that particular question — see our page on whether a DWI adds points to your license in New Jersey for how that separate point system works.

It's Not Just the Driver — Passenger Liability Explained

This is the part that catches people off guard: N.J.S.A. 39:4-51b applies to anyone in the vehicle, not just whoever is behind the wheel. A passenger holding an open beer or a half-finished cocktail can be cited directly, independent of what the driver is doing or whether the driver is impaired at all. "I wasn't driving" is not a defense to an open container citation the way it might feel like it should be.

In practice, this means a sober designated driver can still end up with passengers who receive citations, and a vehicle full of passengers can each be individually cited if each one has an open container. Officers generally have discretion in how broadly they enforce this during a given stop, but the statute itself doesn't limit liability to the driver. Vehicle ownership can carry its own separate exposure too — see our page on whether you can be held liable for letting someone drive drunk in your car in New Jersey if the person actually driving wasn't the vehicle's owner.

The Harsher Rule for Passengers Under 21

New Jersey treats open container violations involving people under 21 more seriously. A person under 21 found in possession of an open alcoholic beverage container in a vehicle can face a 6-month license suspension — a consequence tied to possession alone, regardless of whether that person was driving, drinking at that moment, or the one who brought the alcohol into the car in the first place. This is a separate consequence from New Jersey's zero-tolerance DWI law for drivers under 21; see our page on underage DWI in New Jersey for how that statute works when the person actually driving is under 21 and impaired.

How This Intersects With a DWI Investigation

An open container violation is a separate offense from DWI, and finding one doesn't by itself prove anyone was impaired. But it's exactly the kind of detail that ends up in a police report and can become part of a broader DWI case narrative — officers commonly note an open container as one factor supporting probable cause for further investigation, alongside things like the smell of alcohol, driving behavior, or field sobriety test results. It's corroborating context, not proof of impairment on its own.

This comes up often at DWI checkpoints in particular, where officers are specifically looking for signs of impairment in every vehicle that passes through and an open container in plain view is an easy thing to spot.

The Realistic Takeaway

Open container citations are often treated as an afterthought compared to a DWI charge, but they carry their own fines, their own harsher rule for minors, and their own role in building a larger DWI case. Anyone who receives one — driver or passenger — should understand it as a distinct legal matter, not just a footnote to whatever else happened during the stop.
