Can You Use Someone Else’s E-ZPass in NJ? Rules, Fees, and Rentals

You can use someone else’s E-ZPass in NJ only if your vehicle is already listed on their account and your vehicle’s class matches the tag. Drive through a toll plaza in a car that isn’t on the account, or in a vehicle heavier or with more axles than the tag was issued for, and the system treats the trip as a violation. The account holder owes every toll and fee the tag generates, so lending a transponder is a bigger commitment than it looks.¹

When Sharing a Tag Is Actually Allowed

The transponder belongs to the issuing agency, not to the account holder. The agreement authorizes use only on vehicles listed on the account, and only when the tag type matches the vehicle class. A Class 1 tag covers motorcycles and two-axle passenger vehicles. It cannot ride in a commercial truck or anything with more axles than the tag was issued for.¹

So the practical rule is simple. If a friend’s car is already on your account, and their car fits the tag’s class, handing them the transponder processes like any other trip. If their car isn’t on your account, the cameras photograph a plate that doesn’t match the tag, and enforcement kicks in. There is no grace period for “I was just borrowing it.”

NJ E-ZPass asks for the make, model, year, and plate number of every vehicle that will use the tag. The high-speed camera system (V-Toll) reads the plate when the transponder doesn’t register properly. A matching plate on the account bills the right account automatically. No match, and the passage is flagged as a violation.¹

Who Pays When the Tag Gets Used in the Wrong Car

By opening the account, the holder agrees to pay every charge the tag generates, including charges from facilities in other states that accept E-ZPass. The agreement does not distinguish between the account holder driving and someone else driving. The account gets debited, and charges are non-refundable. Unpaid charges can bring additional penalties under law, and the account itself can be suspended or revoked.¹

Enforcement doesn’t stop with the account holder. When a vehicle passes without a valid transponder read, or with a plate that doesn’t match any account, the New Jersey Turnpike Authority can send an advisory and payment request to the registered owner of the vehicle within 60 days. That notice goes to whoever owns the car in the camera photo, not necessarily the person whose tag was in the dashboard. A friend who borrowed your tag can get a notice at their home while your account also catches charges on its end.²

The administrative fee is $50 per violation, on top of the unpaid toll. If the owner can prove the violation was truly inadvertent, the $50 fee may be waived and only the toll remains due. “Inadvertent” is narrow. Forgetting to bring the transponder, entering an E-ZPass lane without a working tag, or not having enough coins in a basket lane do not qualify.³⁴

Ignore the advisory for more than 30 days and the owner becomes liable for a formal summons and complaint. A court then handles the matter and can impose civil penalties on top of the toll and the administrative fee. Several $50 violations from a single week of lending the tag add up quickly.²

Using Your Own E-ZPass in a Rental Car

Rentals are where this question comes up most often. NJ E-ZPass lets you add a rental car’s plate to your account. Log in, open the Tags/Vehicles menu, select Vehicle List, and enter the rental’s plate, make, model, and year. The system needs up to 24 hours for changes to propagate through the tolling network, so add the plate at least the night before you drive.

Skip that step and mount the tag anyway, and the cameras photograph a plate that doesn’t match your account. The notice goes to the rental company, which passes the cost to you along with its own surcharge. Return the car and remove that plate from your account the same day. Any plate still sitting on your account is a plate that can bill tolls to you.

Discount Tags That Cannot Be Shared

Several NJ E-ZPass discount programs lock a tag to a specific driver or vehicle. Lending one of these tags doesn’t just forfeit the discount; a vehicle-class mismatch can turn the passage into a violation.⁵

The Senior Citizen Discount gives 10 percent off the off-peak rate on the Turnpike and Garden State Parkway for drivers 65 and older, and the eligible senior must be in the car when the toll is charged.
The Green Pass Discount gives 10 percent off the off-peak rate for vehicles rated at 45 miles per gallon or better that meet California Super Ultra Low Emission Vehicle standards, tied to a specific registered vehicle.
The Garden State Parkway Trailer Discount applies to Class 2 through 5 vehicles that qualify for Class 1 pricing due to configuration, is tag-specific, and is not available to business or commercial accounts.

How to Add a Vehicle Before Someone Else Drives With Your Tag

If you want to let another person use your transponder legitimately, their vehicle has to be on your account before they reach a toll gantry. Adding it afterward won’t undo a violation that already triggered.¹

Online: log in at EZPassNJ.com, open Tags/Vehicles, select Vehicle List, and enter the plate, make, model, and year.
Phone: call 1-888-AUTO-TOLL (1-888-288-6865) with the vehicle details ready.
Mobile app: the NJ E-ZPass app offers the same vehicle management under your account profile.

Allow up to 24 hours for the change to activate across the tolling network. Confirm the vehicle shows as active before the trip. When the other driver no longer needs the tag, remove their vehicle right away. And remember your prepaid balance has to cover the added activity: NJ E-ZPass can adjust auto-replenishment based on how much the account processes, so a second regular driver on your tag can push your automatic charges up noticeably.

If the Tag Is Lost or Stolen Rather Than Lent

Unauthorized use is a different situation from sharing. You will not be charged for tolls incurred after you report the tag lost or stolen, but every toll before that report posts to your account. Report a lost or stolen transponder through the NJ E-ZPass website or by calling 1-888-AUTO-TOLL (1-888-288-6865); the automated phone system takes reports at any hour. Don’t dispute the charges with your bank first. Chargebacks on toll charges can create problems with your account status, so let the agency investigate and credit any unauthorized use through its own resolution process.⁶
