You check your E-ZPass statement and something is clearly wrong. A toll you never drove, a charge twice what it should be, or a violation notice that appeared out of nowhere. You are not alone. With billions of transactions processed every year across 19 member agencies in 17 states, billing errors are more common than most people realize.
The good news is that most errors can be fixed. This guide covers everything you need to know, from why errors happen to exactly how to dispute them, state by state.

Quick Answer: What Should You Do Right Now?
If you spot a billing error, take these steps immediately:
- Screenshot the incorrect charge in your transaction history
- Note the transaction ID, date, amount, and plaza name
- Contact your issuing agency (the state that gave you your transponder)
- File your dispute before the deadline passes
Deadlines vary by state. New York gives you 180 days. New Jersey allows 120 days. Pennsylvania enforces a strict 45-day window. Do not wait.
Why E-ZPass Billing Errors Happen
Understanding why errors occur makes them much easier to fix. E-ZPass relies on two technologies working together: Radio Frequency Identification (RFID) from your transponder, and Automatic License Plate Recognition (ALPR) from overhead cameras.
When RFID fails, the system falls back to plate recognition. That backup system is less accurate and often charges a higher rate.
Transponder Read Failures
Your transponder sends a signal on a 915 MHz frequency. Several things can block that signal:
- Metallic windshield coatings (solar tinting, heating elements, night vision glass)
- Incorrect mounting position
- Holding the tag by hand instead of mounting it
- An aging transponder with a weak battery
The Pennsylvania Turnpike reports that improper transponder mounting is the single leading cause of Video Tolls (V-Tolls). A properly mounted tag reads correctly 99.5% of the time. The fix is simple: place your tag at least one inch below the roofline and one inch to the right of your rearview mirror support, per the DriveEzMD mounting guide.
License Plate Misreads
Even when cameras work perfectly, they can still misread plates. Common reasons include:
| Cause | Effect | Example |
|---|---|---|
| Rain or fog | Blurred image, wrong character read | “B” read as “8” |
| Dirt or mud on plate | Partial characters, wrong number | “0” read as “D” |
| Bike rack or trailer | Camera view blocked entirely | No read, video toll issued |
| New plate font styles | OCR software confused by unfamiliar characters | See PA case below |
The 2026 Pennsylvania License Plate Crisis
Pennsylvania introduced new “Let Freedom Ring” plates for the U.S. 250th anniversary. The redesigned plates included a slash through the zero to help cameras tell “0” from “O.”
It backfired. The ALPR software used by the Pennsylvania Turnpike Commission frequently misread the slashed zero as the number “8.” Thousands of drivers received toll bills for vehicles they had never driven.
The Turnpike needed a period of software recalibration before the system could reliably read the new characters. CBS News Pittsburgh reported on the widespread billing confusion this caused.
The Most Common Types of Billing Errors
Knowing what to look for makes catching errors much faster.
Individual Account Errors
- Duplicate toll charge. The same plaza appears twice within seconds.
- Cash rate applied instead of E-ZPass rate. The system missed your transponder and billed the higher video toll rate.
- Toll from another vehicle. A plate misread linked someone else’s trip to your account.
- Violation notice for a toll already paid. The system failed to match your transponder read to your account payment.
- Auto-replenishment triggered incorrectly. Your balance was fine, but the system pulled extra funds anyway.
How Small Errors Become Big Bills
This is where things get serious. A missed $2 toll can legally escalate into a $52 bill once administrative fees are added. In New Jersey, those fees can multiply a minor error roughly 25 times over.
Here is a summary of current agency fees:
| Agency | Monthly Service Fee | Administrative Penalty |
|---|---|---|
| New York (MTA/PANYNJ) | $1.00 | Up to $50.00 per occurrence |
| New Jersey (NJTA) | $1.00 | Up to $50.00 per occurrence |
| Virginia (VDOT) | None | $20.00 lost/stolen fee |
| Pennsylvania (PTC) | None | Varies by violation stage |

The “snowball effect” is real. An expired credit card leads to a failed replenishment. A failed replenishment drains your balance. A drained balance triggers an invalid tag message. Each invalid tag message can cost up to $50. That is how a $3 toll turns into a $300 problem.
How to Dispute an E-ZPass Billing Error
Every state runs its own dispute process. Here is a state-by-state breakdown of what you need to know.
New York
New York offers one of the longest dispute windows in the network. Key facts:
- Deadline: 180 days from the date of the toll or fee
- Dispute method: Written submission to the Customer Account Correspondence office in Albany
- For violation notices: Complete Section C on the back of the notice and return it to the Violation Payments and Inquiries office
- Registration suspension: Contact E-ZPass at 1-800-333-TOLL to resolve the debt before the NY DMV will reinstate your registration
The NY DMV explains that three or more violations in a set period can result in a suspended registration. The DMV does not handle disputes directly. You must clear the toll debt first through E-ZPass, then contact the DMV.
For billing questions, the MTA toll payment page and the E-ZPass New York portal are your starting points.
New Jersey
New Jersey has a slightly tighter window and some unique tools available.
- Deadline: 120 days from the violation date
- Dispute method: Online via the violation number and license plate lookup
- For NJ account holders: Use the C-1 section to link violations directly to your account
- For out-of-state drivers: Follow the C-2 instructions on the notice
New Jersey also offers an Immediate Payment option through the mobile app or website. This feature transfers funds in near real time from your bank account, bypassing the standard 3-day ACH clearing window. It helps resolve toll bills before they escalate into violations.
Visit the E-ZPass NJ website or the Immediate Payment FAQ for details.
Pennsylvania
Pennsylvania enforces the strictest timelines in the network.
- Deadline: 45 days from the transaction date (disputes older than 90 days face summary rejection)
- Dispute method: Online via the PA Turnpike dispute portal
Required documentation depends on the type of error:
| Dispute Type | Documentation Needed |
|---|---|
| Vehicle classification error | Current vehicle registration |
| Duplicate charge | Statements showing both identical transactions |
| Video toll (V-Toll) | Entry interchange documentation |
| Emergency mission | Official mission number and travel code |
Submit all disputes at the PA Turnpike E-ZPass Dispute page.
Virginia
Virginia presents a unique challenge because tolling is split among multiple operators. The Dulles Toll Road and I-64 Express Lanes are managed by different public and private entities.
- Deadline: 30 days from the issue date for notices from the Virginia Toll Violation Processing Center
- Dispute method: Online portal using your account number and transponder number (exclude the first three digits after the asterisk when entering your tag ID)
- Complex violations: Require a notarized Violation Dispute Affidavit (forms beginning with “VN” or “VF”) with the exact date, time, and location of the incident
Visit the Toll Roads in Virginia FAQ page or the E-ZPass Virginia document library for the correct forms.
The Toll Payer Advocate: Your Escalation Option
If your dispute gets denied and you still believe the charge is wrong, do not give up. Several states operate an independent Office of the Toll Payer Advocate (TPA). This office investigates unresolved billing issues free of charge and works separately from the Customer Service Centers.
The TPA is designed for cases like the Pennsylvania plate misread crisis and the RJL Trucking lawsuit, where a systemic error affected many accounts at once. In 2024 and 2025, RJL Trucking identified over $100,000 in improper commercial overcharges, including a six-axle truck billed at 30% above published rates. When the primary errors drained their account, they were hit with an additional $10,000 in “insufficient funds” fees. The TPA exists precisely for situations like this.
How to reach the TPA:
- New York (PANYNJ): panynj.gov/tpa.html
- New York (Thruway): thruway.ny.gov/travelers/toll-payer-advocate
- E-ZPass NY resources: e-zpassny.com/tbm/tpa
- Phone (NY): 800-333-8655
- Phone (NJ): 888-288-6865
Important: The TPA is a last resort. You must first attempt resolution through the standard Customer Service Center and document your failed attempts before the TPA will open an investigation. If your registration is already suspended, the matter falls under the DMV’s jurisdiction, and the TPA generally cannot intervene.
How to Prevent Future Billing Errors
The majority of billing errors are preventable. A few simple habits make a big difference.
Keep Your Account Information Current
New York State law requires you to update your registration address with the DMV within 10 days of moving. Because E-ZPass systems pull data from DMV records, an outdated address means toll notices never reach you. By the time you find out about unpaid tolls, the debt may have grown to hundreds or thousands of dollars.
CBS News New York reported on a Staten Island resident who faced this exact situation, with a small oversight spiraling into a multi-thousand dollar problem.
Check That All Your Plates Are Linked
One of the most common errors occurs when a driver has a funded E-ZPass account but still receives a mail bill at the higher video toll rate. This usually happens because the license plate was never added to the account profile.
To prevent this:
- Log in to your E-ZPass account and verify every license plate listed
- Resolve any Toll-by-Mail invoices by visiting the Tolls by Mail website and selecting “Resolve Toll Bill (E-ZPass Customers)”
- Use a Temporary Travel Account if you have already traveled without an account (available in New York, lets you pay using plate info and travel dates before a bill is mailed)
Keep Your Transponder in Good Shape
- Mount it correctly (one inch below the roofline, one inch right of the rearview mirror support)
- Never hold it by hand while passing under a gantry
- Replace aging transponders every 5 to 7 years; most agencies provide replacements for free
- If your windshield has metallic tinting or a heating element, you may need an external plate-mounted transponder
Watch Your Replenishment Settings
Your account’s replenishment point is recalculated every 90 days based on average usage. If your driving suddenly increases, your balance can hit zero before the next cycle, triggering “Invalid Tag” messages and $50 fees per occurrence.
If you pay by checking account (ACH), a single failed transaction can also trigger a $25 returned check fee. Review your replenishment threshold in your account settings if your commute changes significantly.
Looking Ahead: What Is Changing in 2027
The tolling industry is moving toward stronger consumer protections. Proposed legislation called the “Toll Payer Protection Act” would require:
- A formal three-notice procedure before any violation is issued
- Written decisions on all appeals within 30 days
- Time-stamped photos included on every invoice
The transition to Open Road Tolling (ORT) continues across more states. Gantries now read plates at full highway speed, which raises the stakes for correct transponder mounting and up-to-date plate registration.
States are also building more transparent digital dashboards and faster payment tools to reduce the friction that leads to large late fee crises. The goal is a system where an honest mistake stays a small problem, instead of becoming a financial emergency.
Stop the Charge Before It Grows
E-ZPass billing errors are frustrating. They can also be expensive if you ignore them. The key is to act fast, document everything, and contact the right agency.
Here is your action checklist:
- Review your statement at least once a month
- Screenshot any suspicious charge immediately
- Note the transaction ID, date, amount, and plaza
- Contact your issuing agency before the dispute deadline
- If denied, escalate to the Toll Payer Advocate
- Never click links in unsolicited toll payment texts
- Keep your account address, plates, and payment method current
