SunPass Toll-By-Plate Explained (2026): Florida’s Pay-Per-Use Tolling Made Simple

You just got a bill in the mail from the Florida Department of Transportation. The problem? You had no idea you even drove on a toll road. Welcome to Toll-By-Plate, Florida’s “we saw your car, we’ll send you the bill later” system.

It sounds sneaky, but it is actually pretty simple once you understand how it works. This guide covers everything you need to know so you are never caught off guard again.

What Is SunPass Toll-By-Plate?

Toll-By-Plate is Florida’s backup tolling method for drivers who do not have a SunPass transponder. When you pass through an all-electronic toll plaza without a valid transponder, cameras capture your license plate. The system then matches your plate to your vehicle registration and mails you an invoice.

No booths. No coins. No fumbling for change. Just a bill that shows up a few weeks later.

Think of it as tolling on autopilot. Convenient in theory, but more expensive in practice.

By 2026, Florida operates over 734 miles of tolled facilities, making it the most extensive toll network in the United States. Nearly all of it is all-electronic, meaning Toll-By-Plate is no longer the exception. It is the universal safety net for anyone without a prepaid account.

How Does Toll-By-Plate Work?

Understanding the mechanics helps you avoid surprises. The process moves through three clear stages.

Stage 1: The Camera Captures Your Plate

Every toll gantry on Florida’s expressway network has high-resolution cameras overhead. When your vehicle passes through without a valid transponder signal, the system triggers those cameras within milliseconds. They photograph your front and rear license plate and log your entry and exit point.

The technology uses Optical Character Recognition (OCR) software to read your alphanumeric plate number. It is surprisingly accurate, even in rain or poor lighting.

Stage 2: Your Registration Gets Looked Up

Once your plate is captured, the toll operator submits it to the Florida Department of Highway Safety and Motor Vehicles (FLHSMV). The FLHSMV pulls the registered owner’s address from their database.

This works for out-of-state plates too. Florida has access to equivalent out-of-state registries, so visitors are not off the hook.

Stage 3: You Receive an Invoice by Mail

Your tolls accumulate over a 30-day window. At the end of that period, a Toll Enforcement Invoice is generated and mailed to your registered address. From there, you have 30 days to pay before the account enters delinquency status.

The invoice includes:

• The toll amount for each transaction
• The date and location of each toll
• A payment due date
• A payment link and mailing address

Toll-By-Plate vs. SunPass: The Real Cost Difference

This is where it gets important. Toll-By-Plate costs more than using a SunPass transponder. The state charges a premium because processing physical invoices costs more than automated transponder deductions.

Here is how the two compare:

The $2.50 fee applies per invoice, not per toll. However, the base toll rate itself is also higher. On some regional bridges and expressways, Toll-By-Plate rates can run 50% to 150% higher than transponder rates.

Over time, that adds up fast.

Who Gets a Toll-By-Plate Bill?

More people than you might think. The most common situations include:

• Tourists and rental car drivers who do not realize Florida’s highways are nearly cashless
• New Florida residents who have not set up a SunPass account yet
• Drivers with a dead or malfunctioning transponder
• Out-of-state visitors passing through on I-4, SR-528, or the Florida Turnpike

If you fall into any of these groups, expect a bill in the mail within a few weeks of your trip.

Watch Out: Express Lanes Do Not Accept Toll-By-Plate

This is the most important rule many drivers do not know. Toll-By-Plate is completely prohibited in Florida’s Managed Lanes and Express Lanes. These lanes require a valid transponder, full stop.

I-4 Express Lanes in Orlando

The I-4 Express Lanes cover 21 miles through the Orlando metro area. They use dynamic pricing and a transponder-only payment model.

If you enter without a valid SunPass, E-PASS, or interoperable transponder, you do not just get an invoice for the toll. You get a $25.00 violation fine plus the cost of the toll for each segment you travel.

Here is a quick breakdown of how I-4 Express pricing works:

One more thing worth knowing: the toll price is locked in the moment you enter the lane, based on the rate displayed on the overhead sign. If traffic gets worse while you are inside, that higher rate only hits drivers who enter after the update.

Jacksonville I-295 Express Lanes

The I-295 Express Lanes in Jacksonville follow similar rules during peak hours. They are toll-free outside peak times, but between 6 a.m. and 10 a.m. and 3 p.m. and 7 p.m. on weekdays, a transponder is mandatory.

Driving through without one during those windows? Same $25.00 fine.

Rental Cars and Toll-By-Plate: A Costly Combination

Travelers landing at Orlando International (MCO) or Miami International (MIA) often run into nasty surprises involving rental car toll programs. Rental companies handle tolls in a few different ways, and none of them are cheap.

The Daily Convenience Fee Model

Many rental agencies automatically enroll their vehicles in a toll program. If you trigger even a single toll, the agency charges the full Toll-By-Plate rate plus a daily convenience fee for every day of your rental, not just the days you used a toll road.

These daily fees typically run $4.95 to $11.99 per day.

The Per-Toll Administrative Fee Model

Some agencies charge a processing fee per individual toll instead. That fee can range from $5.00 to $15.00 per gantry. On a route like SR-408 in Orlando, which has multiple gantries, the fees alone can easily hit $50.00 for a single drive.

The Smart Move: Bring Your Own Transponder

The best strategy for rental car drivers is the “Bring Your Own Transponder” approach. Here is how to do it correctly:

1. Opt out of the rental company’s toll program at pick-up. Do this explicitly and get confirmation.
2. Add the rental vehicle’s license plate to your personal SunPass or E-PASS account. Include the specific start and end dates of your rental. You can do this at SunPass.com.
3. Shield the rental car’s built-in transponder if it has one. Many vehicles have a sliding lead-lined box for this. Keep it closed to prevent double billing.
4. Keep your rental agreement and photograph the shielded transponder as evidence in case a dispute comes up.

This approach lets you pay the lower transponder rate and avoid the daily rental fees entirely.

Choosing the Right SunPass Transponder

If you spend any time driving in Florida, getting a transponder is the obvious move. By 2026, there are two main hardware options.

SunPass Mini

• Price: $4.99 plus tax
• Permanently sticks to the inside of your windshield
• Cannot be moved between vehicles
• Works on Florida, Georgia, North Carolina, Texas, Oklahoma, and Kansas toll roads
• Best for residents with one dedicated vehicle

SunPass PRO

• Price: $14.95 plus tax
• Portable unit with a suction cup mount
• Can move between vehicles, including rental cars
• Works anywhere E-ZPass is accepted, covering 24+ states
• Best for travelers, commuters with multiple vehicles, or frequent rental car users

You can buy either option at retailers like Publix, CVS, and 7-Eleven, or directly through SunPass.com.

What About E-ZPass?

Florida is fully integrated with the E-ZPass Interagency Group. That means if you already have an E-ZPass from New York, Massachusetts, or another participating state, it works in Florida at the same discounted rates as SunPass. No second transponder needed.

Here is a quick look at the main transponder options and their coverage:

What Happens If You Do Not Pay a Toll-By-Plate Invoice?

Ignoring a Toll-By-Plate invoice is a bad idea. Florida takes unpaid tolls seriously, and the consequences escalate quickly. Here is the full path from first notice to serious legal trouble:

1. First Notice: Standard Toll Enforcement Invoice with a $2.50 fee. Payment due within 30 days.
2. Second Notice: Issued if the first goes unpaid. Additional late fees are added.
3. Collections Referral: The debt transfers to a private collection agency, which adds further charges to your balance.
4. Uniform Traffic Citation (UTC): A formal citation may be issued, requiring a court appearance or payment of a fine that often exceeds $100.

The Registration Stop

The most powerful enforcement tool Florida uses is the Registration Stop. If you have outstanding toll debt, the tolling agency can notify the FLHSMV to place a hold on your vehicle’s registration renewal.

That means you cannot legally drive the vehicle once your current plate expires until every dollar of toll debt and fees is paid in full. The hold can take several business days to clear even after payment.

You can check for active registration stops on the Florida’s Turnpike Unpaid Tolls page by entering your plate and zip code.

How to Pay a Toll-By-Plate Invoice

Paying is genuinely simple. You have several options:

• Online: Visit SunPass.com or the toll authority’s invoice portal. This is the fastest method and accepts most major credit cards.
• By phone: The number appears on your invoice.
• By mail: Use the return envelope included with your invoice.
• In person: SunPass Walk-in Centers are available in Brandon, Orlando, and Boca Raton.

If you think the invoice is an error, you can dispute it. Log in to your SunPass account and view the photo of the license plate associated with the toll. Common errors include misread plates due to dirt, plate frames, or bad weather. The SunPass FAQ page walks through the dispute process in detail.

The Toll Relief Program Is Over: What That Means in 2026

From 2023 through March 2025, Florida ran a statewide Toll Relief Program that gave frequent commuters with 35 or more transactions per month an automatic 50% account credit. It saved drivers millions. Then it ended.

The Florida Toll Relief Program expired on March 31, 2025, and the 50% rebate is gone. What remains is the standard 25% average discount that SunPass users get compared to Toll-By-Plate rates.

Here is how the two eras compare:

Some regional authorities have launched their own loyalty programs to fill the gap. The Central Florida Expressway Authority reinstated its Volume Savings Program for E-PASS users. However, your actual savings in 2026 depend heavily on which specific roads you use most.

Special Exemptions: Disabled Drivers and Veterans

Florida does provide toll exemptions for certain groups, but the process is not automatic through Toll-By-Plate.

Disabled Toll Permits

Individuals with severe upper-limb impairments who drive specially equipped vehicles qualify for a complete toll exemption. However, the exemption does not work through plate-based billing because the camera cannot identify the driver’s physical status.

To use electronic lanes toll-free, a qualifying driver must apply for a Non-Revenue SunPass Mini Transponder, which is coded to trigger a zero-dollar transaction at the gantry. The full details are in the 2026 FDOT Disabled Toll Permit brochure.

Veterans Initiatives

The 2026 Legislative Session introduced Senate Bill 228, which proposes a pilot program for discounted tolls for Certified Veteran Business Enterprises. It reflects a growing trend of using the toll system for targeted economic incentives beyond just infrastructure funding.

SunPass Plus: More Than Just Toll Roads

By 2026, the SunPass transponder has become a broader Florida travel pass. The SunPass Plus Parking program is now active at all major Florida airports, including MCO, MIA, FLL, TPA, and PBI, as well as high-traffic venues like Hard Rock Stadium.

When you enter a SunPass Plus parking facility, the gantry records your entry and exit times. The parking fee is automatically deducted from your prepaid toll balance. No paper tickets, no waiting at kiosks, no fumbling for a credit card on the way out.

If you travel through Florida airports regularly, this alone makes the SunPass worthwhile.

Quick Reference: Toll-By-Plate Fast Facts

Your Florida Road Trip Starts Here

Toll-By-Plate is not a trap. It is Florida’s way of making sure the highways stay funded even when drivers skip the transponder step. Pay your invoice on time, and the system causes zero problems. But if you drive in Florida with any regularity, the math strongly favors getting a SunPass.

The Mini costs $4.99. The PRO costs $14.95. Either one saves you money on every single toll, keeps you out of Express Lane trouble, and eliminates the surprise bills altogether.

Get the transponder, load it up, and enjoy the drive. Florida has no shortage of sunshine. You do not need a stack of toll invoices adding stress to the trip.
