What Pay-By-Plate Tolls Are and How They Work

Pay-By-Plate is Florida's system for collecting tolls from drivers who do not have a transponder or toll tag. Instead of stopping at a booth or using a mounted device, a camera photographs your license plate as you pass through a toll plaza. The toll authority then mails an invoice to the vehicle owner's address on file with the Florida Department of Highway Safety and Motor Vehicles.

This system operates on most of Florida's toll roads, including the Florida Turnpike, Sunpass toll plazas, and many local toll roads. The camera captures your plate number, and the toll authority matches it to your vehicle registration to find your mailing address. You receive a bill weeks later, not at the moment you drive through.

Pay-By-Plate is not a choice you make in advance—it is what happens automatically if you drive through a toll plaza without a transponder. You do not register for it or sign up. The system straightforward processes your toll and sends you the bill.

Key Takeaways

  • Pay-By-Plate tolls are billed by mail to the address on your vehicle registration, and you have no choice whether to use this system if you lack a transponder.
  • Toll invoices typically arrive within two to four weeks of driving through a toll plaza, and payment is due within a set number of days from the invoice date.
  • If you drive through tolls regularly, a SunPass or other transponder is cheaper than paying per-plate fees, which include a processing charge on top of the toll itself.
  • Unpaid toll bills can result in late fees, suspension of your vehicle registration, and a hold on your driver's license renewal.
  • If your registration address is incorrect or you moved, update it with the DHSMV when ready so toll bills reach you on time.

How Much Pay-By-Plate Tolls Cost

The toll amount itself depends on which road you use and how far you travel. The Florida Turnpike, for example, charges different rates for different segments. However, Pay-By-Plate adds a processing fee on top of the base toll—typically $1.50 to $2.50 per transaction, depending on the toll authority.

This processing fee is why a transponder saves money over time. A SunPass transponder costs nothing to obtain and eliminates the processing fee entirely. If you drive through tolls once or twice a year, Pay-By-Plate is acceptable. If you use tolls weekly or more, the processing fees add up quickly and a transponder becomes the cheaper option.

You can find the exact toll rates and processing fees for specific roads on the Florida Department of Transportation website or by contacting the toll authority that operates the road you used. Each authority sets its own rates within state guidelines.

When Your Toll Invoice Arrives and How to Pay

After you drive through a toll plaza, the camera system processes your plate. The toll authority then matches your plate to your vehicle registration and mails an invoice to the address on file with the DHSMV. This process typically takes two to four weeks.

The invoice will show the toll amount, the processing fee, the date and time you passed through, and the toll plaza location. It will also state a payment important date—usually 30 days from the invoice date. You can pay by mail by returning the invoice with a check, or by phone or online using the toll authority's website.

Pay when ready when you receive the invoice. Waiting until the last day is risky because mail delays can cause your payment to arrive late, triggering late fees and additional penalties.

What Happens If You Do Not Pay a Toll Bill

Unpaid toll bills carry real consequences for your driving privileges and vehicle registration. If you do not pay within the important date, the toll authority adds a late fee—typically $25 to $50 per unpaid toll—and may refer the debt to a collection agency.

More seriously, unpaid tolls can trigger a registration suspension. The Florida Department of Highway Safety and Motor Vehicles will not renew your vehicle registration until the toll debt is paid. You also cannot renew your driver's license if you have an outstanding toll debt. Driving with a suspended registration is illegal and can result in a traffic citation, fines, and vehicle impoundment.

If you receive a toll bill you believe is incorrect—for example, you used a transponder but were still billed—contact the toll authority when ready with proof. Do not ignore the invoice. Disputing a bill takes time, and the important date still applies while your dispute is being reviewed.

Keeping Your Registration Address Current

Pay-By-Plate tolls are mailed to the address on your vehicle registration with the DHSMV. If you move and do not update your address, toll invoices will go to your old address and you will not receive them. The toll authority will still consider the bill unpaid, and penalties will accumulate without your knowledge.

Update your registration address with the DHSMV when ready after you move. You can do this online through the DHSMV website, by mail, or in person at a local tax collector's office or DHSMV service center. Updating your address takes only a few minutes and prevents toll bills from getting lost in the mail.

If you have moved recently and suspect you may have missed a toll bill, contact the toll authority that operates the road you used and provide your new address. They can tell you whether any unpaid tolls are on record and help you settle them before registration suspension occurs.

Getting a Transponder to Avoid Pay-By-Plate Fees

SunPass is Florida's official transponder program and is the easiest way to avoid Pay-By-Plate processing fees. A SunPass transponder is a small device that mounts on your windshield and communicates with toll plazas as you pass through. You prepay tolls into a SunPass account, and the transponder deducts the toll automatically. No invoice, no processing fee, no late bills.

You can obtain a SunPass transponder online at the SunPass website, by phone, or at a SunPass customer service center. The transponder itself is free. You straightforward set up an account, add prepaid funds, and mount the device on your windshield. When your balance runs low, you can reload it online or by phone.

If you use tolls regularly—more than once a week—a SunPass transponder pays for itself within a few months by eliminating processing fees. Even if you use tolls only occasionally, the transponder removes the risk of missing a bill or having an invoice lost in the mail.

Disputing an Incorrect Toll Bill

If you receive a Pay-By-Plate invoice you believe is wrong, contact the toll authority that issued it as soon as possible. Common reasons for disputes include being billed twice for the same passage, being charged for a toll you did not pass through, or being billed despite having a valid transponder.

When you contact the toll authority, have your invoice in hand and be ready to explain why you believe the charge is incorrect. Provide any evidence you have—for example, a receipt showing you used a transponder, or a credit card statement showing you were elsewhere at the time. The toll authority will review your dispute and either remove the charge or explain why it is valid.

The dispute process can take several weeks. During this time, the payment important date on your invoice still applies. Pay the bill by the important date to avoid late fees, and note in your payment that you are disputing the charge. Once the toll authority resolves your dispute, they will refund any overpayment.

Frequently Asked Questions

Can I get a refund if I paid a toll twice by mistake?

Yes. Contact the toll authority that issued the duplicate charge with your invoice and proof of payment. Provide the dates and toll plaza locations. The toll authority will review the transaction records and issue a refund if the duplicate is confirmed. This process typically takes two to four weeks.

What if I moved and did not get my toll bill?

Contact the toll authority when ready and provide your new address. Ask them to check for any unpaid tolls on record under your license plate. If bills were sent to your old address, the toll authority may be able to reissue them or work with you on payment arrangements before registration suspension occurs.

Do I have to use Pay-By-Plate or can I get a transponder instead?

You do not have to use Pay-By-Plate. If you obtain a SunPass transponder before you drive through tolls, you will be charged via the transponder instead and will not receive a Pay-By-Plate invoice. The transponder is free and eliminates processing fees.

Will unpaid tolls affect my credit score?

Unpaid tolls can be referred to a collection agency, which may report the debt to credit bureaus and damage your credit score. However, the when ready consequence is registration and license suspension, which happens before a collection agency becomes involved. Pay toll bills promptly to avoid both penalties.

Can I pay tolls with a credit card at the plaza instead of using Pay-By-Plate?

Most Florida toll plazas do not accept payment at the booth. Pay-By-Plate is the default system for drivers without a transponder. Your only way to avoid Pay-By-Plate is to obtain a SunPass transponder or another accepted toll tag before you drive through.
