SunPass is Florida's electronic toll collection system that charges your account automatically when you drive through tolled roads

SunPass is a prepaid account system run by the Florida Department of Transportation. When you have an active SunPass account, sensors at toll plazas read a small transponder mounted on your windshield and deduct the toll amount from your balance. You don't stop, don't pay cash, and don't receive a bill for each crossing — the system handles it automatically.

The system covers most of Florida's toll roads, including the Florida Turnpike, Suncoast Parkway, Beachline Expressway, and many county toll roads. If you drive tolled roads regularly in Florida, having a SunPass account usually costs less per crossing than paying cash at a toll booth, because electronic tolls are discounted compared to cash rates.

Key Takeaways

  • SunPass requires you to set up a prepaid account and mount a transponder on your windshield before you can use tolled roads.
  • Electronic tolls through SunPass cost less per crossing than paying cash, and you never have to stop at a toll booth.
  • You can open a SunPass account online, by phone, or in person, and you must add money to your account before driving.
  • If your balance runs low, the system sends you a notice and you can add funds online, by phone, or by mail.
  • If you don't pay tolls owed, Florida can suspend your vehicle registration and send your account to a collection agency.

How to open a SunPass account

You can open an account through the official SunPass website (sunpass.com), by calling 1-888-SUNPASS (1-888-786-7277), or at a SunPass customer service center. You'll need your vehicle's license plate number, a valid driver's license or ID, and a payment method (credit card, debit card, or bank account).

When you open the account, you choose how much money to deposit upfront — this becomes your prepaid balance. The minimum varies but is typically $25 to $50. You'll also receive a transponder in the mail or pick one up at a service center. The transponder is a small device that mounts on your windshield and communicates with toll plaza sensors. Once you receive it, you activate it through your online account or by phone, and it's ready to use.

If you own multiple vehicles, you can add more transponders to the same account or open separate accounts. Each transponder is linked to one vehicle's license plate.

Toll rates and how much you'll pay

SunPass toll rates depend on which road you're using and how far you travel. The Florida Turnpike, for example, charges different amounts for different segments. Rates also vary by vehicle type — cars, motorcycles, and trucks pay different amounts. Electronic toll rates (what you pay with SunPass) are typically 25 to 50 percent lower than cash rates at the same plaza.

You can look up specific toll amounts on the SunPass website by entering your starting point and destination. The system shows you both the SunPass rate and what you would pay in cash. Your account balance decreases each time you pass through a toll plaza, and you receive an itemized statement online showing every crossing, the date, time, location, and amount charged.

Adding money to your account and low-balance notices

When your SunPass balance drops below a certain threshold (usually around $10), the system sends you a notice by email or mail. You don't have to wait for this notice to add funds — you can add money anytime through your online account, by calling customer service, or by mailing a check to SunPass.

Online and phone payments are processed immediately or within one business day. If your balance reaches zero while you're driving, you'll receive a violation notice in the mail for that crossing. You can then add funds to cover the toll plus any applicable fees. If you ignore violation notices and don't pay, your account goes to collections and Florida can suspend your vehicle registration.

What happens if you don't pay tolls

If you drive through a toll plaza without a working transponder or without sufficient balance in your SunPass account, you receive a toll violation notice. The notice includes the toll amount, a processing fee (typically $2.50), and instructions for payment. You have a deadline to pay, usually 30 days from the notice date.

If you don't pay the violation, SunPass reports the debt to a collection agency and the Florida Department of Highway Safety and Motor Vehicles. The state can then suspend your vehicle registration, meaning you cannot legally renew it. You'll also face additional collection fees and interest. Paying the original toll and fees promptly is much simpler than dealing with a suspended registration.

Using SunPass with a rental car or borrowed vehicle

If you rent a car in Florida, the rental company usually provides a transponder or can add one to your rental agreement. You'll pay a daily rental fee for the transponder (typically $3 to $5 per day) plus the actual tolls, and these charges appear on your rental bill. Some rental companies allow you to use your own SunPass transponder if you update your account to reflect the rental vehicle's license plate temporarily.

If you borrow someone else's car, you can use their SunPass transponder if they've authorized it on their account. Alternatively, you can pay tolls in cash at most plazas, though you'll pay the higher cash rate. Some toll roads now also accept payment by license plate — you can pay online within a few days after crossing without a transponder, though this also costs more than SunPass rates.

Managing your account online

The SunPass website lets you view your account balance, transaction history, add funds, update your payment method, and manage multiple vehicles or transponders. You can also set up automatic replenishment, which adds a set amount to your account whenever the balance drops below a threshold you choose. This prevents your balance from reaching zero and eliminates the need to manually add funds.

If your transponder stops working or is damaged, you can request a replacement through your online account or by phone. Replacements are usually free or cost a small fee. You can also pause your account temporarily if you won't be driving tolled roads for a while, which prevents your balance from expiring.

Frequently Asked Questions

Can I use my SunPass account in other states?

SunPass works only on Florida toll roads. However, Florida has reciprocal agreements with other states' toll systems, so if you travel to Georgia, North Carolina, or other states with compatible systems, you may be able to use your transponder there. Check the SunPass website for current reciprocal agreements and which out-of-state roads accept SunPass.

What if I move out of Florida but still owe tolls?

You remain responsible for any unpaid tolls. SunPass can pursue collection through a collection agency, and if your vehicle is registered in Florida, the state can suspend that registration. If you've moved and your vehicle is now registered in another state, contact SunPass to discuss payment options and avoid future registration issues if you return to Florida.

How long does a SunPass transponder last?

Transponders typically last 5 to 7 years before the battery or internal components fail. When your transponder stops working, you'll notice toll violations appearing on your account. Contact SunPass to request a replacement, which usually arrives within 7 to 10 business days. Keep your old transponder until the new one arrives and is activated.

Can I get a refund if I have money left in my SunPass account?

Yes. If you close your account, SunPass refunds any remaining balance to the payment method you used to fund it. The refund typically takes 7 to 10 business days. Contact customer service to close your account and request the refund.

What if a toll was charged twice by mistake?

Review your transaction history on the SunPass website. If you see a duplicate charge, contact customer service with the date, time, and location of the crossing. SunPass investigates duplicate charges and issues refunds when warranted. Keep documentation of your crossing (photos, receipts, or witness information) if you believe an error occurred.
