Florida tolls are paid through three main systems: SunPass (the state's official program), toll-by-plate (automatic billing by mail), and cash at toll booths

When you drive on Florida's toll roads, bridges, and expressways, you have choices about how to pay. SunPass is Florida's electronic toll collection system—you mount a small transponder on your windshield, and tolls are deducted from a prepaid account as you pass through toll plazas. Toll-by-plate means the toll authority photographs your license plate and bills you by mail. Cash payment is still available at some toll booths, though many plazas have eliminated cash lanes entirely.

Which system you use affects how much you pay, how quickly you're charged, and whether you get discounts. Most drivers who use toll roads regularly end up with SunPass because the per-toll cost is lower. If you don't have SunPass and drive through a toll plaza, the toll-by-plate system automatically kicks in—you don't have to do anything, but you'll pay a higher rate and receive an invoice weeks later.

Key Takeaways

  • SunPass is Florida's official electronic toll system and offers the lowest per-toll rates, with discounts ranging from 25 to 50 percent depending on the road.
  • Toll-by-plate charges you a higher rate and sends an invoice by mail if you don't have a transponder, so regular toll road users save money with SunPass.
  • You can buy a SunPass transponder online, by mail, or at retail locations, and it takes a few days to set up before you can use it.
  • Tolls vary by road and time of day on some expressways, and rates change periodically—check your specific toll road's website for current prices.
  • If you receive a toll invoice you believe is wrong, you can dispute it through the toll authority that issued it within a set timeframe.

How SunPass works and what it costs

SunPass is operated by the Florida Department of Transportation and works by reading your transponder as you pass through a toll plaza. You prepay money into your account, and each toll crossing deducts the appropriate amount. The transponder itself is free or costs a small one-time fee depending on where you get it, but the real savings come from the discount rate you receive on every toll.

Discount rates vary by road. On the Florida Turnpike, SunPass users typically pay 25 to 50 percent less per toll than toll-by-plate drivers. On some express lanes and newer toll roads, the discount can be even steeper. Your account balance is deducted when ready when you pass through, so you know right away how much you've spent.

You can set up automatic replenishment so your account refills when the balance drops below a threshold you choose. This means you won't accidentally run out of money and get charged the higher toll-by-plate rate. Most drivers set it to refill at $10 or $25 remaining, depending on how often they use tolls.

Getting a SunPass transponder

You can obtain a SunPass transponder in three ways: order online at the SunPass website, call 1-888-SUNPASS (1-888-786-7277), or visit a retail location. Retail partners include Publix Super Markets, Winn-Dixie, and some gas stations throughout Florida. Online ordering typically arrives within five to seven business days, and you'll need to set up it before using it on toll roads.

When you order, you'll provide your vehicle information and payment method for your prepaid account. The transponder itself is usually free for standard models, though specialty transponders (like those for motorcycles or RVs) may have a small fee. Once it arrives, you mount it on your windshield following the included instructions—placement matters because the toll plaza's reader needs a clear signal.

set up happens online or by phone and typically takes 24 to 48 hours. Until your transponder is active, it won't work at toll plazas, and you'll be charged the toll-by-plate rate if you drive through. Check your account status before your first toll trip to confirm set up is complete.

Toll-by-plate charges and how to avoid them

If you drive through a Florida toll plaza without a working SunPass transponder, the toll authority photographs your license plate and sends you an invoice by mail. This toll-by-plate charge is significantly higher than the SunPass rate—often 50 to 100 percent more per crossing, depending on the road. You'll receive the invoice weeks after you drive through, with payment instructions and a due date.

Toll-by-plate is meant as a backup system for occasional out-of-state drivers or people who forgot their transponder. If you live in Florida and use toll roads regularly, toll-by-plate becomes expensive quickly. A single toll might cost $2.50 with SunPass but $4.00 or more with toll-by-plate. Over a month of commuting, that difference adds up to hundreds of dollars.

Some toll roads have eliminated cash lanes entirely, so toll-by-plate is your only option if you don't have SunPass. This is especially true on express toll lanes and newer expressways. If you're a frequent toll road user, getting SunPass before your first trip saves money when ready.

Toll rates, discounts, and how they change

Florida toll rates are set by the individual toll authorities that operate each road or expressway. The Florida Turnpike Enterprise, Miami-Dade Expressway Authority, Central Florida Expressway Authority, and others each manage their own tolls and set their own rates. This means the cost of a single toll crossing varies depending on which road you're on, how far you travel, and sometimes what time of day you drive.

Some expressways use dynamic pricing, meaning tolls are higher during peak traffic times and lower during off-peak hours. This is common on express lanes designed to manage congestion. Your SunPass account shows the exact toll charged for each crossing, so you can see the variation over time.

Toll rates increase periodically to fund road maintenance and improvements. When rates change, SunPass users are notified in advance, and the new rates take effect on a set date. Check your specific toll road's website or your SunPass account for current rates, as they vary widely across Florida's system.

What to do if you receive a toll invoice you think is wrong

If you receive a toll-by-plate invoice and believe the charge is incorrect—perhaps you had SunPass active, the amount seems wrong, or you weren't driving that vehicle—you can dispute it. Contact the toll authority that issued the invoice. The invoice itself lists the authority's name and phone number or website.

Disputes must usually be filed within 30 days of the invoice date, though this varies by authority. Gather any evidence you have: your SunPass account statement showing you had an active transponder, proof you weren't in Florida on that date, or documentation that your vehicle was sold or not in service. Submit your dispute in writing or through the toll authority's online portal if available.

The toll authority will review your dispute and respond within a set timeframe, typically 30 to 60 days. If they find the charge was in error, they'll cancel the invoice or issue a refund. If they uphold the charge, you'll receive an explanation of why. If you disagree with their decision, some authorities allow a second level of appeal.

SunPass account management and troubleshooting

You can manage your SunPass account online or by phone. Log into your account to check your balance, view recent toll transactions, update your payment method, or adjust your automatic replenishment settings. The online portal shows which toll road you used, the date and time, and the exact amount charged.

If your transponder stops working—perhaps it was damaged or the battery died—you can order a replacement through your account. Replacement transponders are usually free, and a new one will arrive within a week. In the meantime, you'll be charged the toll-by-plate rate if you use toll roads.

If you move out of Florida or no longer use toll roads, you can close your SunPass account online. Any remaining balance will be refunded to your original payment method, typically within 7 to 10 business days. If you're moving to another state with its own toll system, check whether that state recognizes Florida SunPass transponders—some do, and some don't.

Frequently Asked Questions

Can I use my SunPass transponder in other states?

Some states recognize SunPass through reciprocal agreements, but not all. Georgia, North Carolina, and a few others accept it. Before traveling, check the toll authority's website for the state you're visiting. If they don't accept SunPass, you'll be charged toll-by-plate rates.

What happens if my SunPass account runs out of money?

If your balance drops to zero and you drive through a toll plaza, you'll be charged the toll-by-plate rate instead of the SunPass rate. You'll receive an invoice by mail for that crossing. Set up automatic replenishment to avoid this—most drivers choose to refill when the balance reaches $10 or $25.

Do I need a separate SunPass for each vehicle?

Yes, each vehicle needs its own transponder. You can link multiple transponders to one account and manage them all in one place. This is useful if you have two cars or a household with multiple drivers.

How long does it take to get a SunPass after I order it?

Online orders typically arrive within five to seven business days. Retail purchases are when ready, but you still need to set up the transponder before using it, which takes 24 to 48 hours. Plan ahead if you're traveling soon.

Can I get a refund if I overpaid my SunPass account?

Yes. If your account has a balance remaining when you close it or request a refund, the money will be returned to your original payment method within 7 to 10 business days. Contact SunPass customer service to request the refund.
