Confused about the cheapest way to pay tolls when renting a car? The trick to saving money is to avoid car rental toll charges. Rental companies charge through the nose for electronic toll billing programs such as E-ZPass or FasTrak, which is why it made our list of ways car rental companies rip you off. Be aware that when car rental companies rent you transponders, they often charge per day of the rental. So if you only go through a toll or two on a five-day trip, you’ll still be charged for five days of the service.

Moreover, you have to worry about more than just the tolls themselves, as surcharges from the rental company can add up fast. This is an issue to pay attention to, since the surcharge can vary greatly, from as little as $2.95 per day to as much as $25 per toll. 

Consider the sad tale of the retired teacher from Michigan who took a family trip to Texas and got a rude surprise when he returned his rental car. “His toll bill from tolls: $9.96. His bill from [the now-bankrupt] Advantage Rent a Car: $102.37. The difference: $92.41, or the $12.99 daily pass fee for six days plus taxes and fees,” according to the Chicago Times.

Rental Car Charges for Toll Transponders

  • Hertz charges a $5.95 fee (plus the toll) for every day you use a toll road.
  • Avis and Budget charge a $5.95 fee for every rental day to a $29.75 maximum per rental—plus the tolls, of course.
  • Alamo, National and Enterprise give you the same choice. You can pay $3.95 to $4.95 per usage day up to a maximum charge of $19.75 for the rental period.
  • Payless works similarly to sister companies Avis and Budget, but it’s a little cheaper at $2.95 per day, up to a $14.75 maximum fee.

  • Dollar and Thrifty offer an all-inclusive option for $10.49 per rental day (or $52.49 per week) that includes all tolls. Decline it, though, and any toll you fail to pay in cash will cost you a $15 administrative fee per toll—ouch!
  • Fox offers a similar product as Dollar and Thrifty in some areas, but the price varies—$8.99 per day in Florida and $11.49 per day in Northern California.
  • Sixt offers a toll program for $7.99 per day, with a maximum of $119 per rental. If you decline, you’ll incur a particularly egregious penalty of $5 per toll.

All-Inclusive Options

Some rental car companies offer an “all-inclusive” tolling service, but buyer beware. These programs often charge by the day regardless of whether you ever hit a toll road. We’ve seen customers get charged hundreds of dollars for these services where simply paying the tolls would have cost them less than $15. These all-inclusive services include PlatePass and e-Toll Unlimited.

4 Ways to Cheaper Rental Car Tolls

Close the transponder in the car.

If your rental car comes with an E-ZPass transponder and you don’t want to use it, try to close it. They are usually mounted in a lead-lined box that opens and closes. Closing the box hides it so the toll plaza can’t see it. Use a lane that accepts cash, and you can then pay cash for your toll.   If you’d rather be extra safe, you can get a Faraday bag which blocks devices from wireless signals. Here’s one we like.

Use cash toll lanes.

Be aware that this doesn’t work everywhere, as some toll roads are electronic-only, and driving through the reader will automatically trigger a bill to the rental company.

Use your own car’s toll transponder.

Bring it with you and then, when you pick up the rental car, either call the provider or log into your account online to add your rental car’s license plate. If you travel frequently, it might be worth ordering a second transponder on your account to keep in your travel bag.

Buy your own transponder.

Don’t already have a transponder? It’s pretty cheap and easy to get one, even if you don’t live in a state with toll roads. If you’ll be traveling in the Eastern US (Illinois to Florida to Maine) where tolls are handled by the E-ZPass consortium, we recommend ordering a transponder from Massachusetts—since there is no monthly fee and the cost of the transponder gets credited to your account and made available for tolls.

For the Southeastern US (North Carolina to Florida), E-ZPass will also work, depending on your route. Alternatively, we also recommend the E-PASS from the Central Florida Expressway Authority since it’s cheaper than the more popular SunPass. And for the central US (Kansas to Texas), a MyKTAG from Kansas is the best option. A portable hard-case transponder that works everywhere in Texas, Oklahoma and Kansas costs $25, or you can get the sticker version for free (they’re not meant to be portable, but we’ve had good luck just holding the sticker firmly against the windshield), and you aren’t required to prepay as long as you sign up with a valid credit card.

In summary, if you’re going to be traveling on toll roads, you can avoid surcharges if you pay cash at the toll booth (where possible) or bring your own transponder.
