MileCheckShould you get the rental car’s toll pass?
Published · Updated
Buy the rental toll plan when its convenience is worth the added charge for your route. First check whether your own transponder is accepted. Declining at the counter does not necessarily stop an unpaid toll from entering the rental company’s billing program.
Facts checked September 2026. Every number links to its source; prices and rules change, so confirm the day you travel.
Find the payment method before driving
Check each toll road’s operator, not just the state. SunPass explains how Florida rental tolls can go through rental-company programs. A plate photographed on a cashless road does not mean you personally receive the bill.
Do not assume a generic plate-pay account prevents rental fees. Confirm that the road operator accepts rental vehicles and how to register yours.

Flat-rate or inclusive plans are different products. Ask which one appears on your agreement.

Two toll days do not mean two tolls
Under the cited Avis standard terms, using toll roads on two separate days adds $13.90 in convenience fees, before tolls. Six toll-use days reach the $34.95 cap. Several tolls on one day do not create several daily convenience fees.
That calculation uses the published fee. It is not a quote for the road tolls on your trip.
Using your own transponder
SunPass permits use of a personal transponder in a rental vehicle with the account steps it specifies. Follow its instructions for the rental plate and start and end dates.
Check compatibility with every road on your route. A transponder working at home does not establish coverage elsewhere.

Washington: Good To Go!
Washington’s toll roads are run by WSDOT under the Good To Go! name. WSDOT lists the SR 520 Bridge, the SR 99 tunnel, the Tacoma Narrows Bridge, the SR 509 Expressway, and the I-405 and SR 167 express toll lanes.
WSDOT says to check your rental contract’s terms before using a toll road. It also says every rental agency has different policies and some add fees WSDOT does not control.
You can use a temporary Good To Go! account without buying a pass. WSDOT says that saves $1.75 on every toll compared to paying by mail, which costs $2 more per toll than an account. Without a pass there is a 25-cent fee per trip, and you cannot carpool free in the I-405 or SR 167 express toll lanes.
Other toll systems, in their own words
| Where | What the operator says |
|---|---|
| San Francisco, Golden Gate Bridge | Tolls are charged southbound only, into San Francisco. A renter can use the rental company’s program or opt out and pay directly, up to 30 days before crossing or within 48 hours after. The bridge says most rental agencies charge convenience fees. |
| Illinois Tollway | Short-term rental vehicles can be added to an I-PASS account online or in the Tollway app. Put the rental’s plate on the account before you drive. A vehicle that is not on the account can get an invoice with added fees. |
| Maine Turnpike, E-ZPass | If your own tag is not properly mounted, the plate image may be charged to the rental company, even if you listed the plate on your account. |
| Austin area, Central Texas Mobility Authority roads | Renters are required to pay and should contact the rental agency about payment. Rental company programs vary by agency and add fees beyond the toll. |
These are four operators, not a full list. For any other toll road, read that operator’s own rental page before you drive.
A transponder is already in the car
Ask the branch how to disable or shield its device before using your own. Do not remove rental equipment. Keep the rental agreement and toll receipts until the charges settle.
Avis describes ways to avoid its standard service, including paying tolls through permitted alternatives. Simply leaving a cashless toll unpaid is not one of them.

Questions, answered
Does saying no at the counter prevent every fee?
No. An unpaid toll can still enter the company’s billing program.
Is the daily fee the toll itself?
Not under the standard Avis and Enterprise programs described here. Tolls are additional.
Does every rental company charge on unused days?
No. Read whether your plan charges per toll-use day or for the whole rental.
Can you bring your own SunPass?
Yes, subject to SunPass’s rental-vehicle instructions and road compatibility.
Should you remove the rental transponder?
No. Ask the branch how to shield or disable it correctly.
What if the invoice includes the wrong dates?
Compare it with your rental agreement and receipts, then dispute the specific charge with the billing provider.
