Indiana tolls are paid through the Indiana Toll Road, a 157-mile highway that runs east-west across the northern part of the state. You can pay tolls three ways: with a transponder account (the fastest method), by mail after receiving a toll notice, or at toll plazas if you have exact change. Most drivers choose a transponder because it costs less per toll and you never have to stop.

Key Takeaways

  • The Indiana Toll Road runs from the Ohio border near Fort Wayne to the Illinois border near Chicago, and tolls fund maintenance and operations of that highway only.
  • A transponder account (called an I-PASS or similar device) costs nothing to open and saves you money per toll compared to paying at a plaza or by invoice.
  • If you receive a toll notice in the mail, you have 30 days to pay before late fees are added to your bill.
  • You can set up automatic payments so your transponder account never runs empty, and you will receive a warning when your balance drops below a threshold you choose.
  • Rental cars and commercial vehicles have their own toll payment rules, so check with your rental company or carrier before driving the toll road.

How transponder accounts work and why they cost less

A transponder is a small electronic device that mounts on your windshield and communicates with toll collection equipment as you pass through a toll plaza. When you have an active transponder account, the toll is deducted automatically from your prepaid balance. The per-toll cost is lower than paying at a cash booth because the state processes fewer transactions and collects tolls faster.

To open a transponder account, you visit the Indiana Toll Road website or call their customer service line. You provide your vehicle information (license plate, vehicle type), a valid payment method (credit card, debit card, or bank account), and your contact information. The transponder device is mailed to you at no charge. Once you receive it, you mount it on your windshield inside your vehicle, and it is active when ready. You can add money to your account online, by phone, or by mail whenever you choose.

Most transponder accounts allow you to set up automatic replenishment. You choose a minimum balance—for example, $10—and when your account drops below that amount, a charge is automatically applied to your payment method to bring the balance back up to a level you set. This means you will not run out of funds mid-trip. You can also set email or text alerts so you know when a replenishment has occurred.

Paying tolls without a transponder

If you do not have a transponder, you can pay tolls at a toll plaza using cash, credit card, or debit card. The per-toll cost is higher than transponder rates. Some toll plazas have staffed lanes where you can hand cash or a card to an attendant; others have automated payment lanes where you insert cash or swipe a card yourself. Check the Indiana Toll Road website or signage at the plaza to see which payment methods are accepted at each location.

If you pass through a toll plaza without paying and your license plate is not registered with a transponder account, the toll road will send you an invoice by mail. The invoice includes the toll amount plus a processing fee. You have 30 days from the date on the invoice to pay. If you do not pay within 30 days, late fees are added, and the toll road may report the debt to a collection agency or suspend your vehicle registration renewal through the Indiana Bureau of Motor Vehicles.

Paying by invoice is the most expensive way to use the toll road because of the processing fee, so it is worth setting up a transponder account if you drive the toll road more than a few times per year.

What happens if you do not pay a toll invoice

When you receive a toll notice in the mail, the amount owed is tied to your vehicle's license plate. If you ignore the invoice and do not pay within 30 days, the toll road forwards the debt to a collection agency. The collection agency may contact you by phone, email, or mail to demand payment, and the debt may appear on your credit report.

More importantly, Indiana law allows the toll road to place a hold on your vehicle registration renewal. When your registration is due, you will not be able to renew it through the Indiana Bureau of Motor Vehicles until the toll debt is paid. This means you cannot legally drive the vehicle, and you risk a traffic stop and citation if you do. Paying the invoice as soon as you receive it is the simplest way to avoid this outcome.

If you believe you received an invoice in error—for example, because your transponder malfunctioned or you paid at the plaza but the system did not record it—contact the Indiana Toll Road customer service line with your receipt or transponder account details. They can investigate and remove the charge if they confirm payment was made.

Setting up and managing your transponder account online

Once your transponder account is open, you can manage it through the Indiana Toll Road website or mobile app. Log in with your account number and password to view your transaction history, check your current balance, add funds, update your payment method, and change your contact information. The transaction history shows every toll you have paid, the date, the location, and the amount deducted.

If your transponder device is damaged, lost, or stops working, you can request a replacement through your online account. A new device is mailed to you at no charge, and you can usually set up it when ready. If you sell your vehicle or no longer need the transponder, you can close your account online. Any remaining balance will be refunded to your original payment method within 7 to 10 business days.

The Indiana Toll Road also allows you to link multiple vehicles to one account if you own more than one car. Each vehicle gets its own transponder device, but all tolls are charged to the same account balance. This is useful if you drive different vehicles on different days but want to manage one payment account.

Tolls for rental cars and commercial vehicles

If you rent a car in Indiana and plan to drive the toll road, check with the rental company first. Some rental agencies include a transponder in the vehicle; others do not. If the rental car has a transponder, tolls are charged to the rental company's account, and you may see a separate charge on your rental bill. If the rental car does not have a transponder, you will receive a toll invoice by mail after your rental period ends, and you are responsible for paying it.

Commercial vehicles—trucks, buses, and vehicles over a certain weight—may have different toll rates than passenger cars. Some commercial vehicles are required to have a transponder, and rates vary by vehicle class. If you operate a commercial vehicle, contact the Indiana Toll Road commercial customer service line for information about your specific vehicle type and toll obligations.

Understanding toll rates and what your money funds

Toll rates on the Indiana Toll Road vary by vehicle type and distance traveled. A passenger car traveling the full length of the toll road (157 miles) costs less than a commercial truck traveling the same distance. Rates are set by the Indiana Toll Road authority and are reviewed periodically. Current rates are posted on the Indiana Toll Road website.

Tolls collected on the Indiana Toll Road are used to maintain and operate that highway only. They fund road repairs, snow removal, lighting, toll collection equipment, and staff salaries. Tolls do not fund other Indiana highways or roads. The toll road is a separate entity from the Indiana Department of Transportation, though both are state agencies.

Frequently Asked Questions

Can I use my transponder in other states?

The Indiana Toll Road transponder works only on the Indiana Toll Road. If you travel to other states with toll roads, you will need to pay tolls through that state's system or obtain a separate transponder. Some states participate in reciprocal programs that allow certain transponders to work across state lines, but Indiana's system is not currently part of those programs.

What if my transponder does not work at a toll plaza?

If your transponder fails to read at a toll plaza, drive to the cash lane and pay the toll manually. Then contact the Indiana Toll Road customer service line with the date, time, and location where the device failed. They can investigate whether the device is malfunctioning and may credit your account if the transponder was at fault.

How long does it take to receive a transponder in the mail?

Transponder devices are typically mailed within 5 to 7 business days of account creation. Delivery time depends on your location and the postal service. You can use your account number to pay tolls at a cash plaza while you wait for the physical device to arrive.

Can I transfer my transponder balance to another person?

No. Transponder accounts are tied to the account holder's name and payment method. If you want to give someone else access to tolls, they need to open their own account. You cannot transfer funds between accounts.

What happens if I move out of Indiana?

You can keep your transponder account open even if you move away, as long as you maintain a valid payment method on file. If you no longer plan to use the toll road, you can close your account online and request a refund of any remaining balance.
