FasTrak Pay by Plate reads your license plate instead of requiring a transponder

FasTrak Pay by Plate is a tolling method used on Bay Area bridges and roads where the toll authority photographs your vehicle's license plate and bills you by mail. You do not need to buy or install a transponder. The system automatically captures your plate when you drive through a toll plaza, matches it to your vehicle registration, and sends an invoice to the address on file with the California Department of Motor Vehicles.

The toll amount depends on the facility and the time of day. Some Bay Area bridges charge different rates during peak and off-peak hours. Pay by Plate is the default method if you do not have a FasTrak transponder account, but you can also set up a Pay by Plate account voluntarily to manage your tolls online and receive discounts.

Key Takeaways

  • Pay by Plate bills you by mail based on your license plate; no transponder purchase or installation is required.
  • Tolls are charged at the posted rate for the time of day you crossed, and invoices arrive within two to three weeks.
  • You can set up a voluntary Pay by Plate account online to view charges, set up autopay, and receive a small discount on some tolls.
  • If you do not pay within 30 days of the invoice date, late fees and penalties begin to accumulate, and the toll authority can report the debt to credit bureaus.
  • Unpaid tolls can prevent vehicle registration renewal and result in collection action by the toll authority or a third-party agency.

How the billing process works

When you drive through a toll plaza without a transponder, a camera photographs your license plate. The toll authority uses that image to look up your vehicle registration with the DMV and mails an invoice to the registered owner. The invoice includes the date, time, location, and amount of the toll, plus instructions for payment.

Payment is due within 30 days of the invoice date. You can pay by mail, phone, or online. If you set up a voluntary Pay by Plate account before crossing, you can view the charge online within one to two business days and pay when ready, which may avoid a mailed invoice altogether.

Voluntary Pay by Plate accounts and discounts

Creating a voluntary account on the FasTrak website lets you manage tolls online instead of waiting for paper invoices. You provide your license plate number, vehicle information, and billing address. Once the account is active, tolls post to your online dashboard within one to two business days of crossing.

Voluntary Pay by Plate accounts may receive a small discount on certain tolls compared to the default rate charged to drivers without accounts. The discount varies by facility and time of day. You can set up automatic payments so tolls are charged to your bank account or credit card each month, which also ensures you do not miss a due date.

What happens if you do not pay

If payment is not received within 30 days of the invoice date, a late fee is added to your account. The toll authority typically sends a second notice. If you still do not pay after 60 days, additional penalties and collection costs may be assessed. The total amount owed grows quickly.

After 90 days of non-payment, the toll authority can report the debt to credit reporting agencies, which will harm your credit score. The debt can also prevent you from renewing your vehicle registration with the DMV. Some toll authorities contract with collection agencies to pursue the debt, which may result in phone calls, letters, or legal action.

Unpaid tolls and vehicle registration

California law allows the toll authority to place a hold on your vehicle registration if tolls remain unpaid. When you try to renew your registration online or at the DMV, the system will flag the hold and deny renewal until the toll debt is resolved. This applies even if you owe tolls from years ago.

To clear the hold, you must pay the full amount owed, including any late fees and penalties. Once payment is received and processed, the hold is lifted and you can renew your registration. The process typically takes one to two weeks after payment is received.

Disputing a toll charge

If you believe a toll was charged in error — for example, if your plate was misread or you crossed at a time when you should have been charged a different rate — you can dispute the charge. Contact the toll authority directly by phone or through your online account and explain the issue. Provide any evidence you have, such as credit card statements showing you were elsewhere at the time.

The toll authority will review the photograph and your account history. If the dispute is valid, the charge may be removed or adjusted. If the toll has already been paid, you may receive a refund. Disputes must usually be filed within a set timeframe, often 30 to 60 days of the invoice date, so contact the toll authority promptly if you believe an error occurred.

Differences between Pay by Plate and FasTrak transponders

A FasTrak transponder is a small electronic device you mount on your windshield. It communicates with toll readers as you pass through, and tolls are deducted from a prepaid account balance. Transponder users typically receive a discount compared to Pay by Plate rates. You must maintain a minimum balance in your account to avoid service suspension.

Pay by Plate requires no upfront purchase or account setup — you are billed automatically by mail. However, you pay the full posted rate with no discount. Transponders are faster at toll plazas and do not rely on license plate recognition, which can occasionally misread plates. If you cross tolls frequently, a transponder usually costs less over time despite the initial purchase price.

Frequently Asked Questions

How long does it take to receive a Pay by Plate invoice?

Invoices typically arrive within two to three weeks of crossing the toll plaza. If you have set up a voluntary Pay by Plate account, you can view the charge online within one to two business days and pay when ready without waiting for mail.

Can I get a refund if I paid a toll by mistake?

Yes, if you can show that you crossed the toll plaza in error or that the charge was incorrect, you can request a refund. Contact the toll authority with details of the crossing and any supporting evidence. Refunds are processed after the dispute is reviewed and approved.

What happens if my license plate is unreadable or misread?

If your plate cannot be read clearly, the toll authority may send a notice asking you to provide your vehicle information. If the plate is misread and charged to the wrong vehicle, the registered owner of that vehicle can dispute the charge. Always dispute errors promptly to avoid late fees.

Do I need a Pay by Plate account, or will I be billed automatically?

You will be billed automatically by mail even without an account. Creating a voluntary account is optional but recommended because it lets you view charges online, pay when ready, and receive discounts on some tolls.

Can I switch from Pay by Plate to a FasTrak transponder?

Yes. You can purchase a transponder from the FasTrak website or customer service center and set up a prepaid account. Once your transponder is active, tolls will be deducted from your account balance instead of being billed by plate.
