How to Pay California Highway 73 Tolls

California Highway 73 in Orange County charges tolls on all lanes between the San Diego Freeway (I-405) and the Costa Mesa Freeway (I-55). You have three ways to pay: set up an account with FasTrak, pay a toll invoice after you drive, or use a license plate account through the toll authority.

The fastest and cheapest option is FasTrak, which reads a small transponder mounted on your windshield and deducts the toll automatically. FasTrak users pay a lower rate than drivers who pay by invoice. If you don't have FasTrak and drive the toll road, the toll authority photographs your license plate and sends you an invoice by mail within 30 days.

You do not need to register your vehicle again or renew anything to use Highway 73. You only need to set up a payment method before or after your first trip. The toll amount varies by time of day and traffic conditions — rates are higher during peak hours and lower during off-peak times.

Key Takeaways

  • FasTrak is the cheapest way to pay Highway 73 tolls and requires a transponder mounted on your windshield that deducts tolls automatically.
  • If you don't have FasTrak, the toll authority will photograph your license plate and mail you an invoice within 30 days.
  • You can pay a toll invoice online, by phone, or by mail, and you have 30 days from the invoice date to pay without penalty.
  • Toll rates change by time of day and traffic conditions, so peak-hour tolls cost more than off-peak tolls on the same stretch of road.
  • Unpaid invoices result in late fees and can eventually lead to vehicle registration holds, so paying on time matters for your registration renewal.

Setting Up a FasTrak Account for Highway 73

To open a FasTrak account, visit the FasTrak website or call 1-888-FASTER1 (1-888-327-8371). You will need a valid email address, a phone number, and a payment method — credit card, debit card, or bank account. FasTrak will mail you a transponder, which usually arrives within 7 to 10 business days. You mount it on your windshield, and tolls are deducted automatically each time you drive Highway 73.

FasTrak accounts require a minimum balance, which varies but is typically $25 to $50. When your balance drops below a certain threshold, FasTrak automatically charges your payment method to refill it. You can check your balance and transaction history online at any time. If you sell your vehicle or no longer use Highway 73, you can close your account and request a refund of any remaining balance.

FasTrak rates on Highway 73 are lower than invoice rates. For example, during peak hours, a FasTrak toll might be $3.50 while an invoice toll for the same trip is $4.50. This discount applies every time you use the road with a valid transponder, so the savings add up quickly if you drive Highway 73 regularly.

Paying Highway 73 Toll Invoices by Mail or Online

If you drive Highway 73 without FasTrak, the toll authority will mail you an invoice. The invoice shows the date you drove, the toll amount, and your payment due date — typically 30 days from the invoice date. You can pay online through the toll authority's website, by phone at 1-888-FASTER1, or by mailing a check to the address on the invoice.

Online payment is the fastest method and confirms when ready. By phone, you will need your invoice number and a payment method ready. If you mail a check, allow at least 10 business days for it to arrive and be processed. Do not send cash by mail.

You can also set up a license plate account through the toll authority's website if you prefer not to use FasTrak. A license plate account lets you pay tolls after you drive without a transponder. You enter your vehicle information once, and the toll authority links future tolls to your account automatically. You will still receive invoices, but you can set up automatic payments so you don't have to remember to pay each one.

What Happens If You Don't Pay a Highway 73 Toll Invoice

If you don't pay within 30 days of the invoice date, a late fee is added to your bill. The late fee amount varies but typically ranges from $25 to $50 per unpaid toll. If you still don't pay after receiving a second notice, additional penalties accumulate and the toll authority may report the debt to a collection agency.

More importantly for vehicle registration: unpaid Highway 73 tolls can result in a registration hold. When you try to renew your vehicle registration with the California Department of Motor Vehicles, the DMV checks for outstanding toll debt. If you owe tolls, the DMV will not process your renewal until the debt is paid. This means your registration will expire and you cannot legally drive the vehicle.

If you have an unpaid toll invoice and a registration hold, contact the toll authority first to pay the debt. Once paid, the hold is usually lifted within one to two business days. Then you can proceed with your registration renewal through the DMV.

Toll Rates and Peak-Hour Pricing on Highway 73

Highway 73 uses congestion pricing, which means the toll amount changes based on traffic conditions and time of day. During peak commute hours — typically 6 a.m. to 10 a.m. and 3 p.m. to 7 p.m. on weekdays — tolls are highest. During off-peak hours and weekends, tolls are lower. The toll authority adjusts rates in real time to manage traffic flow.

The toll amount also depends on which segment of Highway 73 you drive. The road is divided into sections, and you pay based on how many sections you travel. A short trip might cost $1.50 to $2.00, while a longer trip could cost $4.00 to $5.00 or more during peak hours. You can check current toll rates on the FasTrak website before you drive.

FasTrak users always pay less than drivers who pay by invoice, regardless of the time of day. The discount is built into the FasTrak rate structure, so if you use Highway 73 more than a few times per month, FasTrak usually pays for itself.

Checking Your Highway 73 Toll Account and Payment History

If you have a FasTrak account, log in to the FasTrak website to view your balance, recent transactions, and account settings. You can also read statements for your records. The website shows the date, time, location, and amount of each toll you paid.

If you have a license plate account or received an invoice, you can check the status of your payment through the toll authority's website. Enter your invoice number or license plate to see whether your payment was received and processed. If you paid by mail and your payment hasn't appeared after 10 business days, contact the toll authority to confirm receipt.

Keep records of all toll payments, especially if you dispute a charge or need proof of payment for your records. Invoices and online receipts serve as documentation if there is ever a question about whether you paid.

Frequently Asked Questions

Do I have to use FasTrak on Highway 73?

No. You can drive Highway 73 without FasTrak and pay by invoice instead. However, FasTrak rates are lower, so if you use the road regularly, FasTrak saves money. You can also set up a license plate account to pay tolls after you drive without a transponder.

What if I get an invoice for a toll I didn't drive?

Contact the toll authority with your invoice number and explain the error. If your vehicle was stolen or someone else drove it, provide that information. The toll authority can investigate and remove the charge if it was incorrect. Keep documentation of any theft report or evidence that you didn't drive on that date.

Can I transfer my FasTrak transponder to a different vehicle?

Yes. Log into your FasTrak account online or call 1-888-FASTER1 to update your vehicle information. You can move the transponder to a new vehicle, but you must update your account first so tolls are charged correctly. If you have multiple vehicles, you can open separate FasTrak accounts or add multiple vehicles to one account.

Will unpaid Highway 73 tolls prevent me from registering a new vehicle?

Unpaid tolls on any vehicle in your name can create a registration hold at the DMV. The hold applies to your driver's license record, not just the vehicle that incurred the toll debt. Pay any outstanding tolls before you try to register a new vehicle to avoid delays.

How long does it take for a toll invoice to arrive in the mail?

Invoices typically arrive within 30 days of the date you drove. You have 30 days from the invoice date to pay without penalty. If you don't receive an invoice within 45 days of driving, contact the toll authority to confirm they have your correct mailing address.
