How SR-73 tolls work and where to pay them

State Route 73 (SR-73) is a toll road in Orange County that runs from San Diego to Costa Mesa. When you drive it, you owe a toll that varies by time of day and traffic conditions — the toll is higher during peak commute hours and lower during off-peak times. You do not pay at a booth; instead, the toll is collected electronically by reading your license plate or a transponder mounted on your windshield.

The toll road is operated by the Orange County Transportation Authority (OCTA). You have three ways to pay: set up an account with a FasTrak transponder, pay by mail after receiving an invoice, or use the Pay-by-Plate system, which charges your credit card or bank account based on your license plate. Most drivers choose FasTrak because it offers a small discount and avoids the hassle of invoices.

Key Takeaways

  • SR-73 tolls are collected electronically by license plate or transponder, not at a toll booth, and the amount changes throughout the day based on traffic.
  • FasTrak is the most common payment method and gives you a discount compared to paying by mail or Pay-by-Plate.
  • You can set up a FasTrak account online at the OCTA website or by phone, and the transponder arrives in the mail within one to two weeks.
  • If you do not have an account, you will receive a toll invoice by mail within 30 days, and you must pay it within 30 days of the invoice date to avoid late fees.
  • Pay-by-Plate lets you pay tolls without a transponder by linking your license plate to a payment method, though it costs slightly more than FasTrak.

Setting up a FasTrak account for SR-73

To open a FasTrak account, visit the OCTA website (octa.net) or call 1-888-OCTA-411. You will need a valid driver's license or ID, a vehicle license plate number, and a payment method — either a credit card or bank account. The process takes about 10 minutes online.

Once you submit your process, OCTA mails you a FasTrak transponder, which usually arrives within one to two weeks. You mount it on your windshield behind the rearview mirror, following the instructions that come with it. The transponder is read automatically as you pass through the toll zone, and the toll is deducted from your account balance. You can set up automatic replenishment so your account refills when the balance drops below a certain amount, or you can add money manually whenever you want.

FasTrak accounts are specific to SR-73 and do not work on other California toll roads. If you also drive the 91 Express Lanes or the San Diego-Coronado Bridge, you would need separate accounts for those.

What happens if you do not have an account

If you drive SR-73 without a FasTrak transponder or Pay-by-Plate account, OCTA reads your license plate and sends you a toll invoice by mail. The invoice arrives within 30 days of your drive and shows the toll amount, the date you drove, and the due date. You have 30 days from the invoice date to pay.

Payment by mail costs more than FasTrak — you pay the full toll amount with no discount. If you do not pay within 30 days, OCTA charges a late fee (the amount varies but typically starts at $25 to $50). If you continue not to pay, the debt can be referred to a collection agency, and it may affect your credit report. OCTA can also place a hold on your vehicle registration renewal until the toll and fees are paid.

If you receive an invoice and plan to use SR-73 regularly, opening a FasTrak account afterward will not erase the invoice — you still owe that toll. However, future tolls will be charged at the FasTrak rate once your account is active.

Using Pay-by-Plate if you do not want a transponder

Pay-by-Plate is an alternative to FasTrak if you do not want to install a transponder or wait for one to arrive. You link your license plate to a credit card or bank account on the OCTA website, and tolls are charged automatically each time you drive SR-73. The toll amount is the same as what you would pay by invoice — higher than the FasTrak rate — but you avoid late fees because the payment is automatic.

To set up Pay-by-Plate, go to octa.net, enter your license plate number, and provide your payment method. The account is active when ready, so you can drive right away. If you later want to switch to FasTrak to get the discount, you can open a FasTrak account and your Pay-by-Plate account will close automatically once the transponder is activated.

Understanding SR-73 toll rates and peak hours

SR-73 tolls change throughout the 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 times and weekends, tolls are lower. The exact toll amount depends on your vehicle type (motorcycle, car, or truck) and the specific segment of SR-73 you drive, since the road is divided into zones.

FasTrak users pay a discounted rate compared to Pay-by-Plate or invoice payers. For example, a FasTrak toll might be $1.50 during off-peak hours, while the same trip by invoice could cost $2.50 or more. The discount incentivizes drivers to set up accounts and helps OCTA manage traffic flow because it encourages people to drive during off-peak times when tolls are cheaper.

You can see current toll rates on the OCTA website before you drive, though rates are adjusted periodically. If you have a FasTrak account, you can also check your account balance and recent toll charges online or through the OCTA mobile app.

Disputing a toll charge or fixing account errors

If you believe you were charged incorrectly or drove SR-73 but did not receive an invoice, contact OCTA directly. You can dispute a charge online through your FasTrak account, by phone at 1-888-OCTA-411, or by mail. OCTA asks that you provide the date you drove, your vehicle information, and an explanation of the issue.

Common disputes include being charged twice for the same trip, being charged for a trip you did not make, or a transponder malfunction. OCTA investigates these claims and typically responds within 30 days. If the dispute is found in your favor, OCTA refunds the toll and any associated fees.

If your transponder stops working, you can request a replacement through your FasTrak account or by calling OCTA. Replacements are usually free if the device is defective, though OCTA may charge a fee if the damage is your fault.

Frequently Asked Questions

Can I use my FasTrak transponder from another toll road on SR-73?

No. FasTrak transponders are specific to each toll road in California. A transponder from the 91 Express Lanes or the Bay Area will not work on SR-73. You must open a separate FasTrak account for SR-73 and receive a new transponder.

What if I sell my car or the transponder falls off?

If you sell your vehicle, contact OCTA and remove the license plate from your FasTrak account so tolls are not charged to you. If your transponder falls off or is damaged, request a replacement through your account or by phone. Until the replacement arrives, tolls will be charged by license plate and you will receive an invoice.

Do I have to pay SR-73 tolls if I am a resident of Orange County?

Yes. All drivers pay tolls on SR-73 regardless of where they live. There is no resident discount or exemption, though some vehicles (such as certain emergency vehicles) may be exempt. Check the OCTA website to see if your vehicle type qualifies.

How long do I have to pay a toll invoice before it goes to collections?

You have 30 days from the invoice date to pay. If you do not pay within that window, late fees are added and the debt may be referred to a collection agency. OCTA can also place a hold on your vehicle registration renewal.

Can I get a refund if I overpaid my FasTrak account?

Yes. If your account balance is positive and you no longer plan to use SR-73, you can request a refund through your FasTrak account or by contacting OCTA. Refunds are typically processed within 30 days.
