California toll roads let you pay online through FasTrak or individual toll agency websites, depending on which road you used

California operates toll roads through multiple agencies, each with its own payment system. The most common option is FasTrak, a statewide transponder program that works on most Bay Area bridges, Los Angeles County roads, and San Diego County toll facilities. If you don't have a FasTrak account, you can pay individual tolls through the toll agency's website or by mail. The method depends on which road you drove and whether you have a transponder.

Paying online is faster than waiting for a bill in the mail, and some agencies charge a processing fee if you pay after the toll date. Understanding which agency operates your road and which payment method works for that road saves you time and money.

Key Takeaways

  • FasTrak is the main transponder program for California tolls and works across most toll roads in the state, but you must set up an account and load money into it before or after driving.
  • If you don't have FasTrak, you can pay tolls online through the individual toll agency website within a set window (usually 5 to 30 days after driving), or by mail.
  • Late payments often trigger a higher fee or violation notice, so paying within the agency's important date is cheaper than waiting.
  • Each toll road is operated by a different agency — Bay Area Toll Authority, Los Angeles County Metropolitan Transportation Authority, or San Diego Association of Governments — and each has its own payment portal.

FasTrak: The statewide transponder option

FasTrak is a prepaid transponder system that lets you drive through toll plazas without stopping. You buy a transponder (a small electronic device), attach it to your windshield, and load money into your account. When you drive through a toll plaza, the transponder is read automatically 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.

To open a FasTrak account, visit the FasTrak website (www.bayareafastrak.org for Bay Area; www.metro.net for Los Angeles County; www.sandag.org for San Diego County) or call the customer service number for your region. You will need a valid driver's license, vehicle registration, and a payment method (debit or credit card). The transponder itself costs between $25 and $35 depending on the agency, and that cost is credited toward your first toll charges.

FasTrak works on all Bay Area toll bridges, the 91 Express Lanes in Orange County, the 110 and 10 Express Lanes in Los Angeles, the I-15 Express Lanes in San Diego, and several other regional toll roads. If you drive on multiple toll roads in different counties, you may need separate accounts for each region, though some agencies allow you to manage multiple transponders under one login.

Paying tolls online without a transponder

If you drove a toll road without a FasTrak transponder, the toll agency will send you a notice with payment instructions. You have a window of time — usually 5 to 30 days depending on the agency — to pay online before a late fee is added. The notice will include a transaction number and a link to the toll agency's payment portal.

To pay online, go to the toll agency website for the road you used, enter your transaction number (or license plate number), and follow the payment steps. You can pay with a debit card, credit card, or electronic check. Most agencies process online payments within one business day. If you miss the important date, the agency will typically add a violation fee (ranging from $25 to $70 depending on the agency) and may send a second notice.

The three main toll agencies in California are the Bay Area Toll Authority (operates bridges in the San Francisco Bay Area), Los Angeles County Metropolitan Transportation Authority (operates the 91, 110, and 10 Express Lanes), and the San Diego Association of Governments (operates the I-15 Express Lanes). Each has its own website and payment portal, so you need to know which road you used to find the right agency.

Which toll road you used and how to find the right payment portal

California toll roads are not all operated by the same agency, so the first step is identifying which road you drove. The major toll roads are the Golden Gate Bridge, Bay Bridge, and other Bay Area bridges (Bay Area Toll Authority); the 91 Express Lanes in Orange County (Orange County Transportation Authority); the 110 and 10 Express Lanes in Los Angeles (Los Angeles County Metropolitan Transportation Authority); and the I-15 Express Lanes in San Diego (San Diego Association of Governments).

If you received a toll notice in the mail, it will show the agency name and the road name. If you did not receive a notice yet but know which road you used, search "[road name] toll payment" or "[agency name] pay toll online" to find the correct portal. Each agency's website has a "Pay a Toll" or "Pay Now" button that lets you enter your license plate or transaction number and make a payment.

Some toll roads, like the Golden Gate Bridge, have their own dedicated payment systems separate from FasTrak. The Golden Gate Bridge website (goldengate.org) has its own toll payment portal. If you are unsure which agency operates a specific road, call 511 (California's transportation information line) and provide the road name and the date you drove it.

Late payments and violation fees

Paying a toll after the agency's important date triggers a violation fee on top of the original toll amount. The fee varies by agency but typically ranges from $25 to $70 for a first violation. If you receive a second notice and still do not pay, the fee may increase further, and the agency can report the violation to the California Department of Motor Vehicles, which may affect your vehicle registration renewal.

To avoid violation fees, pay within the timeframe shown on your toll notice. If you cannot pay by the important date, contact the toll agency's customer service line — many agencies offer payment plans or fee waivers in cases of financial hardship or if you can show the notice was sent to the wrong address. Paying online is usually faster than paying by mail, so the online option reduces the risk of missing the important date.

If you dispute a toll charge (for example, if you believe you were not the driver or the toll was charged twice), contact the toll agency directly with your transaction number and an explanation. Most agencies have a dispute process that takes 30 to 60 days to resolve.

Setting up automatic payments with FasTrak

Once you have a FasTrak account, you can set up automatic replenishment so you never run out of balance. Log into your FasTrak account online, go to the "Account Settings" or "Payment Methods" section, and enable automatic replenishment. You choose the amount (usually $25 to $100) and the balance threshold at which the account refills. For example, you can set it to add $50 to your account whenever the balance drops below $10.

Automatic replenishment is optional but recommended if you use toll roads regularly. Without it, your account balance can drop to zero, and you will receive a toll notice in the mail instead of being charged automatically. Setting up automatic payments also helps you avoid late fees because your account will always have enough balance to cover tolls.

Paying tolls by mail if you cannot pay online

If you do not have internet access or prefer to pay by mail, you can send a check or money order to the toll agency. The toll notice you receive in the mail will include a mailing address and instructions. Write your transaction number on the check and mail it to the address provided. Payment by mail takes longer to process — typically 10 to 15 business days — so mail your payment well before the important date to avoid a late fee.

Some toll agencies also accept payment by phone. Call the customer service number on your toll notice to pay with a debit or credit card over the phone. Phone payments are processed the same day and are a good option if you are close to the important date and do not want to risk mail delays.

Frequently Asked Questions

What if I never received a toll notice in the mail?

The toll agency may have sent the notice to the wrong address if your vehicle registration address is outdated. Contact the toll agency with your license plate number and ask them to resend the notice. You can also check the agency's website and enter your license plate to see if there is an outstanding toll balance.

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

Yes. Contact the toll agency with your transaction number and explain the duplicate charge. Most agencies process refunds within 30 to 60 days if you can provide proof of both charges. Keep your receipt or confirmation email from your online payment as evidence.

Do I need a separate FasTrak account for each toll road?

It depends on the region. Bay Area FasTrak works across all Bay Area bridges and some regional roads. Los Angeles and San Diego have separate systems. If you drive tolls in multiple counties, you may need multiple accounts, but some agencies allow you to link them under one customer profile.

What happens if I ignore a toll notice?

Ignoring a toll notice results in escalating fees and eventually a report to the California Department of Motor Vehicles, which can block your vehicle registration renewal. The agency can also pursue collection action. Paying the toll and any accrued fees is always cheaper than letting it go to collections.

Can I pay someone else's toll if I borrowed their car?

Yes. If you drove someone else's vehicle through a toll plaza, you can pay the toll online using the vehicle's license plate number. The toll notice will be sent to the registered owner, but you can contact the toll agency and ask to pay on their behalf, or the owner can pay and you can reimburse them.
