Ways to Pay

Toll Tag

With a FasTrak toll tag, tolls are deducted from your prepaid FasTrak account. FasTrak is the preferred choice for commuters and others who cross this bridge frequently. Carpools must have a toll tag to receive discounted tolls. Learn more about how to obtain a FasTrak toll tag.

License Plate Account

If you travel over Bay Area bridges regularly and do not want a prepaid toll tag, consider opening a License Plate Account. This type of account is now eligible to pay tolls at all Bay Area toll bridges. License Plate Accounts are not recommended for rental vehicle users. Learn more about opening a License Plate Account.

One-Time Payment

Another pay-as-you-go option is a one-time payment. You have 48 hours to pay a toll after crossing the bridge. Payments can be made online, over the phone or in person by contacting the Customer Service Center. This is a good choice for rental vehicle users. Learn more about opening a short-term one-time payment account.

Toll Invoice

If no account exists when a toll crossing is made, FasTrak will send an invoice to the vehicle's registered owner. No extra fees will be added to the toll invoice if it is paid within 21 days. Unpaid toll invoices will escalate to toll evasion notices with additional penalties and fees. Learn more about how to pay an invoice.

  • 2-axle vehicles, without a trailer, carrying 2 or more people

All carpool and other eligible vehicles must use designated carpool lanes and a FasTrak toll tag to receive discounted tolls.

Commute Bus or Vanpools

A commute bus or vanpool vehicle may cross toll free at any time in designated lane(s), in accordance with operational procedures. When passing through staffed lanes, vehicles will be charged an axle-based toll unless the driver presents a toll free commute bus ticket or uses a non-revenue FasTrak toll tag.
