FasTrak is easy to use. Simply add money to your FasTrak account and, each time you use your toll tag, the toll amount is automatically deducted from your prepaid balance.
You can pre-load money onto your FasTrak account online, by phone, in person or by mail.
Visit the Bay Area FasTrak website for details.
Maintaining a FasTrak account is free. When you close your account and return your tag, the remaining prepaid balance will be returned to you.
