FasTrak is an electronic toll tag that works throughout the California toll facilities. Just stick the device on your windshield and zoom through any of the toll roads, toll bridges, express lanes, or park at San Francisco International Airport (SFO) parking garages. It will automatically deduct the toll from the linked account. You also get access to dedicated toll lanes and toll discounts for carpools, CAVs and EVs.

As a toll penalty can be multiple times the actual toll cost in California, it is worth it to get a FasTrak to drive around here.

FasTrak is accepted in California as three accounts type FasTrak Prepaid, FasTrak Charge and FasTrak Invoice

Use FasTrak Toll Calculator to calculate tolls for travelling across California with a FasTrak.

FasTrak Charge- FasTrak Charge allows payment for individually charged tolls and is free to set up. You can make payments via credit card, cash or check. This, too, is valid across all the California toll facilities. FasTrak Charge does not include discounted toll fee features.

FasTrak Invoice - If you cross a FasTrak toll without a valid FasTrak transponder, you will receive a toll violation notice from FasTrak called FasTrak Invoice. The invoice fee is $2. You can pay it online, over the phone, by mail, or by using a Cash Payment Location[2].
