What is FasTrak®?

FasTrak transponder

Your new FasTrak® transponder

With FasTrak® you bypass toll plazas - no slowing or stopping to pay. Here's how it works: when you open your prepaid FasTrak account, you'll be given a small electronic device that easily attaches to the inside of your windshield. And that's it! You're ready to use Fastrak!

When passing through a FasTrak toll zone, an overhead antenna reads the FasTrak transponder on your windshield, and the toll is automatically deducted from your prepaid account. No stopping, no fishing around in your car for change and no hassle! For even greater convenience, when your FasTrak account runs low, it is automatically replenished using the credit or debit card of your choice.

FasTrak is the perfect complement to the fun, scenic drive you will enjoy on the new South Bay Expressway. It's fast and easy - and who couldn't use an easier commute?
