FasTrak Transponder

Where can I use my transponder?

You can use your 405 Express Lanes FasTrak® transponder on any toll facility in California. The 405 Express Lanes exchanges information with the other toll operators within the state to provide you with seamless travel with a single account. If you wish to receive a carpool discount on an Express Lane other than the 405 Express Lanes, you will need a FasTrak® Flex® switchable transponder.
