About Transponders
The 405 Express Lanes operates with a state-of-the-art electronic toll collection system which requires a FasTrak® transponder.
The transponder-based system allows travel without stopping to pay a toll at a toll booth. FasTrak® transponders are required for customers to use the express lanes.
Transponders
The 405 Express Lanes offers three types of transponders. Based on your vehicle type, either an interior- or exterior-mounted FasTrak® sticker transponder will be provided with your account at no charge. Take advantage of carpool discounts, a switchable transponder is required and can be purchased through the 405 Express Lanes for $15.
If you have an existing transponder and an active account from any toll agency in California, you can use your FasTrak® transponder on any toll road in California.
