Frequently Asked Questions

FasTrak Transponder

Why is a transponder required on 405 Express Lanes?

The 405 Express Lanes operates with a state-of-the-art electronic toll collection system which requires a FasTrak® transponder. This transponder-based system allows travel without stopping to pay a toll and there will be no cash payments or toll booths. FasTrak® transponders will be required for customers to use the express lanes.

To use the 405 Express Lanes, vehicles must have a properly mounted FasTrak® transponder associated with an account.

In order to receive carpool discounts on the 405 Express Lanes, vehicles must have a FasTrak® Flex switchable transponder.

Travelling without a transponder on the 405 Express Lanes is a violation of the California Vehicle Code and may result in the issuance of a toll evasion violation notice or citation by the California Highway Patrol.
