Metro ExpressLanes is making changes

Metro ExpressLanes is making changes to its Clean Air Vehicle Policy starting March 1, 2019:

Metro expresslane 2019 CAV stickers

Customers with a clean air vehicle (CAV) displaying a valid DMV-issued red or purple CAV decal

are eligible for a 15% discount off of the posted rate on the I-10 and I-110 Metro ExpressLanes. To qualify, eligible CAV decal holders must first register for the discount on our website at

All clean air vehicles must set the switch on their FasTrak transponder

to indicate the actual number of people in the vehicle for a given trip. CAVs are no longer allowed to use the 2 or 3+ transponder switch settings unless that many persons are present in the vehicle. Any CAVs incorrectly using the 2 or 3+ switch setting without that many occupants in the vehicle will be subject to CHP citation.

Other CAV vehicles (including those with yellow, green or white CAV decals)

will not be eligible to receive any CAV discounts.

As a reminder,

All vehicles traveling on the I-10 or I-110 Metro ExpressLanes must properly mount a FasTrak transponder. Carpoolers must have a FasTrak Flex (switchable) transponder that is used to indicate the number of occupants in the vehicle. Eligible carpoolers with a FasTrak Flex set to the proper position can continue using the Metro ExpressLanes toll-free.
