New Clean Air Vehicle policy for ExpressLanes begins Friday

This is a friendly reminder that Metro ExpressLanes is making changes to its Clean Air Vehicle Policy starting Friday, March 1:

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 Flex transponder to indicate the number of people in the vehicle for any 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. Clean Air Vehicles with incorrect switch settings may be subject to CHP enforcement. As a courtesy to our customers and to allow additional time for eligible CAVs to register, CHP will not be issuing citations regarding this policy during the month of March.

Additionally, per recent Metro Board direction, we are extending the enforcement grace period to May 31, 2019 during which time CHP may provide warnings regarding this policy. CHP will issue citations related to CAVs beginning in June 2019.

Other CAV vehicles (including those with yellow, green or white CAV decals) will not be eligible to receive any CAV discounts.

  1. So when is Metro going to do away with monthly “account maintenance” fees. Stop the waiving of them and get rid of them. My usage of the 110 corridor is such that I might pay occasionally, but often I have a passenger. But I may go a month or more with no trips. Also, I have had to suffer in I-10 eastbound mainline traffic on a Friday afternoon, even though I had 4 or 5 people in the car.

  2. Am I the only one who thinks clean air vehicles should be in regular lanes like the rest of us? I was hoping the law which allowed them in carpool lanes etc would expire one of these days.
