For years, single-occupant electric vehicle (EV) drivers in California used the Clean Air Vehicle (CAV) decal program to bypass gridlock by using the High-Occupancy Vehicle (HOV) carpool lanes. However, the regulatory landscape has changed significantly. If you are shopping for a used EV or plug-in hybrid on CarListingHub.com, here is what you need to know.
The Sunset of the CAV Decal Program
The California Air Resources Board (CARB) and the DMV have officially brought the classic carpool sticker program to an end. Under federal highway funding guidelines, the CAV decal program officially expires, and all single-occupant carpool access privileges end.
Important Carpool Update: The final day to request a new decal was August 29, 2025, and all existing stickers—whether they are teal, burgundy, green, or yellow—lose their legal validity after September 30, 2025. Buying a used EV purely under the assumption that it grants you a free pass into the HOV lane during rush hour is no longer viable in California.
Navigating Express Lanes Moving Forward
Even though the sticker program has ended, pre-owned EV buyers can still access fast-moving lanes through regional toll networks like FasTrak.
Many metropolitan areas (such as the Bay Area, Los Angeles, and San Diego) have converted traditional HOV lanes into High-Occupancy Toll (HOT) "Express Lanes."
While you can no longer drive in these lanes for free as a single occupant using a bumper sticker, you can get discounted or clean-air transit pricing by configuring an Express Lane Transponder linked directly to an authorized clean energy account. Check with your regional transit authority (like Metro ExpressLanes or Bay Area FasTrak) for active EV discount programs.
