Unless the federal government acts, Californians will no longer be allowed to travel in carpool High Occupancy Vehicle (HOV) lanes with a single occupant or receive reduced toll rates, even with a Clean Air Vehicle (CAV) decal. Drivers must follow posted vehicle occupancy requirements and if they violate the law they may receive a citation. The DMV stopped accepting applications for CAV decals on August 29. 

This program, in place for 25 years, is set to expire on September 30, 2025, under the current federal administration. As a result, starting October 1, 2025, EV drivers will be required to comply with standard HOV lane occupancy rules, potentially increasing traffic congestion and hindering California’s progress toward sustainable transportation.

Last year, my legislation, AB 2678, was passed with bipartisan support and signed into law by Governor Newsom. This bill would have extended the CAV program until January 1, 2027, contingent upon federal approval.

Regrettably, without federal authorization, this extension will not take effect.

There is still an opportunity to advocate for the continuation of this critical program. At the federal level, Representatives Mark DeSaulnier (CA-10) and Greg Stanton (AZ-04) introduced the HOV Lane Exemption Reauthorization Act on August 13, 2025. This legislation aims to extend the authorization for EVs and low-emission vehicles to use HOV lanes nationwide.

Your advocacy is essential to preserving this program and supporting California’s commitment to reducing emissions and promoting clean transportation.

I urge Californians to contact their U.S. Representative to express support for the HOV Lane Exemption Reauthorization Act. You can find your representative’s contact information below.
