The program encouraged EV adoption but will end on September 30, 2025
- California’s EV HOV access ends September 30 with the loss of an EPA waiver.
- Similar programs in other states will also expire, impacting clean-energy drivers.
- California’s bid to extend the program to 2027 is stalled without federal approval.
For years, driving solo in an electric or alternative fuel vehicle often came with a quiet perk: a pass into the fast-moving HOV lane. That benefit, long seen as an incentive to support cleaner transportation, is now nearing its end. California’s Clean Air Vehicle (CAV) Decal program, once a reliable shortcut for qualifying drivers, is scheduled to wind down on September 30, 2025. And the impact won’t stop at the state line.

The program exists in various forms across several states, including Maryland, Hawaii, North Carolina, and others. The system encouraged EV and alternative fuel adoption but gave drivers access to HOV lanes without meeting minimum occupancy requirements. Its continuation has always depended on an Environmental Protection Agency waiver. That same waiver is now facing a legal challenge from the Republican-led Congress.
Federal Friction
“Clean Air Vehicle Decals are a smart, cost-effective incentive that has played an important role driving the adoption of clean and zero-emission vehicles in California,” Liane Randolph, chair of the California Air Resources Board, told Road&Track. “But thanks to the federal government’s failure to act, this successful program is coming to an end.”
As of now, the program ends on September 30. After that, every vehicle in the HOV lane across the nation will need to meet minimum occupancy rules or pay a toll to gain access, regardless of propulsion type. In California alone, that’ll affect 519,000 people who have active decals for the HOV lane.
Nationwide Shift
The change won’t stop in California. According to the Department of Motor Vehicles, “Putting the brakes on this program means that starting October 1, 2025, CAV decals will no longer be valid in California, or elsewhere in the United States. All vehicles will be required to meet posted vehicle occupancy to travel in carpool lanes and pay required tolls or risk receiving a citation.”
Notably, Sacramento is trying to extend the program. State Assemblymember Greg Wallis (R-Bermuda Dunes) secured a bill to push the end date to January 1, 2027, signed by Governor Gavin Newsom last year. But without federal approval, that plan is dead on arrival.
Unless there’s some big surprise coming in the next month or two, HOV lanes across the USA are about to go back to being carpool lanes.
