Your Tesla can’t use the carpool lane solo anymore, and hasn’t been able to for a year.

If you’re still expecting a Clean Air Vehicle sticker to get your Tesla into the carpool lane alone, that perk is gone — and has been for over a year. California’s decal program ended for good on September 30, 2025, and solo EV drivers caught in HOV lanes since the grace period lapsed now risk a real ticket.

What actually changed

The Clean Air Vehicle decal program let qualifying electric and plug-in hybrid vehicles use carpool lanes regardless of how many people were in the car, plus reduced toll rates on HOT lanes. It ran under federal authority (23 U.S.C. § 166), and when that authorization lapsed, California’s DMV confirms the program ended at midnight on September 30, 2025 — state law couldn’t extend it on its own. The DMV had already stopped accepting new or replacement decal applications on August 29, 2025, so no sticker issued after that point was ever going to be valid for long. According to the Department of Energy’s Alternative Fuels Data Center, the decals had actually been expiring in phases by color for a couple of years before that — blue decals lapsed back in January 2025 — and September 30, 2025 was simply the last category still standing.

What it costs if you get caught

California Highway Patrol spent an initial grace period issuing warnings instead of citations. That grace period is over. A solo driver in a Tesla — or any EV — using a carpool lane without meeting the posted occupancy requirement now faces a citation reported at $490 in multiple California markets. Full toll rates on HOT lanes also kicked back in as of October 1, 2025, so the reduced-toll benefit is gone along with the carpool-lane access.

What’s actually left

Nothing replaces it as of this writing — there’s no new state program restoring solo HOV access for EVs, and nothing that’s been formally proposed targets Tesla specifically. If you commute on a route with carpool lanes, that means planning around actual occupancy requirements like everyone else, or using the general-purpose lanes. The decal’s toll discount is also gone, so if you were counting on reduced HOT-lane pricing as part of your commute cost math, rebudget for full rates.

This is separate from purchase incentives, which still vary by state — California’s own point-of-sale rebate programs for buying an EV are a different system from the carpool-lane decal and aren’t affected by this change.
