The 60-day grace period is over, and California Highway Patrol officers are ready to write tickets.

We’ve been tracking the systematic rollback of EV incentives for months, and Monday marks another painful milestone. Starting December 1, 2025, California’s 500,000-plus electric vehicle owners who enjoyed solo access to carpool lanes will face $490 minimum fines if they continue using HOV lanes without passengers, reports the SF Chronicle.

1999	California launches Clean Air Vehicle decal program
September 30, 2025	Federal authorization expires, $7,500 EV tax credit ends
October 1, 2025	60-day grace period begins
December 1, 2025	CHP enforcement begins, $490 fines

The Clean Air Vehicle decal program, which launched in 1999 and issued over one million stickers during its 26-year run, officially ended on September 30 after Congress declined to extend federal authorization. CHP gave drivers a 60-day grace period to adjust their habits. That grace period expires at midnight tonight.

“On Dec. 1, we will start conducting enforcement on this particular violation,” said Officer Adib Zeid, a CHP spokesperson. “It will be fair play.”

What EV Drivers Need to Know

The rules are straightforward but unforgiving. Solo EV drivers caught in carpool lanes during restricted hours now face the same treatment as any other HOV violator.

“Starting Monday it will be an enforceable violation,” said CHP Sgt. Andrew Barclay. “Officers have discretion on every stop they make. But the important thing to remember at this point is that you can now be cited for a violation of HOV lane rules even if you have the sticker.”

That colorful decal on your bumper? It’s now a souvenir of a bygone era. You can leave it on or peel it off, but it won’t save you from a ticket.

Most California freeways require two occupants for HOV access. Some stretches, like Interstate 80 in the East Bay, require three. The fine starts at $490 and can climb higher with additional fees.

The Double Whammy: Tax Credits Gone, Carpool Access Gone

The timing couldn’t be worse for EV owners. Exactly 60 days before carpool enforcement began, the $7,500 federal EV tax credit expired on September 30, 2025. Congress terminated both the new vehicle credit and the $4,000 used EV credit through President Trump’s “Big Beautiful Bill.”

California EV owners are now paying full price for vehicles that cost thousands more than they did six months ago, while simultaneously losing the daily commute benefit that made ownership worthwhile for many.

John Stringer, president of Tesla Owners of Silicon Valley, a club with 6,000 members, captured the frustration.

“It’s a huge, huge bummer for EV enthusiasts,” Stringer said. “It has been one of the things we’ve been able to enjoy for years. It was one of the reasons why I bought my first EV.”

Stringer, who commutes from San Jose to San Mateo, said carpool access cut 20 minutes each way off his 75-minute drive. Starting Monday, that time savings disappears.

Why Congress Let the Program Die

The Clean Air Vehicle decal program required federal authorization under Section 166 of Title 23 of the United States Code. California lawmakers passed legislation extending the program through January 2027, but that state law meant nothing without federal approval.

Congress had multiple opportunities to extend authorization. They declined.

The California Air Resources Board expressed disappointment but acknowledged the state’s hands were tied.

“The state needs approval to operate the program on federal roadways throughout the state,” said Lindsay Buckley, CARB’s director of communications. “We’re really disappointed in the federal government’s inaction.”

California was one of 13 states offering similar programs. Arizona, Colorado, Florida, Georgia, Hawaii, Maryland, New Jersey, New York, North Carolina, Tennessee, Utah, and Virginia all saw their programs end on September 30.

Traffic Impact Remains Uncertain

Nobody knows exactly what happens when 500,000 vehicles merge from HOV lanes into general traffic.

John Goodwin, spokesperson for the Metropolitan Transportation Commission, noted the timing provides some buffer.

“These stickers officially lost their value in the middle of a holiday season, when traffic is fairly depressed,” Goodwin said. It typically remains stagnant “until Martin Luther King Day in the middle of January.”

The real test comes when normal commute patterns resume in 2026.

Highway 101 between Novato and Sonoma County is particularly concerning. Drivers already see near-empty carpool lanes next to bumper-to-bumper general traffic. Forcing more vehicles into already-packed lanes could worsen that disparity.

Some EV owners are exploring alternatives. The Bay Area’s “casual carpool” program, where drivers pick up strangers at designated spots to meet occupancy requirements, is making a comeback. Others are considering public transit or adjusted work schedules.

The Math Has Changed

For many California EV buyers, the calculation that justified their purchase just fell apart.

A 2016 UCLA Luskin Center study found that 40% of plug-in vehicle buyers made their purchase specifically to get the carpool sticker. It was the number one reason listed.

Alan Cohen, a Berkeley Tesla owner, waited for his car to charge at El Cerrito Plaza last week, frustrated about losing his shortcut to the Bay Bridge.

“I would think that they would want to support electric vehicles,” Cohen said.

He’s grudgingly accepted the new rules, as has Ken Hinh, another Tesla owner whose sticker expired last year. Neither plans to risk the $490 fine by sneaking into carpool lanes.

“It’s definitely affected my commute,” Hinh said. He now pays for express lanes on Highway 101.

EVXL’s Take

This is the predictable conclusion of a policy trajectory we’ve been documenting since May 2025.

When Senate Republicans first pushed to end the $7,500 EV tax credit, we warned the industry was heading for a cliff. When Trump’s “Big Beautiful Bill” passed in July, we explained exactly what would happen: a brief surge as buyers rushed to beat the deadline, followed by a devastating collapse.

October proved us right. EV sales cratered 24% in a single month after the tax credit expired. Within weeks, GM announced 3,300 layoffs and idled $2 billion in battery plants. Ford stopped F-150 Lightning production with no restart timeline.

Now California EV owners face another indignity. The state that leads the nation in EV adoption, where one in four new vehicles sold is electric, just lost another tool for encouraging that adoption.

The systematic dismantling of EV incentives reveals an uncomfortable truth we’ve covered extensively: American EV adoption remains heavily dependent on government support. When you remove that support, the market responds immediately.

This stands in stark contrast to China, where manufacturers achieved genuine cost advantages through integrated supply chains and manufacturing efficiency. Two-thirds of EVs sold in China in 2024 were priced lower than their gasoline equivalents, even without subsidies.

The carpool lane program served its original purpose. When Governor Gray Davis signed AB 71 in 1999, less than 2% of California cars were electric. Last year, 25.3% of new vehicles sold in the state were zero-emission. The Tesla Model Y has been California’s top-selling car for three consecutive years.

Mission accomplished, in a sense. EVs no longer need training wheels.

But the abrupt termination, combined with the tax credit expiration, sends a clear message: the era of EV exceptionalism in America is over. From here on out, electric vehicles compete on price and merit alone.

For California’s half-million affected drivers, Monday morning’s commute just got a lot longer.
