Jay Leno built one of the most famous car collections in America and California just told him to park it.
Now he's taking the fight to Sacramento – and he's not alone this time.
What California's green lobby has waiting for him at the end of August could end it for good.
Leno's Law Would End California's Classic Car Smog Check Nightmare
California law requires every gas-powered vehicle to pass a smog check every two years to keep its registration.
Modern cars breeze through it in an afternoon.
A 1979 Trans Am is a bureaucratic death sentence.
Smog testing stations across the state increasingly lack the equipment to inspect vehicles built before the early 1980s.
That means cars that have been street-legal for decades are now effectively banned – not because the law changed, but because the bureaucracy broke.
"You have an old car, it's been legal your whole life, and now it's illegal because you can't find a station to do the emissions test," Leno told lawmakers. "And then now you're just making criminals out of people that want to do the right thing."
Leno's Law is the fix.
Senate Bill 1392, backed by Republican Sen. Shannon Grove and Democrat Sen. Dave Cortese, would exempt qualifying classic vehicles built before the 1981 model year from the biennial smog check entirely.
To qualify, an owner needs a historical license plate and collector vehicle insurance.
The exemption expands gradually, adding one model year at a time, until it reaches pre-1986 vehicles by 2032.
The bill passed the full California Senate and cleared the Assembly Transportation Committee 13-0.
It now sits in the Assembly Appropriations Committee – the same body that shelved last year's version before it ever reached a floor vote.
California lawmakers have until the end of August to send it to the governor.
Classic Car Owners Are Fleeing California Over Smog Check Rules
Classic cars built before 1981 – the vehicles targeted by SB 1392 – represent less than half a percent of all vehicles on California roads.
They are not daily drivers.
They sit in garages and come out for weekend shows, charity runs, and Sunday morning drives.
Meanwhile, California's automotive aftermarket industry – the shops, the parts suppliers, the restoration specialists – generates $40 billion in economic activity and supports 150,000 jobs.
Every neighboring state figured this out years ago.
Arizona exempts pre-1967 vehicles and anything registered as a collectible.
Nevada lets pre-1968 vehicles off completely.
Oregon does not even require smog testing outside two metro areas.
California – the state that invented hot rod culture, where Hollywood put chrome and horsepower on screen for fifty years – is the only one treating a '69 Camaro like a diesel bus.
The Bay Area Air Quality Management District still opposes it, warning the bill creates an opening for everyday drivers to skip emissions testing entirely.
That argument does not survive contact with the bill's actual text.
The collector insurance requirement and historical plate designation create a narrow, verifiable pathway – not a loophole anyone drives a daily commuter car through.
The same bureaucratic instinct that made it impossible to get your grandfather's Chevelle tested is now lecturing Californians about exploitation.
Sacramento has never explained why a car driven 500 miles a year to a car show does more damage than the bureaucracy driving collectors out of the state.
Enthusiasts have been relocating to Arizona, Texas, and Nevada for years – taking their cars, their money, and their car shows with them.
California spent a century building that culture and Sacramento has spent two years strangling it with smog forms.
The bill is sitting in committee right now with a hard deadline closing in.
Leno already watched Sacramento bury this once.
The question is whether California's green lobby gets to do it again.
