California is known for having some of the most polluted cities in the United States, but Jay Leno believes classic cars aren’t to blame. Now, he’s seeking government support to reinforce his stance.
On Wednesday, California State Senator Shannon Grove revealed her collaboration with the former Tonight Show host to introduce Senate Bill 712 to the California State Senate. Dubbed “Leno’s Law,” the proposed legislation aims to eliminate the biennial smog check requirement for collector vehicles manufactured after 1975.
Grove, who was born and currently serves in Bakersfield, CA—one of the nation’s most polluted cities—carefully avoided referencing that fact when announcing the bill. Instead, she and Leno emphasized the importance of preserving what Grove called California’s “rich automotive heritage,” highlighting the fact that some of the earliest classic cars were manufactured in the state.

“These rolling pieces of history are more than just vehicles—they have strong cultural ties in our communities and support thousands of jobs in the aftermarket parts industry,” Grove stated on Instagram. “Senate Bill 712 will update the current law to include all classic cars that are 35 years or older, allowing enthusiasts to enjoy their hobby without burdensome restrictions that are pushing collectors and industry businesses out of the state.”
Leno echoed this sentiment, underscoring California’s deep-rooted connection to classic cars. “California’s rich classic car culture, sparked by the post-war hot rod boom and fueled by Hollywood’s fascination with chrome and horsepower, has made this state a paradise for enthusiasts like me,” Leno said in Grove’s official statement. “California’s smog check laws for classic cars need to be updated—they are inconsistent from state to state, and California’s regulations don’t align with those of its neighbors.”

Although vintage vehicles—such as the estimated 181 cars and 160 motorcycles owned by Leno—do emit considerable pollutants, including carbon dioxide and nitrogen dioxide, supporters of the bill argue that these cars primarily remain in garages as collector’s items rather than daily drivers.
“Senator Grove’s bill provides a practical solution for collector vehicle owners, allowing them to enjoy their passion without the burden of unnecessary regulations,” said Mike Spagnola, CEO of the Specialty Equipment Market Association (SEMA), in an interview with LSX Magazine. “These vehicles are rarely driven, meticulously maintained, and make up only a small percentage of the cars on the road. By exempting collector vehicles from smog checks, we can ensure that these historical treasures are preserved for future generations.”
