California Governor Newsom Signs SB 1392, Exempting More Classic Cars from Smog Tests

LOS ANGELES — September 16, 2026

In a notable development for classic car enthusiasts and the automotive industry, California Governor Gavin Newsom has signed Senate Bill 1392, commonly referred to as “Leno’s Law,” which exempts a broader range of classic cars from state smog tests. This legislation, signed on September 16, 2026, is poised to reshape the landscape for car collectors and vintage automobile aficionados in the state.

SB 1392 expands the existing exemptions for classic vehicles, allowing cars manufactured before 1980 to bypass smog checks. Previously, only vehicles built before 1976 were eligible for such exemptions. This change is significant, as it acknowledges the cultural and historical value of classic cars while addressing the concerns of collectors who argue that these vehicles are often well-maintained and driven infrequently.

The bill was championed by Senator Anthony Portantino and has garnered support from various automotive clubs and organizations, including the Classic Car Club of America. The legislation is named after comedian and car collector Jay Leno, who has been an outspoken advocate for classic car preservation and the reduction of regulatory burdens on vintage vehicles.

The decision to exempt more classic cars from smog tests was triggered by a growing movement among car collectors and enthusiasts who argue that the stringent emissions regulations disproportionately affect the classic car community. Advocates for the bill contend that older vehicles, when properly maintained, do not significantly contribute to air pollution compared to modern cars.

This legislative change is receiving attention now due to the increasing popularity of classic cars as investments and collectibles, as well as a broader cultural shift towards valuing automotive history. The classic car market has seen a resurgence, with prices for vintage models skyrocketing in recent years, making this exemption particularly relevant for collectors and investors alike.

The implications of SB 1392 extend beyond the classic car community. The automotive industry in California, which is a significant economic driver, may experience shifts in consumer behavior as collectors feel more empowered to invest in vintage vehicles without the looming concern of costly emissions compliance. Additionally, this law could influence similar legislative efforts in other states, as car enthusiasts advocate for more lenient regulations nationwide.

Looking ahead, the implementation of SB 1392 will likely prompt discussions about the balance between environmental regulations and the preservation of automotive heritage. Stakeholders in the automotive industry, including manufacturers and environmental groups, may seek to engage in dialogue regarding the long-term impacts of this legislation. Furthermore, as the classic car market continues to evolve, we may see additional legislative efforts aimed at addressing the needs and concerns of collectors while ensuring environmental standards are met.
