California’s ‘Leno’s Law’ Signed, Expanding Classic Car Smog Exemptions

SACRAMENTO — September 16, 2026

In a landmark decision for classic car enthusiasts, California Governor Gavin Newsom has officially signed Senate Bill 1392, commonly referred to as ‘Leno’s Law’. This legislation significantly expands the smog exemption criteria for classic vehicles, allowing more owners to preserve their vintage automobiles without the burden of stringent emissions testing.

The bill, which was signed into law on September 16, 2026, at the California State Capitol, directly impacts car owners of vehicles that are 30 years or older. Previously, classic cars were subject to smog checks, which often posed a financial and logistical challenge for owners wishing to maintain their vehicles in compliance with California’s rigorous environmental standards. With the enactment of ‘Leno’s Law’, these vehicles will now be exempt from such requirements, reflecting a growing recognition of the cultural and historical significance of classic cars.

The legislation was championed by Senator Anthony Portantino, who cited the importance of preserving automotive history and the cultural identity associated with classic cars. The bill garnered support from various automotive clubs and enthusiasts, including the well-known comedian and car collector Jay Leno, after whom the law is informally named. Leno has been a vocal advocate for classic car preservation, arguing that these vehicles represent not just personal passion but also a significant part of American history.

The decision to expand smog exemptions comes amid a broader national conversation about environmental regulations and their impact on car culture. California has long been at the forefront of environmental policy, often setting trends that influence legislation in other states. However, the balance between environmental responsibility and the preservation of automotive heritage has become increasingly contentious.

As the state grapples with climate change and air quality issues, the implications of ‘Leno’s Law’ are multifaceted. Critics argue that easing emissions standards for older vehicles could undermine California’s ambitious environmental goals. Proponents, however, contend that classic cars are typically driven less frequently and contribute minimally to overall emissions, thus justifying the exemption.

This development is receiving heightened attention now due to the ongoing debates surrounding environmental policy and the automotive industry’s transition towards electric vehicles. As California continues to lead in setting environmental standards, the implications of this law could resonate beyond state lines, influencing similar legislative efforts in other regions.

Looking ahead, the immediate next steps involve the implementation of the law, which will require the California Department of Motor Vehicles to adjust its regulations accordingly. This could lead to a surge in classic car registrations as owners take advantage of the new exemptions. Additionally, the law may prompt discussions about further adjustments to emissions standards for other vehicle categories, as stakeholders assess the balance between environmental goals and cultural preservation.
