The FIA, international motorsport's governing body, has thrown its weight behind California's proposed "Leno's Law," a measure designed to exempt classic and collector cars from the state's increasingly strict emissions regulations. Named after former Tonight Show host Jay Leno, a celebrated car enthusiast, the legislation targets vehicles that represent automotive history and cultural significance.

California's emissions standards rank among the world's toughest. The state has progressively tightened tailpipe requirements and pushed toward electrification, creating friction with owners of vintage, collectible, and purpose-built machines that cannot feasibly meet modern pollution controls. These classics range from pre-1970s muscle cars to hand-built exotics and historically significant race vehicles.

Leno's Law would carve out a formal exemption pathway for vehicles meeting specific age, mileage, and usage criteria, allowing them to remain registered and driven without expensive retrofit mandates or operational restrictions. The FIA's backing adds international credibility to the effort, signaling that preserving automotive heritage aligns with broader motorsport governance priorities.

The rule addresses a genuine tension in transportation policy. California pursues legitimate air quality and climate goals, yet blanket enforcement against low-use collector vehicles produces minimal environmental benefit while threatening the survival of irreplaceable mechanical history. A car driven 500 miles annually contributes negligibly to statewide emissions totals, yet full compliance could render it undriveable.

Supporters emphasize that exemptions for registered collector cars represent a balanced compromise. Insurers and enthusiast groups have established clear definitions: vehicles over 25 to 40 years old, documented collector status, and demonstrable low annual mileage tiers qualify. These parameters limit the exemption to genuinely historic machines rather than creating loopholes for daily-driver emissions dodging.

The legislation reflects growing recognition that conservation of automotive culture merits policy
