For decades, classic car enthusiasts in the Golden State faced strict regulatory hurdles that threatened to push post-1975 collector models off the road. The new measure creates a designated path forward for historic automobiles while keeping broader state clean air standards intact.The effort to update these vehicle mandates gained momentum after state lawmakers recognized that limited-production and heavily preserved collector cars contribute minimally to overall smog levels. By distinguishing preserved weekend cruisers from daily commuter vehicles, California establishes a long-awaited regulatory balance that shields classic iron without jeopardizing overall environmental progress.CAGovernor/TwitterSmog Exemptions and Lowrider PlatesOfficially enacted as Senate Bill 1392, the measure commonly known as "Jay Leno's Law" introduces a phased-in smog check exemption for qualifying vehicles produced between the 1976 and 1985 model years. Governor Newsom signed the bill alongside longtime advocate Jay Leno during a special event in Burbank. The legislation provides targeted relief for vehicles that have been trapped in emissions-testing limbo for years.AdvertisementAdvertisementTo qualify under SB 1392, a vehicle must satisfy strict collector parameters designed to prevent abuse. Owners must maintain specialized collector vehicle insurance policies or certify that the car is driven fewer than 1,000 miles per year. Because these vehicles are reserved for car shows, parades, and occasional leisure drives rather than daily commuting, state air quality officials agreed the exemption poses no meaningful risk to California air quality goals.In addition to SB 1392, Governor Newsom signed Assembly Bill 2541 to honor California's rich lowrider culture with a specialized license plate program. Introduced by Assemblymember Mark Gonzales, AB 2541 funds local youth art initiatives while officially celebrating Chicano automotive heritage. Newsom also approved Senate Bill 1069, streamlining the state review process for aftermarket parts manufacturers serving the classic car market.Jay Leno's GarageA Win for the Next GenerationJay Lenos Law represents a sensible, well-crafted victory for car preservation. California has long set the standard for environmental policy, but blanket emissions mandates often unfairly penalized responsible hobbyists who preserve automotive history. By establishing clear annual mileage limits and requiring collector insurance, the state effectively safeguards its air while honoring the craftsmanship of classic American steel.This regulatory update arrives at a crucial moment as interest in collector vehicles continues to expand across fresh demographics. Recent market trends show young buyers are entering the vintage market in record numbers, seeking out retro trucks and classic iron. Protecting these vehicles ensures that California's rich automotive culture remains vibrant, accessible, and legally protected for generations of enthusiasts to come.This story was originally published by Autoblog on Sep 18, 2026, where it first appeared in the News section.
