While the state is home to one of the most vibrant collector-car cultures in the world, the regulatory burden on owners of legacy internal combustion vehicles has historically been heavy. However, a recent legislative development, officially known as Senate Bill 1392 and colloquially dubbed &quot;Leno\u2019s Law,&quot; marks a pivot in how the state handles the maintenance and operation of vintage automobiles. By introducing a rolling smog exemption for specific older vehicles, the state has acknowledged the cultural and historical significance of the collector-car hobby, though the practical application of this law remains limited in its scope.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_84 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/propernews.co\/?p=7413\/#The_Legislative_Framework_of_SB_1392\" >The Legislative Framework of SB 1392<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/propernews.co\/?p=7413\/#Strict_Criteria_for_Eligibility\" >Strict Criteria for Eligibility<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/propernews.co\/?p=7413\/#Historical_Context_and_Advocacy_Efforts\" >Historical Context and Advocacy Efforts<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/propernews.co\/?p=7413\/#Analyzing_the_Impact_Is_it_Enough\" >Analyzing the Impact: Is it Enough?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/propernews.co\/?p=7413\/#The_Broader_Implications_for_Californias_Automotive_Scene\" >The Broader Implications for California\u2019s Automotive Scene<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/propernews.co\/?p=7413\/#Conclusion_A_Measured_Step_Forward\" >Conclusion: A Measured Step Forward<\/a><\/li><\/ul><\/nav><\/div>\n<h3><span class=\"ez-toc-section\" id=\"The_Legislative_Framework_of_SB_1392\"><\/span>The Legislative Framework of SB 1392<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Governor Gavin Newsom\u2019s recent signing of Senate Bill 1392 introduces a structured, albeit gradual, relief for owners of pre-1981 vehicles. Under the current California regulatory regime, vehicles manufactured prior to 1976 are already exempt from the biennial smog certification requirements that plague most motorists in the state. SB 1392 effectively extends this rolling exemption window, allowing vehicles manufactured from 1981 onwards to eventually qualify for similar status.<\/p>\n<p>The implementation follows a specific, multi-year schedule. Beginning in January 2028, vehicles built before 1981 will become eligible for the exemption. From that point forward, the exemption threshold will expand by one model year annually. By the time the calendar reaches 2033, the exemption will cover vehicles manufactured up to 1986. This methodical approach is designed to balance the state&#8217;s air quality objectives\u2014managed by the California Air Resources Board (CARB)\u2014with the preservation of historical automotive assets.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Strict_Criteria_for_Eligibility\"><\/span>Strict Criteria for Eligibility<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Despite the excitement surrounding the bill&#8217;s passage, legal experts and automotive advocates have been quick to temper expectations. The law is not a blanket exemption for all older vehicles; rather, it includes stringent eligibility requirements that significantly narrow the pool of beneficiaries.<\/p>\n<p>To qualify for the exemption, a vehicle must meet one of two primary conditions: it must be registered specifically as a collector car, or it must be driven fewer than 1,000 miles per calendar year. The latter condition is verified through odometer readings submitted during the registration renewal process. For the average car enthusiast who enjoys driving their classic vehicle on weekends, road trips, or to frequent car shows, the 1,000-mile cap serves as a significant hurdle. Furthermore, vehicles that are used as primary transportation\u2014or those that are modified in ways that deviate significantly from original emissions configurations\u2014may still find themselves tethered to the traditional testing cycle.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Historical_Context_and_Advocacy_Efforts\"><\/span>Historical Context and Advocacy Efforts<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The movement to pass SB 1392 was championed by a coalition of automotive stakeholders, including the Specialty Equipment Market Association (SEMA) and prominent automotive personalities like Jay Leno. For years, advocates have argued that the environmental impact of collector vehicles is negligible compared to the millions of modern, high-mileage daily drivers on California roads. <\/p>\n<p>The legislative journey was spearheaded by Senators Dave Cortese and Shannon Grove. Their argument focused on the &quot;automotive heritage&quot; of California, positing that the state\u2019s strict smog laws were unintentionally penalizing the hobbyist community while offering little in terms of tangible air quality improvements. By framing the bill as a means to protect the preservation of history, proponents successfully navigated the legislative process in a statehouse that is typically wary of rolling back emissions standards.<\/p>\n<p>Mike Spagnola, CEO of SEMA, praised the outcome as a &quot;historic win&quot; for the automotive community. In a statement released following the signing, Spagnola noted that the bill recognizes the role of vintage vehicles in connecting generations and maintaining the state&#8217;s cultural narrative. He emphasized the collaborative nature of the effort, crediting the &quot;unrelenting passion&quot; of the advocacy groups and the bipartisan support the bill garnered in the legislature.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Analyzing_the_Impact_Is_it_Enough\"><\/span>Analyzing the Impact: Is it Enough?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>From a policy analysis perspective, SB 1392 represents a compromise. Environmental advocacy groups initially expressed concern that any reduction in smog testing requirements could degrade air quality. To address these concerns, the bill\u2019s authors had to limit the scope of the exemption. The result is a policy that provides relief to the &quot;garage-queen&quot; segment of the collector market\u2014those who rarely drive their vehicles\u2014while leaving the active driving enthusiast largely unaffected.<\/p>\n<p>Data from the California Department of Motor Vehicles suggests that the number of vehicles classified as &quot;collector&quot; or &quot;historical&quot; is a small fraction of the total registered fleet. Consequently, while the law is a victory for the specific subset of owners who keep their mileage low, it does not constitute a broad deregulation of vintage car ownership. <\/p>\n<p>Furthermore, the law does not address the cost of maintaining older emissions equipment. Even for those who qualify, the challenge of finding replacement parts for 40-year-old catalytic converters and smog pumps remains a significant barrier to keeping these vehicles compliant. Critics of the bill argue that the state should have focused on &quot;fix-it&quot; grants or subsidies for emissions-compliant repairs rather than focusing solely on exemptions for low-mileage vehicles.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"The_Broader_Implications_for_Californias_Automotive_Scene\"><\/span>The Broader Implications for California\u2019s Automotive Scene<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The passage of Leno\u2019s Law raises questions about the future of classic car ownership in the state. As California moves toward its goal of banning the sale of new internal combustion engine vehicles by 2035, the focus on legacy vehicles is expected to intensify. SB 1392 establishes a precedent: the state is willing to create exceptions for vehicles that are not used as daily commuters. <\/p>\n<p>This sets a potential framework for future legislation. Should SB 1392 prove successful without causing a measurable decline in regional air quality, it could serve as a model for further expanding the rolling exemption beyond the 1986 model-year cap. However, such a move would require substantial political capital and continued evidence that the classic car hobby is not a significant contributor to the state\u2019s total tailpipe emissions.<\/p>\n<p>For the enthusiast, the takeaway is clear: record-keeping is more important than ever. To benefit from this law, owners must be diligent about their documentation. Maintaining accurate mileage logs and ensuring that the vehicle is correctly classified with the DMV will be essential once the law takes effect in 2028. <\/p>\n<h3><span class=\"ez-toc-section\" id=\"Conclusion_A_Measured_Step_Forward\"><\/span>Conclusion: A Measured Step Forward<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Senate Bill 1392 is a significant, albeit modest, achievement for the California automotive community. It acknowledges that the preservation of classic automobiles is a legitimate public interest and that the regulatory burden of modern smog testing is often incompatible with the reality of occasional vehicle use. <\/p>\n<p>While it is not the sweeping reform that some enthusiasts might have desired, it provides a clear pathway for the survival of the classic car hobby in the state. By limiting the exemption to low-mileage and specifically registered collector vehicles, the law successfully mitigates concerns regarding environmental impact while providing relief to those who value the preservation of automotive history. As the state approaches the 2028 start date, the automotive community will be watching closely to see if this model can be expanded or if it will remain a niche provision for a select few. For now, the bill stands as a testament to the power of organized advocacy and a rare moment of alignment between the interests of California\u2019s car culture and its legislative body.<\/p>\n<!-- RatingBintangAjaib -->","protected":false},"excerpt":{"rendered":"<p>California, a state often characterized by its stringent environmental regulations and aggressive push toward electric vehicle adoption, has long maintained a complex relationship with the automotive enthusiast community.
