Lawmakers Kill “Jay Leno’s Law”: California Classic Car Smog Check Rules Stay in Place After SB 712 Rejection
LOS ANGELES (Times Media Service) — California lawmakers rejected SB 712, a high-profile proposal backed by Jay Leno that would have exempted collector cars 35 years and older from smog checks; the Assembly Appropriations Committee placed the measure on the suspense file Aug. 30, 2025.
- What happened: SB 712 was held on the Assembly Appropriations Committee suspense file and was not advanced, effectively killing the bill on Aug. 30, 2025 (CalMatters; LAist).
- What it would have done: SB 712, dubbed “Jay Leno’s Law,” would have exempted vehicles 35 years and older from smog checks if registered and insured as collector cars (AftermarketMatters).
- Current law: Only vehicles from 1975 and older are exempt; gasoline, hybrid and alternative-fuel cars from model year 1976 onward must pass smog checks (Bureau of Automotive Repair smog check rules).
Background: California’s smog rules today
California requires smog checks for most vehicles to meet state air quality goals. Under the Bureau of Automotive Repair, gasoline, hybrid and alternative-fuel vehicles from 1976 or newer must pass a smog inspection to register or renew registration. Exemptions apply to cars built in 1975 or earlier, and to certain diesel and electric vehicles.
Supporters of existing rules say the inspections help California meet strict clean-air standards and protect public health in dense urban regions like Los Angeles.
What SB 712 proposed
SB 712 would have created a rolling exemption for vehicles 35 years and older, provided they were registered as collector cars and covered by appropriate collector insurance. Proponents said the change would apply to vehicles kept primarily for shows, parades and limited use, not to everyday drivers (AftermarketMatters).
Proponents’ arguments: Collectors drive rarely, so the emissions impact would be minimal; the change would protect car culture, help small restoration businesses, and reduce regulatory burden on enthusiasts.
Jay Leno’s role and public push
Comedian and car collector Jay Leno publicly supported SB 712, testified before lawmakers, and framed the proposal as protecting automotive heritage and hobby businesses. Leno’s visibility helped the bill pass the Senate Transportation Committee with bipartisan support (LAist).
Bill’s fate: suspense file and rejection
After passing a Senate committee, SB 712 reached the Assembly Appropriations Committee, which placed it on the suspense file — a procedural step for bills with potential fiscal impact or controversy. On Aug. 30, 2025, the committee did not advance the bill, effectively killing it. This outcome is often issued without a detailed public vote explanation (CalMatters; LAist).
Why lawmakers may have balked
- Environmental priorities: California’s strict clean-air and climate goals made some lawmakers wary of expanding smog exemptions (LAist).
- Fiscal uncertainty: The Appropriations Committee often pauses measures with potential cost or administrative impacts; the bill may have implied new costs or enforcement questions (CalMatters).
- Political caution: High-profile backing draws attention and opposition; the suspense file is a low-profile way to stop measures without a public showdown.
Industry and supporter reaction
Supporters, including State Sen. Shannon Grove and industry groups such as SEMA, voiced disappointment and argued the bill would affect only a tiny share of vehicles while helping businesses that supply parts and services to collectors (AftermarketMatters).
Opponents cautioned that limited driving can add up across many vehicles and feared the exemption could set a precedent for more carve-outs (CalMatters).
What the rejection means now
Immediate outcome: California’s current smog rules remain in place. Owners of post-1975 cars that are not pre-1976 models must continue to obtain smog checks to register or renew (Bureau of Automotive Repair smog check rules).
Collectors and hobbyists remain subject to the same emissions rules as most other car owners unless they already qualify for other exemptions.
Implications for Los Angeles, California
Economic impact
- Small businesses: L.A. hosts many shops that restore and sell parts for classic cars; supporters argued SB 712 would have eased burdens, while its rejection keeps steady smog-related demand (AftermarketMatters).
- Consumer costs: Classic-car owners in L.A. will continue to pay for smog checks when registering or renewing post-1975 vehicles.
Political consequences
- Local representatives: Officials will hear from both enthusiasts and environmental advocates; the defeat reduces immediate pressure but keeps the issue alive for future sessions.
- Policy signals: The decision signals caution about loosening air-quality rules in regions like Los Angeles (LAist).
Social and community effects
- Car culture: Clubs and hobbyists view the rejection as a setback; advocacy may shift toward narrower fixes or pilot programs.
- Public health: Residents in high-pollution neighborhoods may view the outcome as supporting clean-air priorities.
Practical applications for drivers
Compliance: Drivers with cars newer than 1975 should plan to continue smog testing for registration and renewal. Owners who believe their vehicles qualify as true collector cars can consult the Bureau of Automotive Repair and insurers for existing exemptions or classifications.
Advocacy path: Industry groups can pursue alternative measures — exemptions for very-low-mileage vehicles, streamlined testing for preserved cars, or pilot programs — to balance hobbyist relief with environmental concerns (CalMatters; LAist).
Legal and regulatory next steps
- Future legislation: Rejection is not permanent — lawmakers may return with narrower bills, pilot programs, or compromises addressing environmental and fiscal concerns.
- Administrative options: The Bureau of Automotive Repair and state agencies could consider guidance or rule changes affecting enforcement or collector classifications without new legislation.
