f you're a California driver, you've probably heard the rumors swirling around: Is California getting rid of smog checks in 2025? With the state's push toward cleaner air and zero-emission vehicles, it's easy to wonder if these mandatory inspections are on their way out. The short answer?

Current Smog Check Requirements in CaliforniaSmog checks, officially known as Smog Check inspections, are a key part of California's efforts to reduce vehicle emissions and improve air quality. Administered by the Bureau of Automotive Repair (BAR), these inspections ensure vehicles meet emission standards before registration or sale.

For most vehicles, smog checks are required biennially (every two years) upon registration renewal in designated areas, which include most urban and suburban counties like Los Angeles, San Francisco, and yes, Pasadena. This applies to gasoline-powered, hybrid, and alternative-fuel vehicles from model year 1976 and newer, as well as diesel vehicles from 1998 and newer.
​
Key basics:

• Frequency: Every two years for renewal if your DMV notice says "Smog Certification Required." Also required for change of ownership (unless the vehicle is very new) and first-time registration in California.
• Exemptions: Vehicles eight model years and newer pay a smog abatement fee instead of getting inspected for renewal. For example, a 2018 model year vehicle in 2025 would still qualify for this fee rather than a full check. Other exemptions include gasoline vehicles 1975 and older, diesels 1997 and older (or over 14,000 lbs GVWR), electric vehicles, and motorcycles.
• County-Specific Rules: While smog checks are statewide for sales and initial registrations, biennial renewals are required only in smog-prone areas. Check your DMV notice or visit BAR's website to confirm.

2025 Updates and Changes to Smog Checks

As of October 14, 2025, we're already past the implementation date for some key changes. Starting October 1, 2025, the BAR introduced stricter emission standards and tougher testing protocols, including updated readiness monitor limits. This means inspections will more rigorously check components like exhaust systems, fuel injection, and onboard diagnostics, making it potentially harder for older or poorly maintained vehicles to pass.
There were also legislative efforts to adjust exemptions. For instance, Senate Bill 712 (SB 712), often called "Leno's Law" after comedian Jay Leno's support, proposed a rolling exemption for classic cars 35 years and older, starting in 2027. The bill aimed to fully exempt these collector vehicles from biennial and transfer inspections if insured as classics. However, it failed to pass in the California legislature in August 2025, so no new exemptions are in place.
​
These updates reflect California's ongoing commitment to cleaner air, but they don't signal the end of smog checks. Instead, the program is evolving to handle modern vehicles better while maintaining strict controls on emissions.

Common Myths About Smog Checks Being Eliminated.

One of the biggest myths is that California is getting rid of smog checks altogether in 2025. This rumor likely stems from the state's ambitious environmental goals, like requiring all new cars sold to be zero-emission by 2035. While electric vehicles are exempt from smog checks, traditional gas and diesel vehicles still need them to ensure they don't contribute excessively to pollution.

Another myth: Classic cars are now exempt due to new laws. As mentioned, proposals like SB 712 didn't pass, so 1976-and-newer classics still require checks unless they fall under existing exemptions.
Smog checks remain essential because California has some of the worst air quality in the nation, and vehicles are a major source of smog-forming pollutants. Eliminating them would undermine progress toward healthier air.

For accurate info, always check official sources like the California DMV or BAR.

How to Prepare for Your Smog Check

Preparation is key to passing your smog check and avoiding retest fees. Here are some tips:

• Check Engine Light: Ensure it's off. If on, get diagnostics to determine issue.
• Maintenance: Recent oil change, clean air filter, and tuned-up engine can help. Drive 100-200 miles after repairs to reset monitors.
• Avoid Modifications: Restore any aftermarket parts to stock or CARB-approved.
• Battery Work: If you've disconnected the battery, drive sufficiently to ready the OBD system.
