BAR UPDATES · 2026-10-13 · 3 min read

Quick read: The California Bureau of Automotive Repair's Fall 2026 newsletter brings three key updates for drivers: a collector vehicle smog exemption process starting in 2028, expanded noise inspection rules for motorcycles and heavier trucks beginning January 2027, and new windshield replacement disclosure requirements when your vehicle has advanced driver assistance systems. Additionally, BAR suspended four Los Angeles-area repair shops for fraudulent practices, reminding drivers to choose certified stations carefully.

Collector Vehicle Smog Check Exemptions Coming in 2028

The biggest change for classic car owners comes from SB 1392, signed into law in 2026. Starting in 2028, BAR will establish an administrative process to exempt collector motor vehicles from smog check requirements, according to the Fall 2026 newsletter from bar.ca.gov.

Here's the rollout timeline: The exemption begins in 2028 with vehicles manufactured before the 1981 model year. Each subsequent year, the exemption extends by one additional model year, concluding in 2033 when all collector vehicles manufactured before 1986 will qualify for the exemption.

BAR is working with the Department of Motor Vehicles to develop the specific regulations and application process. If you own a classic vehicle, watch for details on the administrative process in late 2027. This phased approach means pre-1981 classics will be first in line, while owners of early-1980s collector vehicles will need to wait a few more years.

Expanded Noise Inspections Start January 1, 2027

If you drive a motorcycle or heavier truck and receive a citation for excessive exhaust noise, new rules take effect January 1, 2027. Assembly Bill 2496 expands BAR Referee noise inspections beyond the current requirement for passenger cars and light trucks under 6,000 pounds.

Starting next year, the noise inspection requirement covers:

• Motorcycles
• Trucks with a gross vehicle weight rating (GVWR) up to 14,000 pounds
• All passenger cars and trucks under 6,000 pounds GVWR (existing requirement)

If you're cited for specified exhaust noise violations, you'll need to correct the issue and obtain a BAR Referee certificate of compliance to provide to the court. Without the certificate, the DMV may prevent your registration renewal. BAR Referee stations conduct these inspections—find pricing information and locations on our network directory.

New Windshield Replacement Disclosure Rules (ADAS-Equipped Vehicles)

While not directly related to smog checks, SB 988 creates important new requirements for drivers whose vehicles have advanced driver assistance systems (ADAS). These systems—which include features like lane departure warnings, adaptive cruise control, and automatic emergency braking—often require recalibration after windshield replacement.

Under the new law, automotive glass shops must now:

• Disclose whether your vehicle is equipped with ADAS
• Inform you whether calibration is required following windshield repair or replacement
• Provide written notice of calibration results
• Supply itemized invoices

Many newer vehicles sold in California include ADAS features, and improper calibration after windshield work can affect these safety systems. The new disclosure requirements help ensure you're informed about necessary calibration services before authorizing repairs.

BAR Cracks Down on Fraudulent Smog Shops

BAR's enforcement actions this quarter underscore the importance of choosing legitimate test stations. Between June and September 2026, BAR suspended registrations of four Los Angeles-area automotive repair dealers following investigations into fraudulent practices.

One suspension in June involved fraudulent, predatory, and deceptive vehicle towing and storage practices. Three additional suspensions from July through September came after investigations found shops issued certificates of compliance without performing required vehicle safety system inspections.

These interim suspension orders remain in place pending final disciplinary decisions. The enforcement actions highlight why drivers should verify their smog check station is properly licensed and follows all testing protocols. If you've experienced a failed smog check or suspect fraudulent practices, you can file a complaint through bar.ca.gov.

What This Means for California Drivers

Most drivers won't see immediate changes to their smog check requirements. The collector vehicle exemption doesn't begin until 2028 and will phase in gradually. The noise inspection expansion affects only vehicles cited for exhaust violations. And the ADAS disclosure rules apply to windshield work, not emissions testing.

The enforcement actions, however, serve as a reminder to choose your smog check station carefully. Use certified stations in our network, and book online to ensure you're working with verified providers who follow proper testing procedures.
