SB 1392 California Senate · 2025-2026 Regular Session

Smog check: exemption: collector motor vehicles.

Summary
Existing law establishes a motor vehicle inspection and maintenance (smog check) program that is administered by the Department of Consumer Affairs. The smog check program requires inspection of motor vehicles upon initial registration, biennially upon renewal of registration, upon transfer of ownership, and in certain other circumstances. Existing law requires all motor vehicles to biennially obtain a certificate of compliance or noncompliance, as provided. Existing law exempts specified vehicles from obtaining the certificate of compliance or noncompliance, including, among others, all motor vehicles manufactured before the 1976 model year. Existing law also exempts from a specified portion of the smog test, both biennially and at transfer, a collector motor vehicle that is insured as a collector motor vehicle, is at least 35 model years old, complies with the exhaust emissions standards for that motor vehicle's class and model year as prescribed by the department, and passes a functional inspection of the fuel cap and a visual inspection for liquid fuel leaks. Existing law defines collector motor vehicle for this purpose to mean a motor vehicle owned by a collector, as defined, used primarily in shows, parades, charitable functions, and historical exhibitions for display, maintenance, preservation, and not used primarily for transportation. This bill would expand the definition of a collector motor vehicle to include a motor vehicle that is at least 35 model years old and complies with certain regulations that are required to be adopted by the Bureau of Automotive Repair, as specified. The bill would, beginning January 1, 2028, exempt specified collector motor vehicles manufactured before the 1981 model year from the requirement to obtain a certificate of compliance or noncompliance upon initial registration, biennially upon renewal of registration, or upon transfer of ownership. The bill would extend the applicability of this exemption by one model year each year until the final extension takes effect on and after January 1, 2033, that would exempt specified collector motor vehicles manufactured before the 1986 model year from the requirement to obtain the certificate of compliance or noncompliance. The bill would be known, and may be cited, as Jay Leno's Law.

MODERATE
The phased timeline for extending smog check exemptions to collector motor vehicles has been delayed by one year for each successive phase after the initial 2028 start date. The first exemption (pre-1981 vehicles) still takes effect January 1, 2028, but each subsequent year's expansion is pushed back one year, so the final phase covering pre-1986 vehicles now takes effect January 1, 2033 instead of January 1, 2032. This gives regulators an additional year to implement the program before the full exemption applies.
Scope change
The overall scope of the bill is unchanged - it still exempts collector motor vehicles from smog check requirements on a phased basis. However, the timeline for full implementation is extended by one year, meaning fewer vehicles will be exempt in any given year through 2033 compared to the prior version.
TIMELINE

The effective date for exempting pre-1982 collector motor vehicles from smog checks changed from January 1, 2028 to January 1, 2029.

The effective date for exempting pre-1983 collector motor vehicles changed from January 1, 2029 to January 1, 2030.

The effective date for exempting pre-1984 collector motor vehicles changed from January 1, 2030 to January 1, 2031.

The effective date for exempting pre-1985 collector motor vehicles changed from January 1, 2031 to January 1, 2032.

The effective date for exempting pre-1986 collector motor vehicles (the final phase) changed from January 1, 2032 to January 1, 2033.
