California Bill To Amend 2018 Exhaust Noise Law Signed by Governor

Governor Gavin Newsom of CA has approved SEMA-supported legislation (SB 112) that restores “fix-it” tickets for cars suspected of violating the state’s exhaust noise limit, allowing car owners 30 days to correct violations. SB 112 amends a 2018 law (AB 1824) that removed this ability and created great concern within the auto enthusiast community.

“On behalf of the over 1,700 SEMA member companies in California, SEMA thanks Gov. Newsom for signing this critical legislation into law,” said Daniel Ingber, SEMA’s Vice President for Legal and Government Affairs. “With his signature, Gov. Newsom restored due process for motorists in the Golden State.”

SB 112 includes text from SEMA-sponsored AB 390, which was authored by Assembly Members Jim Frazier (D-Discovery Bay) and Tim Grayson (D-Concord) in early 2019. Under normal legislative procedure, AB 390 would not have been implemented until January 2020, but SB 112 is effective immediately.

SB 112 was championed in the legislature by Assembly Members Grayson, Tasha Boerner Horvath (D-Oceanside), Phil Ting (D-San Francisco), Phil Chen (R-Diamond Bar), and Senator Holly Mitchell (D-Los Angeles).

Since 2003, exhaust systems installed on motor vehicles in California with a manufacturer’s gross vehicle weight rating of under 6,000 pounds, other than motorcycles, may not exceed a sound level of 95 decibels when tested under a Society of Automotive Engineers (SAE) procedure. SB 112 does not change this.
