Summary
Gardena Municipal Code § 8.36.070(14) makes it city policy to enforce the California Vehicle Code's motor vehicle noise and muffler-equipment limits, Sections 23130, 23130.5, 27150, and 27151, on every public right-of-way in the City of Gardena, and § 8.36.070(15) separately bans sounding a vehicle horn for any purpose other than a warning signal.
14. Motor Vehicle Noise Limits. Motor vehicle noise limits on a public right-of-way are regulated as set forth in the California Motor Vehicle Code, Sections 23130 and 23130.5. Equipment violations, which create noise problems, are covered under Sections 27150 and 27151. Any peace officer of any jurisdiction in California may enforce these provisions. Therefore, it shall be the policy of the City to enforce these sections of the California Vehicle Code. 15. Motor Vehicle Horns. It is unlawful for any person to sound a vehicular horn except as a warning signal (Motor Vehicle Code, Section 27001).
Full Breakdown
Rather than write its own decibel table for cars, motorcycles, and trucks, Gardena Municipal Code § 8.36.070(14) adopts the state's noise limits wholesale: California Vehicle Code § 23130 and § 23130.5 govern how loud a motor vehicle may be on a public right-of-way, while §§ 27150 and 27151 cover excessive noise from a defective or missing muffler or other equipment. Section 8.36.070(14) makes enforcing those Vehicle Code sections declared city policy, and specifies that any peace officer from any California jurisdiction, not only Gardena police, may cite a violation.
Subsection 15 adds a separate local horn rule: sounding a vehicle horn for any purpose other than a warning signal is unlawful, referencing Vehicle Code § 27001. Section 8.36.070(16) extends the same noise-disturbance test to motorized recreational vehicles, including motorcycles, go-carts, campers, and dune buggies, operated off the public right-of-way, holding them to the § 8.36.040 exterior standard even on private land. Subsection 18 separately bars idling a stationary vehicle or its attached equipment for more than five minutes in any hour outside of traffic congestion if it violates § 8.36.040.
Repairing, rebuilding, or testing a vehicle, motorboat, or aircraft in a way that creates a noise disturbance across a residential property line is barred under subsection 17, though federally regulated aircraft operations are excluded.
Violations & Fines
A vehicle noise or horn violation under § 8.36.070(14) or (15) is a misdemeanor under § 8.36.090, and any California peace officer, not just Gardena police, can enforce the underlying Vehicle Code sections. Excess idling, off-road recreational vehicle noise, and improper vehicle repair or testing noise under subsections 16 through 18 carry the same misdemeanor classification and are treated as a public nuisance subject to abatement.
