Vehicle Noise: Chino vs Victorville
How do vehicle noise rules compare between Chino, CA and Victorville, CA?
Chino, CA
San Bernardino County
On-road motor-vehicle exhaust and engine noise is primarily a matter of California Vehicle Code, not the Chino Municipal Code. Vehicle Code §27150 requires every motor vehicle to have an adequate muffler in constant operation, with no cutout, bypass, or similar device. §27151 prohibits modifying an exhaust system to amplify or increase noise; for passenger vehicles under 6,000 lb GVWR (other than motorcycles), an exhaust sound level over 95 dBA (measured per SAE J1492 / J1169) is a violation. CHP and Chino Police enforce these under state law. Article 2.5 (Veh. Code §§27200–27207) sets vehicle-class noise limits (e.g., motorcycles: 80 dBA at 50 ft for post-1985 models). Loud cars off public roadways, or stationary vehicle noise (revving in a driveway, idling refrigerated trucks), fall under Chino CMC §9.40 exterior noise standards (65 dBA day / 55 dBA night at residential property line). Cal. Vehicle Code §21461 preempts cities from regulating equipment on vehicles operated on public highways beyond what state law allows.

Chino FAQ
Can Chino set its own decibel limit for car exhausts louder than state's 95 dBA?
No. Cal. Veh. Code §21461 and the broader state-law preemption doctrine (per People v. McKendrick and progeny) prevent cities from imposing equipment requirements stricter than the Vehicle Code for vehicles on public roads. Chino's §9.40 exterior noise standards do not apply to passing traffic on public streets.
Trucks idle all night at the warehouse across the street — is that legal?
No. CARB's anti-idling rule (13 CCR §2485) limits heavy-duty diesel truck idling to 5 minutes, with limited exceptions (sleeper-berth use, traffic, emergency). Also, CMC §9.40.040 applies a 55 dBA nighttime limit at the residential property line — a running diesel typically exceeds this. Report to CARB (1-800-END-SMOG) and Chino Code Enforcement (909-334-3263).
