Truck noise on Santa Clara County roads is governed by California Vehicle Code sections 23130 and 27007, capping engine and stereo noise. SCC unincorporated commercial zones add early-morning loading restrictions enforced by Title B.
California Vehicle Code §23130 sets maximum noise levels for trucks operating on highways: 86 dBA at 50 feet for vehicles over 6,000 pounds. Vehicle Code §27007 prohibits stereo amplification audible at 50 feet. These state standards apply uniformly across Santa Clara County, including unincorporated areas, San Jose, Sunnyvale, Cupertino, and other cities. SCC Title B and parallel city ordinances supplement state rules by limiting commercial loading-dock activity in unincorporated industrial-residential interface zones to between 7:00 AM and 10:00 PM. Backup-alarm noise from refuse trucks, delivery vans, and concrete mixers is regulated where Cal-OSHA permits ambient-sensitive variants. Idling beyond five minutes violates CARB Airborne Toxic Control Measure 13 CCR §2485.
CHP and city traffic officers issue Vehicle Code citations starting at $238 base fine plus court fees. SCC Title B loading-zone infractions carry $100 to $500 fines. CARB anti-idling citations begin at $300 per truck.
