Vehicle noise on Rialto streets is governed primarily by California Vehicle Code §27150 et seq. (mandatory functioning muffler; no modified exhaust) and §23130 (vehicle decibel limits by class). Rialto Municipal Code Title 10 (Vehicles and Traffic) and Ch. 9.50 (Noise Control) prohibit loud sound systems and idling nuisances; CARB 13 CCR §2485 caps heavy-duty diesel idling at 5 minutes.
California preempts most on-road vehicle equipment noise via Veh. Code §27150 (every motor vehicle shall be equipped with a muffler in good working order to prevent excessive or unusual noise) and §27151 (no modification to exceed manufacturer limits). §23130 sets numeric dBA limits at 50 ft for passenger vehicles (80 dBA under 35 mph) and trucks (88 dBA under 35 mph). Vehicle stereos audible 50 ft from the vehicle are a Veh. Code §27007 violation. Within Rialto, idling diesels at warehouses and on truck routes are restricted to 5 minutes (13 CCR §2485, CARB). City ordinance Ch. 9.50 covers stationary vehicle noise on private property; Title 10 covers on-street.
Veh. Code §27150 modified exhaust: correctable citation (fix-it) plus base fine; uncorrected can exceed $200 with assessments. §27007 stereo: infraction ($178 typical bail). §23130 dB-limit: infraction. 13 CCR §2485 idling: $300 minimum. Local Ch. 9.50: infractions per Cal. Gov. Code §36900 ($100/$200/$500).
