Rialto Municipal Code Section 9.50.040 makes it a misdemeanor to play a car stereo or other in-vehicle sound device plainly audible at 50 feet, or beyond the property line on private property. Police may immediately confiscate the sound components or even the vehicle.
Section 9.50.040 targets boom cars: no person may operate or occupy a motor vehicle while playing any radio, stereo, television, or other sound device plainly audible 50 feet from the vehicle on any public right-of-way or public place, or beyond the property line when on private property. Unlike most noise violations in Rialto, this is a misdemeanor and public nuisance, and officers may immediately confiscate and impound the amplifying components, or the vehicle itself if components cannot be removed without damage. Section 9.50.030(A)(1)-(3) separately prohibits unnecessary horn sounding, engine racing while stationary, and operating vehicles with modified or removed mufflers that increase noise above factory levels.
A misdemeanor and public nuisance under Sections 9.50.040 and 9.50.120, with fines of $250 to $1,000 per Section 9.50.130 plus immediate impoundment of equipment or vehicle. Owners may request return in writing within seven calendar days.
