Summary
Car sound systems audible inside any occupied home between 10 p.m. and 8 a.m., or beyond 100 feet at any time, violate Jurupa Valley law. Off-highway vehicles need mufflers and spark arresters and must not exceed 96 dBA.
A. Motor Vehicles. 1. Off-Highway Vehicles. a. No person shall operate an off-highway vehicle unless it is equipped with a USDA-qualified spark arrester and a constantly operating and properly maintained muffler. A muffler is not considered constantly operating and properly maintained if it is equipped with a cutout, bypass or similar device. b. No person shall operate an off-highway vehicle unless the noise emitted by the vehicle is not more than ninety-six (96) dBA if the vehicle was manufactured on or after January 1, 1986 or is not more than one hundred one (101) dBA if the vehicle was manufactured before January 1, 1986. For purposes of this subsection, emitted noise shall be measured a distance of twenty (20) inches from the vehicle tailpipe using test procedures established by the Society of Automotive Engineers under Standard J-1287. 2. Sound Systems. No person shall operate a motor vehicle sound system, whether affixed to the vehicle or not, between the hours of ten p.m. and eight a.m., such that the sound system is audible to the human ear inside any inhabited dwelling. No person shall operate a motor vehicle sound system, whether affixed to the vehicle or not, at any other time such that the sound system is audible to the human ear at a distance greater than one hundred (100) feet from the vehicle. Sound level measurements may be used, but are not required to establish a violation of this subsection.
Full Breakdown
Municipal Code section 11.05.060(1), enacted by Ordinance No. 2012-01, sets two vehicle-specific standards. Off-highway vehicles must carry a USDA-qualified spark arrester and a properly maintained muffler without cutouts or bypasses, and may not emit more than 96 dBA (vehicles built on or after January 1, 1986) or 101 dBA (older vehicles), measured 20 inches from the tailpipe under SAE Standard J-1287. Motor vehicle sound systems, whether installed or portable, may not be audible inside any inhabited dwelling from 10 p.m. to 8 a.m., nor audible more than 100 feet from the vehicle at any other time. Ordinary on-road vehicle noise is otherwise exempt from the chapter because the state Vehicle Code occupies that field.
Violations & Fines
Each special sound source violation is separately punishable, with administrative fines of $200, $500, $750, then $1,000 for repeat violations within 366 days, plus potential criminal prosecution under the code enforcement chapters.
