Anza FAQ
Who enforces loud-exhaust complaints in unincorporated Riverside County?
On-road vehicle exhaust noise is a California Vehicle Code matter (sections 27150 and 27151), enforced by law enforcement such as the Sheriff or CHP, because the county's Noise Element states that on-road motor vehicle noise is preempted from local regulation.
Does Riverside County set its own vehicle noise limits?
Yes, but only for off-highway (off-road) vehicles and vehicle sound systems. Ordinance No. 847 caps off-highway vehicles at 96 dBA (1986 or newer) or 101 dBA (older) and limits vehicle stereos so they are not audible inside a home between 10 p.m. and 8 a.m. or beyond 100 feet at other times.
Menifee FAQ
Can I get cited for a loud car stereo in Menifee?
Yes. A vehicle sound system audible inside any inhabited home between 10:00 p.m. and 8:00 a.m., or audible more than 100 feet from the vehicle at any other time, violates Development Code Section 9.210.060(F)(1).
Are dirt bikes and quads subject to noise limits in Menifee?
Yes. Off-highway vehicles must have a USDA-qualified spark arrester and a properly maintained muffler, and may not exceed 96 dBA (101 dBA for pre-1986 vehicles) measured at 20 inches from the tailpipe.
