Vehicle Noise: Jurupa Valley vs Murrieta
How do vehicle noise rules compare between Jurupa Valley, CA and Murrieta, CA?
Jurupa Valley, CA
Riverside County
Vehicle exhaust and engine noise on public streets in Jurupa Valley is regulated almost entirely by California state law — not by Chapter 11.05. Cal. Vehicle Code §27150 requires every motor vehicle to have an adequate muffler in constant operation and prohibits cutouts/bypasses. Cal. Veh. Code §27151 caps modified-exhaust noise at 95 dBA (light vehicles, SAE test method). The Riverside County Sheriff (Jurupa Valley’s contract police agency) and the California Highway Patrol enforce these on public roads. The City’s Chapter 11.05 picks up vehicle activity on private property (truck yards, repair shops, idling, refrigeration units).

Jurupa Valley FAQ
Can the City ticket a loud motorcycle on the street?
Direct enforcement is by Riverside County Sheriff or CHP under Cal. Veh. Code §§27150 / 27151 — not under JVMC 11.05. The state limit for light vehicles is 95 dBA (SAE test).
What about a truck yard that runs reefers all night?
That’s a property-line noise issue — JVMC §11.05.040 and the §11.05.060 special-source standards apply. CARB’s 5-minute diesel idling rule (13 CCR §2485) is also separately enforceable.
Are sideshows / exhibition of speed enforced locally?
Cal. Veh. Code §23109 makes exhibition of speed a misdemeanor; the Sheriff enforces. The City’s noise ordinance does not separately address sideshows on public roads (state-preempted).
