Full Breakdown
PMC § 9.18.020(A) makes the unnecessary or unreasonable use of horns, signaling devices, and similar devices on cars, motorcycles, and motor-driven cycles a noise violation. Subsection (B) targets sound equipment: operating a radio, loudspeaker, sound amplifier, or similar device so it disturbs the peace, quiet, or comfort of a reasonable person anywhere in the City is prohibited outright, with exceptions only for licensed parades, law enforcement and emergency personnel on duty, and anyone specifically permitted by the City to make noise in a public park or facility.
Two "prima facie" triggers make enforcement concrete: operating any sound device, including a stereo, television, drum, or musical instrument, between 10:00 p.m. and 8:00 a.m. so it's plainly audible from 50 feet away, or operating any sound amplifier connected to a radio, stereo, CD player, or similar device so it's plainly audible from 50 feet and causes a person at that distance to feel the vibration. Any officer authorized to enforce Chapter 9.18 who finds evidence of a prima facie violation can confiscate and impound the amplifying or transmitting components as evidence under § 9.18.020(B)(3). Separately, § 9.18.020(D) bans jake brakes, meaning compression-release engine brakes and any method of using engine compression to slow a vehicle, anywhere within Palmdale, with no time-of-day limitation.
Violations & Fines
