Summary
Horns, sirens and signal devices that produce loud, brash or harassing noise are a declared nuisance in unincorporated Oconee County whether they're mounted on a vehicle or not. A car alarm that keeps blaring after it goes off can draw a citation under the same noise ordinance that covers stereos and mufflers.
Any noise of such character, intensity, or duration which substantially interferes with the comfortable enjoyment of persons of ordinary sensibilities occupying, owning, or controlling nearby properties or of persons making use of public properties for their intended purposes, is hereby declared to be unlawful and to be a nuisance, and is prohibited. ... Nuisance noises shall include, but not be limited to, the use or operation of the following instruments, devices, or pieces of equipment when operated in the manner prohibited by section 12-32: ... (5)Horns, sirens, and signal devices using loud, brash, or harassing noises, whether on vehicles or otherwise.
Full Breakdown
Sec. 12-34(a)(5) lists horns, sirens, and signal devices using loud, brash, or harassing noises, whether on vehicles or otherwise, among the specific equipment the county presumes creates the nuisance prohibited by Sec. 12-32. That reaches a vehicle alarm sounding off in a way that disturbs nearby residents, and it is not limited to any particular location or time of day. Sec. 12-35(3) carves out a narrow exemption for horns, sirens and alarms used with authorized emergency vehicles or as legitimate safety devices to warn of danger or crime, but that exemption specifically does not extend to a burglar alarm that malfunctions, cross-referencing the separate rule in Sec.
12-34(b)(2) requiring an audible alarm system to shut off within 20 minutes of activation when it cannot be readily silenced manually; each activation beyond 20 minutes is its own separate offense. Sec. 12-33 lets the county cite a violation without any decibel measurement where three or more independent complaints are registered, or one complaint plus a responding officer's own observation, and Sec. 12-36 has the officer weigh the noise's volume, intensity and whether it is usual for the surrounding area.
Violations & Fines
A violation of Sec. 12-34(a)(5) is a misdemeanor under the general penalty in Sec. 1-7, with fines and jail time capped at the magistrate court's jurisdictional limits, and each day or each separate activation is its own offense. Officers may warn first under Sec. 12-40, or cite and arrest immediately if the circumstances call for it.
