Summary
Union County bars sounding a car horn, whistle or signal device "so as to create any unreasonable, loud or harsh sound" or for an unreasonable length of time, unless it is a danger signal or required by law. Vehicles must also keep manufacturer-standard mufflers to stay outside the noise ordinance.
Horns and signal devices. The sounding of any horn, whistle or signal device on any automobile, motorcycle, bus or other vehicle, except as a danger signal or as required by law, so as to create any unreasonable, loud or harsh sound, or the sounding of such device for an unreasonable period of time.
Full Breakdown
Sec. " The rule sits in Article II, Noise, alongside Sec. 26-20(2)'s ban on vehicle and pedestrian sound systems audible 50 feet away, so a car stereo and a car horn are each addressed separately in the same section. Mufflers get their own treatment through the exemption structure in Sec. 26-21(6), which excuses "noise resulting from motor vehicles in proper operating condition and properly equipped with the manufacturers' standard mufflers and noise-reducing equipment" from the noise ordinance. Read together, a vehicle running a straight-pipe or otherwise non-standard exhaust loses that exemption and falls back under the general unreasonably-loud-noise prohibition in Sec.
26-19, which reaches noise on public streets, at parking lots open to the public, and near occupied homes. S. S. 46, which separately protects sport shooting ranges from noise nuisance suits.
Violations & Fines
Sec. 26-22 makes a horn or exhaust-noise violation a Class 3 misdemeanor under G.S. 14-4, carrying up to a $200.00 fine and possible jail time at the court's discretion. Each day a violation continues after the county gives notice counts as a separate offense, and Union County can also seek an injunction or abatement order in civil court against the driver or the vehicle owner.
