Summary
Granville County bans sounding a car horn or vehicle signal device while the vehicle isn't moving, except as a genuine danger signal, anywhere in the unincorporated area. The same section bars unreasonably loud or harsh signal sounds and sounding any device for an unnecessary or unreasonable length of time, covering most car-alarm complaints under the county's general noise ordinance.
Sec. 26-31. - Unnecessary noise. (a)Subject to the provisions of this section, the creation of any unreasonably loud, disturbing and unnecessary noise is prohibited. ... (1)The sounding of any horn or signal device on any automobile, motorcycle, bus or other vehicle while not in motion, except as a danger signal, or if in motion only as a signal necessitated by traffic conditions; the creation by means of any such signal device of any unreasonably loud or harsh sound; and the sounding of such device for an unnecessary and unreasonable period of time;
Full Breakdown
Sec. 26-31(a) opens the county's noise article by declaring any unreasonably loud, disturbing, and unnecessary noise unlawful countywide. Subsection (b)(1) then specifically targets vehicle signal devices: sounding a horn or signal device on any automobile, motorcycle, bus, or other vehicle while it isn't in motion is unlawful except as a genuine danger signal, and even a moving vehicle may only sound a signal when traffic conditions require it. The subsection separately bars creating an unreasonably loud or harsh sound by means of any such signal device, and bars sounding a device for an unnecessary and unreasonable period of time, language broad enough to cover a car alarm that cycles repeatedly or blares for an extended stretch after triggering.
Chapter 26 doesn't define a maximum number of minutes or a decibel ceiling, so whether a particular alarm crosses the line is judged against subsection (a)'s character, intensity, and duration standard rather than a fixed number. The ordinance applies to any vehicle parked or stopped anywhere in the unincorporated county, including private driveways and lots, since the noise article carries no exemption for private property.
Violations & Fines
A car alarm or horn violation under Sec. 26-31(b)(1) is enforced through the Code's general penalty, Sec. 1-6: a civil citation is issued directing the violator to appear before the county finance officer within 15 days or pay by mail, and the violation must be corrected by the time the citation is paid or further citations follow. Each day the offense continues can draw a separate citation. Willful failure to pay an imposed civil penalty is a misdemeanor under G.S. 14-4, punishable by a fine of $500.00 or 30 days in jail, or both, with civil citations handling a first noise complaint in practice.
