Full Breakdown
Moore County Code § 10-41(b)(2) lists "the sounding of any horn, whistle or signal device on any automobile, motorcycle, bus, or other vehicle or railroad train, except as a danger signal or as required by law, so as to create any unreasonable, loud, raucous, disturbing or unnecessary sound" as unlawful noise, and extends the same rule to "the sounding of such devices whether mounted on a vehicle or not, intermittently or continuously, for a period in excess of 30 seconds," language broad enough to reach a vehicle alarm cycling on and off in a driveway or parking lot.
" Read together, a car alarm that trips briefly is not itself a violation, but one left sounding past the 30-second threshold in the general rule, or a vehicle burglar alarm still blaring 30 minutes after the owner has been reached, exposes the owner to citation by the Moore County Sheriff, the agency Sec. 10-44(d) charges with enforcing this article.
Violations & Fines
Sec. 10-44 makes any violation of the noise article a Class 3 misdemeanor, fined $100.00 to $500.00, and separately exposes the owner to a $200.00 civil penalty payable to the Sheriff within ten calendar days, rising by $300.00 if the county has to file a civil debt action to collect. The Sheriff may instead start with a warning citation ordering the alarm silenced immediately.
