Rockdale County, GA Noise Ordinances: Vehicle Noise (2026)

Section 42-1(b) targets musical equipment operated in or on a motor vehicle, defined broadly at subsection (a) as any vehicle propelled or drawn on land by an engine or motor, on-road or off-road. The violation turns on one measurable fact: whether the sound is "plainly audible at a distance of 100 feet from the point of origin," and the same subsection specifies that words or phrases need not be discernible for the standard to be met, only that a listener 100 feet away can tell music, speech or sound is being produced.

Two categories of vehicle are carved out: law enforcement vehicles, and motor vehicles used for business or political purposes that use sound-making devices in the normal course of conducting that business, such as a truck with a mounted speaker system for an announced event. The 100-foot test is distinct from the horn provision in subsection (g), which instead measures a "sustained period" of 15 continuous minutes or 30 intermittent minutes, and from the residential and commercial zone rules in subsections (d) through (f), which measure audibility from a property line rather than a fixed distance.

Traced to Code 1978, § 9-1004 and amended by Ord. No. 2007-21 (2007) and Ord. No. 0-2010-05 (2010), the vehicle-noise rule is enforced on the road by Rockdale County Sheriff's Office deputies, who can measure the 100 feet by pacing or estimation at the traffic stop.
