Full Breakdown
Vehicle noise in Herndon is regulated through the Town Code and through adoption of Virginia motor vehicle laws by reference. Modified exhaust systems, straight pipes, cutouts, and muffler removal that cause a vehicle to emit sound louder than factory specification are prohibited under Virginia Code 46.2-1049, enforced by Herndon Police. Amplified car stereos that are plainly audible from 50 feet or more are subject to citation, particularly during nighttime quiet hours. Unnecessary engine racing, rapid acceleration, tire squealing, and burnouts violate both the noise ordinance and reckless driving statutes. Horn use is restricted to warning of immediate danger; prolonged or repeated horn honking to summon occupants, express frustration, or signal arrival is prohibited. Idling restrictions apply to diesel trucks and commercial vehicles that cannot idle more than a few minutes in residential areas. Motorcycles with aftermarket exhausts drawing repeated complaints may be subject to enhanced enforcement. Fines typically range from 50 to 250 dollars with equipment correction requirements.
