It is unlawful for any person to sound any horn or signaling device on an automobile, motorcycle or other vehicle on any street or public place of the city, except as a danger warning; to create by means of any such signaling device any unreasonably loud or harsh sound; to sound any such device for an unnecessary and unreasonable period of time; to use any signaling device except one operated by hand or electricity; to sound any horn, whistle or other device operated by engine exhaust; and to use any such signaling device when traffic is for any reason held up. ...

Full Breakdown
37(A) makes it unlawful to sound a horn or other signaling device on an automobile, motorcycle or other vehicle except as a danger warning; to create an unreasonably loud or harsh sound with such a device; to sound it for an unnecessary or unreasonable period; to use a signaling device other than one operated by hand or electricity; to sound a horn, whistle or device operated by engine exhaust; or to sound a signaling device merely because traffic is held up. Subsection (D) separately bans emitting exhaust into the open air from any motorboat or motor vehicle except through a muffler or other device that effectively prevents loud or explosive noises.
38(B) bars operating any motor-driven vehicle anywhere in the city in a manner causing that same discomfort or annoyance, though that subsection expressly excludes vehicles operated on a public highway, street or right-of-way. Both sections trace to Ordinance 1114, adopted in 1996.
