Summary
Schaumburg's noise ordinance bars sounding any horn or signaling device on a vehicle for an unnecessary and unreasonable period of time, or in a way that creates an unreasonably loud or harsh sound, under Village Code § 97.02(A). That language covers a car alarm left blaring after it triggers, not just a driver leaning on the horn.
(A)Horns, Signaling Devices, Etc.: The sounding of any horn or signaling device on any automobile, motorcycle, or other vehicle on any street or public place of the village, except as a danger warning; the creation by means of any such signaling device of any unreasonably loud or harsh sound; and the sounding of any such device for any unnecessary and unreasonable period of time. The use of any signaling device except one operated by hand or electricity; the use of any horn, whistle, or other device operated by engine exhaust; and the use of any such signaling device when traffic is for any reason held up.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 56 Update 1 | Policy Manual: Supplement 20).

Violations & Fines
Letting a vehicle alarm or horn sound for an unreasonable period, or in an unreasonably loud or harsh manner, violates § 97.02(A) and carries the Village Code's general penalty under § 10.99: a fine of $100 to $50,000, with each day the noise continues treated as a separate offense. Because no fixed time limit is written into the section, an officer's judgment of what is 'unreasonable' drives whether a citation issues.
