Full Breakdown
Greeley's noise code treats a vehicle horn or 'audible signaling device', the same category a car alarm falls under, as unlawful to sound except as a genuine danger warning (§12-327), and separately bars sounding one for any 'unnecessary and unreasonable period of time' (§12-328). There is no fixed minute cap; Greeley Police judge reasonableness case by case on a complaint. No ordinance is written specifically for factory or aftermarket car alarms, this general horn/signaling-device rule is what covers them. The Municipal Code is current through Ord. No. 16, 2026, adopted 4-21-2026 (Supp. No. 6).
Violations & Fines
No fixed fine is set in the horn/signaling-device sections themselves; violations are enforced as misdemeanor infractions under the Code's general penalty provisions (Title 1, Ch. 9), complaint-driven by Greeley Police.
