Full Breakdown
02. Subsection (D) targets vehicle horns and other audible signaling devices, the category a factory or aftermarket car alarm falls into when it sounds in a driveway, parking lot, or street in the unincorporated county. The rule allows only two exceptions: a genuine emergency, or a signal required by another law. A car alarm that goes off from a false trigger, is left unresolved, or is used outside those two situations is a violation once a deputy documents it. 02's broader prohibition, covering any noise that unreasonably disturbs a neighbor's peace, health, or enjoyment of property, still applies on top of the specific horn-and-alarm rule, so a persistent alarm can be charged under either provision.
07; citations are filed with the Lake Superior Court, County Division, and prosecuted by the County Attorney rather than a code-enforcement office. 05), an officer responding to a chronic alarm complaint can also cite excessive engine noise or a fixed alarm box separately. The rule applies only in unincorporated Lake County; Gary, Hammond, Crown Point, and the county's other cities and towns enforce their own municipal noise codes for alarms sounding inside their limits.
Violations & Fines
A violation of section 93.03(D) is punished under the chapter's general penalty in section 93.99, which routes to the county-wide fine schedule at section 10.99: not more than $2,500 for a first offense and not more than $7,500 for a second or later offense. Each day the horn or alarm sounds unlawfully counts as a separate offense, so an alarm left unaddressed over a weekend can generate multiple citations. Cases are prosecuted by the Lake County Attorney's office in Lake Superior Court, County Division.
