Full Breakdown

City Code § 11-60(c)(1) restricts motor vehicle horns and warning or signaling devices, including car alarms, to the emergency situations they're designed for; setting one off outside a genuine emergency, including nuisance triggering from a parked car, is a noise disturbance violation. The police department enforces this section directly, and officers can cite the vehicle owner. Under § 11-59, a first violation carries a fine of $250 to $1,000, a second $500 to $2,500, and a third or later violation $1,000 to $5,000, with each day of continued violation counted as a separate offense.

Violations & Fines

First offense: $250-$1,000. Second: $500-$2,500. Third and later: $1,000-$5,000. Each day of a continuing violation counts as a separate offense; police enforce directly under § 11-60.
