Summary
Miami Beach bans unreasonably loud vehicle noise under City Code Sec. 46-152, covering horns sounded for unnecessary periods, exhausts discharged without an effective muffler, and vehicles so out of repair that they rattle or grind.

Full Breakdown
City Code Sec. 46-152 makes it unlawful to make, continue or cause any unreasonably loud, excessive, unnecessary or unusual noise, and lists specific violations. Subsection (a) bars sounding a horn or signaling device except as a danger warning, or for any unnecessary and unreasonable period. Subsection (e) requires every motor vehicle to discharge exhaust through a muffler or other device that effectively prevents unreasonably loud or explosive noise; vessel exhaust is instead enforced under Miami-Dade County Code Sec. S. Sec. 65. Subsection (f) separately targets vehicles, motorcycles, jet skis and dirt bikes that are so out of repair, loaded, or operated that they create unreasonably loud grating, grinding or rattling noise in a residential area.
A related provision, Sec. 46-161, addresses aftermarket car alarms: it is unlawful for an alarm system to emit a siren or horn audible at 100 feet for more than 15 minutes, intermittently or continuously. On a public street a violating vehicle is declared a public nuisance and a police officer may have it towed after giving the owner a chance to disconnect the alarm; on private property the owner or custodian instead faces a flat $50 fine, and code officers may enter the property without force to cite the vehicle.
Complaints under Sec. 46-152 go first to a code inspector, who may issue an oral or written warning before a formal notice of violation triggers escalating fines under Sec. 46-159, heard by a special magistrate if appealed within ten days.
Violations & Fines
A first Sec. 46-152 offense draws a $250 civil fine, rising to $1,500 for a second offense and $3,000 for a third within 12 months; a fourth offense adds business tax receipt or accessory-use restrictions limiting amplified sound. Sec. 46-161 car-alarm violations on private property carry a flat $50 fine, while a public-street violation lets police tow the vehicle. Appeals go to a special magistrate within ten days.
