Sanford, FL Noise from Specific Sources: Car Alarm Limits (2026)

Section 38-70(6) targets the sounding of any horn or signal device on a motor vehicle, language broad enough to reach a car alarm that repeatedly blares, when it runs for an unnecessary or unreasonable period of time, and separately bans directing a horn or signal at another person without a legitimate purpose for harassment. The neighboring provision, section 38-70(7), bars the use of any siren on a vehicle other than a police, fire, ambulance, or other emergency vehicle, reinforcing that non-emergency vehicle noise-making devices are tightly restricted citywide.

These prohibitions sit inside the article's specific-activities list in section 38-70, which is enforced the same way as the rest of the noise ordinance: a violation constitutes a noise disturbance under section 38-67, and section 38-66(11) separately governs amplified sound audible from within a vehicle's stereo, a related but distinct rule about in-car audio rather than horns and alarms. Sanford police and code enforcement officers must issue a written warning first under section 38-77, generally allowing immediate compliance and never more than five minutes before a citation can follow.
