Summary
Novi caps amplified sound from vehicles, including motorcycles and mopeds, at fifty feet: under City Code § 22-99, no one may operate an electronically amplified sound system in or on a parked or moving vehicle so it's plainly audible beyond that distance, unless the city council has granted a specific permit. The vehicle's registered owner is presumed to be the operator for enforcement purposes.
(a)No person operating or in control of a parked or moving vehicle, including motorcycles and mopeds, shall operate or permit the operation of an electronically amplified sound system in or on the vehicle so as to produce sound that is plainly audible more than fifty (50) feet from the vehicle, except when a specific permit is first granted by the city council. The term "plainly audible" shall mean any sound that can be detected by a person using his or her unaided hearing faculties. ... (b)In a prosecution under this section, proof that the particular motor vehicle described in the citation was used in the violation together with proof that the defendant named in the citation was the owner of the motor vehicle at the time of the violation constitutes in evidence a presumption that the registered owner of the motor vehicle was the person who operated or controlled the motor vehicle when the noise violation occurred.
Full Breakdown
Section 22-99 governs amplified sound equipment mounted in or on vehicles, reaching motorcycles and mopeds as well as cars and trucks, whether parked or moving. The core rule in subsection (a) bans operating an electronically amplified sound system so that it produces sound "plainly audible" more than 50 feet from the vehicle, with "plainly audible" meaning detectable by unaided hearing, a lower bar than a decibel meter reading. The only lawful way around the limit is a specific permit granted in advance by the city council.
Subsection (b) creates an enforcement shortcut: proof that a particular vehicle was used in the violation, combined with proof that a named defendant owned that vehicle at the time, creates a legal presumption that the registered owner was the person operating or controlling the vehicle when the noise occurred, shifting the practical burden onto the owner to rebut it. Subsection (c) lays out how the city council permit works for non-commercial use: the applicant must show the message can't be effectively communicated to the public any other way, and the equipment cannot be used in residential areas between 10:00 p.m. and 7:00 a.m. even under a granted permit.
Because § 22-99 doesn't set its own fine, a violation falls back on the citywide default penalty in § 1-11: a misdemeanor punishable by up to 90 days in jail and/or a $500 fine, charged separately for each day of violation.
Violations & Fines
Violating § 22-99's 50-foot audibility limit is a misdemeanor under the citywide default in § 1-11, punishable by up to 90 days in jail and/or a $500 fine, with each day charged separately. Because the registered owner is presumed to be the operator under § 22-99(b), the ticket typically follows the vehicle's registration even if someone else was driving.
