Summary
In the City of Noblesville, § 71.43 requires every motor vehicle to carry an effective, manufacturer-level muffler, banning loud exhaust modifications. The separate citywide noise ordinance, § 93.25, exempts ordinary vehicle sounds from its decibel limits but expressly carves out music and sound-system noise, so a blasting car stereo is not exempt.
No person shall operate a motor vehicle in the city without an effective muffler properly installed on such motor vehicle, nor shall any vehicle be operated in said city upon which is installed or being used any motor noise muffler device which fails to suppress the motor exhaust noise to a level equal to or below the noise volume achieved by the muffler equipment specified by the manufacturer of such motor vehicle. ... Subject to the other provisions of this section, and any other applicable law, rule or regulation, those sounds associated with motor vehicles lawfully operating on city streets. This does not include music or other sounds associated with a vehicle's sound system, including portable devices capable of emanating sounds that may be located within the vehicle;
Full Breakdown
Noblesville Code § 71.43, part of the Chapter 71 traffic rules the Common Council adopted under Ordinance 65-7-89 on August 14, 1989, makes it unlawful to drive a motor vehicle in the city without an effective, properly installed muffler, and separately unlawful to run any muffler device that lets exhaust noise exceed the level the vehicle's manufacturer built into the stock equipment. That is the citation an officer writes for a loud aftermarket exhaust or a disconnected muffler. Car stereo and sound-system noise is instead policed under the city's general noise ordinance, § 93.25.
Subsection (F)(9) exempts sounds associated with motor vehicles lawfully operating on city streets from the ordinance's decibel chart, but the same subsection specifically excludes music or other sounds associated with a vehicle's sound system, including portable devices, so a loud stereo is measured against the same limits as any other sound source: 60 dB(A) in commercial districts from 7:00 a.m. to 11:00 p.m. and 50 dB(A) overnight, 70 dB(A) anytime in industrial districts, and 55 dB(A) in residential districts by day and 50 dB(A) overnight.
Section 93.25(G) sets escalating fines for either kind of noise violation: up to $500 for a first offense in a commercial or industrial district or $250 in a residential district, doubling for a second offense within two years, up to $2,000 for a third, and up to $2,500 for a fourth or later offense regardless of district. The Noblesville Police Department writes both muffler and stereo-noise citations, and a violation is deemed to occur where the noise is generated or received.
Violations & Fines
A defective or modified muffler under § 71.43, or an oversized car stereo caught by § 93.25(F)(9)'s carve-out, exposes a driver to escalating fines under § 93.25(G): up to $500 (commercial/industrial) or $250 (residential) for a first offense, rising to $2,500 for a fourth offense within two years. The Noblesville Police Department cites and measures violations at the property line or 50 feet from the source.
