Full Breakdown

Carmel's noise ordinance applies to 'any machine, motor vehicle, device, or thing that produces or reproduces sound' (Sec. 6-158(a)), so a stationary or idling vehicle blasting sound can violate the local decibel/audibility limits. However, Sec. 6-158(b)(11) exempts 'those sounds associated with motor vehicles lawfully operating on City streets,' subject to the other provisions of the section and any other applicable law. The practical effect is that defective exhaust and modified vehicles on the road are handled under state law. Indiana Code 9-19-8-3 requires every motor vehicle to be equipped with a muffler in good working order and in constant operation to prevent excessive or unusual noise, and Indiana Code 9-19-8-4 prohibits muffler cutouts, bypasses, or similar devices.

Violations & Fines

Local stationary-vehicle noise is an infraction under Sec. 6-158(d) ($250 to $2,500 by offense). On-road exhaust and muffler defects are enforced under Indiana Code 9-19-8 as a Class C infraction.

Frequently Asked Questions

Does Carmel regulate loud car exhaust?
On-road exhaust noise is mostly a state matter. Sec. 6-158(b)(11) exempts sounds from vehicles lawfully operating on city streets, so loud-exhaust complaints are typically enforced under Indiana Code 9-19-8, which requires a working muffler and bans cutouts and bypasses.
What about a parked car blasting music?
That can fall under the local ordinance. Sec. 6-158(a) covers any motor vehicle that produces or reproduces sound, so amplified sound from a parked or idling vehicle audible 50 feet away can be cited as a noise infraction.
What is the penalty for a loud muffler in Indiana?
A violation of the muffler chapter, Indiana Code 9-19-8, is a Class C infraction. Carmel police can enforce state motor-vehicle equipment law on city streets.
