Summary

Bristol requires every motor vehicle operated in the city to meet the Connecticut DMV's maximum permissible vehicle noise regulation for muffler and engine noise, and separately caps any sound-amplifying device in or on a vehicle to the zone-based decibel table in section 15-21(b). Both rules sit in the noise chapter at section 15-21(d), and carry the chapter's standard escalating fine schedule.

(d)Motor vehicle noise.1.All motor vehicles operated within the limits of the City of Bristol shall be subject to the noise standards and decibel levels as set forth in the regulations of the State of Connecticut Department of Motor Vehicles, Section 14-80a-1a(a-1) entitled "Maximum Permissible Noise Levels For Vehicles."

Full Breakdown

Section 15-21(d)(1) adopts, by reference, the Connecticut Department of Motor Vehicles' regulation Section 14-80a-1a(a-1), titled 'Maximum Permissible Noise Levels For Vehicles,' as the noise-equipment standard for every motor vehicle operated within the city limits, covering excessive muffler and engine noise rather than restating a separate city decibel figure. Section 15-21(d)(2) then addresses amplified sound specifically: a vehicle's stereo or speaker system may not exceed the levels in the zone-based table at section 15-21(b), 62 dBA to an industrial or business receptor, 55 dBA to a residential receptor by day, and 45 dBA to a residential receptor at night.

Section 15-21(e) reaches recreational vehicles too, treating any noise above the section 15-21(b) table as unreasonably loud, and section 15-21(f) separately bars operating a recreational vehicle within 100 feet of a property line. Measurements are taken under the trained-operator, ANSI S1.4 procedure in section 15-20. Enforcement runs through the Bristol Police Department under section 15-24, whether on a resident's complaint or the department's own initiative, and anyone needing relief for a specific event can apply to the mayor for a variance under section 15-22 with 20 days' notice, with a failure to rule within five days counting as approval.

Violations & Fines

Violating the vehicle-noise standard is fined $90.00 for a first offense under section 15-25(a). A noise ticket that goes unresolved escalates to $200.00 for the second day and $400.00 for each day after that, and these remedies apply in addition to any penalty available under Connecticut law or the DMV's own noise regulation.

Frequently Asked Questions

Does Bristol have its own decibel limit for car mufflers?
No separate city number: section 15-21(d)(1) adopts the Connecticut DMV's own equipment regulation, Section 14-80a-1a(a-1), 'Maximum Permissible Noise Levels For Vehicles,' as the standard every motor vehicle operated in Bristol must meet for muffler and engine noise.
What about a loud vehicle stereo instead of the engine or muffler?
That's covered separately. Section 15-21(d)(2) caps sound-amplifying devices on or in a vehicle at the same zone-based table used for stationary noise sources, 55 dBA to a residential receptor by day and 45 dBA at night.
What's the fine for a vehicle noise violation in Bristol?
Section 15-25 fines a first violation $90.00, rising to $200.00 if the noise continues into a second day after a citation and $400.00 for every day after that.
