Full Breakdown
Section 154-7 of the West Haven Code sets three rules for vehicle noise in the City of West Haven. First, every motor vehicle operated within the city limits is subject to the noise standards and decibel levels in Sections 14-80a-1a through 14-80a-10a of the Regulations of Connecticut State Agencies. Second, no sound-amplifying device on or within a motor vehicle can emit noise above the levels specified in § 154-5. Those levels are measured in dBA with a sound-level meter. A residential emitter is held to 62 dBA into an industrial receptor, 55 dBA into a commercial receptor, 55 dBA into a residential receptor by day and 45 dBA into a residential receptor at night. A commercial emitter is held to 62, 62, 55 and 45 dBA in that order, and an industrial emitter to 70, 66, 61 and 51 dBA. Daytime hours run from 7:00 a.m. to 10:00 p.m. and nighttime hours run from 10:01 p.m. to 6:59 a.m. Readings are taken about one foot beyond the boundary of the emitter's premises, and the chapter defines those premises to include contiguous publicly dedicated street and highway rights-of-way.
Two rules in § 154-6 reach vehicles directly. No person can sound a horn or other audible signal device of a motor vehicle unless it is necessary as a warning to prevent or avoid a traffic accident. A mobile source engine cannot run more than three consecutive minutes while not in motion, with exceptions for traffic or mechanical trouble beyond the operator's control, equipment needed for the vehicle's intended use, reaching the manufacturer's recommended operating temperature, outdoor temperature below 20° F, and repairs.
Section 154-7C gives enforcement of the motor vehicle section to the Chief of Police and designated subordinates. Section 154-5E(10) exempts mobile sources such as automobiles and trucks from the general standards but states that motor vehicles remain subject to § 154-7. A person living or doing business in West Haven can ask the Director of Health for a variance under § 154-11, limited to provisions more stringent than the state Department of Environmental Protection noise regulations.
Violations & Fines
A violation of Chapter 154 carries a fine not to exceed $99, and each day the violation continues is a separate violation under § 154-10. Separately, refusing the Director of Health access under a court warrant, or hindering an authorized person taking noise measurements, is its own offense under § 154-9. A violator can also be billed the city's overtime cost when after-hours measurements confirm a violation.
