Sparks, NV Noise Ordinances: Vehicle Noise (2026)

200 requires every motor vehicle operated on a Sparks street, highway, or public place to have a 'good and sufficient muffler properly attached,' and makes it unlawful to operate a vehicle whose exhaust bypasses the muffler or is ejected toward the street surface. 215, added by Ordinance 2442 in September 2010, separately targets amplified sound: it is unlawful for anyone parked or operating a motor vehicle on a highway, street, or alley to create or allow noise from an electronic amplification device, defined to include radios, stereos, tape and CD/DVD players, or any device amplifying pre-recorded music, voices, words, or data, that is plainly audible to a person with normal hearing from 25 feet or more away.

'Noise' under this section covers music, words, other sounds, or sounds a listener perceives as vibration or concussion. The 25-foot amplified-sound rule does not apply to authorized emergency vehicles or to emergency and anti-theft alarms. Together the three sections give Sparks Police two independent enforcement tools: an equipment-based muffler standard and a listener-distance-based stereo standard, so a citation can issue for either a defective exhaust system or an audible stereo, without needing a decibel meter for the stereo violation.
