Full Breakdown
DeSoto's noise-nuisance article enforces vehicle sound through a nuisance standard rather than a dBA reading. Section 8.402 declares it a violation to sound any horn 'except as a danger signal as required by state law,' to play a car radio, compact disc, or cassette 'with such volume as to disturb the peace, quiet, comfort, or repose of persons of ordinary sensibilities,' to operate a vehicle 'so out of repair' that it squeals tires or grinds, and to discharge engine exhaust except through a muffler that effectively prevents loud or explosive noises. DeSoto Police enforce it, and Municipal Court fines reach $500 per offense.
Violations & Fines
Officers cite the driver; each offense is a fine up to $500 in DeSoto Municipal Court. A gutted or missing muffler, a booming stereo audible over ordinary sensibilities, and squealing tires each count as separate violations.
