Full Breakdown
Houston's Code of Ordinances splits vehicle noise into two separate offenses. Section 30-4 bans operating any motor vehicle so out of repair or overloaded that it creates loud, unreasonable grating, grinding, rattling, or squeaking sound - covering blown mufflers, bad exhausts, and rattling loads. Section 30-7 separately bans vehicle sound systems - car stereos, radios, speakers - that disturb neighbors' peace or are plainly audible from 50 feet away. Both apply regardless of the chapter's general decibel limits. Violating either section is a fine of up to $2,000 per hour under Section 30-17.
Violations & Fines
Operating a vehicle with a defective muffler or exhaust that creates loud grating, grinding or rattling; running a car stereo or speaker plainly audible 50 feet away or disturbing neighbors' peace.
