These county ordinances apply to unincorporated areas of Galveston County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

A motor vehicle shall be equipped with a muffler in good working condition that continually operates to prevent excessive or unusual noise. A person may not use a muffler cutout, bypass, or similar device on a motor vehicle.

Full Breakdown

Galveston County has no vehicle-noise ordinance, but state law applies everywhere in the county, incorporated or not. Texas Transportation Code Sec. 547.604 requires every motor vehicle to have a muffler in good working condition that continually operates to prevent excessive or unusual noise, and prohibits muffler cutouts or bypass devices; enforcement is by any peace officer. For car stereos, League City Code Sec. 42-34 bars operating a sound-amplification system in or on a vehicle so it is plainly audible 50 feet or more away, on public or private property. Galveston applies its Sec. 24-2 decibel caps and the state statute.

Violations & Fines

A muffler-cutout or excessive-noise stop is a traffic misdemeanor under state law. League City's plainly-audible car-stereo rule carries a $100-$1,000 fine (repeat $200-$2,000), each day a separate offense.
