Pharr, TX Noise Ordinances: Vehicle Noise (2026)

Pharr regulates vehicle sound through Sec. 86-103. Subsection (a)(7) targets car audio, and other parts of the same section address bass, exhaust and horns.

The stereo rule. It is unlawful for a person operating or controlling a motor vehicle to run a sound amplifier that is part of, or connected to, a radio, stereo receiver, compact disc player, cassette player, or other similar device so that it is audible at a distance of 30 or more feet from the source. Several parts of that wording matter. The rule applies "in either a public or private place within the city," so a private parking lot in Pharr is covered just like a public street. It reaches a person "operating or controlling" the vehicle, which is broader than driving it. The test is audibility at 30 feet from the source. Subsection (a)(7) sets no decibel reading and names no hours, so the quoted limit is not confined to nighttime.

Bass vibration. Sec. 86-103 also makes it unlawful to operate the system so that its bass vibration can be felt outside the vehicle. That gives Pharr a second test alongside the 30-foot audibility test, based on what a person outside the vehicle can feel.

Exhaust. Under Sec. 86-103(a)(4), engine exhaust may be discharged only through a properly installed muffler that prevents loud or explosive noise. A vehicle running without a functioning muffler does not meet that requirement.

Horns. The same section bars continued or frequent horn honking. The stated exception is use of the horn as a danger signal.

Enforcement reach. The city attorney enforces the noise article inside Pharr's city limits and for 5,000 feet beyond them. A vehicle just outside the boundary is still within reach of the article.
