Las Cruces, NM Noise from Specific Sources: Low-Frequency Bass Limits (2026)

Section 19-132 of the Las Cruces Code of Ordinances targets the low-frequency thump from vehicle stereos, subwoofers and sound systems specifically, going further than the city's general noise rule in Section 19-121. It is unlawful to operate a sound amplifier connected to a radio, stereo receiver, CD player, cassette player or similar device in a motor vehicle, on public or private property, so that it is audible to another person or a police officer 30 feet or more away, or so that a person or officer can feel the vibration of the sound at that same 30-foot distance.

The vibration standard means a citation does not require the sound to be identifiable as music; a bass line felt through a car door or a nearby building's windows is enough. The section exempts authorized emergency vehicles, permitted political or business vehicles that use sound equipment in the normal course of business, horns and warning devices required by NMSA 1978, Section 66-7-6, and any amplified sound activity that already holds a temporary permit under Section 19-134. Violations fall under Section 19-133's penalty schedule for the noise division: a petty misdemeanor carrying a fine of not less than $100 and not more than $500, plus up to 90 days in jail at the court's discretion.

The $100 minimum fine cannot be suspended, deferred or taken under advisement, even though the judge may suspend any amount above that floor and any jail time. Where a complaint alleges a Section 19-132 violation, a guilty or no-contest plea must be entered to that specific violation; the case cannot be resolved through a plea to an unrelated charge instead.
