Las Cruces, NM Noise Ordinances: Vehicle Noise (2026)

Two separate sections of the Code of Ordinances noise division reach vehicle noise. Sec. 19-130 makes it a violation to use a defective muffler or other exhaust device designed to create and maintain loud and disturbing noise while an automobile, truck or motorcycle engine is running, if that noise disturbs the comfort or repose of a neighborhood. Sec. 19-132 separately targets amplified vehicle sound: 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, in a manner that is audible to another person or a police officer 30 feet or more from the source, or that causes a person or officer to feel the accompanying vibration at that distance.

Sec. 19-132(2) lists specific carve-outs from the stereo rule: authorized emergency vehicles as defined by NMSA 1978, §§ 66-1-4.1(D) and 66-7-6; permitted business or political vehicles that normally use sound-making devices in the course of business; horns or warning devices required under NMSA 1978, § 66-7-6; and amplified sound activities covered by a temporary permit issued under Sec. 19-134. A temporary permit under Sec. 19-134 lets the chief of police authorize noncompliant amplified sound for short events, issued free of charge for up to three consecutive days between 7:00 a.m. and midnight, after review of factors such as the activity's distance from residential zones and the number of amplification devices involved.

Both sections carry the same penalty under Sec. 19-133: a petty misdemeanor punished by a fine of not less than $100.00 nor more than $500.00 and up to 90 days in jail, with the $100.00 minimum fine barred from suspension, deferral or being taken under advisement. Violations may also be abated through a restraining order or injunction under Sec. 19-135.
