Austin City Council weighs new traffic-code offense targeting unreasonable vehicle engine noise and vibration complaints

A proposal aimed at persistent neighborhood complaints

Austin is considering a targeted change to its traffic regulations that would create a new local offense for “unreasonable” vehicle engine noise, expanding the city’s tools to address complaints linked to loud exhaust and aggressive driving behavior.

The proposal was presented to the City Council’s Public Safety Committee on Feb. 2, 2026, as a draft ordinance that would add a new section—§ 12-1-36—to Chapter 12-1 of the City Code (Traffic Regulation and Administration). The measure is structured to allow enforcement through officer observation and defined factors, while also establishing an 85-decibel presumption after a warning.

What the draft ordinance would do

The draft language would prohibit a person from making, or causing to be made, “any loud or disturbing noise or vibration” from a motor vehicle’s exhaust that is “offensive to a person of ordinary sensibilities,” except through a muffler or other effective device.

It also lists driving and vehicle conditions that may produce a violation, including missing or faulty equipment, a vehicle in disrepair, and specific behaviors such as rapid upshifting or downshifting, racing or revving, and unnecessary bursts of acceleration in non-emergency situations.

• Creates a new city offense specific to vehicle engine noise and vibration.
• Defines a set of behaviors and conditions that may constitute “loud or disturbing” noise.
• Establishes an enforcement framework that relies on officer judgment guided by enumerated factors.

The draft text presumes a vehicle engine noise is “loud or disturbing” if it exceeds 85 decibels after the driver receives notice from a peace officer that the noise is a public nuisance.

How enforcement is framed

Rather than requiring a decibel reading in every instance, the ordinance would direct officers to consider multiple factors when determining whether the noise or vibration violates the standard. Those factors include the intensity of the noise, whether it is usual or unusual, background sound levels, proximity to residences, time of day, duration, and whether it is recurrent, intermittent, or consistent.

The text anticipates judgment-based enforcement, explicitly stating that an officer “may be required to exercise judgment” and specifying the considerations that should inform that judgment.

How this fits within Austin’s broader noise framework

Austin already regulates several categories of noise through Title 9 of the City Code, including restrictions tied to amplified sound, certain late-night activity, and vehicle sound equipment audible at a specified distance. Separately, city boards have recently discussed enforcement coordination and transparency around sound-related regulation, including calls for improved cross-department communication and better public-facing data about complaints and permits.

What happens next

The draft ordinance is not yet shown with an effective date and would require City Council action to become law. The Public Safety Committee briefing marked an early step in the legislative process; further committee discussion and a full council vote would be needed before any new offense could take effect.
