Hoover, AL Noise Ordinances: Vehicle Noise (2026)

Section 11-153, in Chapter 11, Article VII (Disorderly Conduct and Indecency), is Hoover's general noise ordinance, enacted to protect, preserve and promote the health, safety, welfare and peace and quiet of the city's citizens. Subsection (b)(4) targets vehicle and machine noise directly: it is unlawful to discharge the exhaust of any machine, stationary internal combustion engine or motor vehicle except through a muffler or other noise abatement device, and operating that machine or vehicle loud enough to be heard 50 feet from the building, structure or premises where it sits is prima facie evidence of a violation.

The same section separately bans sound equipment such as radios, stereos and PA systems that disturb the quiet of a residence or a business under (b)(1)-(2), and bans sounding a horn on a stopped vehicle except as a danger signal under (b)(3). Five exceptions cover public-address systems at public facilities; emergency, police, fire and warning devices; city-authorized special events, including Hoover Metropolitan Complex activities; a properly muffled generator or lawn-maintenance engine; and emergency public-service work. Anyone creating the noise, or anyone who permits it from property under their care, custody or control, is presumed responsible.

Enforcement runs through the Hoover Police Department and municipal court. A defendant may plead guilty and pay the schedule fine any time before trial: $50 for a first offense, $100 for a second, and a mandatory court appearance for a third within the same enforcement period.
