Summary
Montgomery bans idling or leaving any motor vehicle running unattended for more than 15 minutes, treating the act as a public nuisance under the city's noise ordinance. The city says the rule targets air pollution, noise and vehicle theft, and violators face the same fine as other noise-code offenses.
(f)It is hereby declared a nuisance and shall be unlawful to idle or leave motor vehicles running for more than 15 minutes unattended. The purpose is to help with preventing environmental/air pollution, noise, and to prevent individuals from potentially being a victim of crime/theft.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 27).
Full Breakdown
Sec. " The rule was added to the noise division, Chapter 18, Division 2, by Ord. No. 64-2012, adopted October 16, 2012, alongside the division's other nuisance-noise provisions, and sits under the same enforcement structure as the division's other bans: no permit issued under Sec. 18-174 can authorize an act this section prohibits, so there is no way to get advance permission to leave a vehicle idling unattended past the 15-minute mark. Because the ban is keyed to "unattended" idling, it targets vehicles left running and out of the driver's control, whether parked on a street, driveway or lot, rather than a vehicle idling while someone remains at the wheel.
As with the rest of the noise division, Sec. 18-171 frames the underlying policy: unnecessary or unnatural noises detrimental to public health, comfort and safety are enacted for the public interest, and the Montgomery Police Department enforces the idling ban the same way it enforces the division's stereo, lawn-equipment and bass-noise rules.
Violations & Fines
Sec. 18-172 applies the noise division's standard penalty to an idling violation: a fine of up to $500.00, with each day the vehicle is left running unattended past 15 minutes on a separate occasion counted as its own offense against the city.
