Summary
Maple Grove prohibits idling or testing a vehicle engine loudly enough to be plainly audible at the property line or 50 feet away, tying the idling rule to the city's general noise standard rather than a fixed time limit.
Operating or allowing or permitting the operation of any motor vehicle or any auxiliary equipment attached to such vehicle to idle or test any internal combustion engine in such a manner as to be plainly audible as stated in section 20-139.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 6 Update 1).
Full Breakdown
Maple Grove City Code § 20-141(7) makes it unlawful to operate or allow a motor vehicle or attached auxiliary equipment to idle, or to test an internal combustion engine, in a way that is "plainly audible" under § 20-139, meaning audible at the boundary of the property where the vehicle sits or 50 feet from the source. Unlike some cities' flat idling-minute caps, Maple Grove regulates idling through this noise-audibility trigger rather than a stopwatch limit. It sits within the noise chapter's motor-vehicle provisions and carries the code's general misdemeanor penalty.
Violations & Fines
Letting a vehicle or its equipment idle loudly enough to be heard at the property line or 50 feet away violates § 20-141(7) and § 20-139, punishable as a misdemeanor.
