Wyoming, MI Noise from Specific Sources: Delivery Truck Noise (2026)

Sec. 30-102(6) of the Wyoming, Michigan Code of Ordinances targets stationary heavy-vehicle idling rather than the act of delivering itself. It bars operating, or allowing operation of, the motor of any vehicle weighing more than five tons, 10,000 pounds, for a consecutive period longer than two minutes while the vehicle sits stationary on private property within 150 feet of property devoted to residential use. Four exceptions apply: a vehicle or motor being used in the course of normal productive work; a vehicle used by a public utility, municipal department, commission or other governmental agency to provide essential services; vehicles standing in established bus turnarounds, terminals or storage yards while transporting passengers; and any vehicle standing inside a completely enclosed structure.

A delivery truck actively loading or unloading, which is normal productive work, is treated differently than one left idling at the curb past the two-minute mark. The same article separately bans altering a vehicle's exhaust or intake muffler under Sec. 30-102(11) unless the change reduces noise.
