Mount Prospect, IL Noise from Specific Sources: Delivery Truck Noise (2026)

The Village Board placed this overnight truck rule inside the nuisance article of the Village Code, at § 23.1403.1. It reaches only the residential districts named in the text: R-X, R-1, R-A, R-2, R-3 and R-4. Inside those districts, from 7:00 P.M. until 7:00 A.M., three separate truck activities are unlawful. The first is driving a commercial vehicle to a specific address in the Village for the purpose of loading or unloading it at that address. The second is loading or unloading a commercial vehicle, regardless of who is doing the work. The third is running the engine or the refrigeration unit of a parked commercial vehicle. Residential moving vans are carved out of the first two prohibitions, but the engine and refrigeration unit prohibition prints no moving van exception.

The definition of the regulated vehicle is broad. A commercial vehicle means any vehicle other than a school bus or a first division vehicle as defined by the Illinois vehicle code, so the test is what the vehicle is, not whether a business owns it or what it carries.

The code builds in one narrow safety valve for second division vehicles. A person can load or unload one at times otherwise prohibited, but not more than twice in any twelve (12) month period, and only after giving the police department at least twelve (12) hours' advance notification. The section also does not apply to snow removal, to municipal operations, or to bona fide emergency home repairs.

Because the trigger is the residential zoning district, the section names no business or industrial districts, and a delivery to a commercial address falls outside it. Separately, § 23.1403 H of the nuisance article declares any offensive noise that disturbs the peace or quiet of the neighborhood a nuisance, and that provision is a different rule from the truck restriction. Residents who watch a refrigerated truck idle on a residential street overnight are looking at a violation of the engine and refrigeration unit clause, not just a courtesy issue.
