Full Breakdown
Louisville Metro's Land Development Code sets operating-hour limits on loading and unloading activity within 100 feet of residentially zoned or residentially used property. Under LDC 4.1.6(B)(2), that nighttime loading ban also covers idling: heavy or medium trucks on site for loading or unloading purposes may not idle between 10:00 p.m. and 7:00 a.m., whether or not the loading has actually started. A separate LDC 4.2.66(D) provision bars any truck from idling while parked at a permitted heavy-truck storage lot in C-3 districts. Louisville Metro has no blanket idling-minutes law for ordinary passenger vehicles; home rule cities inside Jefferson County set their own rules.
Violations & Fines
Enforced as a zoning/land-use violation by Louisville Metro's planning and code enforcement staff; unresolved cases can go to the Code Enforcement Board for remedial orders and civil fines.
