Full Breakdown
Cook County Code § 82-92 bars standing or parking any truck, tractor, semi-trailer, recreational vehicle over 22 feet, motor home, or bus on a residential street beyond the time needed to load or unload. Separately, heavy trucks over 8,000 pounds empty weight, commercial vehicles, trailers, and other heavy equipment may not stop or park within 200 feet of a residential-zoned lot of record, except while actively loading, for up to two hours, where signs post the restriction. The section applies on County highways in unincorporated areas, or in municipalities that have entered an intergovernmental enforcement agreement with the County: it does not reach Chicago.
Violations & Fines
Violating either the residential-street loading-time limit or the 200-foot buffer around a residential lot draws a $50 fine per offense under § 82-92(e); the buffer restriction only applies where warning signs have been posted.
