Sioux City, IA Parking Rules: Commercial & Oversized Vehicles (2026)

In the same chapter that limits RV and trailer parking, Sioux City separately restricts heavy commercial vehicles. Any motor truck, truck tractor, road tractor, trailer, or semi-trailer with a licensed weight over five tons may not sit on a city street for more than one hour, except while actively loading or unloading. The rule goes further for city-owned lots: commercial trucks and trailers over five tons are barred entirely from off-street public parking facilities owned by the city, not just time-limited there. The restriction targets big rigs parking on ordinary city streets and lots rather than designated truck routes or private property.
