Colusa County, CA Parking Rules: Oversized Vehicle Parking (2026)

Colusa County's principal oversized-vehicle parking rule is Section 12A-34, which prohibits parking any truck, truck-tractor, trailer, semitrailer, or combination unit with a capacity exceeding 12,000 pounds (six tons) gross vehicle weight on any street signed 'no parking' by board resolution; the road commissioner posts the affected streets (Section 12A-34(c)). For road use rather than parking, Section 12-24 caps gross weight (including load) at 16,000 pounds on a 'partially improved county highway' — defined in Section 12-23 as any public county highway other than one paved with concrete, asphalt, or a hard surface at least four inches thick — with axle limits of 6,000 lb (single tires) and 10,000 lb (dual tires); the road commissioner may issue overweight movement permits under Sections 12-25 and 12-26. There is no separate county ordinance setting blanket residential-street limits on large RVs or campers; statewide, California Vehicle Code Section 22507.5 authorizes counties to restrict oversized and recreational vehicles, and the Zoning Code (Section 44-3.20) bars storing oversized vehicles, trailers, or campers in required parking spaces.
