Trinity County, CA Parking Rules: Commercial Vehicle Restrictions (2026)

Trinity County's Title 10 does not include a residential commercial-vehicle parking ban of the kind found in dense cities; the word 'commercial' appears in Title 10 only in the abandoned-vehicle exemption. Where a commercial vehicle parks on a county road, the California Vehicle Code applies: CVC §22500 governs unlawful stopping and parking, and CVC Division 15 (Size, Weight and Load) sets statewide axle and gross-weight limits. The County does regulate heavy trucks through its road code. Trinity County Code §10.56.010 requires anyone hauling loads in excess of state maximum weight limits on county roads to obtain a permit/agreement from the county road department, with protective restrictions and a financial contribution, and limits such hauls to 75 miles. Posted county bridge limits also apply: Code §10.28.010 caps gross weight at 14,000 pounds on the Old Lewiston Bridge (County Road 212) and on Rush Creek Drive (County Road 275). On Court Street in Weaverville, §10.48.035 specifically bars trucks, pickup trucks, vans, motor carriers and buses from the described parking areas. Home-based commercial-vehicle storage is addressed through Title 17 zoning rather than a traffic ordinance.
