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

Modoc County does not have a residential commercial-vehicle parking ban (no weight or size limit on parking a truck near homes) in its code. It does control where commercial trucks travel. Modoc County Code Chapter 10.18 (Truck Terminal Access Routes) requires the owner or operator of a freight terminal - a facility where freight is consolidated, loaded, or offloaded, or where vehicles are regularly maintained or stored - to apply to the county road commissioner for route clearance and signing (Sections 10.18.010-10.18.020). Applications must show terminal location, preferred and alternate routes, adequacy of entries, exits, and parking, and any road geometry concerns; accepted routes are submitted to Caltrans for review (Section 10.18.040). Approval may be revoked if a designated terminal route performs unsatisfactorily, and the applicant may bear signing and analysis costs (Sections 10.18.050-10.18.060). Separately, Chapter 10.16 makes it unlawful to operate any vehicle with lugs, cleats, gougers, or other protruding implements that can damage paved or oiled county highways or wooden bridges, though standard metal tire studs are exempt. General commercial-vehicle stopping and parking on county roads otherwise follows the California Vehicle Code.
