Twain Harte, CA Parking Rules: Commercial Vehicle Restrictions (2026)

Unincorporated Tuolumne County does not publish a standalone heavy-truck residential parking ordinance in Chapter 10.24. The chapter's commercial-vehicle controls are the general ones: Section 10.24.010 prohibits parking any vehicle - including trucks and trailers - on the county road system or rights-of-way 'in a manner which will obstruct vehicular traffic,' and Section 10.24.050(B) limits yellow-curb loading zones to no more than 20 minutes for loading or unloading freight 'unless otherwise allowed by the Board of Supervisors.' Buses engaged as common carriers, school buses, and taxicabs may stop to load or unload passengers in front of driveways (Section 10.24.040). For weight-based residential restrictions, the controlling authority is the state: California Vehicle Code Section 22507.5 lets local authorities, by ordinance adopted after a public hearing, prohibit or restrict parking of commercial vehicles with a manufacturer's gross vehicle weight rating of 10,000 pounds or more on residential streets, but only where signs are posted. Where the county has adopted no such resolution for a given road, a commercial vehicle may park subject to the 72-hour limit (Section 10.24.030) and the obstruction rule. General Chapter 10.24 violations carry a $35 penalty under Section 10.24.080.
