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

Unincorporated Stanislaus County does not publish a single oversized-vehicle parking ordinance; instead, Title 11 (Vehicles and Traffic) uses weight thresholds. Code Sec. 11.08.120 defines a 'truck' as any vehicle with a manufacturer's GVWR in excess of 10,101 pounds and prohibits parking such trucks on a list of signed county streets, drawing authority from Vehicle Code 22507, which lets local authorities restrict vehicles six feet or more in height within 100 feet of an intersection. Code Sec. 11.08.090 separately bars commercial vehicles of 10,000 lbs GVWR or more from parking on residential-district streets except for temporary delivery or permitted construction. For movement, Code Sec. 11.16.090 makes it unlawful for any commercial vehicle exceeding 14,000 pounds maximum gross weight to use listed county highways as a through route (authority Vehicle Code 21101(c)), and the county also restricts vehicles exceeding 24,000 pounds on other highways (Code Secs. 11.16.070-080). Oversized interstate trucks need special permits from Public Works (Chapter 11.18). For an oversized personal vehicle or RV, no county size cap applies on streets beyond the 72-hour rule and any posted truck or hourly restriction. Violations of Chapters 11.08 and 11.16 are infractions punishable under Vehicle Code 42001 (Code Sec. 11.32.010).
