Fontana, CA Parking Rules: Commercial Vehicle Restrictions (2026)

Fontana is an Inland Empire logistics hub with heavy truck traffic, and the city enforces commercial-vehicle parking rules closely. FMC Title 10 prohibits commercial vehicles exceeding 10,000 pounds GVWR (Gross Vehicle Weight Rating) and vehicles over a specified length (often 22 feet) from parking overnight on residential streets. Semi-truck tractors, trailers, dump trucks, and construction equipment are excluded from residential street parking except for brief active loading or unloading at a specific address, typically under 30 minutes. Drivers who live in Fontana and operate a truck commercially must park the vehicle at an employer yard, a commercial lot, or an industrially zoned property. California Vehicle Code 22507 allows cities to post commercial-vehicle restrictions on specific streets, and Fontana has adopted such restrictions in most residential neighborhoods. On truck routes designated in FMC Title 10, through-trucks are limited to specific arterials (such as Sierra Avenue, Foothill Boulevard, Slover Avenue, and Valley Boulevard near I-10 and I-15). Violations along truck routes or in restricted residential zones generate heavy citations. Fontana also enforces idling limits consistent with California Air Resources Board rules (5-minute idle limit for diesel trucks).
