Ontario prohibits commercial vehicles over 10,000 pounds or 22 feet long from parking on residential streets overnight, and tractor-trailer staging is limited to zoned industrial yards under OMC Chapter 10.
Ontario is a major logistics hub adjacent to the Ontario International Airport and the BNSF San Bernardino Intermodal, so commercial vehicle parking is closely regulated. Under Ontario Municipal Code Chapter 10 and California Vehicle Code 22507.5, commercial vehicles exceeding 10,000 pounds gross vehicle weight rating or 22 feet in length may not be parked on residential streets between 10 PM and 6 AM, and short stops for active loading are limited to 20 minutes. Tractors, trailers, dollies, and shipping containers must be staged in zoned industrial or truck-terminal parcels; residential storage of semi-trailers is prohibited. Private driveway parking of a single pickup work truck is generally allowed. Box trucks, buses, and step vans must follow the same weight-based restrictions. Violations are cited by Ontario Police Traffic Division, with repeat offenders subject to tow under CVC 22651. Truck idling over 5 minutes is separately enforced under California Code of Regulations Title 13 Section 2485 (CARB anti-idling rule) throughout the South Coast Air Basin managed by SCAQMD.
