Riverside, CA Parking Rules: Commercial & Oversized Vehicles (2026)

160 prohibits parking any commercial vehicle or commercial non-self-propelled vehicle on a highway, street, or alley in a residential district, with only two narrow exceptions: while the vehicle is actively loading or unloading goods, wares or merchandise, or while it is parked in connection with, and in aid of, a valid commercial service being performed to or on a property in the same block where it's parked. 155 restricts any commercial vehicle rated 10,000 pounds gross vehicle weight or more, plus commercial trailers, semi-trailers, trailer coaches, trailer buses, and storage/pod containers regardless of weight, from parking on any street or alley citywide, not just residential districts, with exceptions for active pickups/deliveries, service calls, PUC-regulated buses, public-agency vehicles doing utility or highway work, emergency vehicles, streets designated for commercial parking, and pod containers holding a Public Works permit for up to a two-week stay.

Together the two sections mean a delivery truck may stop briefly on a residential block to make a delivery, but a contractor cannot leave a heavy truck, box trailer or storage pod parked overnight on a residential street without falling into one of the listed exceptions or securing a permit. "Commercial vehicle" is defined by reference to the vehicle types requiring a Class A, Class B, or endorsed Class C driver's license under the California Vehicle Code, while trailer terms track Vehicle Code §§ 550, 630, 635 and 636.
