Rialto, CA Parking Rules: Loading Zones (2026)

Rialto's city engineer designates loading zones under RMC 10.28.210, in business districts and in front of any building used for business or public assembly. No more than half the total curb length on any block can be reserved this way. Loading zones get yellow curb paint; passenger loading zones get white paint, so the color itself signals which rule applies before you read a sign.

Under RMC 10.28.220(B), a yellow zone bars stopping, standing or parking between 7 a.m. and 6 p.m. every day except Sundays and holidays, for anything other than loading or unloading. Passenger loading in that window cannot run past three minutes; materials loading cannot run past twenty minutes. Outside those hours, on Sundays, or on holidays, the yellow curb functions as regular parking.

RMC 10.28.230 narrows who gets the loading privilege. Materials loading applies only to commercial deliveries, including express, parcel post and U.S. mail pickups, and it never extends past the twenty-minute cap regardless of how much is being unloaded. Passenger loading covers personal baggage but stops at three minutes. A driver who parks in a yellow zone for any other reason, such as running into a store or leaving a vehicle unattended, is not covered by the loading exception and can be cited under RMC 10.28.240 for standing in a loading zone outside its permitted purpose. White passenger zones are governed the same way under RMC 10.28.250. Drivers who ignore posted yellow or white curb markings under RMC 10.28.220(D) are in violation regardless of intent.
