On county-maintained streets in unincorporated Los Angeles County, yellow curbs mark commercial loading zones reserved for vehicles actively loading goods, typically 7am to 6pm Monday through Saturday under Title 17.04.520. Passenger cars may not park during posted hours.
Title 17.04.520 of the LA County Code restricts yellow zones to commercial vehicles displaying valid commercial plates while actively loading or unloading freight. The standard restricted window is 7am to 6pm Monday through Saturday, though posted signs override defaults. Drivers must remain near the vehicle and complete loading within the time limit, often 20 minutes. Outside posted hours general parking rules apply and most cars may park. Businesses needing a yellow zone apply to LA County Public Works, pay an installation fee, and justify volume. The Sheriff's Department and Public Works enforcement officers issue citations. Private streets and incorporated-city streets are governed separately.
Parking a non-commercial vehicle in a yellow zone during posted hours is a parking violation under Title 17.04.520, fined approximately 73 dollars, with potential tow if blocking active loading operations.
