California Air Resources Board limits commercial diesel idling to 5 minutes statewide, enforced aggressively in San Bernardino County warehouse hubs like Fontana, Ontario, and the Inland Empire. SCAQMD adds local enforcement in non-attainment basins.
CCR Title 13 section 2485 prohibits diesel-fueled commercial vehicles over 10,000 pounds from idling more than 5 minutes at any location. The Inland Empire suffers some of the worst air quality in the United States due to warehouse truck traffic from the ports of Long Beach and Los Angeles funneling through the Cajon Pass. South Coast Air Quality Management District inspectors issue citations at warehouse loading docks and truck stops. Drivers are personally liable in addition to fleet operators. Sleeper-berth exceptions apply but require documentation.
First violation carries a minimum 300 dollar civil penalty per occurrence. Repeat or fleet-wide violations escalate to thousands per truck and may trigger SCAQMD compliance orders.
