California Air Resources Board regulations limit diesel-fueled commercial vehicle idling to five minutes statewide, applying countywide in Orange County including ports, distribution centers, and school drop-off zones.
CARB's Airborne Toxic Control Measure restricts diesel-powered commercial vehicles over 10,000 pounds from idling more than five consecutive minutes at any location. School zones, residential areas within 100 feet of homes, and California school buses face stricter limits. Orange County does not add a county-specific ordinance in unincorporated areas but coordinates with CARB enforcement at the John Wayne Airport cargo apron and at major logistics hubs along the I-5 and SR-91 freight corridors. Drivers must shut engines off rather than rely on factory idle when stopped for loading or rest.
CARB issues citations starting around $300 per violation; repeat offenses escalate. Fleets face additional penalties tied to compliance audits.
