California Air Resources Board limits heavy-duty diesel trucks to 5 minutes of idling and prohibits school-bus idling near schools. Los Angeles enforces additional residential idling rules, with fines escalating for repeat commercial offenders.
California Code of Regulations Title 13 §2485 caps idling for diesel trucks over 10,000 pounds at 5 minutes anywhere in the state, while §2480 prohibits school buses from idling within 100 feet of a school or while loading. South Coast AQMD Rule 1102 supplements these limits in the LA basin. Within Los Angeles, LAMC §80.27 adds a residential idle limit applied through LADOT and Bureau of Sanitation inspectors, with parallel enforcement against refuse trucks and tour coaches near hotels. Drivers must shut off engines while stopped, parked, or queuing, except for active loading, traffic, safety equipment, or sleeper-berth rest periods.
Civil penalties start at $100 for a first offense and rise to $300–$1,000 for repeats, with CARB able to assess up to $1,000 per day per violating heavy-duty vehicle.
