Hawaii Truck Idling Law
Hawaii's air rule (HAR 11-60.1-34) bars idling at loading zones, parking and service areas, and terminals except for repairs, auxiliary equipment with no visible smoke, and up to 3 minutes for passenger loading or engine start-up and cool-down. Civil penalties run from $25 to $2,500 per day.
