Hawaii Work Zone Laws

How Hawaii handles work zones

Hawaii sets a flat $250 fine for speeding in a construction area, plus up to a $100 trauma-fund surcharge (HRS 291C-104). It's not a doubling, and the reduced limit binds whenever it's posted, no worker required. The handheld-device ban gets stricter here too: the $300 fine rises to $400 in a construction area (HRS 291C-137). Work zones use flaggers and police; ignoring an officer directing traffic is a petty misdemeanor (HRS 291C-23).

Speed, fines, phone, and the flagger

• Speed rule: Obey the posted construction-area limit set by the state or county (HRS 291C-104). The reduced limit applies whenever it's posted; the statute doesn't require a worker in sight. Go 30 mph or more over and it escalates to a separate excessive-speeding charge (HRS 291C-105).
• Fine multiplier: $250 flat fine for speeding in a construction area, plus up to a $100 trauma-fund surcharge (HRS 291C-104). Hawaii sets a fixed elevated fine, not a doubling, and it applies while the reduced limit is posted.
• Phone in a work zone: Restricted — put it down
• Flagger authority: Obey the flagger and the officer. Work-zone control uses flaggers and police, and willfully ignoring an officer directing traffic is a petty misdemeanor (HRS 291C-23); a flagger's paddle stands as a traffic-control device (HRS 291C-31).
• Base fine: $250 for construction-area speeding, plus up to a $100 trauma-system surcharge (HRS 291C-104).
