Truck-specific rules and quirks
- 60 mph on Interstate H-1 (Kapolei to Waipahu) and H-3 is the highest limit in the state. Hawaii sets limits by county ordinance and DOT posting, not by a statewide number (HRS 291C-102).
What a speeding ticket costs
Excessive speeding is criminal in Hawaii: 30 mph over the limit, or 80 mph or more on any road, is a petty misdemeanor (HRS 291C-105). A first offense runs $500 to $1,000, a 30-day license suspension, and possible jail. 80+ is criminal no matter the posted limit, so a loaded downhill run can cross that line.
