Bicycle Highway-Access Laws in Hawaii

The rule
Bicycles are prohibited on Interstate highways in Hawaii. Bicycles and pedestrians are prohibited on Hawaii's Interstate H-1, H-2, H-3, and H-201 freeways under HRS § 291C-101 and HDOT signage. The Interstate corridors on Oahu are urban controlled-access expressways; all are signed prohibited at on-ramps. Conventional state and county highways across the islands are open by default.
What this means in practice
Stick to surface streets, US routes, state highways, and dedicated paths. If your route in Hawaii appears to use an Interstate, plan a detour before you start.
Bigger roads, longer rides
Size a road bike for shoulders, group rides, and rural highways
Highway-access and group-riding rules favour riders who can hold a straight line at speed. Start with a frame that fits.
