Off-Road Use: Registration Requirements

In Hawaii, dirt bikes used exclusively off-road are not required to be registered. However, to ride on designated off-highway vehicle (OHV) trails, riders must obtain an OHV permit.

OHV Permit Details:

  • Required for Non-Licensed Vehicles: All non-licensed vehicles, including dirt bikes, ATVs, and side-by-sides, must have an OHV permit to operate on designated trails.

  • Designated Riding Areas: Permits are valid for specific OHV areas such as:

    • Hawai‘i Island:
      • Upper Waiākea ATV & Dirt Bike Park
      • Mauna Kea ATV & Dirt Bike Riding Area

    • O‘ahu:
      • Kahuku Motocross Park

Helmet and Eye Protection:

  • Under 18: Operators and passengers under 18 are required to wear a DOT-approved helmet with a chin strap when operating or riding on a motorcycle.

  • All Riders: Eye protection is recommended for all riders, regardless of age.

Age Restrictions:

  • Under 16: Individuals under 16 years of age are prohibited from operating adult-sized ATVs.

Operation on Public Roads:

  • Operating dirt bikes on public streets, roads, or highways is prohibited unless the bike has been modified to meet street-legal requirements and is properly registered and insured.

Lighting Requirements:

  • If operating during low-light conditions, the dirt bike must be equipped with a functioning headlamp and taillamp.
