Who must wear a helmet in Hawaii, the penalties for not wearing one, and the eye-protection rules every rider should know.
Hawaii has a partial motorcycle helmet law. Any operator or passenger under 18 years of age must wear an approved safety helmet, securely fastened with a chin strap (Hawaii MOM, Equipment Requirements).
Riders 18 and older are not required by law to wear a helmet. Crash research is clear, though, that head and neck injuries account for a majority of serious and fatal motorcyclist injuries, and helmeted riders are three times more likely to survive head injuries — so a DOT-compliant helmet is strongly recommended on every ride (Hawaii MOM p.4-5).
Every operator under 18 and every passenger under 18 must wear an approved, properly fastened helmet. There is no exception for short trips or low speeds — most crashes happen on trips under five miles, at speeds below 30 mph (Hawaii MOM p.5).
Riders 18 and older may legally ride without a helmet in Hawaii. Because Hawaii also limits passengers — no passenger under age 7, and no passenger at all on a two-wheeled moped — a young child can never legally ride unhelmeted.
Riding without a required helmet — or carrying an under-18 passenger who is not wearing one — violates Hawaii's motorcycle equipment law and can bring a citation. Hawaii has no statewide DMV, and fine amounts are handled at the county level, so confirm the current penalty with your county Driver Licensing Office or the Hawaii Department of Transportation Motor Vehicle Safety Office.
Hawaii's eye-protection rule is broader than its helmet rule. Every operator and every passenger — at every age — must wear glasses, goggles or a face shield, unless the motorcycle is equipped with a windshield (Hawaii MOM, Equipment Requirements).
To be effective, eye or face shield protection must be free of scratches, resistant to penetration, give a clear view to either side, fasten securely so it does not blow off, and allow air through to reduce fogging. A face shield protects your whole face; goggles protect only your eyes; and tinted protection should not be worn when little light is available (Hawaii MOM p.6).
A legal motorcycle helmet must meet the U.S. Department of Transportation (DOT) FMVSS 218 standard. Look for the "DOT" certification label on the back. Helmets that meet stricter Snell or ECE standards offer additional protection. Avoid novelty helmets — they are not legal head protection.

Hawaii's Motorcycle Operator Manual does not publish a question count or passing score; the 25-question, 80%-to-pass figure shown here is a third-party practice format. As of December 24, 2025, a Basic RiderCourse is required before a motorcycle instruction permit is issued. Hawaii has no statewide DMV — licensing is handled by the four county Driver Licensing Offices.
