To ride legally in the islands, Hawaii moped laws require a valid driver’s license, annual county registration, a yearly safety inspection, and compliance with road rules that keep mopeds off freeways and sidewalks and inside marked bicycle lanes. Fines run up to $100 per violation, and impaired riders face the same DUI penalties as drivers of cars.
What Counts as a Moped
Hawaii defines a moped narrowly. Under Hawaii Revised Statutes § 291C-1, a moped is a two- or three-wheeled vehicle with a motor producing no more than two horsepower (1,492 watts). A combustion engine cannot exceed 50 cubic centimeters, top speed on a flat surface cannot exceed 30 miles per hour, and the drive system must be direct or automatic with no manual clutch or gear shifting.1Justia. Hawaii Code 291C-1 – Definitions
Anything above those thresholds is a motorcycle or motor scooter in the eyes of the state, which brings stricter requirements including a motorcycle license endorsement. Electric foot scooters are not mopeds under this definition.1Justia. Hawaii Code 291C-1 – Definitions
License and Age
You need a valid driver’s license to operate a moped on any public road. There is no separate moped endorsement; a standard driver’s license is enough.2Hawaii Department of Transportation. Motorcycles, Motor Scooters and Mopeds General Information
The statutory minimum age is 15. Hawaii Revised Statutes § 291C-195 prohibits anyone under 15 from operating a moped on any highway, street, roadway, or public property.3Justia. Hawaii Code 291C-195 – Driving of Mopeds In practice the effective age depends on when a rider can obtain a license or permit, and minors applying need written consent from a parent or legal guardian.4City and County of Honolulu. Motorcycle or Moped Drivers License Information
Visitors are not exempt. A tourist renting a moped must carry a valid driver’s license from home. Rental companies check for it, and most set their own minimum rental age at 18 even though the state allows younger licensed riders.
Registration and Inspection
Every moped used on public roads has to be registered. Registration is handled at the county level under Hawaii Revised Statutes § 249-14.1 rather than through the state motor vehicle system. The annual fee is $27, and the county issues a number plate that must be fastened to the rear of the moped and kept clean and fully visible. A tag or emblem issued at registration goes on the top right of the rear plate. Failing to register or renew brings a fine of up to $100 per violation.5Hawaii.gov. Hawaii Revised Statutes Chapter 249 – County Vehicular Taxes
Every moped also has to pass an annual safety inspection at a certified station. Hawaii Revised Statutes § 286-26 includes mopeds among the vehicles subject to yearly certification, and the station affixes an authorized sticker when the moped passes.6Justia. Hawaii Code 286-26 – Certificates of Inspection Riding without a current sticker can draw a citation.
If You Buy or Sell a Moped
When ownership changes, the seller must submit a notice of transfer to the county’s department of finance within ten days. Missing that deadline triggers a $100 fine.7County of Hawaii. Bicycle/Moped Notice of Transfer The buyer applies for transfer using the endorsed registration from the seller. In Honolulu the transfer fee is $10 within 30 days, and waiting longer adds a $50 penalty on top of that fee.8City and County of Honolulu. Vehicle Ownership Transfer
Where and How You Can Ride
Several of Hawaii’s moped rules catch new riders off guard, so it pays to know them before the first ride.
Stay to the Right, Single File
When moving slower than surrounding traffic, you must ride as far to the right of the roadway as safely possible. You can leave that position to prepare for a left turn, to avoid parked cars or debris, or when traveling on a one-way street with two or more lanes, where riding to the left is permitted. Riders always travel single file; side-by-side riding is not allowed.9Justia. Hawaii Code 291C-196 – Driving Mopeds on Roadways
Bicycle Lanes Are Mandatory
Where a roadway has a marked bicycle lane, moped riders must use it. The statute uses “shall,” not “may.” Counties can also restrict or prohibit moped use on separate bicycle paths, and any posted signs apply. Three-wheeled mopeds are exempt from the bicycle lane requirement.10Hawaii Department of Transportation. Information for MOPED Owners and Drivers
No Sidewalks, No Freeways
Mopeds are prohibited from sidewalks and any area intended for pedestrian use.9Justia. Hawaii Code 291C-196 – Driving Mopeds on Roadways Freeways are also off-limits. On-ramps are posted with signs prohibiting vehicles with engines under five horsepower, and the minimum freeway speed is 45 mph, both well above what a legal moped can achieve.10Hawaii Department of Transportation. Information for MOPED Owners and Drivers
Three-Wheeled Mopeds
Three-wheeled mopeds can only travel on roads with a posted speed limit of 35 mph or less.9Justia. Hawaii Code 291C-196 – Driving Mopeds on Roadways
Passengers
No passengers are allowed on a two-wheeled moped. The driver sits astride the seat, facing forward, with one leg on each side. A second seat on the vehicle does not change the rule.3Justia. Hawaii Code 291C-195 – Driving of Mopeds
The exception is a three-wheeled moped specifically designed to carry a driver and passenger seated side by side. On that type of vehicle the seating and passenger restrictions do not apply.3Justia. Hawaii Code 291C-195 – Driving of Mopeds
Helmets and Equipment
Riders under 18 must wear a safety helmet secured with a chin strap, meeting specifications set by the state’s director of transportation.3Justia. Hawaii Code 291C-195 – Driving of Mopeds Adults are not legally required to wear helmets. A helmet with a DOT certification label on the back meets the federal standard.11National Highway Traffic Safety Administration. Federal Motor Vehicle Safety Standard No. 218 – Motorcycle Helmets
Mopeds used on public roads should also have working headlamps, tail lamps, and rear reflectors. Riders without a windscreen are generally expected to wear eye protection such as safety glasses, goggles, or a face shield. These items factor into the annual safety inspection.
Insurance
Hawaii does not require liability insurance for standard two-wheeled mopeds. That leaves the rider personally responsible for the other party’s medical bills, property damage, and legal costs after a crash, and even a minor collision with a pedestrian can run beyond what most people can cover out of pocket.
Three-wheeled mopeds are different. The statute requires them to carry liability and property damage insurance, though personal injury protection is excluded.3Justia. Hawaii Code 291C-195 – Driving of Mopeds
Even where coverage is optional, a basic liability policy usually runs a few hundred dollars a year. If you are renting, ask what the rental company’s policy covers before you ride.
DUI Applies to Mopeds
Impaired driving laws cover mopeds. Hawaii’s DUI statute, § 291E-61, applies to moped operators, and a stop on a moped after drinking brings the same criminal penalties as a DUI in a car.12Justia. Hawaii Code 291E-61 – Operating a Vehicle Under the Influence of an Intoxicant A first offense can bring a 90-day license suspension, community service or jail time, and fines up to $1,000. Repeat offenses within five years escalate quickly, adding longer suspensions, mandatory jail, vehicle forfeiture, and, for habitual offenders, felony charges carrying up to five years of imprisonment.
A suspension hits moped riders especially hard because it bars you from driving any vehicle, not just the moped.
