A 21-year-old moped rider was hospitalized in serious condition after a car struck him at the off-ramp connecting Kamehameha Highway to Nimitz Highway in Honolulu. Emergency crews responded shortly before midnight Wednesday.
According to Hawaii News Now, the rider was wearing a helmet. Emergency crews treated him at the scene and transported him for further care. Reports have not detailed what led to the collision or identified the car’s driver.
Crash Location
The collision happened on the off-ramp connecting Kamehameha Highway to Nimitz Highway in Honolulu.
A separate fatal motorcycle crash was reported on Sept. 15. Hawaii News Now reported that a 23-year-old motorcyclist died after a collision on the H-1 Freeway near Daniel K. Inouye International Airport; a 47-year-old motorist was also injured. That incident was distinct from Wednesday’s moped crash.
Helmet Use in Wednesday's Crash
Hawaii lawmakers changed the rules around moped safety gear last year. The Hawaii State Legislature enacted Act 222, effective June 25, 2025, mandating helmets for all moped operators regardless of age and barring anyone under 16 from operating one at all.

What Act 222 Requires
According to the Hawaiʻi State Senate Majority, Act 222 requires moped drivers to wear a safety helmet, prohibits people under 16 from driving a moped, and became effective on June 25, 2025.
HPD's Ongoing Push for Compliance
HPD's Ongoing Push for Compliance The Honolulu Police Department has been pressing the issue publicly. Under its “Safer Roads, Together” campaign, HPD reminded moped riders that helmets are mandatory for all ages after responding to multiple critical crashes involving unhelmeted riders that same month. Despite that outreach, compliance across Oahu has remained inconsistent throughout the year, based on the pattern of crashes police have logged since.
Hawaii law also limits standard two-wheeled mopeds to a single occupant, prohibiting passengers, and requires that operators hold a valid driver's license or a Class 1 moped license. Under Hawaii Revised Statutes § 286-2, a moped is defined as a two- or three-wheeled vehicle with a motor capacity of no more than 50cc or 2 horsepower and a top speed of 30 mph on level ground; anything faster or more powerful falls under separate motorcycle or scooter licensing rules. Privately owned mopeds are not legally required to carry auto insurance in Hawaii, meaning damages from crashes typically fall to the involved motorist's policy.
A Year of Mixed Progress on Oahu's Roads
The broader traffic safety picture on Oahu has actually improved in 2026. Oahu had 25 traffic fatalities, compared with 46 at the same point last year. That earlier year turned out to be historic for the wrong reasons: Oahu recorded 82 traffic fatalities in 2025, contributing to an 18-year statewide peak of 129 road deaths, according to Honolulu Civil Beat, with motorcycles and mopeds accounting for roughly a third of the island's fatal crashes.
The extent of his injuries and his current condition have not been further detailed beyond EMS's initial assessment.
