A 26-year-old motorcyclist was killed Thursday following a collision on Kamehameha Highway near Ke Nui Road in Haleiwa.

The collision occurred around 4:45 p.m. when a man riding a motorcycle northbound attempted to overtake a vehicle driven by a 27-year-old woman traveling in front of him, according to the Honolulu Police Department’s Traffic Division, Vehicular Homicide Section.

As the driver made a left turn from Kamehameha Highway onto Ke Nui Road, the motorcyclist broadsided her vehicle, ejecting him onto the road, police said Friday.

Emergency responders treated the motorcyclist and took him to a hospital in critical condition, where he later died from his injuries.

The 27-year-old driver sustained minor injuries and was also transported to a hospital in good condition.

Police said the motorcyclist was not wearing a helmet at the time of the crash. HPD said speed was a factor in the crash, but drugs and alcohol were not involved.

This was the 39th traffic fatality on Oahu in 2024, down from 47 fatalities at the same time last year, HPD said.
