A 36-year-old Waianae man died from injuries suffered on Saturday when the motorcycle he was operating collided with another motorcycle on Kalanianaole Highway near Sandy Beach.

Police said the man was traveling west on the highway around 10:30 a.m. when his motorcycle crashed into another motorcycle that had stopped in front of him. The rider, and the operator and passenger of the other motorcycle, were ejected from their motorcycles onto the roadway.

The man was taken in critical condition to a local trauma center, where he died.

The operator and passenger of the other motorcycle were also taken to a hospital, in serious and stable conditions, respectively.

Excessive speed and alcohol are not believed to have been factors in the incident, police said.

This was the 12th traffic-related fatality of the year on Oahu, compared with 13 at the same point last year.

Police closed Kalanianaole from Kealahou Street to the Waimanalo-side entrance of Sandy Beach for more than two hours while an investigation was conducted.
