Investigation revealed that around 4:10 p.m., a 50-year-old male motorcyclist was speeding onto the off-ramp and then collided with the rear of another vehicle. As a result, he was ejected onto the roadway.

Paramedics provided advanced life-saving treatment at the scene before the man was then taken to the hospital.

However, HPD later confirmed that he had succumbed to his injuries and was pronounced dead.

Police said the motorcyclist was not wearing a helmet at the time of the collision.

This is the 19th traffic fatality on Oahu this year. At the same time in 2022, there were 16.

Two other motorists had died earlier in the day in two separate single-vehicle collisions.

The first incident happened at 1:25 a.m. when a 29-year-old man had failed to negotiate a right turn onto the Likelike Highway in Kaneohe and struck a concrete center median and then a metal guardrail.

Shortly after, police were called to the second fatal collision at 2:55 a.m. in the Kalihi area.

HPD said a 31-year-old male motorcyclist had veered right onto the roadway and collided with a metal guardrail. As a result, the man was ejected onto the road and died from his injuries.
