***ORIGINAL***

On September 1, 2024, at about 12:30 AM, a critical motor vehicle collision involving five vehicles occurred on the H-1 East freeway, in the Aiea area.

A 19-year-old male motorcyclist was traveling eastbound on the H-1 East freeway and rear-ended a 23-year-old male motorcyclist.  As a result of the collision both the 19-year-old and 23-year-old male motorcyclists were ejected onto the roadway. 

A 20-year-old male motorist stopped near the scene to assist when an unidentified motorist, traveling eastbound, struck both the 19-year-old motorcyclist and his motorcycle.  This secondary collision caused the motorcycle to collide into the stopped vehicle, operated by the 20-year-old male motorist. 

The unidentified motorist briefly stopped then continued eastbound without rendering aid or providing information. 

During the incident a 20-year-old female motorcycle passenger was struck by debris from the second collision.

As a result of the collision, the 19-year-old male motorcyclist was transported via Emergency Medical Services to an area hospital in critical condition. The 23-year-old motorcyclist was transported via private vehicle to an area hospital in good condition. The 20-year-old female motorcycle passenger was transported via private vehicle to an area hospital in good condition. The 20-year-old male motorist and his two passengers were not injured.

The 19-year-old male motorcyclist was wearing a helmet at the time of the collision.

At this time speed appears to be a contributing factor of this collision. It is unknown at this time if drugs or alcohol were contributing factor to this collision.

The investigation is ongoing.
