A 17-year-old motorcyclist who was critically injured in a motor vehicle crash Wednesday in Kuliouou died today.

Police said the teen was headed west on Kalanianaole Highway and disregarded a red traffic signal, and broadsided a vehicle that was headed eastbound and was turning left onto Kuliouou Road.

The 30-year-old male driver of the vehicle had the green light as he negotiated the turn, police said.

The motorcyclist crashed into the vehicle at about 11:45 p.m., and was taken to the hospital in critical condition.

The vehicle driver and his passenger, a 59-year-old woman were not injured.

Speed appears to be a contributing factor in the crash, police said.
