A 36-year-old Pearl City man remained in The Queen's Medical Center this morning with critical injuries he suffered when the motorcycle he was riding crashed head-on at about 10:30 last night into a sport utility vehicle on Kaonohi Street.

Police traffic investigators said the man was traveling toward Honolulu on Kamehameha Highway when he made a left turn into oncoming traffic on Kaonohi Street and collided with a 2000 Nissan Xterra.

A 21-year-old woman driving the Xterra was not injured nor were her passengers, a woman, 20, and a man, 23.

Police said speed may have been a factor in the accident but had not determined whether alcohol or drugs played a part in the collision.

The motorcyclist was not wearing a helmet, police said.
