A Honolulu police officer, a 4-year-old, and two others were taken to the hospital this morning after a crash caused several collisions on Farrington Highway in Nanakuli, according to the Honolulu Police Department.

At about 8:40 a.m., a “critical multi-vehicle collision” occurred on Farrington Highway in Nanakuli.

HPD’s Traffic Division, Vehicular Homicide Section, received reports that an HPD officer was driving westbound on Farrington Highway when a 73-year-old man driving eastbound tried to make a left turn, crossed into the path of travel of the HPD officer, and got hit, the Star Advertiser reports.

The officer’s car was sent into the eastbound lanes where it “collided head-on with an eastbound vehicle operated by a 31-year-old male motorist, who was traveling with a 30-year-old female passenger and a juvenile passenger,” according to police.

The car driven by the 31-year-old man then hit a car driven by a 36-year-old man before colliding with another vehicle driven by a 39-year-old woman who had two kids on board.

The HPD officer and the 30-year-old female passenger from the third vehicle were transported to an area hospital in serious condition.
