A 36-year-old man has died after he crashed into the rear of a pickup truck in Makaha Thursday night.

The Honolulu Medical Examiner’s Office has identified him as Kimo M. Peroff of Waianae. Autopsy results are pending to determine the exact cause of death.

Police said a 41-year-old Waianae man was driving a 2012 Toyota Tacoma pickup truck on the westbound lane of Farrington Highway when he slowed and stopped to reverse into the driveway of his residence at about 7:25 p.m.

Peroff was operating a moped and traveling westbound on the highway at a high rate of speed when he lost control and slid into the rear of the pickup truck.

Emergency Medical Services responded to the intersection of Farrington Highway and Kiapa Place.

Paramedics treated and transported Peroff in “extremely critical condition” to an area hospital where he was pronounced dead.

Police said speed was a factor. It’s unknown if alcohol or drugs were involved.

Peroff was not wearing a helmet at the time of the crash.

Police temporarily closed the highway between Moua and Upena streets to investigate.

This is the 34th traffic-related fatality compared to 22 at the same time last year.
