A 76-year-old man has died after a solo-vehicle crash in Kahuku Saturday night.

According to Honolulu police, the motorist was traveling east on Kamehameha Highway when he slowed down, veered off the roadway and crashed into the bushes along the highway’s right shoulder.

He was found unresponsive and transported to a hospital, where he was pronounced dead. His identity was not immediately released.

Police said he was wearing a seatbelt at the time of the crash. Speed does not appear to be a contributing factor, but it was unknown whether drugs or alcohol played roles in his death, police said.

The death was the No. 43 traffic fatality on Oahu this year compared with 38 at the same time last year. The investigation is ongoing, police said.
