Man who died on H-1 was not buckled in

A 26-year-old Honolulu man died yesterday morning after he lost control of a speeding car which overturned and hit another car on H-1 freeway near the Alexander Street onramp, police said.

At 1:12 a.m., a 2007 white Toyota Camry driven by Stephen Yeh was speeding on the H-1 freeway's left-most lane near the Alexander Street onramp when the car swerved to avoid colliding with the vehicle in front of it, police said.

Yeh lost control of his car, which bounced off the barrier at the Alexander Street onramp and went back across three lanes of traffic before hitting the center median, overturning and hitting a 2008 black Mazdaspeed3, police said.

Police said the Mazdaspeed3's spoiler crashed through the rear window, injuring a 23-year-old woman seated in the back passenger seat.

Yeh was ejected from his car and pronounced dead at the scene. His passenger, a 26-year-old Ewa Beach man, had head and hand injuries, and was hospitalized in good condition.

Police said the passenger wore a seat belt, but Yeh did not.

The Mazdaspeed3's driver, a 24-year-old Honolulu man, and his front-seat passenger, a 23-year-old Honolulu man, were not injured. The woman in the back seat was taken to Straub Clinic and Hospital in good condition.

Police said it is not yet known whether Yeh was under the influence. An autopsy is scheduled for tomorrow.

Yeh is the 29th fatality on Oahu this year, compared with 41 at this time last year.
