The two-car accident at 2:27 a.m. left one person critically injured.

Traffic was diverted off the freeway at the Vineyard Boulevard off-ramp for nearly four hours following the accident.

A 17-year-old boy who drove a beige 1993 Ford Explorer was in critical condition following the crash and taken to The Queen's Medical Center, said police Capt. Evan Ching of the Traffic Division.

Police said the Explorer appears to have lost control and veered off the School Street off-ramp, plunging about 20 feet back onto the freeway. It then collided with a navy blue Lincoln Aviator.

A male passenger, 21, in the Explorer was taken to Kuakini Medical Center in stable condition.

The 28-year-old female driver of the Aviator was taken to Kuakini in stable condition, Ching said. A male passenger, 28, was not hospitalized.

Ching said the Explorer appears to have been heading west and gotten off at the School Street off-ramp. It then apparently veered left and crashed back onto the freeway. A guard rail was torn off and a chain-link fence was ripped where the Explorer apparently crashed through.

After hitting the freeway, it was struck by the Aviator.

The Explorer was on its roof when police arrived and one of its passengers was pinned under it. Firefighters helped paramedics pull the victim out of the Explorer. It is not clear if the Explorer landed on its roof or if it flipped from impact with the Aviator, Ching said.

The road was slippery at the time of the 2:27 a.m. accident.
