Alcohol appears to be a factor in a two-vehicle collision in Ewa Beach Tuesday night that sent a 29-year-old man to a hospital in critical condition, Honolulu police said.

The crash occurred at the intersection of Fort Weaver Road and Kolowaka Drive at about 9 p.m.

Police said a pickup truck driven by the 29-year-old man was traveling north on Fort Weaver Road when he disregarded a red traffic signal at the intersection and collided head-on with a vehicle driven by a 63-year-old man.

The vehicle operated by the 63-year-old man was traveling south on Fort Weaver Road and turning onto Kolowaka Drive at the time.

Honolulu firefighters responded and extricated the 29-year-old man from his overturned truck. He was taken to a hospital in critical condition.

The driver of the other vehicle and his four passengers — a 35-year-old man, 33-year-old woman and two children visiting from the mainland — were taken to a hospital in good condition.

Police said alcohol was a factor in the collision.
