The city medical examiner identified the man as Clifford Cuban of Kapolei.
The cause of death was a broken neck due to injuries he suffered in the crash on the H-1 Sunday night.
It happened around 7:30 p.m. in the east-bound direction on the H-1 freeway between the Makakilo and North-South Road.
According to police, the driver of a truck tried to overtake a car using the left shoulder lane, which consisted of loose dirt and grass.
The truck went out of control, crossed three lanes of traffic then slammed into a Mustang that was in the far right lane.
The truck then veered left, crossing three lanes again and hit the median.
The truck driver was pronounced dead at the scene.
The driver of the mustang, a 34-year-old man, and his 24-year-old female passenger were taken to the hospital in guarded condition.
Police say speed may have been a factor.
